The incrimination of sand flies belonging to verrucarum species group in the leishmaniasis transmission underscores the need for a detailed information on the geographical distribution of these species. The current listing adds 34 new records that extend significantly the knowledge of the geographical distribution of the verrucarum group in Colombia. The most important new records pertain to Lutzomyia spinicrassa in the tropical dry forest of the Atlantic coast, Lutzomyia ovallesi in the Orinoco and Amazon River watersheds regions of Colombia, and the sympatric occurrence of Lutzomyia spinicrassa and Lutzomyia quasitownsendi in the eastern chain of the Andes mountains. Additionally, the municipal and altitudinal distributions are compiled for 19 new species recorded for Colombia. The series townsendi of the verrucarum group generally restricted to premontane and lower montane zones based on distribution data on Lutzomyia longiflocosa, L. quasitownsendi, Lutzomyia sauroida, L. spinicrassa, Lutzomyia torvida, Lutzomyia townsendi and Lutzomyia youngi. The series verrucarum is distributed from the tropical lowland to the montane zones, and includes species with wide geographical range (Lutzomyia evansi, Lutzomyia columbiana, L. ovallesi, Lutzomyia nuneztovari, Lutzomyia nevesi), and species of highly endemic distribution (Lutzomyia andina, Lutzomyia disiuncta, Lutzomyia moralesi, Lutzomyia antioquiensis). Members of the series pia (Lutzomyia pia, Lutzomyia limafalcaoae) and the series serrana (Lutzomyia serrana) occur from the tropical lowlands to the lower montane zones. The altitudinal divergences may be intrinsically tied to speciation process, especially as it relates to the climatic and geologic events that have affected the flora and fauna of the Andean region.

Anastrepha fraterculus (Wied) is the most important fruit fly in Colombia. It has been trapped from the sea level up to 2000 m of altitude, but is is more abundant in the coffee growing area located at 1300 to 1700 masl, with temperatures between 18 to 22 deg. C (-min 11 deg. C,-max 25 deg. C). The main host in that area is Coffea arabica L., but it also has 14 additional identified hosts that belong to 9 families. In the hot climates from 0 to 1000 m of altitude it breeds in mango (Mangifera indica L.) and guava (Psidium guayava L:). The pest has not been stabilised in the cultivated upper lands between 2300-2600 masl. (author)

Full Text Available On July 2002, a study of some physicochemical parameters and their relationship with the benthonic macroinvertebrates community structure on four coriotypes: stone, trash, silt and macrophytes, was carried out in Pozo Azul (Gaira River basin, Magdalena, Colombia. The physicochemical parameters were determined, to a considerable extent, by the geographic characteristics of the system. The water was found to be oxygen saturated, and intermediate compounds of the organic matter stabilization, such as nitrites and ammonium, there were found 588 individuals distributed in 11 orders and 38 families. The most representative orders were Trichoptera, Coleoptera, Diptera and Ephemeroptera. The most representative families were Baetidae, Simullidae, Perlidae, Chironomidae, and Hydropsychidae, in this rank of abundance. The BMWP index for the relationship between the community structure and the water quality (adapted by Universidad del Valle, Cali, Colombia was calculated. According to this index the water quality was optimum. Also, given the general characteristics of the site studied, the water mass quality was classified as good and oligosaprobit, based on the saprobit ecology. It is possible that this state was reached due to stabilization after a small perturbation induced by coffee cultivation in the zone.

2009-03-01

Although cases of leishmaniasis have been reported in the province of Guaviare, Colombia, no entomological studies were included to identify the Lutzomyia sand fly vector species in that area. Lutzomyia species were identified from four townships of Guaviare. Probable vectors were named based on those species involved in transmission in other areas. Sampling was undertaken with CDC light traps suspended at heights between 1.5 m and 9 m. Additional sand flies were collected with Shannon traps and by aspiration of adult flies from daytime resting sites. Sand flies belonging to 37 different species were collected. 35 of them were recorded for the first time in Guaviare Province. Four species were new records for Colombia: Lutzomyia begonae, L. campbelli, L. sericea and L. nematoducta. The most abundant species were L. hirsuta 24.3% (148/610), L. yuilli 15.2% (93/610), L. davisi 10.3% (63/610), followed by L. fartigi, L. carrerai, L. antunesi, L. flaviscutellata and L. olmeca bicolor. Seven of these species of have been associated previously with endemic or epidemic transmission of leishmaniasis.

Polyacrylamide gel electrophoresis was used to elucidate genetic variation at 13 isozyme loci among forest populations of Lutzomyia shannoni from three widely separated locations in Colombia: Palambí (Nariño Department), Cimitarra (Santander Department) and Chinácota (Norte de Santander Department). These samples were compared with a laboratory colony originating from the Magdalena Valley in Central Colombia. The mean heterozygosity ranged from 16 to 22%, with 2.1 to 2.6 alleles detected per locus. Nei's genetic distances among populations were low, ranging from 0.011 to 0.049. The estimated number of migrants (Nm=3.8) based on Wright's F-Statistic, F ST, indicated low levels of gene flow among Lu. shannoni forest populations. This low level of migration indicates that the spread of stomatitis virus occurs via infected host, not by infected insect. In the colony sample of 79 individuals, the Gpi locus was homozygotic (0.62/0.62) in all females and heterozygotic (0.62/0.72) in all males. Although this phenomenon is probably a consequence of colonization, it indicates that Gpi is linked to a sex determining locus.

Larvae of Empididae (Diptera) prey on black fly immatures and its pupae can be collected from pupal cases of Simuliidae (Diptera). The aim of our work was to report the second record of association between immatures of Empididae and Simuliidae in the Neotropical Region and the first for the Atlantic Forest (Rio de Janeiro, Brazil). We collected 4982 pupae and exuviae of Simulium Latreille, (Diptera, Simuliidae) and found three with a pupa of Hemerodromia Meigen (Diptera, Empididae) inside. This shows that the use of black flies cocoons by dance flies occurs at extremely low frequencies, which might explain why this association is so rarely recorded. Our results are relevant for a better comprehension of the predator-prey relationship between these families. Copyright © 2016 Elsevier B.V. All rights reserved.

Garcia, Juan Carlos; Velasquez, Leonardo Lucas; Cardenas Henao, Heiber; Posso Gomez, Carmen Elisa

2012-01-01

We studied the diet of the rain frog Pristimantis jubatus based on stomach and intestinal contents of 29 individuals from three different localities at Munchique National Park, Colombia. The diet was composed exclusively of arthropods, comprising a total of 66 preys which were in 32 taxa. The most frequent dietary items were Diptera and Hymenoptera, 19.7 % and 16.7 % respectively, followed by Araneae (15.1 %) and Coleoptera (12.1 %). Plant consumption was considered incidental because of its low frequency. This species showed no preference for any type of prey, with a high value of niche breadth (0.68) indicating a generalist diet. Adults and juveniles occupy different perch height. Habitat use and the variety of items found show P. jubatus as a species that can consume any kind of arthropod available in the strata of the forest where it is foraging.

Ecoepidemiological studies of cutaneous leishmaniasis and regular monitoring of Lutzomyia species have generated a knowledge base that can be used for control and prevention strategies targeted at the disease transmission dynamics in focal areas of Colombia. In this study, the presence and spatial distribution of phlebotomines of medical importance in the municipalities of Tierralta (El Loro and Tuis Tuis villages) and Valencia (Guadua and Mieles villages) were determined. Entomological surveys were performed in 2015 (months of June, September and November) and samples were collected via CDC-traps located in intradomicilary and peridomiciliary areas in the municipalities of Tierralta and Valencia (Department of Córdoba, Colombia). Active searches were also carried out with a mouth aspirator to collect adult phlebotomines from resting sites. ANOVA and Kruskal-Wallis tests were performed to assess if the differences between the communities of phlebotomines. Spatial distribution maps of the Lutzomyia species were generated. A high species diversity of Lutzomyia was observed with a total of 1677 Lutzomyia individuals belonging to 12 species. Among these species, Lu. panamensis was the most abundant (80.18%). The composition of the intradomicilary and peridomiciliary phlebotomines varied significantly (F = 0.9962; df = 1; p = 0.02895). Species like Lu. carpenteri, Lu. camposi, Lu. dysponeta, Lu. atroclavata and Lu. yuilli yuilli were recorded for the first time in the Department of Córdoba, Colombia. The spatial distribution shows that Lu. panamensis and Lu. gomezi are predominant and present in areas with high concentration of houses. This study provides basic information on new records of phlebotomines in the Department of Córdoba. The results suggest that greater vector-human contact occurs in the peridomiciliary environment and that a high number of Lutzomyia species associated with the transmission of leishmaniasis are present in Colombia.

Full Text Available The morphologically similar taxa Anopheles calderoni, Anopheles punctimacula, Anopheles malefactor and Anopheles guarao are commonly misidentified. Isofamilies collected in Valle de Cauca, Colombia, showed morphological characters most similar to An. calderoni, a species which has never previously been reported in Colombia. Although discontinuity of the postsubcostal pale spots on the costa (C and first radial (R1 wing veins is purportedly diagnostic for An. calderoni, the degree of overlap of the distal postsubcostal spot on C and R1 were variable in Colombian specimens (0.003-0.024. In addition, in 98.2% of larvae, seta 1-X was located off the saddle and seta 3-C had 4-7 branches in 86.7% of specimens examined. Correlation of DNA sequences of the second internal transcribed spacer and mtDNA cytochrome c oxidase subunit I gene (COI barcodes (658 bp of the COI gene generated from Colombian progeny material and wild-caught mosquitoes from Ecuador with those from the Peruvian type series of An. calderoni confirmed new country records. DNA barcodes generated for the closely related taxa, An. malefactor and An. punctimacula are also presented for the first time. Examination of museum specimens at the University of the Valle, Colombia, revealed the presence of An. calderoni in inland localities across Colombia and at elevations up to 1113 m.

ITS2 for the identification of Calliphoridae (Diptera: Calliphoridae of forensic importance in Colombia

2016-09-01

Full Text Available Forensic entomology is a discipline that uses insects to obtain useful information for the determination of the postmortem interval (PMI. Flies of the family Calliphoridae are extensively used for this purpose, however, the identification of these flies can be difficult when the individual is not an adult or when it is incomplete. In the present work, we tested the utility of the ITS2 region of the nuclear genome for the identification of Calliphoridae species in Colombia using three approaches: comparing genetic distances using the barcoding methodology, with a phylogenetic reconstruction, and with PCR-RFLPs. We sequenced 520 bp in 44 individuals belonging to 16 species of califorids. Intraspecific and interspecific distance values were calculated using the K2P model. The intraspecific distance values ranged between 0 and 0.252 %, while the interspecific distance values ranged between 3.6 and 18.9 %, indicating that this gene can be used as a genetic barcode for the identification of species of the Calliphoridae family. Both the Neighbour-Joining and Bayesian analyses recovered 90 % of the genera as monophyletic, with pp values between 0.89 and 1. Blepharicnema splendens was always recovered within the Lucilia genera. Based on the obtained sequences we used the NEBCutter application to identify four restriction enzymes that cut in a differential way and generated useful patterns for the identification of the species. The enzymes were successfully tested and confirmed the utility of this technique as a fast way to identify species of Calliphoridae in Colombia.

The departments of Chocó and Antioquia in Colombia show climatic and vegetation conditions favoring the establishment of vector species of the genus Lutzomyia and the transmission of Leishmania spp. to human populations entering conserved forest environments. To report the species of Phlebotomine sandflies present in three natural reserves in the Darien and Pacific regions of Colombia. Sand flies were collected specifically in the natural reserves El Aguacate (Acandí, Chocó), Nabugá (Bahía Solano, Chocó) and Tulenapa (Carepa, Antioquia). Sand flies were collected with CDC light traps, active search in resting places and Shannon traps. The taxonomic determination of species was based on taxonomic keys. For some species of taxonomic interest, we evaluated the partial sequences of the 5' region of COI gene. A total of 611 adult sand flies were collected: 531 in Acandí, 45 in Carepa and 35 in Bahía Solano. Seventeen species of the genus Lutzomyia, three of the genus Brumptomyia and one of the genus Warileya were identified. The genetic distances (K2P) and grouping supported (>99%) in the neighbor joining dendrogram were consistent for most established molecular operational taxonomic units (MOTU) of the Aragaoi group and clearly confirmed the identity of Lu. coutinhoi. Species that have importance in the transmission of leishmaniasis in Acandí, Bahía Solano and Carepa were identified. The presence of Lu. coutinhoi was confirmed and consolidated in Colombia.

Full Text Available Recently, populations of flies have increased in numbers given the elevated levels of organic matter waste produced by anthropic activities and domestication of animals. Such increase represents a worldwide health concern, since flies can be vectors of human diseases. The great variety of feeding and developmental habits of flies of the family Sarcophagidae taking place on animal corpses, feces and decomposed organic matter make them potential vectors of pathogens. Herein, we evaluated the synanthropic index (SI, as well as other ecological aspects of this family, through simultaneous monthly samplings in three areas with different degrees of human disturbance (urban, rural and forest. Each area had four van Someren Rydon traps, each one with a different bait (i.e., human feces, chicken viscera, fish and decomposing onion. Traps were active during 48 hours each month, and specimen collection was made every 12 hours. A total of 7 446 Sarcophagidae individuals were collected (1 275 males and 6 171 females, belonging to 27 species and nine genera. Tricharaea (Sarcophagula canuta (SI=+96.67, Oxysarcodexia taitensis (SI=+93.85, Peckia (Peckia chrysostoma (SI=+90.00 and Tricharaea (Sarcophagula occidua (SI=+88.76 exhibited the highest values of synanthropy index, revealing a strong preference for human settlements.

This report of background notes for Colombia concentrates on political history, but also summarizes geography, people, economy, defense and foreign relations. Colombia, linking Panama to the northwest tip of South America, has 26.5 million people, growing at 1.3% per year, expected to be the third most populous nationon the continent soon. Infant mortality rate is 65/1000 and life expectancy is 62 years. Literacy is reported at 80% although less than 40% of children complete 2.5 years of school. Geographically, Colombia has flat coastal areas, several mountain ranges, highlands and hot eastern plains. 70% of the population live in cities. There are 2 major political parties, in existence since the early 19th century. Recently there have been violent inter-party differences, punctuated by even more contentious guerrilla attacks. Colombia possesses resources of oil, gas coal, nickel, gold, emeralds, platinum, iron. Agricultural products are dominated by coffee, but also include a wide variety of tropical and temperate grains, fruits, vegetables, dairy and meat products, timber and flowers.

Montoya-Lerma, J; Cadena, H; Segura, I; Travi, B L

1999-01-01

In Colombia, Leishmania mexicana has a scattered geographical distribution and no sand fly vectors have been associated with its transmission. During the present study, the anthropophilic sand fly Lutzomyia columbiana was found to be the only species collected using diverse methods, in a small focus of Le. mexicana in the municipality of Samaniego, SW Colombia. Ecological data indicate that this sand fly species is present in both peri and intradomestic habitats, where it readily bites man. Further evidence comes from experimental infections of wild-caught Lu. columbiana with Le. mexicana after feeding on infected hamsters. Based on these results, it is suggested that this sand fly is the most likely vector in the study area, suggesting the existence of a previously unknown sand fly-parasite association.

Aedes albopictus is the second most important dengue virus vector in the Asian southeast after Aedes aegypti. Its entrance into the Americas occurred in 1985, and laboratory studies performed show its potential as a vector in this continent as well. In Colombia, this species has been reported in Leticia (Amazonas) in 1998 and Buenaventura (Valle del Cauca) in 2001. The latest discoveries show that this mosquito continues to advance toward the country's interior. To inform that the presence of A. albopictus is documented in the city of Cali, Valle del Cauca, Colombia. Since 2002, weekly sampling has been performed using larval traps located at seventeen stations. The identification of the A. albopictus species, was carried out in the Unidad de Entomología, Laboratorio de Salud Pública Departamental. These identifications were confirmed in the Entomology Laboratory at Universidad del Valle and the National Institute of Health in Bogotá. From April to June of 2006, larvae of A. albopictus were found in six sampling stations located between northwest and northeast of Cali, one of them in the suburban area of the Yumbo city. The control of A. aegypti and A. albopictus must be integrated into a single program. The surveillance in the cities and nearest departments must be intensified with the objective of limiting the advancement of A. albopictus.

The location of the microhabitats where immature phlebotomine sand flies of the genus Lutzomyia develop is one of the least-known aspects of this group of medically important insects. For this reason strategies of source reduction approach for their control have not been possible in contrast to other insect vectors (such as mosquitoes), because their juvenile stages in terrestrial microhabitats is difficult to detect. Direct examination of soil samples, incubation of substrates and the use of emergence traps were the methods used to identify juvenile stages in 160 soil samples from urban and forest habitats within the foci of Leishmania transmission in Colombia. Immatures collected were identified subsequent from the rearing and emergence of adults using taxonomic keys or the analysis of the mitochondrial marker cytochrome oxidase I. Plant species associated with the natural breeding sites were identified and physicochemical properties of the soils were analyzed. A total of 38 (23.7%) sampling sites were identified as breeding sites, 142 phlebotomine sand flies were identified, belonging to 13 species of the genus Lutzomyia and two of Brumptomyia. The greatest numbers of immature were found within the tabular roots (51 immature sand flies from eight positive sites) and bases of trees (35 immature sand flies from 11 sites). The characterization and presence of the tree species (mainly Ceiba pentadra, Anacardium excelsum, Pseudosamanea guachapale) and the physicochemical properties (relative humidity and carbon/nitrogen ratio) of the soils associated with these breeding sites are significant factors in explaining the diversity and abundance of phlebotomine sand flies. Immature phlebotomine sand flies of the genus Lutzomyia in Colombia can be found in a wide variety of breeding sites rich in organic matter, high relative humidity and are associated with a typical vegetation of each locality. These results provide new perspectives for the study of the ecology of the

1998-01-01

Lutzomyia longipalpis (Lutz & Neiva), the sand fly vector of American visceral leishmaniasis in the New World tropics, has a broad but discontinuous geographical distribution from southern Mexico to Argentina. A baseline for population genetic structure and genetic variability for this species was obtained by analyzing 5 local, peridomestic populations at the approximate center of its distribution, the Magdalena River Valley of central Colombia. Three populations of L. longipalpis from El Callejón, a small rural community, were compared with 2 populations from neighboring areas 12 and 25 km distant for genetic variation at 15 isoenzyme loci. The mean heterozygosity ranged from 11 to 16%, with 1.2 to 2.3 alleles detected per locus. Nei's genetic distances among the populations were very low, ranging from 0.001 to 0.007. Gene flow estimates based on FST indicated high levels of gene flow among local L. longipalpis populations, with minimal population substructuring.

The Chironomidae is a cosmopolitan family of Nematoceran flies with more than 20,000 species described. However the diversity of genera and species of the family in the Andean region beyond the 2,000 m.a.s.l are scarcely known. We conducted faunal surveys and biomonitoring research in different streams of Colombia, Ecuador and Peru from May 2005 to October 2011. Based on specimens collections, a taxonomic key was developed to identify pupae and pupal exuviae of 46 genera of midges (Diptera, Chironomidae) collected from streams at high altitude areas on the Andean tropical mountains. We included illustrations and brief taxonomic descriptions for all genera, of which several ones have not yet been formally described; in this latter case we used the nomenclature of Roback & Coffman (1983). For two genera, Cricotopus and Genus 1, keys to the most com- mon morphospecies were provided. Results showed that in this area the chironomid assemblages are dominated by the members of the subfamily Orthocladiinae (22 genera) followed by the Chironominae (13). Six genera of Tanypodinae were identified, while only three and two genera were present from subfamilies Podonominae and Diamesinae. This key may be very useful for both studies about drift in streams, and for biomonitoring purposes.

Terrorism in Colombia.

Science.gov (United States)

Paredes Zapata, Gabriel Darío

2003-01-01

Colombia is a poor country that has been plagued by ongoing violence for more than 120 years. During the 1940s, subversive terrorist groups emerged in rural areas of the country when criminal groups came under the influence of Communism, and were later transformed into contemporary groups, such as the Ejercito de Liberacion Nacional (ELN) or National Liberation Army and Fuerzas Armadas Revolucionares de Colombia (FARC) or Revolutionary Armed Forces of Colombia). Paramilitary terrorist groups emerged in response to subversive groups and were later transformed into contemporary groups, such as the Autodefensas Unidas de Colombia (AUC) or United Self-Defense Forces of Colombia. Terrorism has placed an enormous burden on modern Colombia. From 1995 to 2002, 9,435 people were killed by terrorism-related events, of which 5,864 were killed by subversive terrorist activities and 3,571 were killed by paramilitary terrorist activities. In 2002, at least nineteen attacks produced 10 or more casualties, of which 18 were bombings. In 2002, terrorists killed at least 12 mayors, 71 legislators, and internally displaced 300,000 persons from their homes. Since terrorist groups in Colombia are typically supported by drug manufacturing and trafficking, it has been difficult at times to distinguish violence due to terrorism from violence due to illicit drug trafficking. Terrorism has also had a major adverse effect on the economy, with restricted travel, loss of economic resources, and lack of economic investment. In addition to political, military, and commercial targets, terrorists have specifically targeted healthcare infrastructure and personnel. At the national and local levels, much emergency planning and preparedness has taken place for terrorism-related events. The Centro Regulador de Urgencias (CRU) or Emergency Regulation Center in Bogota plays a major role in coordinating local prehospital and hospital emergency response in the capital city and the national level where

Genetic variation among natural and laboratory colony populations of Lutzomyia longipalpis (Lutz & Neiva, 1912)(Diptera: Psychodidae) from Colombia.

Genetic diversity among three field populations of Lutzomyia longipalpis in Colombia was studied using isozyme analysis. Study sites were as much as 598 km apart and included populations separated by the eastern Cordillera of the Andes. Genetic variability among populations, estimated by heterozygosity, was within values typical for insects in general (8.1%). Heterozygosity for field populations were compared with a laboratory colony from Colombia (Melgar colony) and were only slightly lower. These results suggest that establishment and long term maintenance of the Melgar colony has had little effect on the level of isozyme variability it carries. Genetic divergences between populations was evaluated using estimates of genetic distance. Genetic divergence among the three field populations was low (D = 0.021), suggesting they represent local populations within a single species. Genetic distance between field populations and the Melgar colony was also low (D = 0.016), suggesting that this colony population does not depart significantly from natural populations. Finally, comparisons were made between Colombian populations and colonies from Brazil and Costa Rica. Genetic distance values were high between Colombian and both Brazil and Costa Rica colony populations (D = 0.199 and 0.098 respectively) providing additional support for our earlier report that populations from the three countries represent distinct species.

Full Text Available The family Calliphoridae is widely known to lead the colonization of corpses and their development rates are frequently used to estimate the postmortem interval. This study presents the larval growth of five forensically important species of Calliphoridae in Colombia. Rearing took place in semicontrolled field conditions where the egg masses were collected. We show curves of larval growth, larval length and time intervals to reach all immature stages for Lucilia eximia and Cochliomyia macellaria at two sites with different climatic conditions and for Chrysomya albiceps, Chrysomya megacephala and Calliphora nigribasis at one site. Overall, high temperatures speeded up the development of the species reared at two different sites, whereas low temperatures for C. nigribasis, lengthened the total development time. Differences between this study and others can be explained by the experimental conditions in the field without the possibility of strict laboratory rearing controls.La familia Calliphoridae es ampliamente conocida por liderar la colonización de los cadáveres y sus tasas de desarrollo son frecuentemente utilizadas para estimar el intervalo postmortem.

James Montoya-Lerma

1998-03-01

Full Text Available The sandfly Lutzomyia evansi from a focus of visceral leishmaniasis in northern Colombia was reared and maintained under laboratory conditions for five generations. The average time for total development was 41.8 days (range = 35.1- 49.6 at 25 oC and 89-95% of relative humidity. The mean number of eggs laid was lower in laboratory bred females either in pots (13.2 eggs/female or vials (29.9 eggs/female than in wild caught females (33.4 eggs/female. Immature mortality, mainly due to fungal and mite contamination, was higher during the first two instars than in the remaining immature stages. Adults were robust and healthy although difficult to feed on hamster or chick skin membrane. In summary, Lu. evansi is a colonizable species but requires specific conditions.

Full Text Available Random amplified polymorphic DNA (RAPD markers were used to analyze 119 DNA samples of three Colombian Anopheles nuneztovari populations to study genetic variation and structure. Genetic diversity, estimated from heterozygosity, averaged 0.34. Genetic flow was greater between the two populations located in Western Colombia (F ST: 0.035; Nm: 6.8 but lower between these two and the northeastern population (F ST: 0.08; Nm: 2.8. According to molecular variance analysis, the genetic distance between populations was significant (phiST 0.1131, P < 0.001. The variation among individuals within populations (phiST 0.8869, P < 0.001was also significant, suggesting a greater degree of population subdivision, not considered in this study. Both the parameters evaluated and the genetic flow suggest that Colombian An. nuneztovari populations are co-specific.

The male of this species is differentiated from other members of the series sanguinaria based on the following combination of characters: (i) base of coxite with 0–3 subequal setae, (ii) spines of gonostyle organized in positions 2.1.2, (iii) spines inserted on distal half of gonostyle and (iv) relationship of alar indices. The female is recognized principally by the following characters: (i) palpomere V longer than III, (ii) length of labro-epipharynx and (iii) relationship of the alar indices. PMID:23295748

La metodología investigativa se fundamenta en la recolección y el análisis de datos derivados de investigaciones anteriores. Los resultados son significativos en lamedida que presentan el estado de las migraciones en Colombia entre los siglos XVI y XIX y desde la primera mitad del siglo XX hasta la actualidad. Por un lado, engloban a la inmigración británica, jamaiquina y africana en las islas de San Andrés y Providencia; junto con la inmigración árabe, judía, alemana, francesa, italiana y gitana en Colombia continental. Por otro, aluden a las migraciones japonesas, suramericanas, junto con los crecientes asentamientos de migrantes norteamericanos, europeos y las nuevas oleadas de migraciones asiáticas y africanas en Colombia. Todo ello lleva a aprehender la envergadura del papel jugado por Colombia como un país de destino de las migraciones internacionales, lo que contrasta con la imagen más conocida de Colombia como un país expulsor de emigrantes.

Full Text Available Lutzomyia antunesi has been commonly reported in outbreaks of cutaneous leishmaniasis (CL in the Orinoquia region of Colombia. The bionomics of this species were studied in the municipality of Villavicencio (Meta, Colombia. Sandflies were captured over the course of one week per month for one year in intradomiciliary, peridomiciliary and extradomiciliary housing areas. The captures were performed from 06:00 pm-06:00 am using CDC light traps and the females were processed for polymerase chain reaction (PCR to detect Leishmania spp. A total of 22,097 specimens and 19 species were captured of which Lu. antunesi (89% and Lutzomyia walkeri (5% were the most abundant. Other species recognised as anthropophilic (Lutzomyia panamensis, Lutzomyia gomezi, Lutzomyia flaviscutellata and Lutzomyia fairtigi were present in very low abundance (< 2%. Natural infection with Leishmania spp was detected using PCR in Lu. antunesi, Lu. panamensis and Lu. flavicutellata, showing infection rates of 1%, 4.8% and 7.5%, respectively. The present paper provides information on various ecological aspects of Lu. antunesi. An analysis of seasonality shows that this species increases in abundance in the hottest months (December, January and February, directly correlating with the maximum temperature and inversely correlating with precipitation. The natural infection rate is associated with the peaks of highest abundance.

Lutzomyia species of the subgenus Sciopemyia show restricted distribution and are rarely represented in sand fly captures, with the exception of L. sordellii, which is found from Costa Rica to Argentina. To date, only two of these species. L. sordellii and L. preclara have been reported in Colombia. The female of L. vattierae was redescribed and the record of this Sciopemyia species established for in the Colombian national park, serranía de La Macarena. The study was carried out in the Serrania de La Macarena, in western province of Meta. The serrania is a small mountain range situated between the Orinoco and Amazon River basins and geographically separated from the Andes. Sand flies were collected during two consecutive nights with a CDC light trap placed from 18:00 to 06:00 hours in a primary forest. Four females belonging to the subgenus Sciopemyia were identified as L. vattierae, which differs from L. preclara by the presence of papillae on the third flagellomere and from L. sordellii by the form and length of the spermathecae and individual sperm ducts. The number of known species of Sciopemyia in Colombia is now three and include L. sordellii, L. preclara, and L. vattierae.

[Means of the formation of gonotrophic relations in blood-sucking Diptera].

Science.gov (United States)

Tamarina, N A

1987-01-01

Gonotrophic relations in low and higher bloodsucking Diptera are fundamentally different that results from an initial type of feeding and trophic behaviour. Trophic behaviour of low dipterous hematophages and gonotrophic harmony peculiar to them can be traced from entomophagy, that is from the predatory mode of life on account of small insects. By the type of the trophic behaviour low bloodsucking Diptera are predators with a typical moment contact with the prey. More primitive is a type of gonotrophic harmony characteristic of hunters for diffusely spread prey (incomplete blood portion provides the maturation of incomplete portion of eggs). Hunting for diffusely spread prey is characteristic of entomophages too. The appearance of gregarious ruminants facilitates the possibility of repeated contacts with prey and blood satiation threshold increases. This is a higher type of gonotrophic harmony providing a maximum realization of potential fecundity. The initial saprophagy of higher Diptera is associated with another type of trophic behaviour (long contact with food substratum) that is a prerequisite for quite a different way of evolution of host-parasite relationships in higher Diptera. This leads to more close connections with the host and excludes gonotrophic harmony. Females were the first to begin the exploitation of vertebrate animals. This is connected with the peculiarities of their behaviour during egg laying such as the stay near animals for laying eggs into fresh dung. Autogeneity, nectarophagy and aphagia are homologous phenomena which reflect the loss of an animal component of food or both components at the level of non-specialized saprophagy rather than secondary loss of bloodsucking. The scheme of gonotrophic relations is given.

Full Text Available Introduction. Because the role of Aedes albopictus as an incriminated vector of several viral pathogens, its control is important to human health. To establish appropriate control methods, characterization of the larval habitats is a necessary first step.
Objective. Habitats of the immature stages of Ae. albopictus were characterized with respect to physical-chemical parameters and by floral and faunal arrays present.
Materials and methods. Leticia is located at the southernmost tip of Colombia on the banks of the Amazon River. In the urban area, 154 houses were inspected in December 2002 and January 2003. Physical-chemical data were collected, including exposure to sunlight, location, container size and material, water conductivity, and dissolved oxygen. Macroinvertebrates and plankton samples were taken at each positive larval site. The results were compared using descriptive analysis, principal component analysis, classification dendrograms, and diversity indexes.
Results. Twenty-one habitats were found positive for Diptera, and 13 were positive for Ae. albopictus larvae. Most of the positive habitats (92% were located near the houses--they were small or medium size receptacles located in the shade. This water generally had low conductivity and low turbidity, although high values of these parameters were also identified. The habitats had low diversity indexes for macroinvertebrates and high diversity indexes for plankton. In the principal component analysis, significant correlation was found with mites, oligochaetes and hemipterans (the macroinvertebrates and with bacilarophyceaes, clorophyceaes and cianophyceas (the algal forms.
Conclusion. In Leticia, females of Ae. albopictus were found in newly established habitats with sufficient availability of resources, low conductivity, and turbidity, lower intra-and interspecific competition.Introducción. Dada la importancia de Aedes albopictus en la salud pública, es necesario

Although once associated only with rural areas, the American leishmaniasis vectors now appear to be associated also with urban and suburban areas of the Neotropics. Following the appearance of the first autochthonous visceral and cutaneous leishmaniasis cases in the urban area of the city of Sincelejo, Colombia, a preliminary entomological survey of the sand fly species composition was performed using Shannon and CDC light traps. A total of 486 sand flies representing six Lutzomyia species were collected. L. evansi, L. panamensis and L. gomezi, known vectors of Leishmania spp. were the predominant sand fly species around dwellings. The finding of these species in relation to the appearance of the first cases of leishmaniasis in the city mentioned is discussed.

Full Text Available We conducted a survey of insects and pest management practices on 34 farms growing ornamental tropical foliage plants in the central coffee region of Colombia over two years. Tropical foliage provided habitat for a diverse range of insects. In total, phytophagous or detritivorous insects from six orders, 40 families and 62 genera were collected. The most common were Hemiptera (29 genera from 16 families, followed by Coleoptera (17 genera from 4 families, Diptera (5 genera from 5 families, Lepidoptera (5 genera from 4 families, Hymenoptera (3 genera from 2 families and Orthoptera (2 genera from 2 families. The most common phytophagous species were leaf cutting ants (Atta and Acromyrmex spp., leaf beetles (Chrysomelidae, leafhoppers (Cicadellidae, stinkbugs (Pentatomidae, squash bugs (Coreidae, tree hoppers (Membracidae and plant hoppers (Fulgoridae. Beneficial insects identified from tropical foliage included predators and parasitoids amongst 5 orders, 12 families and 22 genera. The most abundant were predators among the Coccinellidae, Chrysopidae, Reduviidae, Lycidae and Formicidae but only low numbers of parasitoids (Ichneumonidae, Braconidae and Tachinidae were collected. A pest management questionnaire given to growers revealed a preponderance of reliance on broad spectrum insecticides with a smaller number of growers (approximately one third also using some biological control methods. Our survey contributes basic information regarding diversity of Neotropical insects associated with ornamental foliage plants.

Following the appearance of the first autochthonous visceral and cutaneous leishmaniasis cases in the urban area of the city of Sincelejo, Colombia, a preliminary entomological survey of the sand fly species composition was performed using Shannon and CDC light traps. A total of 486 sand flies representing six Lutzomyia species were collected. L. evansi, L. panamensis and L. gomezi, known vectors of Leishmania spp. were the predominant sand fly species around dwellings. The finding of these species in relation to the appearance of the first cases of leishmaniasis in the city mentioned is discussed.

Internal displacement in Colombia: Fifteen distinguishing features.

Shultz, James M; Ceballos, Ángela Milena Gómez; Espinel, Zelde; Oliveros, Sofia Rios; Fonseca, Maria Fernanda; Florez, Luis Jorge Hernandez

This commentary aims to delineate the distinguishing features of conflict-induced internal displacement in the nation of Colombia, South America. Even as Colombia is currently implementing a spectrum of legal, social, economic, and health programs for "victims of armed conflict," with particular focus on internally displaced persons (IDPs), the dynamics of forced migration on a mass scale within this country are little known beyond national borders.   The authors of this commentary are embarking on a global mental health research program in Bogota, Colombia to define best practices for reaching the displaced population and implementing sustainable, evidence-based screening and intervention for common mental disorders. Presenting the defining characteristics of internal displacement in Colombia provides the context for our work and, more importantly, conveys the compelling and complex nature of this humanitarian crisis. We attempt to demonstrate Colombia's unique position within the global patterning of internal displacement.

Most reports published in the field of forensic entomology are focused on Diptera and neglect the Hymenoptera community. However, Hymenoptera are part of the entomofaunal colonization of a dead body. The use of Hymenoptera parasitoids in forensic entomology can be relevant to evaluate the time of death. Hymenoptera parasitoids of the larvae and pupae of flies may play an important role in the estimation of the post-mortem period because their time of attack is often restricted to a small, well-defined window of time in the development of the host insect. However, these parasitoids can interfere with the developmental times of colonizing Diptera, and therefore a better understanding of their ecology is needed. The work reported here monitored the presence of adult Hymenoptera parasitoids on decaying pig carcasses in an urban biotope during the summer season (from May to September). Six families and six species of parasitoids were recorded in the field: Aspilota fuscicornis Haliday (Braconidae), Alysia manducator Panzer, Nasonia vitripennis Walker (Pteromalidae), Tachinaephagus zealandicus Ashmead (Encyrtidae), Trichopria sp. (Diapriidae), and Figites sp. (Figitidae). In the laboratory, five species emerged from pupae collected in the field: Trichopria sp., Figites sp., A. manducator, N. vitripennis, and T. zealandicus. These five species colonize a broad spectrum of Diptera hosts, including those species associated with decomposing carcasses, namely those from the families Calliphoridae, Muscidae, Fanniidae, and Sarcophagidae.

Anastrepha striata is widely distributed across the Americas and is a pest of economically important crops, especially crops of the Myrtaceae family. Insect population structures can be influenced by the presence of physical barriers or characteristics associated with habitat differences. This study evaluated the effect of the Western Andes on the population structure of A. striata. Individuals were collected from Psidium guajava fruits from three natural regions of southwestern Colombia (Pacific Coast, mountainous region and the inter-Andean valley of the Cauca River). Based on a 1318 bp concatenated of the genes Cytochrome Oxidase subunit I (COI) and NADH dehydrogenase subunit 6 (ND6), 14 haplotypes with few changes among them (between 1 and 3) were found. There was only one dominant haplotype in all three regions. No genetic structure associated with the three eco-geographical regions of the study was found. Moreover, the Western Andes are not an effective barrier for the genetic isolation of the populations from the Pacific Coast compared with the inter-Andean valley populations. This genetic homogeneity could be partially due to anthropogenic intervention, which acts as a dispersal agent of infested fruits. Another hypothesis to explain the lack of structure would be the relatively recent arrival of A. striata to the region, as indicated by an analysis of the demographic history, which reveals a process of population expansion. This study represents the first attempt to understand the population genetics of A. striata in Colombia and could contribute to the integral management of this pest.

The dual burden of malnutrition in Colombia.

Almost all nutrition policies in Colombia currently focus on either undernutrition or obesity, with the predominant emphasis on undernutrition. It is crucial to assess the prevalence of the dual burden of malnutrition in Colombia to better target programs and policies. The aim was to estimate the national prevalence of the dual burden of malnutrition in Colombia at the individual and household levels in children aged malnutrition was defined as the coexistence of overweight and stunting or anemia in the same person or household. In Colombia, low to high prevalences of overweight and obesity (3.4-51.2%) coexist with moderate to high prevalences of anemia (8.1-27.5%) and stunting (13.2%). The observed prevalence of the dual burden was lower than expected. Approximately 5% of households had at least one stunted child aged malnutrition in Colombia are lower than expected. Despite the independence of the occurrence of these conditions, the fact that the dual burden coexists at the national, household, and intraindividual levels suggests that public policies should address both conditions through multiple strategies. It is imperative to evaluate the current nutrition policies to inform malnutrition prevention efforts in Colombia and to share lessons with other countries at a similar stage of nutritional transition. © 2014 American Society for Nutrition.

Violence and health in Colombia Violencia y salud en Colombia

Full Text Available In Colombia, violence seems uncontrollable. Along with massacres and group killings of astonishing cruelty, there are also kidnappings and disappearances, abuse of children and the elderly, and rape of young adolescents. Every day, without respite, Colombians are witnesses or victims of street crimes as well as racial, sexual, and socioeconomic discrimination. Unwillingly, they become agents of aggression in public transport, at home, at school, and at work. Colombia has the highest rates of mortality from homicide in the world. Apart from the enormous institutional burden that violence imposes on the health services and forensic medicine, it now constitutes the principal public health problem in the country. To confront it, the health sector must develop policies and finance actions, develop innovative ways to train personnel, implement public education processes, and devote more effort and greater creativity to research, which up to now has provided some important, albeit insufficient, responses. Violence, which is the substitution of force for any type of dialogue, must be considered within the context of life and health. Doing so is not an attempt to rationalize violence, much less to substitute words or reflection for action, but rather an attempt to understand it in depth in order to search for alternatives. With that goal, this article analyzes the subject of violence in Colombia, principally from the perspective of its effect on the health of the citizens and its implications for the health sector. The author fully recognizes the subjectivity and limitations of the views he expresses herein.La violencia en Colombia parece incontenible.

Full Text Available La violencia en Colombia parece incontenible. A las masacres y asesinatos colectivos, de una crueldad desconcertante, se suman los secuestros y desapariciones, el maltrato de niños y ancianos y las violaciones de adolescentes. Cada día, sin tregua, los colombianos son espectadores o víctimas de atracos callejeros y de discriminación racial, sexual y socioeconómica. Sin quererlo, se convierten en agentes de agresiones en el transporte urbano, el hogar, la escuela y el trabajo. Colombia tiene las tasas de mortalidad por homicidio más altas del mundo. Independientemente de la enorme sobrecarga institucional que impone a los servicios de salud y medicina legal, la violencia constituye actualmente en Colombia el principal problema de salud pública. Para hacerle frente, el sector de la salud debe elaborar políticas y financiar acciones; crear nuevos procesos de formación de personal, poner en marcha procesos de educación pública, y dedicar mayor esfuerzo y creatividad al campo de la investigación, que hasta ahora ha dado respuestas importantes pero aún insuficientes. Al reflexionar sobre la violencia, que es la sustitución de toda argumentación por la fuerza, es necesario ubicarla en el contexto de la vida y la salud. No se pretende solo racionalizarla, y menos aún sustituir la acción por la palabra o por las reflexiones, sino tratar de comprenderla a fondo con el objeto de buscarle alternativas. En el presente artículo se analiza, con esta finalidad, el tema de la violencia en Colombia, principalmente desde el punto de vista de su efecto en la salud de los colombianos y de sus implicaciones para el sector sanitario.

Diptera of sanitary importance associated with composting of biosolids in Argentina

Directory of Open Access Journals (Sweden)

Valeria Alejandra Labud

2003-12-01

Full Text Available OBJECTIVE: Odorous compounds produced at the biosolids composting plant in Bariloche (NW Patagonia attract a variety of insects, mainly belonging to the order Diptera. In order to characterize these flies, collected specimens were taxonomically identified, their community characteristics were described and their sanitary and synanthropic importance and autochthonous or introduced character were determined. METHODS: Sampling was performed from October 1999 until March 2000. Adults were collected using an entomological net, and larvae and puparia were obtained from the composting material and incubated to obtain adults. Richness, abundance and sex ratio were calculated. RESULTS: A total of 9 taxa of Diptera were identified: Sarconesia chlorogaster, Phaenicia sericata, Calliphora vicina, Cochliomya macellaria, Ophyra sp, Muscina stabulans, Musca domestica, Sarcophaga sp and Fannia sp. Specimens of Anthomyiidae, Acaliptratae and one larva of Eristalis tenax were also found. Ophyra sp. was the most abundant taxa. All the captured Diptera belonged to introduced taxa. Most of them are considered to be eusynanthropic and/or hemisynanthropic and have sanitary importance as they may cause myiasis and pseudomyiasis. The high number of females registered and the finding of immature stages indicated that flies can develop their complete life cycle on biosolid composting windrows. CONCLUSIONS: The characterization of flies obtained in this study may be useful for defining locations of urban or semi-urban composting facilities. It also highlights the importance of sanitary precautions at such plants.

Aedes aegypti is a vector for the dengue virus in Colombia. Its productivity can be estimated using pupal counts. To determine Ae. aegypti productivity in households and public spaces in Girardot (Colombia) during both wet and dry seasons. The amount of Ae. aegypti pupae was evaluated in 20 randomly selected clusters in Girardot, each consisting of 100 households and public spaces. Inspections were performed during the rainy (February-May, 2011), and dry (August-September, 2011) seasons. House, container, Breteau, person and hectare pupae indices were estimated. During the rainy season households contributed 94% to the total number of pupae (n=7,098) while only 6% (n=482) were found in public spaces. In the dry season, 98% (n=9,138) of pupae were found in households and 2% (n=223), in public spaces. Low water-storage tanks and tanks for washing purposes provided >87% of pupae in households, whereas jars, tires and sinks contained most pupae in public spaces. High pupal densities were observed in public spaces during the rainy season and in streets and schools in the dry season. There were no significant differences in the index per person (rainy season=1.0; dry season=1.3) or per hectare (rainy season=0.96, dry season=0.45) between seasons. High Ae. aegypti pupal densities were found inside households in low water-storage tanks and tanks for washing purposes during both the dry and rainy seasons. Public spaces provided more aquatic habitats during the rainy season. Vector control strategies targeting these containers could allow a more rational use of resources and increase efficiency.

A total of 4,840 phlebotomine sand flies from 54 localities in Putumayo department (=state), in the Colombian Amazon region, were collected in Shannon traps, CDC light traps, resting places and from human baits. At least 42 Lutzomyia species were registered for the first time to the department. Psychodopygus and Nyssomyia were the subgenera with the greatest number of taxa, the most common species being L. (N.) yuilli and L. (N.) pajoti. They were sympatric in a wide zone of Putumayo, indicating that they should be treated as full species (new status). Among the anthropophilic sand flies, L. gomezi and L. yuilli were found in intradomiciliar, peridomestic, urban or forest habitats. L. richardwardi, L. claustrei, L. nocticola and L. micropyga are reported for the first time in the Colombian Amazon basin. L. pajoti, L. sipani and L. yucumensis are new records for Colombia.

1995-07-01

Ecological studies on the sand fly Lutzomyia longipalpis (Lutz & Neiva) were conducted during 1990-1993 in a small rural community in Colombia where American visceral leishmaniasis is endemic. Standardized weekly sand fly collections made from pigpens and natural resting sites displayed a bimodal annual abundance cycle, with a small peak occurring in October-November and a larger one in April-May. Time series analysis was employed to quantify the associations between sand fly abundance and weather factors (temperature, relative humidity, and rainfall). In addition to a prominent 6-mo cycle. Fourier analysis of the collection data demonstrated that the L. longipalpis population also exhibited a 5- to 8-wk cycle that may represent the length of larval development. Autoregressive moving average models were fit to weekly collection data and their residuals were regressed against rainfall, temperature, and relative humidity. A significant positive association between female L. longipalpis abundance and the relative humidity and rainfall recorded 3 wk earlier was found, indicating that these factors may be of value in predicting sand fly abundance. Additionally, these data indicated that L. longipalpis larvae may become quiescent during adverse conditions.

Sampling took place in two rural, one suburban and two urban habitats in and around Frankfurt (Main), Germany, lasting two years and eight months. Highest values for species richness and Chao-Shen entropy estimator for Shannon's index in both families were found at the urban sites, peaking during summer. Space-time interaction was tested and found to be significant, demonstrating the value of a statistical approach recently developed for community surveys in ecology. K-means partitioning and analysis of indicator species gave significant temporal and habitat associations of particular taxa. Calliphora vicina was an indicator species for lower temperatures without being associated with a particular habitat. Lucilia sericata was an indicator for urban sites, whereas Lucilia ampullacea and Lucilia caesar were indicators for rural sites, supplemented by the less frequent species Calliphora vomitoria. Sarcophagidae were observed during a clearly shorter period of year. Sarcophaga subvicina+Sarcophaga variegata was found to be an indicator for urban habitats during summer as well as Sarcophaga albiceps for rural habitats. A significant association of Sarcophaga caerulescens to rural habitats as well as one of Sarcophaga similis to urban habitats was observed. Copyright © 2013 Elsevier Ireland Ltd.

Environmental occurrence of arsenic in Colombia: A review

International Nuclear Information System (INIS)

Alonso, David L.; Latorre, Sergio; Castillo, Elianna; Brandão, Pedro F.B.

2014-01-01

The international literature on the presence of arsenic (As) in Latin America does not disclose the true magnitude of the presence of As in Colombia. In this paper, we summarize the literature on As occurrence in Colombia. The data reveal that As is present in matrices such as soil, sediments and water and in the food chain. Some of the As concentrations exceed the limits specified by national and international regulations. Arsenic higher concentrations are associated with mining regions (e.g., soils, up to 148 mg/kg; sediments, up to 1400 mg/kg) and agricultural areas (e.g., vegetables, up to 5.40 mg/kg; irrigation water, up to 255 μg/L), and underscore the potential human and environmental risks associated with the presence of As in the country. This review highlights the importance of focusing research on understanding the occurrence, origin and distribution of As in Colombia to better understand its environmental and public health impact. -- Highlights: • Information about arsenic (As) studies in Colombia is provided. • Occurrence of As in Colombia. • Compilation help to increase knowledge of As presence in Latin America. • Need for more research on the occurrence, origin, distribution, speciation and remediation of As in Colombia. -- This review communicates the untold story of arsenic in Colombia and draws attention to the need for more rigorous research on the metalloid. It also contributes to the information available on As in Latin America

We examined changes in the phlebotomine fauna resulting from human intervention in a tropical dry forest of Northern Colombia where visceral and cutaneous leishmaniases are endemic. A natural forest reserve (Colosó) and a highly degraded area (San Andrés de Sotavento [SAS]) were sampled monthly for 8 mo using Shannon traps, sticky traps, and resting-site collections. Overall abundances were higher in Colosó (15,988) than in SAS (2,324). and species richness of phlebotomines was greater in the forest reserve (11 species) than in the degraded habitat (seven species). Fisher alpha, a measure of diversity, reinforced this trend. Both sand fly communities were dominated by Lutzomyia evansi (Nuòez-Tovar), vector of Leishmania chagasi (Cunha & Chagas), representing 92 and 81% of all captures in Colosó and SAS, respectively. Lutzomyia longipalpis (Lutz & Neiva), the common vector of visceral leishmaniasis, accounted for 4-7% of the sand fly community. Lutzornyia panamensis (Shannon) and Lutzomya gomezi (Nitzulescu), putative vectors of Leishmania braziliensis (Vianna), had low abundances at both study sites. The zoophilic species Lutzomyia cayennensis (Floch & Abonneuc) and Lutzomyia trinidadensis (Newstead) were present in variable numbers according to trapping methods and site. Habitat degradation negatively affected sand fly communities, but medically important species were able to exploit modified environments, thereby contributing to Lishmania endemicity.

Lutzomyia evansi is the vector of Leishmania chagasi in northern Colombia. Differences in feeding success were revealed, when this phlebotomine sand fly was fed on five species of small mammal hosts from an endemic focus of visceral leishmaniasis. In each trial, 50 female sand flies were provided access to similar-sized depilated areas of the hind foot of each of 44 individual mammals and allowed to feed for 30 minutes. The number of engorged sand flies was counted at the end of each trial and compared among host species by analysis of variance and Tukey's multiple comparisons test. Sand flies fed least successfully on Sciurus granatensis, a common squirrel in the endemic area. It has not been found infected with L. chagasi. Intermediate numbers of sand flies engorged on Heteromys anomalus and Zygodontomys brevicauda, but these two mammals have not been found infected with L. chagasi and are not expected to be important in transmission. Sand flies fed most successfully on Didelphis marsupialis and Proechimys canicollis. These are the two most abundant mammals in the endemic area and frequently are infected. Results provided further evidence that these two species are the wild mammals with the greatest impact on transmission of L. chagasi in northern Colombia.

Tabanidae and other Diptera on Camel’s Hump Vermont: Ecological Observations

2011-11-01

Full Text Available A canopy trap and aerial nets led to finding 8 species of Tabanidae. There was an abundance of calyptrate muscoid flies. Camel’s Hump is in the Green Mountains of western New England, USA. Discovering Diptera on Camel’s Hump involved sixteen visits over 40 years. Upwards of 23 other Diptera species are listed. Habitats on the east side and above 762 m (2500 ft elevation on Camel’s Hump differ from the west slope but the boreal forest on both sides is influenced by cloud and fog precipitation on trees. The cliffs just above the 900 m level along the east side are often overlooked, are not seen from the summit and provide access to morning sun for insects. Recent visits explored the role of polarized skylight in relation to the canopy trap, the boreal forest environment and flies found there.

Members of the megadiverse insect order Diptera (flies) have successfully colonized all continents and nearly all habitats. There are more than 154 000 described fly species, representing 1012% of animal species. Elucidating the phylogenetic relationships of such a large component of global...... biodiversity is challenging, but significant advances have been made in the last few decades. Since Hennig first discussed the monophyly of major groupings, Diptera has attracted much study, but most researchers have used non-numerical qualitative methods to assess morphological data. More recently......, quantitative phylogenetic methods have been used on both morphological and molecular data. All previous quantitative morphological studies addressed narrower phylogenetic problems, often below the suborder or infraorder level.

Diptera Brachycera found inside the esophagus of a mummified adult male from the early XIX century, Lisbon, Portugal

2008-03-01

Full Text Available Fly puparia and adult fragments of diptera muscid were found inside the esophagus of a mummified body from the early XIX century, buried inside the crypt of the Sacrament Church (Lisbon, Portugal. The identification of the material revealed a monospecific colonization by Ophyra capensis (Wiedemann (Diptera: Muscidae, a species known to invade corpses in the ammoniacal fermentation wave. This species can be found in corpses kept indoors, not available to the early waves of blowflies (Diptera: Calliphoridae. In the present case, the number of pupae and their developmental stage suggest that the female invaded the mummified corpse through the partially opened mouth and the oviposition took place directly inside the esophagus. This is the first case of O. capensis infesting internal organs of an intact corpse. The use of chemical products for the embalming process probably explains why external colonization did not occur.

Information about mosquito ecology in the high mountain ecosystems of the Neotropical region is sparse. In general, few genera and species have been reported in these ecosystems and there is no information available on habitats and the mosquitoes occupying them. In the present study, specimens collected from NW Colombia in HME were grouped using larval habitat data via an Operational Taxonomic Unit (OTU) determination. A total of 719 mosquitoes was analyzed belonging to 44 OTUs. The analysis considered habitat features and clustered the specimens into six groups from A-F. Five of these included species from different genera, suggesting common habitat requirements. Group E with four genera, seven subgenera, and six species occupied the highest areas (above 3,000 m), whereas three groups (B, D, F) were detected at lower altitudes (1,960-2,002 m). Bromeliads were the most common larval habitat, with 47% (335/719) of the specimens; five genera, six subgenera, and eight species were identified and classified into 66% (29/44) of the OTUs. This work showed some similarities to the habitat requirements and provides a grouping system that constitutes an important baseline for the classification of mosquito fauna from high mountain ecosystems according to altitude and larval habitat. © 2018 The Society for Vector Ecology.

Aedes albopictus is widely distributed around the world. Its introduction to the Americas occurred in 1985 and it is considered a potential vector of dengue viruses and one of the principal vectors of chikungunya virus. In Colombia, this species was reported for the first time in Leticia (Amazonas) in 1998, followed by Buenaventura (Valle del Cauca) in 2001, Barrancabermeja (Santander) in 2010, and Medellín (Antioquia) in 2011. So far, this species has been reported in ten departments of the country. Objective: To report the finding of A. albopictus in the city of Istmina, Chocó, and its implications for public health. Materials and methods: In January 2015, we conducted an inspection of immature stages of Aedes spp. in breeding sites in the neighborhoods of San Agustín, Santa Genoveva and Subestación in Istmina, Chocó. The immature stages collected in this municipality were identified at the Unidad de Entomología of the Laboratorio de Salud Pública Departamental de Chocó, and confirmed by the Laboratorio de Entomología, Red Nacional de Laboratorios, Instituto Nacional de Salud, in Bogotá. In January 2015, twelve A. albopictus larvae were found in the breeding sites located in Subestación and San Agustín neighborhoods. The occurrence of A. albopictus in the municipality of Istmina underlines the importance of strengthening continuous entomological surveillance strategies at national and local levels in the country, especially in Istmina and its surrounding municipalities.

1995-09-01

Nocturnal activity of the sand fly Lutzomyia longipalpis (Lutz & Neiva) was studied from August 1991 to July 1992 in a small rural community in Colombia where American visceral leishmaniasis is endemic. During 2 or 3 nights each month, sand flies were collected with hand-held aspirators each hour between 1730 and 0630 hours, from a pigpen and a cattle corral located 30 m apart. Host-seeking activity of L. longipalpis adults was characterized by 2 general patterns: (1) adult sand fly activity increased shortly after sunset and continued until just after sunrise, and (2) peak sand fly activity was greatest early in the evening (1830-2330 hours) and then declined steadily toward morning. Female L. longipalpis activity generally increased after 2030 hours, whereas that of males remained constant or declined as the evening progressed. There were seasonal differences in sand fly abundance between the 2 sites: peak abundance in the cattle corral occurred during hot, dry periods, whereas maximum abundance in the pigpen occurred when relative humidity was higher. Influence of relative humidity on activity varied with season. Sand fly activity tended to decrease at temperatures below 24 degrees C and increase in the presence of moonlight.

Full Text Available OBJETIVOS: Describir las tendencias de la mortalidad por suicidios en Colombia en el período de 1985 a 2002, analizar su comportamiento según el sexo, el grupo de edad y el mecanismo de lesión y calcular los años de vida potencial perdidos (AVPP por suicidios en ese período. MÉTODOS: Se calcularon las tasas de mortalidad crudas, específicas por edad y sexo y ajustadas por la edad, a partir de la información de mortalidad y población de las bases de datos oficiales del Departamento Administrativo Nacional de Estadística de Colombia. Se estimaron los AVPP, corregidos por el impacto social, la edad y la mala calidad de los registros de muertes. La tabulación de los resultados se realizó según los códigos X600-X849 y Y870 de la décima revisión de la Clasificación Estadística Internacional de Enfermedades y Problemas Relacionados con la Salud (CIE-10 y los códigos E950-E959 de la novena revisión (CIE-9. RESULTADOS: Se observó un aumento considerable en las tasas de suicidios en Colombia a partir de 1998, particularmente en la población de adultos jóvenes y en hombres. Las tasas más altas en los hombres se observaron en los grupos de 20 a 29 años y de mayores de 70, con un incremento en el tiempo. En las mujeres, las tasas más altas se registraron en el grupo de 10 a 19 años. La proporción de AVPP por suicidios aumentó de 0,81% en 1981 a 2,20% en 2002. En los hombres, los principales mecanismos de lesión fueron las heridas por armas de fuego y explosivos, el ahorcamiento y el envenenamiento, con un aumento relativo del ahorcamiento, mientras que en las mujeres fue el envenenamiento. CONCLUSIONES: Se confirmó la tendencia ascendente en la tasa de suicidios en Colombia, especialmente en el segmento de la población laboralmente activa, lo que conlleva un drástico incremento en los AVPP.OBJECTIVES: To report trends in mortality from suicide in Colombia from 1985 to 2002 by sex, age group, and method, and determine the

Con el propósito de establecer el probable origen de una población urbana del vector, detectada en años recientes, se caracterizaron genéticamente ejemplares de Lutzomyia evansi de siete localidades geográficas del Caribe Colombiano. Los flebotomíneos fueron recolectados en ambientes rurales y urbanos de zonas endémicas y no endémicas de leishmaniasis visceral. Dentro del fragmento secuenciado de 315 pb correspondiente al extremo 3’ del gen mitocondrial citocromo b, se encontraron nueve sitios polimórficos, nueve haplotipos nucleotídicos y un solo haplotipo aminoacídico. Las distancias genéticas pareadas entre los haplotipos, estimadas con el modelo de Kimura de dos parámetros, oscilaron entre 0,0032 y 0,0194. El análisis reveló la existencia de una baja variabilidad genética entre especímenes de localidades urbanas y rurales. Varios de los flebotomíneos recolectados en la zona urbana de la ciudad de Sincelejo, departamento de Sucre, donde en años recientes aparecieron casos autóctonos de leishmaniasis visceral, fueron genéticamente similares a los de El Contento, en el cercano departamento de Córdoba, foco rural de la enfermedad. Se discuten las implicaciones epidemiológicas de este hallazgo para la transmisión de Leishmania infantum en el Caribe Colombiano.

Garfield, Richard; Llanten Morales, Claudia Patricia

2004-10-01

Among the countries of the Americas, Colombia has the highest level of deaths due to homicides and armed conflict. The objective of this research was to combine and contrast information from various sources on deaths due to violence in Colombia in order to identify major trends in violence in the country and to compare those trends with those in other nations of the Americas. We drew together information from a wide array of sources, including the Government of Colombia, Colombian forensic institutions, nongovernmental organizations, and international research centers. We considered the impact of the violence on mortality as well as in such areas as nonfatal injuries, displacement of persons, and kidnappings. While there have been many deaths in Colombia directly related to military conflict, there have been many more deaths and injuries as an indirect result of war. The highest levels of deaths directly related to violence occurred during the 1990-1995 period. Although deaths due directly to armed conflict declined in the late 1990s, the related events of kidnappings and displacement did not. Efforts to reduce the violence-related suffering in Colombia must consider both direct and indirect causes of mortality as well as nonfatal outcomes such as kidnappings and displacement.

2015-09-01

In forensic entomology, larval rearing usually includes the presence of biological contaminants including scuttle flies (Diptera: Phoridae). Scuttle flies are recognized as forensically important insects and have been reported causing nuisance and contamination in laboratory environments. This paper reports for the first time the finding of multiple scuttle fly species affecting colonies of third instar larvae of the Oriental latrine blowfly, Chrysomya megacephala (Fabricius) (Diptera: Calliphoridae), reared indoors at the Forensic Science Simulation Site, Universiti Kebangsaan Malaysia. Adult scuttle flies were discovered inside a rearing container after the emergence of adult C. megacephala., The scuttle fly species are Megaselia scalaris (Loew), M. spiracularis Schmitz and Puliciphora borinquenensis (Wheeler). Notes on the life history and biology of these species are discussed herein.

The population sizes of Anopheles gambiae Giles (Diptera: Culicidae) and Anopheles arabiensis Patton (Diptera: Culicidae) increase dramatically with the onset of the rainy season in sub-Saharan Africa, but the ecological mechanisms underlying the increases are not well understood. As a first step toward to understand, we investigated the proliferation of algae, the major food of mosquito larvae, in artificial fresh water bodies exposed to sunlight for a short period, and old water bodies exposed to sunlight for a long period, and the effects thereof on the development of these anopheline larvae. We found that an epizoic green algal species of the genus Rhopalosolen (Chlorophyta: Chlorophyceae) proliferated immediately after water freshly taken from a spring was placed in sunlight. This alga proliferated only briefly (for ~10 d) even if the water was repeatedly exposed to sunlight. However, various algal species were observed in water that remained under sunlight for 40 d or longer (i.e., in old water bodies). The growth performance of larvae was higher in sunlight-exposed (alga-rich) water than in shade-stored (alga-poor) water. Stable isotope analysis suggested that these two anopheline species fed on Rhopalosolen algae in fresh water bodies but hardly at all on other algae occurring in the old water bodies. We concluded that freshly formed ground water pools facilitate high production of anopheline species because of the proliferation of Rhopalosolen algae therein, and the increase in the number of such pools in the rainy season, followed by rapid increases in A. gambiae and A. arabiensis numbers. © The Author(s) 2018.

Established procedures for collecting and preserving evidence are essential for all forensic disciplines to be accepted in court and by the forensic community at large. Entomological evidence, such as Diptera larvae, are primarily preserved in ethanol, which can evaporate over time, resulting in the dehydration of specimens. In this study, methods used for rehydrating specimens were compared. The changes in larval specimens with respect to larval length and weight for three forensically important blow fly (Diptera: Calliphoridae) species in North America were quantified. Phormia regina (Meigen), Cochliomyia macellaria (F.), and Chrysomya rufifacies (Macquart) third-instar larvae were collected from various decomposing animals and preserved with three preservation methods (80% ethanol, 70% isopropyl alcohol, and hot-water kill then 80% ethanol). Preservative solutions were allowed to evaporate. Rehydration was attempted with either of the following: 80% ethanol, commercial trisodium phosphate substitute solution, or 0.5% trisodium phosphate solution. All three methods partially restored weight and length of specimens recorded before preservation. Analysis of variance results indicated that effects of preservation, rehydration treatment, and collection animal were different in each species. The interaction between preservative method and rehydration treatment had a significant effect on both P. regina and C. macellaria larval length and weight. In addition, there was a significant interaction effect of collection animal on larval C. macellaria measurements. No significant effect was observed in C. rufifacies larval length or weight among the preservatives or treatments. These methods could be used to establish a standard operating procedure for dealing with dehydrated larval specimens in forensic investigations.

In this century it took off and it consolidated their industry of the hydrocarbons and with her great part of the industrialization process and development of the country. It is undeniable that the petroleum was one of the big main characters of the century X X and Colombia has not been unaware to the sways of a highly changing industry. The creation of the OPEC, the warlike conflicts, the times of high and low prices, the technological advances, the processes of energy integration and the mega coalitions are hardly some of the ingredients that seasoned the Oil Industry in the years 1900

The diversity of necrophagous Diptera is largely unknown in seasonally dry tropical forests, despite their medical, veterinary, and forensic relevance. We performed a study in the dry Caatinga forest exclusive to Brazil in order to assess the diversity and temporal pattern of Diptera species using pig carcasses as substrates. Adults were collected daily until complete skeletonization. We collected 17,142 adults from 18 families, 10 of which comprise species with known necrophagous habits. The most abundant families were Calliphoridae (47.3% of specimens), Sarcophagidae (20.8%), and Muscidae (15.5%), whereas Sarcophagidae stood out in terms of richness with 21 species. The native Cochliomyia macellaria (F.) (Diptera: Calliphoridae) and the invasive Chrysomya albiceps (Wiedmann) (Calliphoridae) were the dominant species. A total of 18 species reached the carcass during the first 48 h postdeath. The bloated and active decay stages had the highest richness and abundance of dipterans. From a forensic standpoint, C. macellaria and C. albiceps are likely to aid in establishing postmortem interval due to their early arrival and high abundance on the carcass. Despite harsh environmental conditions, the Caatinga harbors a rich assemblage of dipterans that play a key role in carrion decomposition. Their medico-veterinary importance is strengthened by the poor local sanitary conditions. © The Authors 2016. Published by Oxford University Press on behalf of Entomological Society of America.

Full Text Available La imagen país de Colombia ha sido objeto de discusión en los campos de los negocios internacionales y el marketing territorial. Colombia es un país con un posicionamiento tradicional asociado al narcotráfico y al café, situación que ha llevado a los gobiernos de la última década a definir nuevas estrategias que ayuden a mejorar la reputación del país en mercados internacionales. Sin embargo, sus esfuerzos han sido de poco impacto porque la imagen país de Colombia todavía mantiene una asociación histórica negativa resultado del narcotráfico. En este sentido, el presente artículo aborda los resultados de una investigación realizada sobre las impresiones que tienen los mexicanos que han visitado y no han visitado a Colombia. Se eligió a México porque es el segundo emisor de turistas hacia Colombia procedentes de Norteamérica. Por medio de una investigación empírica aplicada a una muestra de 190 mexicanos mayores de 18 años, se encontró que el posicionamiento se mantiene negativo y se asocia al país con drogas, terrorismo, inseguridad y corrupción. Dicha percepción contrasta con un atributo que se destaca en el estudio, y es que se asocia a Colombia con la amabilidad de su población.

Full Text Available Sarcosaprophagous macroinvertebrates (earthworms, termites and a number of Diptera larvae enhance changes in the physical and chemical properties of organic matter during degradation and stabilization processes in composting, causing a decrease in the molecular weights of compounds. This activity makes these organisms excellent recyclers of organic matter. This article evaluates the succession of insects associated with the decomposition of solid urban waste separated at the source. The study was carried out in the city of Medellin, Colombia. A total of 11,732 individuals were determined, belonging to the classes Insecta and Arachnida. Species of three orders of Insecta were identified, Diptera, Coleoptera and Hymenoptera. Diptera corresponding to 98.5% of the total, was the most abundant and diverse group, with 16 families (Calliphoridae, Drosophilidae, Psychodidae, Fanniidae, Muscidae, Milichiidae, Ulidiidae, Scatopsidae, Sepsidae, Sphaeroceridae, Heleomyzidae, Stratiomyidae, Syrphidae, Phoridae, Tephritidae and Curtonotidae followed by Coleoptera with five families (Carabidae, Staphylinidae, Ptiliidae, Hydrophilidae and Phalacaridae. Three stages were observed during the composting process, allowing species associated with each stage to be identified. Other species were also present throughout the whole process. In terms of number of species, Diptera was the most important group observed, particularly Ornidia obesa, considered a highly invasive species, and Hermetia illuscens, both reported as beneficial for decomposition of organic matter.

1997-11-01

An intensive search for the larval habitats of Lutzomyia longipalpis (Lutz & Neiva) was conducted from November 1992 to October 1993 at a small rural community in Colombia where American visceral leishmaniasis is endemic. Emergence traps constructed from polyvinyl chloride pipes were used to sample a variety of soil microhabitats that included edge areas of covered pigpens, cattle corrals, the base of trees, and leaf litter at sites within 40 m of a house, rocks in fields located between 50 and 500 m from houses, and sites within a patch of secondary forest (rocks, base of palm trees, and leaf litter). The teneral status of the sand flies captured in the emergence traps was confirmed by laboratory studies that determined the rate of terminalia rotation in male L. longipalpis and the rate of cuticular growth layer formation of the thoracic phragma in both sexes of this species. A total of 58 teneral sand flies was captured during the study period (49 wk). Fifteen specimens were L. longipalpis; of these 11 (5 sand flies per square meter) were captured near pigpens, 3 (1.4 sand flies per square meter) were captured near rock resting sites, and 1 (1.6 sand flies per square meter) was collected at the base of a tree. The remainder of the sand flies were either L. trinidadensis (Newstead) or L. cayennensis (Flock & Abonnenc). Our results indicate that L. longipalpis larvae were dispersed widely in sites near houses, rather than concentrated in a few optimal microhabitats.

Full Text Available La violencia en Colombia parece incontenible. A las masacres y asesinatos colectivos, de una crueldad desconcertante, se suman los secuestros y desapariciones, el maltrato de niños y ancianos y las violaciones de adolescentes. Cada día, sin tregua, los colombianos son espectadores o víctimas de atracos callejeros y de discriminación racial, sexual y socioeconómica. Sin quererlo, se convierten en agentes de agresiones en el transporte urbano, el hogar, la escuela y el trabajo. Colombia tiene las tasas de mortalidad por homicidio más altas del mundo. Independientemente de la enorme sobrecarga institucional que impone a los servicios de salud y medicina legal, la violencia constituye actualmente en Colombia el principal problema de salud pública. Para hacerle frente, el sector de la salud debe elaborar políticas y financiar acciones; crear nuevos procesos de formación de personal, poner en marcha procesos de educación pública, y dedicar mayor esfuerzo y creatividad al campo de la investigación, que hasta ahora ha dado respuestas importantes pero aún insuficientes. Al reflexionar sobre la violencia, que es la sustitución de toda argumentación por la fuerza, es necesario ubicarla en el contexto de la vida y la salud. No se pretende solo racionalizarla, y menos aún sustituir la acción por la palabra o por las reflexiones, sino tratar de comprenderla a fondo con el objeto de buscarle alternativas. En el presente artículo se analiza, con esta finalidad, el tema de la violencia en Colombia, principalmente desde el punto de vista de su efecto en la salud de los colombianos y de sus implicaciones para el sector sanitario. El autor expone sus puntos de vista con plena conciencia de su subjetividad y limitaciones.

A sex pheromone receptor in the Hessian fly Mayetiola destructor (Diptera, Cecidomyiidae

Directory of Open Access Journals (Sweden)

Martin N. Andersson

2016-09-01

Full Text Available The Hessian fly, Mayetiola destructor Say (Diptera, Cecidomyiidae, is a pest of wheat and belongs to a group of gall-inducing herbivores. This species has a unique life history and several ecological features that differentiate it from other Diptera such as Drosophila melanogaster and blood-feeding mosquitoes. These features include a short, non-feeding adult life stage (1-2 days and the use of a long-range sex pheromone produced and released by adult females. Sex pheromones are detected by members of the odorant receptor (OR family within the Lepidoptera, but no receptors for similar long-range sex pheromones have been characterized from the Diptera. Previously, 122 OR genes have been annotated from the Hessian fly genome, with many of them showing sex-biased expression in the antennae. Here we have expressed, in HEK293 cells, five MdesORs that display male-biased expression in antennae, and we have identified MdesOR115 as a Hessian fly sex pheromone receptor. MdesOR115 responds primarily to the sex pheromone component (2S,8E,10E-8,10-tridecadien-2-yl acetate, and secondarily to the corresponding Z,E-isomer. Certain sensory neuron membrane proteins (i.e., SNMP1 are important for responses of pheromone receptors in flies and moths. The Hessian fly genome is unusual in that it encodes six SNMP1 paralogues, of which five are expressed in antennae. We co-expressed each of the five antennal SNMP1 paralogues together with each of the five candidate sex pheromone receptors from the Hessian fly and found that they do not influence the response of MdesOR115, nor do they confer responsiveness in any of the non-responsive ORs to any of the sex pheromone components identified to date in the Hessian fly. Using Western blots, we detected protein expression of MdesOrco, all MdesSNMPs, and all MdesORs except for MdesOR113, potentially explaining the lack of response from this OR. In conclusion, we report the first functional characterization of an OR from the

Permethrin resistance in Aedes albopictus (Diptera: Culicidae) and associated fitness costs.

Science.gov (United States)

Chan, Hiang Hao; Zairi, Jaal

2013-03-01

Insecticide resistance has become a serious issue in vector management programs. Information on insecticidal resistance and its associated mechanisms is important for successful insecticide resistance management. The selection of a colony of permethrin-resistant Aedes albopictus (Skuse) (Diptera: Culicidae), originating from Penang Island, Malaysia, yielded high larval-specific resistance to permethrin and cross-resistance to deltamethrin. Synergism assays showed that the major mechanism underlying this resistance involves cytochrome P450 monooxygenase. The resistance is autosomal, polygenically inherited and incompletely dominant (D = 0.26). Resistant larvae were reared under different conditions to assess the fitness costs. Under high larval density, larval development time of the resistant SGI strain was significantly longer than the susceptible VCRU strain. In both high- and low-density conditions SGI showed a lower rate of emergence and survival compared with the VCRU strain. Resistant larvae were more susceptible to predation by Toxorhynchites splendens (Wiedemann) (Diptera: Culicidae) larvae. The body size of SGI females reared under high-density conditions was larger compared with females of the susceptible strain. SGI females survived longer when starved than did VCRU females. The energy reserve upon eclosion was positively correlated with the size of the adults.

Full Text Available The terrorist violence in Colombia was preceded by political violence between Liberals and Conservatives, although we can not argue that the second is responsible for the appearance of the first, however, the accommodation of forces at the beginning of the Cold War took epicenter Latin America and thereby to Colombia. The regions of the country were suddenly pregnant by guerrilla groups praised by the USSR and blood filled the Colombian countryside. Colombian regions saw the birth of the new form of violence that would end up mutating into terrorism. Tolima Colombia-center platform would be the territorial conflict that began engulfing areas and finish an entire country. Only after 2002 it would begin to see the decline of modern terrorism.

Passage of ingested Mansonella ozzardi (Spirurida: Onchocercidae) microfilariae through the midgut of Aedes aegypti (Diptera: Culicidae).

When virus and microfilariae are ingested concurrently by a mosquito, microfilariae (mf) may penetrate the mosquito midgut and introduce virus directly into the mosquito hemocoel, allowing mosquitoes to become infectious much sooner than normal and enhancing transmission of viruses by mosquitoes. Mansonella ozzardi (Manson) is a benign filarial nematode parasite of humans in Latin America and is transmitted by black flies (Diptera: Simuliidae) and biting midges (Diptera: Ceratopogonidae). Because M. ozzardi and dengue are sympatric, we wanted to know whether M. ozzardi mf had the ability to penetrate the midgut of Aedes aegypti (L.) (Diptera: Culicidae) and thus play a potential role in the enhancement of dengue transmission. To test this, the F1 progeny from locally collected Ae. aegypti were fed on M. ozzardi-infected human males in an endemic village in northern Trinidad. Mosquitoes were dissected at various times after feeding and examined for mf in the midguts and thoraces. Microfilariae penetrated the midguts of 43% of 63 mosquitoes that ingested mf. Overall, 11% of mf penetrated the midgut by 17 h after being ingested. The intensity of midgut penetration was positively correlated to the numbers of mf ingested. Because midgut penetration is a key requirement for mf enhancement to occur, the potential exists that M. ozzardi could be involved in the enhancement of dengue virus transmission.

How do national-level actions overlap with global priorities for conservation? Answering this question is especially important in countries with high and unique biological diversity like Colombia. Global biodiversity schemes provide conservation guidance at a large scale, while national governments gazette land for protection based on a combination of criteria at regional or local scales. Information on how a protected area network represents global and national conservation priorities is crucial for finding gaps in coverage and for future expansion of the system. We evaluated the agreement of Colombia's protected area network with global conservation priorities, and the extent to which the network reflects the country's biomes, species richness, and common environmental and physical conditions. We used this information to identify priority biomes for conservation. We find the dominant strategy in Colombia has been a proactive one, allocating the highest proportion of protected land on intact, difficult to access and species rich areas like the Amazon. Threatened and unique areas are disproportionately absent from Colombia's protected lands. We highlight six biomes in Colombia as conservation priorities that should be considered in any future expansion of Colombia's protected area network. Two of these biomes have less than 3% of their area protected and more than 70% of their area transformed for human use. One has less than 3% protected and high numbers of threatened vertebrates. Three biomes fall in both categories. Expansion of Colombia's Protected Area Network should consider the current representativeness of the network. We indicate six priority biomes that can contribute to improving the representation of threatened species and biomes in Colombia.

Malaria mortality in Colombia, 1979-2008 Mortalidad por paludismo en Colombia, 1979-2008

Full Text Available

Introduction. In Colombia, malaria represents a serious public health problem. It is estimated that approximately 60% of the population is at risk of the disease.
Objective. To describe the mortality trends for malaria in Colombia, from 1979 to 2008.
Materials and methods. A descriptive study to determine the trends of the malaria mortality was carried out. The information sources used were databases of registered deaths and population projections from 1979 to 2008 of the National Statistics Department. The indicator used was the mortality rate. The trend was analyzed by join point regression.
Results. Six thousands nine hundred and sixty five deaths caused by malaria were certified for an age-adjusted rate of 0.74 deaths/100.000 inhabitants for the study period. In 74.3% of the deaths, the parasite species was not mentioned. The trend in the mortality rate showed a statistically significant decreasing behavior, which was lower from the second half of the nineties as compared with that presented in the eighties.
Conclusions. The magnitude of mortality by malaria in Colombia is not high, in spite of the evident underreporting. A marked downward trend was observed between 1979 and 2008. The information obtained from death certificates, along with that of the public health surveillance system will allow to modify the recommendations and improve the implementation of preventive and control measures to further reduce the mortality caused by malaria.

The contributions of Robineau-Desvoidy, Townsend, Villeneuve, Mesnil, Herting, Wood and many others are discussed within a chronological, taxonomic, and geographic context. The gradual development of the Tachinidae into its modern concept as a family of the Oestroidea and the emergence of the classificatory scheme of tribes and subfamilies in use today are reviewed. Certain taxa that have in the past been difficult to place, or continue to be of uncertain affinity, are considered and some are given in a table to show their varied historical treatments. The more significant systematic works published on the Tachinidae in recent decades are enumerated chronologically.

Carolina Lenis

2009-12-01

Full Text Available Ochetosoma heterocoelium Travassos, 1921 is a parasite that has been identified in snakes from different locations in Colombia and is considered of veterinary importance. Here, we present a redescription based on morphological traits of juveniles and adults. Parasite burden of O. heterocoelium in the host varied between 3-207 individuals which were localized in the oral cavity of snakes, causing damage that range from small infections to mechanical obstruction of the esophagus and Jacobson's organ. The low levels of abundance and prevalence in the snakes Leptodeira septentrionalis, Bothriechis schlegelli, Bothrops asper and Porthidium nasutum coming from the localities of Maceo, Vegachí and Acandí regions, suggest that the parasite is not a threat to the snakes of Colombia. We propose a treatment program that consists of manual removal of Digenea as well as treating snakes with antihelminthics, the applaying of soft antiseptics and monitoring recovery. The prevalence of O. heterocoelium was established in new regions, namely Middle Magdalena, Valle de Aburrá, Urabá Chocoano and northern Colombia. This extends the known geographical distribution from Brazil and Venezuela. New hosts were also identified: Atractus lasallei, Bothriechis schlegelli, Bothrops asper, Chironius carinatus, Leptodeira septentrionalis, Leptophis ahaetulla and Porthidium nasutum.Se identifica Ochetosoma heterocoelium Travassos, 1921 como un parásito de importancia veterinaria en ofidios de diferentes localidades de Colombia y se redescribe con base en las características morfológicas de individuos juveniles y adultos.

Homicide is a universal indicator of social violence with large public health consequences. To describe mortality by homicides and to analyze its trends and geographic distribution in Colombia between 1998 and 2012. We conducted a descriptive study of deaths by homicide in Colombia between 1998 and 2012 using official mortality databases and the population projections of the Departamento Administrativo Nacional de Estadística, DANE. We calculated age- and sex-specific mortality rates, and we analyzed the geographical distribution of mean-adjusted homicide mortality rates at municipal level. Between 1998 and 2012, 331,470 homicides were reported in Colombia. The mean crude rate was 51.5 per 100,000 inhabitants: 95.9 in men and 8.2 in women. Since 2003, a decrease in the number of deaths and rates was observed; 91.9% of the victims were men and the highest mortality rates were reported in the 20-29 years old group. The most frequently involved mechanism was the firearm: Eight of 10 homicides in men, and seven of 10 homicides in women. Out of 1,122 municipalities, 186 were in the highest quintile, accumulating 50.1% of all deaths. In Colombia, homicides have been one of the leading causes of death with a trend towards reduction since 2002. Its geographical distribution has been heterogeneous. To continue addressing this public health issue we must recur to multidisciplinary analytical methodologies for a better understanding of the phenomenon.

Se identificaron doce aislamientos provenientes de ocho plantas de especies diferentes de orquídeas. Tanto búsquedas BLAST del GenBank como el número de núcleos los agruparon en el género Ceratobasidium. Los resultados sugieren que este género se asocia con una amplia diversidad de orquídeas de há bitats variados en Colombia, además que para esta planta puede ser un importante hongo micorrízico. Sin embargo, surgen preguntas relacionadas con la patogenicidad de los Ceratobasidium micorrízicos sobre otros hospederos y su posible potencial biocontrolador de hongos patógenos en plantas cultivadas como arroz.Orchids require a mycorrhizal relationship for seed germination.

First records of Synthesiomyia nudiseta (Diptera: Muscidae) from forensic cases in Italy.

2017-07-01

The knowledge of the fauna associated with carrions and cadavers for a specific region plays a fundamental role in the estimation of the time since death in forensic cases. In the last years global warming and globalization have affected the insect species distribution. This phenomenon is affecting also the species of forensic interest associated with the cadaver decomposition. The species distribution shift, in the forensic context, has been mainly observed in Diptera of different family: Calliphoridae, Stratiomyidae and Phoridae. In the last decade the presence of the carrion feeding species, Synthesiomyia nudiseta (Diptera: Muscidae), was reported from forensic cases in Spain and in the last year from Italy where the species was collected from 5 bodies in different decomposition stages in the Genoa district. All the records concern indoor cases with the presence of other species belonging to the first colonization waves (e.g. Calliphoridae, Sarcophagidae). Different hypothesis about the presence of the species in Italy can be suggested, but the molecular analysis and the importation records support the introduction trough commercial exchanges with Asian countries instead of a variation in the species distribution area from the Iberian Peninsula.

Full Text Available La incriminación de especies de Lutzomyia del grupo verrucarum Theodor, 1965, en la transmisión de leishmaniosis en Colombia ha puesto de manifiesto la necesidad de conocer en detalle su distribución geográfica. Este trabajo pretende contribuir a su conocimiento mediante la incorporación de 34 registros nuevos, entre los que sobresalen el hallazgo de Lutzomyia spinicrassa en un bosque seco tropical de la Costa Atlántica, la presencia de Lutzomyia ovallesi en la Orinoquia y Amazonia y la simpatría de L. spinicrassa y Lutzomyia quasitownsendi en la Cordillera Oriental. Complementariamente, este artículo recopila y sintetiza la distribución municipal y altitudinal de las 19 especies registradas en el país. Los datos compilados muestran que la serie townsendi (L. spinicrassa, Lutzomyia longiflocosa, L. quasitownsendi, Lutzomyia sauroida, Lutzomyia torvida, Lutzomyia townsendi, Lutzomyia youngi está generalmente asociada con los pisos altitudinales premontano y montano bajo, mientras la serie verrucarum hace presencia desde el piso tropical hasta el montano con taxones de extenso ámbito geográfico (Lutzomyia evansi, Lutzomyia columbiana, L. ovallesi, Lutzomyia nuneztovari, Lutzomyia nevesi y taxones de distribución endémica (Lutzomyia andina, Lutzomyia disiuncta, Lutzomyia moralesi, Lutzomyia antioquiensis. De otro lado, los representantes de la serie pia (Lutzomyia pia, Lutzomyia limafalcaoae y de la serie serrana (Lutzomyia serrana aparecen desde el piso tropical hasta el montano bajo. Se postula que las divergencias en los rangos altitudinales podrían estar relacionadas intrínsecamente con el origen de las especies, derivándose de fenómenos climáticos y geológicos que han afectado la flora y fauna de la región andina.

Morphology of the larvae, male genitalia and DNA sequences of Anopheles (Kerteszia pholidotus (Diptera: Culicidae from Colombia

Jesús Eduardo Escovar

2014-07-01

Full Text Available Since 1984, Anopheles (Kerteszia lepidotus has been considered a mosquito species that is involved in the transmission of malaria in Colombia, after having been incriminated as such with epidemiological evidence from a malaria outbreak in Cunday-Villarrica, Tolima. Subsequent morphological analyses of females captured in the same place and at the time of the outbreak showed that the species responsible for the transmission was not An. lepidotus, but rather Anopheles pholidotus. However, the associated morphological stages and DNA sequences of An. pholidotus from the foci of Cunday-Villarrica had not been analysed. Using samples that were caught recently from the outbreak region, the purpose of this study was to provide updated and additional information by analysing the morphology of female mosquitoes, the genitalia of male mosquitoes and fourth instar larvae of An. pholidotus, which was confirmed with DNA sequences of cytochrome oxidase I and rDNA internal transcribed spacer. A total of 1,596 adult females were collected in addition to 37 larval collections in bromeliads. Furthermore, 141 adult females, which were captured from the same area in the years 1981-1982, were analysed morphologically. Ninety-five DNA sequences were analysed for this study. Morphological and molecular analyses showed that the species present in this region corresponds to An. pholidotus. Given the absence of An. lepidotus, even in recent years, we consider that the species of mosquitoes that was previously incriminated as the malaria vector during the outbreak was indeed An. pholidotus, thus ending the controversy.

Between 1998 and 2000, the occurrence of 8 cases of American visceral leishmaniasis in children from a recently established human settlement in Guatiguará, in the municipality of Piedecuesta (Santander, Colombia) indicated the possible presence of Leishmania transmission in this locality. This observation motivated the current entomological investigation. To determine the relative frequency of Lutzomyia longipalpis inside houses and outdoors, and the natural infection of this vector with Leishmania spp. CDC light traps were used for sampling inside houses and outdoors, and sand flies were collected on human volunteers and domestic animals, and in resting places, during the period from May 1999 through September 2000. Natural infection was determined by PCR, in pools of female Lutzomyia longipalpis. A total of 7,391 phlebotomine sand flies were collected. The predominant species was Lutzomyia longipalpis (Lutz & Neiva), representing 99.5% of captures. In the sand flies collected with CDC light traps, L. longipalpis was more frequently collected indoors than outdoors (p = 0.0001). The total rate of natural infection was 1.93% and a positive correlation was observed between months with higher abundance and the number of infected females entering human dwellings. The results indicate that in Guatiguará Lutzomyia longipalpis, shows marked tendency for the indoors, which has important implications for leishmaniasis transmission. Furthermore, transmission risk is increased during the months of higher abundance due to the entry of a higher number of infected females. From the standpoint of control, this behaviour permits the design of strategies to reduce indoor transmission.

Evaluation of methodologies for remunerating wind power's reliability in Colombia

International Nuclear Information System (INIS)

Botero B, Sergio; Isaza C, Felipe; Valencia, Adriana

2010-01-01

Colombia strives to have enough firm capacity available to meet unexpected power shortages and peak demand; this is clear from mechanisms currently in place that provide monetary incentives (in the order of nearly US$ 14/MW h) to power producers that can guarantee electricity provision during scarcity periods. Yet, wind power in Colombia is not able to currently guarantee firm power because an accepted methodology to calculate its potential firm capacity does not exist. In this paper we argue that developing such methodology would provide an incentive to potential investors to enter into this low carbon technology. This paper analyzes three methodologies currently used in energy markets around the world to calculate firm wind energy capacity: PJM, NYISO, and Spain. These methodologies are initially selected due to their ability to accommodate to the Colombian energy regulations. The objective of this work is to determine which of these methodologies makes most sense from an investor's perspective, to ultimately shed light into developing a methodology to be used in Colombia. To this end, the authors developed a methodology consisting on the elaboration of a wind model using the Monte-Carlo simulation, based on known wind behaviour statistics of a region with adequate wind potential in Colombia. The simulation gives back random generation data, representing the resource's inherent variability and simulating the historical data required to evaluate the mentioned methodologies, thus achieving the technology's theoretical generation data. The document concludes that the evaluated methodologies are easy to implement and that these do not require historical data (important for Colombia, where there is almost no historical wind power data). It is also found that the Spanish methodology provides a higher Capacity Value (and therefore a higher return to investors). The financial assessment results show that it is crucial that these types of incentives exist to make viable

Hepatozoonosis is a tick-borne disease whose transmission to dogs occurs by ingestion of oocysts infected ticks or feeding on preys infested by infected ticks. Until now, there is no previous report of molecular characterization of Hepatozoon sp. in dogs from Colombia. EDTA blood samples were collected from 91 dogs from central-western region of Colombia (Bogotá, Bucaramanga, and Villavicencio cities) and submitted to 18S rRNA Hepatozoon sp. PCR and blood smears confection. Phylogenetic analysis was used to access the identity of Hepatozoon species found in sampled dogs. From 91 sampled dogs, 29 (31.8%) were positive to Hepatozoon sp. (25 dogs were only positive in PCR, 1 was positive only in blood smears, and 3 were positive in both blood smears and PCR). After sequencing, the found Hepatozoon sp. DNA showed 100% of identity with Hepatozoon canis DNA isolates. The phylogenetic tree supported the identity of the found Hepatozoon sp. DNA, showing that the isolates from Colombia were placed in the same clade than other H. canis isolates from Venezuela, Spain, and Taiwan. This is the first molecular detection of H. canis in dogs from Colombia.

Full Text Available In Colombia, no systematic work have been carried out to determine the demand for fruits beyond descriptive analysis of per capita consumption according to different individual socioeconomic characteristics and much less for a specific product such as guava, Psidium guajava L. (Myrtaceae. This paper estimates the relationship between guava prices and the demand of guava in Colombia. We found that guava consumption is not affected by its price and its demand is highly correlated to income. While socio-economic characteristics such as income, education and household head labor affect the decision-making for consuming guava, other characteristics such as race and the number of household members determine the quantity of guava consumed in a Colombian household.

Abstract The prevalence of Prediabetes in Colombia is high, and despite being recognized and categorized in the main Medical Guidelines and included in the International Classification of Diseases in Colombia, knowledge and awareness of it is limited amongst healthcare professionals and in the community. Our expert group recommends that educational programs emphasize a global approach to risk which includes a recognition of the importance of prediabetes and its evaluation along with and other risk factors such as a family history of DM2, overweight and obesity, dislipidemia and hypertension. Studies conducted in Colombia demonstrate the value of the FINDRIS questionnaire as a tool to identify subjects at risk of prediabetes and DM2, and we recommend that it should be systematic applied throughout the country as part of government policy. Prediabetes progresses to DM2 at an annual rate of 10%, but it has also been shown that prediabetes is an independent risk factor for cardiovascular outcomes. On this basis, the Committee recommends that once prediabetes is detected and diagnosed, immediate management of the disease begins through lifestyle changes, with follow up assessments performed at 3 and 6 months. If the patient does not respond with a weight loss of at least 5% and if the HbA1C values ​​are not normalized, pharmacological management should be initiated with a metformin dose of 500 mg / day, increasing up to 1,500 - 1,700 mg / day, according to tolerance.

Dengue in Colombia is an important public health problem due to the huge economic and social costs it has caused, especially during the disease outbreaks.  To describe the behavior of dengue mortality in Colombia between 1985 and 2012.  We conducted a descriptive study. Information was obtained from mortality and population projection databases provided by the Departamento Administrativo Nacional de Estadística (DANE) for the 1985-2012 period. Mortality rates, rate ratios, and case fatality rates were estimated.  A total of 1,990 dengue deaths were registered during this period in Colombia. Dengue mortality rates presented an increasing trend with statistical significance between 1985 and 1998. Higher mortality rates were reported in men both younger than 5 years and older than 65 years. Between 1995 and 2012, category 1 to 4 municipalities reported the highest mortality rates. Case fatality rates varied during the period between 0.01% and 0.39%.  Dengue is an avoidable disease that should disappear from mortality statistics as a cause of death. The event is avoidable if the proposed activities from the Estrategia de Gestión Integrada (EGI)-Dengue are implemented and evaluated. We recommend encouraging the development of an informational culture to contribute to decision making and prioritizing resource allocation.

Estimate price and income elasticities of aggregate demand for cigarettes in Colombia, by controlling for structural market changes since the late 1990s, to identify policy opportunities for taxes that could improve public health and increase tax revenues. Measurement of aggregate demand for cigarettes using gross income reported on value-added tax returns submitted to Colombia's National Tax and Customs Office (DIAN is the acronym in Spanish) by the tobacco product manufacturing industry, subtracting exports. A quarterly time series was obtained for the period 1994-2014. The econometric estimation using two-stage least squares controls for price endogeneity and uses a set of dummy variables to control for structural changes in the market and in its regulation. Demand is, from a statistical standpoint, sensitive to price and to income. Price elasticity of demand is -0.78 and income elasticity is 0.61. Inelastic demand implies that it is possible, through cigarette excise taxes, to meet public health targets and increase revenues simultaneously. The results also suggest that the considerable increase in household income in Colombia in the first decade of the 21st century increased purchasing power, which, lacking an accompanying tax increase, promoted cigarette consumption, with negative effects on public health, and wasted an opportunity to increase tax revenues.

Malaria is a serious health problem in Córdoba and Antioquia states in northwestern Colombia, where 64.4% of the total Colombian cases were reported in 2007. Because little entomological information is available in this region, the aim of this work was to identify the Anopheles species composition and natural infectivity of mosquitoes distributed in seven localities with the highest malaria transmission. A total of 1,768 Anopheles mosquitoes were collected using human landing catches from March 2007 to July 2008. Ten species were identified; overall, An. nuneztovari s.l. was the most widespread (62%) and showed the highest average human biting rates. There were six other species of the Nyssorhynchus subgenus: An. albimanus (11.6%), An. darlingi (9.8%), An. braziliensis (6.6%), An. triannulatus s.l. (3.5%), An. albitarsis s.l. and An. oswaldoi s.l. at <1%; and three of the Anopheles subgenus: An. punctimacula, An. pseudopunctipennis s.l. and An. neomaculipalpus at <1% each. Two species from Córdoba, An. nuneztovari and An. darlingi, were detected naturally infected by Plasmodium vivax VK247 using ELISA and confirmed by nested PCR. All species were active indoors and outdoors. These results provide basic information for targeted vector control strategies in these localities. PMID:20140372

Full Text Available Colombia is a country with a negative historical positioning in international markets. Despite efforts by governments and influencers to improve its image, the perception of foreigners remains polarized, being associated with coffee and drug trafficking. This article is the result of a qualitative research conducted on foreign visitors from eight countries in the Americas with the largest number of visitors to Colombia in 2013: The United States, Venezuela, Ecuador, Argentina, Peru, Brazil, Mexico and Chile. The study found that the image of Colombia is not one-dimensional, but multidimensional. It identifies five dimensions that influence country image: knowledge of the country, the industrial orientation, visitor attitudes, perceptions of prospects and preferences and finally interests associated with its image.Colombia es un país con un posicionamiento histórico negativo en mercados internacionales.

Alonso, David L; Latorre, Sergio; Castillo, Elianna; Brandão, Pedro F B

2014-03-01

The international literature on the presence of arsenic (As) in Latin America does not disclose the true magnitude of the presence of As in Colombia. In this paper, we summarize the literature on As occurrence in Colombia. The data reveal that As is present in matrices such as soil, sediments and water and in the food chain. Some of the As concentrations exceed the limits specified by national and international regulations. Arsenic higher concentrations are associated with mining regions (e.g., soils, up to 148 mg/kg; sediments, up to 1400 mg/kg) and agricultural areas (e.g., vegetables, up to 5.40 mg/kg; irrigation water, up to 255 μg/L), and underscore the potential human and environmental risks associated with the presence of As in the country. This review highlights the importance of focusing research on understanding the occurrence, origin and distribution of As in Colombia to better understand its environmental and public health impact.

Full Text Available The diptera grouped in the family Cecidomyiidae, are considered important pests in the crop of mango (Mangifera indica L.. In the period of 2013-15, prospections were carried out in patios and plantations of several localities of Cuba (Havana, Artemisa, Mayabeque, Ciego de Ávila and Santiago de Cuba, during the stages of vegetative and floral sprouting, to evaluate the presence of insects. Thirteen samplings were made and 25 young leaves and 10 floral shoots were collected per sample, for a total of 325 young leaves and 130 floral shoots in which the number of galls, larvae, pupae and adults of an agallero insect was determined. A total of 2 423 galls were found in young leaves, which represented an average of 7.5 guts per leaf. A total of 207 larvae, 60 pupae and 40 adults were counted among diptera males and females. The morphological characters of the collected insects allowed identifying Procontarinia mangiferae (Felt, belonging to the family Cecidomyiidae, as the cause of the galls in the young leaves and floral shoots in the mango areas sampled.

The integration of the sterile insect technique (SIT) in the management of the South American fruit fly Anastrepha fraterculus (Wiedemann) (Diptera: Tephritidae) is a promising alternative to chemically-based control in those areas where it is sympatric with Ceratitis capitata (Wiedemann) (Diptera: Tephritidae) or other tephritid species for which the SIT is being used. Implementation of the SIT requires the development of a cost effective mass-rearing protocol. In this work, we present demographic and quality control parameters for the A. fraterculus strain reared at the Estacion Experimental Agroindustrial Obispo Colombres, Tucuman, Argentina. Considering the rearing cage as the reproduction unit, we observed that fecundity is optimal during the first 3 weeks after the onset of oviposition. Fertility was constant during this period. During 2003 and 2004, some improvements were made to the existing rearing protocol, which resulted in increased larval viability, pupal weight, and adult emergence. Current weekly egg production is 1 million per week. These eggs are used to maintain the colony and to assess quality parameters. Finally, research needs leading to improved yields and fly quality are discussed. (author) [es

From June to October 2003 studies related to environmental and ecological aspects of fishes and macro-invertebrates in three sampling stations of Tutunendo River located in the Department of Choco, Colombia, were carried out. Abiotic factors like conductivity, pH, oxygen and temperature were also measured. Eighty one hundred fish specimens, belonging to three orders, seven families and twelve species were collected. The order Siluriformes presented the greatest abundance (70.72%) with three families, seven species and 128 specimens, followed by Characiformes with three families, three species and 43 specimens (23.53%). At the same time 1.211 aquatic macro-invertebrates were collected represented by the orders Ephemeroptera (50.28%), Odonata (11.40%), Coleoptera (8.67%), Hemiptera (8.42%), Trichoptera (7.30%), Plecoptera (5.7%), Megaloptera (3.3%), Lepidoptera (2.31%), Diptera (0.37%) and Haplotaxida (0.08%). The families Leptophlebiidae (37.24%), followed by Naucoridae (8.42%) and Baetidae (8%) were the most represented. Relationship between fishes and macro invertebrates as food items in Geophagus pellegrini and Astyanaxfasciatus were also studied. G. pellegrini was zooplanctophage with preference for Baetidae, Leptohyphidae, Hydrobiosidae, Leptoceridae and Naucoridae. Finally, the present work indicated that Tutunendo town does not have potential fishery; the economy is supported in productive traditional systems based in the agriculture, complemented with fishery and extractive activities

Energetic Planning in Colombia

In the country one of the most dynamic sectors in the last years, it has been the mining - energy sector that has had rates of increase superiors to 5%. The most critical situation corresponds to the sector of hydrocarbons, where the exploration in Colombia has arrived at its lower historical levels as they are those of 22 and 30 perforated wells, and 2148 and 2300 acquired kilometers of seismic 2d, in the years of 1996 and 1997, that which doesn't agree with the National Energy Plan NEP that inclined to perforate 100 exploratory wells per year, for the period 1997 - 2010, with the purpose of maintaining the production of 1.0 mbd starting from the year 2000 and this way to avoid that Colombia loses its self-sufficiency and be importer in the 2004 again. The oil politics in charge of the Ecopetrol, will have to be revised with different approaches if one wants a reactivation, because from 1989, year in that included the escalation clause, not alone it has not been possible to increase the exploration, but rather it has fallen at the mentioned levels. In the electric sector; the Regulation of Energy and Gas Commission - REGC, has been a supremely difficult to put priorities, because measures and immediate and urgent changes are needed. To medium term, Colombia should solve its institutional, normative problems and of infrastructure, to be able to have a true integral planning, that takes us to receive the next millennium with true energy self-sufficiency and a consolidation of the country in the export of coal and petroleum, if they take the necessary measures and avoid the lost of the self-sufficiency in hydrocarbons

Full Text Available Necrophagous Diptera associated with wild animal carcasses in southern Brazil. The aim of this study was to acquire a better knowledge concerning the diversity of necrophagous Diptera that develop on wild animal carcasses. For this purpose, the decomposition of six wild animal carcasses was observed in order to collect and identify the main species of necrophagous flies associated with the decomposition process. The carcasses were found on highways near the cities of Pelotas and Capão do Leão in the initial stage of decomposition, with no significant injuries or prior larval activity. Four wild animal models were represented in this study: two specimens of Didelphis albiventris Lund, 1840; two Tupinambis merianae Linnaeus, 1758; one Nothura maculosa Temminck, 1815; and one Cerdocyon thous Linnaeus, 1766. A total of 16,242 flies from 14 species were reared in the laboratory, where Muscidae presented the greatest diversity of necrophagous species. Overall, (i carcasses with larger biomass developed a higher abundance of flies and (ii the necrophagous community was dominated by Calliphoridae, two patterns that were predicted from published literature; and (iii the highest diversity was observed on the smaller carcasses exposed to the lowest temperatures, a pattern that may have been caused by the absence of the generalist predator Chrysomya albiceps (Wiedemann, 1819. (iv An UPGMA analysis revealed a similar pattern of clusters of fly communities, where the same species were structuring the groupings.

Full Text Available Flies (Diptera, blow flies, house flies, flesh flies, horse flies, cattle flies, deer flies, midges and mosquitoes are among the four megadiverse insect orders. Several species quickly colonize human cadavers and are potentially useful in forensic studies. One of the major problems with carrion fly identification is the lack of taxonomists or available keys that can identify even the most common species sometimes resulting in erroneous identification. Here we present a key to the adults of 12 families of Diptera whose species are found on carrion, including human corpses. Also, a summary for the most common families of forensic importance in South America, along with a key to the most common species of Calliphoridae, Muscidae, and Fanniidae and to the genera of Sarcophagidae are provided. Drawings of the most important characters for identification are also included.Diptera (califorídeos, sarcofagídeos, motucas, moscas comuns e mosquitos é a uma das quatro ordens megadiversas de insetos.

Violence and health in Colombia

Saúl Franco Agudelo

1997-09-01

Full Text Available In Colombia, violence seems uncontrollable. Along with massacres and group killings of astonishing cruelty, there are also kidnappings and disappearances, abuse of children and the elderly, and rape of young adolescents. Every day, without respite, Colombians are witnesses or victims of street crimes as well as racial, sexual, and socioeconomic discrimination. Unwillingly, they become agents of aggression in public transport, at home, at school, and at work. Colombia has the highest rates of mortality from homicide in the world. Apart from the enormous institutional burden that violence imposes on the health services and forensic medicine, it now constitutes the principal public health problem in the country. To confront it, the health sector must develop policies and finance actions, develop innovative ways to train personnel, implement public education processes, and devote more effort and greater creativity to research, which up to now has provided some important, albeit insufficient, responses. Violence, which is the substitution of force for any type of dialogue, must be considered within the context of life and health. Doing so is not an attempt to rationalize violence, much less to substitute words or reflection for action, but rather an attempt to understand it in depth in order to search for alternatives. With that goal, this article analyzes the subject of violence in Colombia, principally from the perspective of its effect on the health of the citizens and its implications for the health sector. The author fully recognizes the subjectivity and limitations of the views he expresses herein.

Culicoides pachymerus is a major pest species for the inhabitants of the western Boyacá province of Colombia. The effect of a repellent lotion based on p-menthane-3,8-diol (16%) and lemongrass oil (2%) was evaluated against the bites of C. pachymerus. The repellent lotion was compared simultaneously with a control (no treatment) by human landing catches of C. pachymerus on the forearms of paired volunteers situated near human dwellings. Protection percentage and protection time for 3 to 6 h after repellent application was calculated. The test was repeated ten times. Only two females of C. pachymerus were collected on arms with the repellent treatment. In contrast, the mean biting rate in the untreated control was 47.7 midges/person/10 min. Mean protection percentage of the repellent was 100% up to 4 h and 99.5% up to 5 h. Protection time was 332.2 and 338.2 min in the two replicates where bites of C. pachymerus were confirmed. In the remaining eight replicates protection time exceeded the test duration. The repellent showed high efficacy against C. pachymerus, up to 5 h post-application.

Full Text Available Aedes aegypti is the primary vector of the four serotypes of dengue virus (DENV1-4, Chikungunya and yellow fever virus to humans. Previous population genetic studies have revealed a particular genetic structure among the vector populations in the Americas that suggests differences in the ability to transmit DENV. In Colombia, despite its high epidemiologic importance, the genetic population structure and the phylogeographic depiction of Ae. aegypti, as well as its relationship with the epidemiologic landscapes in cities with heterogeneous incidence levels, remains unknown. We conducted a spatiotemporal analysis with the aim of determining the genetic structure and phylogeography of Colombian populations of Ae. aegypti among cities with different eco-epidemiologic characteristics with regard to DENV.Mitochondrial cytochrome oxidase C subunit 1 (COI--NADH dehydrogenase subunit 4 (ND4 genes were sequenced and analyzed from 341 adult mosquitoes collected during 2012 and 2013 in the Colombian cities of Bello, Riohacha and Villavicencio, which exhibit low, medium and high levels of incidence of DENV, respectively. The results demonstrated a low genetic differentiation over time and a high genetic structure between the cities due to changes in the frequency of two highly supported genetic groups. The phylogeographic analyses indicated that one group (associated with West African populations was found in all the cities throughout the sampling while the second group (associated with East African populations was found in all the samples from Bello and in only one sampling from Riohacha. Environmental factors such as the use of chemical insecticides showed a significant correlation with decreasing genetic diversity, indicating that environmental factors affect the population structure of Ae. aegypti across time and space in these cities.Our results suggest that two Ae. aegypti lineages are present in Colombia; one that is widespread and related to a West

Full Text Available Rickettsiosis: a deadly emerging and re-emerging disease in Colombia. Rickettsiosis was first described in Colombia in 1937 byDr Luis Patiño during an outbreak of a disease with unspecific signs. Rickettsia is a genus of Gram-negative intracellular obligatorybacteria having caused several epidemics around the world, and are transmitted mainly by ticks, fleas, lice and mites. The most fatalwithin this group of diseases is known as Rocky Mountain Spotted Fever (RMSF, which is caused by Rickettsia rickettsia. There is alsothe endemic typhus caused by Rickettsia typhi and epidemic typhus caused by Rickettsia prowazekii. In Colombia, several outbreaks ofRMSF have occurred during the last decade. The best known among those have hit the municipalities of Necoclí and Turbo, in Antioquiain 2006 and 2008 respectively, and Los Cordobas in the department of Cordoba in 2007. The goal of this review is to describe the state ofthe art of rickettsiosis, a forgotten lethal disease that has re-emerged in our country, and leave some questions as an inspiration for future research that will hopefully lead scientists to a better understanding of this entity potentially endemic in some areas of Colombia.

Lopez Martinez, Jessika; Velasquez Trujillo, Luz Elena

2012-01-01

Some species of Paramphistomidae (Trematoda: Digenea) that parasitize the digestive system of ruminants can cause decreases in milk and meat production. In Colombia, paramphistomosis cattle have been recorded from 1) dairy farms at high altitudes in the mountains of Antioquia (northwestern Colombia) where Cotylophoron cotylophorum was described as the causative agent; and 2) from lowland savannas in eastern Colombia, which has been attributed to several species of Paramphistomidae but with records remaining to be confirmed. Therefore, the discovery of digenea of cattle slaughtered in Guamal, Meta (eastern Colombia), was an opportunity to start with the description of the Paramphistomidae in this region. Between 2006 and 2008, we sampled 715 adult flukes from the rumen of 32 cattle from the departments of Meta and Guaviare. The morphological analysis shows that the adult has the following features typical of the family Paramphistomidae: Laurers canal crossing the excretory vesicle and opening posteriorly to the excretory pore; acetabulum small as in the genus Cotylophoron; pharynx as in Calicophoron; genital sucker without sphincter; absence of esophageal bulb and the lateral and dorsal vitellaria converging posteriorly in the body, below the acetabulum, as in C. panamensis. This study confirms the presence of paramfistomosis in Meta and it is the first report of Cotylophoron panamensis in cattle from the department of Guaviare, therefore expanding its geographic range in Colombia.

Ecological studies on the sand fly Lutzomyia longipalpis (Lutz & Neiva) were conducted during 1990-1993 at a small rural community in Colombia where American visceral leishmaniasis is endemic. Weekly sand fly collections were made from pigpens, houses, and natural resting sites, using hand-held aspirators, sticky (oiled) paper traps, and opossum-baited Disney traps. In total, 263,094 sand flies were collected; L. longipalpis predominated (86.1%), followed by L. trinidadensis (11.0%), L. cayennensis (2.7%), and 8 other Lutzomyia species. The species composition and sex ratio of these sand flies varied among sites and by collection method. L. longipalpis were captured most efficiently by direct aspiration from animal bait. Conversely, sticky paper traps, especially inside houses and at rock resting sites, collected a greater diversity of species, but a lower relative abundance of L. longipalpis.

La elaboración de indicadores de pobreza en Colombia ha sido objeto de varios estudios en el Departamento Nacional de Estadística, DANE, pero sólo ahora se intenta un análisis de la distribución de ingreso que explique las causas de la pobreza relativa. Con base en la información sobre la distribución del ingreso per cápita de las personas, según características socio demográficas, y a partir de la distribución de los ingresos laborales, se concluye que:  el mayor grado de desigualdad se observa en las categorías de ingresos de capital y ocasionales; los ingresos menos concentrados son los salarios y las transferencias;- la fuente principal de ingresos es la laboral; - la variable que mejor explica la distribución de ingresos de los ocupados es el nivel de educación y, por lo tanto, este es un elemento esencial de la movilidad social en Colombia; - y, por último, es significativa la dependencia entre los ingresos percibidos por los hombres y por las mujeres.

The number of speciesrecorded is 304, with Drosophila being the genus with the greatest number of species, followed by Zygothrica,Hirtodrosophila and Diathoneura, which belong to the Drosophilinae subfamily. Drosophila was shown to be the mostinvestigated taxon in the family, with the best resolved species distribution. The low number of records of species fromother genera indicates the paucity of studies specifically designed to investigate these species. Records of species forsome regions of the country like the north and northeast, as well as for some biomes like Caatinga, Pantanal and thePampas, are likewise rare.

2012-01-01

Mining environmental liabilities (PAM from its acronym in Spanish) are areas where there is a need for restoration, mitigation or compensation for environmental damage or unmanaged impact, produced by inactive or abandoned mining that threatens health, quality of life or public or private property. In Colombia the environmental liabilities from mining have not been regulated, but given the age and the prevalence of informality in mining, there is increasing interest in defining, regulating and managing these obligations. In this paper we approach the problem of valuing mining environmental liabilities by examining different management approaches for such liabilities around the world. We also identify key information requirements to manage mining environmental liabilities in Colombia.

Esa es una tarea difícil, ya que, por un lado, la población colombiana en la actualidad manifiesta una gran polarización respecto al tema, y por otro, la despenalización del aborto es objeto no solo del derecho sino también de diversas disciplinas científicas y filosóficas y de sistemas normativos como la ética, la moral y la religión. En este artículo se analiza, en primer lugar, lo que llevó a la Corte  onstitucional a pronunciarse sobre la despenalización del aborto en Colombia. En segundo lugar, se tratan las consideraciones de la Corte y el debate jurídico-ideológico que tuvo que librar para llegar a su decisión.

Full Text Available Marihuana consumption did not become widespread in Colombia as the simple result of its increased use as part of the north-American counterculture of the 1960s. Even though marihuana-growing spiraled to satisfy north-American demand at the end of the 1960s and 1970s there was an important market for domestic consumption in Colombia. "Exonerating-type" academic literature tending to see countries such as Colombia as the passive "victims" of externally-induced phenomena is thus questioned.

Full Text Available Los pasivos ambientales mineros (PAM se refieren a "un área donde existe la necesidad de restauración, mitigación o compensación por un daño ambiental o impacto no gestionado, producido por actividades mineras inactivas o abandonadas que pone en riesgo la salud, calidad de vida o bienes públicos o privados" . En Colombia no se han reglamentado los PAM, pero dada la antigüedad y la prevalencia de la informalidad en la explotación minera, el interés en definir, reglamentar y gestionar estas obligaciones es creciente. En este artículo nos aproximamos a la problemática de la valoración de pasivos ambientales en Colombia, basándonos en la revisión de la gestión de PAM mineros en el mundo e identificamos los requerimientos de información clave para realizar dicha gestión en Colombia.

Proteolytic activity regarding Sarconesiopsis magellanica (Diptera: Calliphoridae) larval excretions and secretions.

2013-12-01

Sarconesiopsis magellanica (Diptera: Calliphoridae) is a medically important necrophagous fly which is used for establishing the post-mortem interval. Diptera maggots release proteolytic enzymes contained in larval excretion and secretion (ES) products playing a key role in digestion. Special interest in proteolytic enzymes has also been aroused regarding understanding their role in wound healing since they degrade necrotic tissue during larval therapy. This study was thus aimed at identifying and characterising S. magellanica proteolytic enzyme ES products for the first time. These products were obtained from first-, second- and third-instar larvae taken from a previously-established colony. ES proteins were separated by SDS-PAGE and their proteolytic activity was characterised by zymograms and inhibition assays involving BAPNA (Nα-benzoyl-dl-Arg-p-nitroanilide) and SAPNA substrates, using synthetic inhibitors. The protein profile ranged from ∼69kDa to ∼23kDa; several of them coincided with the Lucilia sericata ES protein profile. Serine-protease hydrolysis activity (measured by zymogram) was confirmed when a ∼25kDa band disappeared upon ES incubation with PMSF inhibitor at pH 7.8. Analysis of larval ES proteolytic activity on BAPNA and SAPNA substrates (determined by using TLCK and TPCK specific inhibitors) suggested a greater amount of trypsin-like protease. These results support the need for further experiments aimed at validating S. magellanica use in larval therapy. Copyright © 2013 Elsevier B.V. All rights reserved.

Mental health service delivery following health system reform in Colombia.

Science.gov (United States)

Romero-González, Mauricio; González, Gerardo; Rosenheck, Robert A

2003-12-01

In 1993, Colombia underwent an ambitious and comprehensive process of health system reform based on managed competition and structured pluralism, but did not include coverage for mental health services. In this study, we sought to evaluate the impact of the reform on access to mental health services and whether there were changes in the pattern of mental health service delivery during the period after the reform. Changes in national economic indicators and in measures of mental health and non-mental health service delivery for the years 1987 and 1997 were compared. Data were obtained from the National Administrative Department of Statistics of Colombia (DANE), the Department of National Planning and Ministry of the Treasury of Colombia, and from national official reports of mental health and non-mental health service delivery from the Ministry of Health of Colombia for the same years. While population-adjusted access to mental health outpatient services declined by -2.7% (-11.2% among women and +5.8% among men), access to general medical outpatient services increased dramatically by 46%. In-patient admissions showed smaller differences, with a 7% increase in mental health admissions, as compared to 22.5% increase in general medical admissions. The health reform in Colombia imposed competition across all health institutions with the intention of encouraging efficiency and financial autonomy. However, the challenge of institutional survival appears to have fallen heavily on mental health care institutions that were also expected to participate in managed competition, but that were at a serious disadvantage because their services were excluded from the compulsory standardized package of health benefits. While the Colombian health care reform intended to close the gap between those who had and those who did not have access to health services, it appears to have failed to address access to specialized mental health services, although it does seem to have promoted a

Full Text Available El interés en los problemas que hoy llamamos psicológicos se encuentra en todas las grandes civilizaciones. En América existieron importantes ideas psicológicas en los Mayas, Aztecas, Incas y en los pobladores de la actual Colombia. La psicología en su conceptualización moderna comienza en 1879 con la fundación del primer Laboratorio de Psicología Experimental en la Universidad de Leipzig por obra de W. Wundt. Hoy la psicología como disciplina es tanto una ciencia como una profesión, y tanto una ciencia natural como una ciencia social. En el contexto colombiano el origen está ligado a la fundación del Instituto de Psicología Aplicada de la Universidad Nacional de Colombia, el 20 de noviembre de 1947, con el cual comienzan los estudios profesionales de psicología en Colombia y en el resto de Latinoamérica. En este artículo se analiza el estado de la psicología como disciplina, como campo de investigación y como área de aplicación profesional. Se concluye que es necesario enfatizar más los aspectos científicos, además de los profesionales y trabajar en contextos multi e interdisciplinarios, con otros profesionales de las ciencias naturales y sociales.

Subsamples of sand flies collected weekly from pigpens, the interior of houses, and natural outdoor resting sites were dissected to determine physiological age and Leishmania chagasi Cunha & Chagas infection rates. Eleven female L. longipalpis had flagellates in their gut, 2 of which were successfully cultured and identified as Leishmania chagasi. The reproductive status, stage of ovarian development, and trophic history of female sand flies varied among sites, habitats, and time of collection. The percentage of parous females ranged from about one-third to two-thirds overall and varied seasonally. Of most relevance to AVL transmission was the finding that 8% of L. longipalpis females were multiparous. In addition, our data suggest that L. longipalpis rest inside houses after blood-feeding outdoors, and that this species can blood-feed more than once during a single gonotrophic cycle.

Scuttle flies (Diptera: Phoridae) are small-sized insects of forensic importance. They are well known for diversified species and habitats, but in the context of forensic entomology, scuttle flies' inhabitance of corpses remains inadequately explored. With recent reports indicating the existence of more scuttle fly species possibly inhabiting these environments, a decomposition study using animal carcasses in enclosed environments was conducted. The aim was to record the occurrence of scuttle flies on rabbit carcasses placed in sealed plastic waste bins for a 40-day period. The study was conducted as two replicates in Bangi, Selangor. Sampling was carried out at different time intervals inside a modified mosquito net as a trap. Inside the trap, adult scuttle flies were aspirated and preserved in 70% ethanol. The fly larvae and pupae were reared until their adult stage to facilitate identification. From this study, six scuttle fly species were collected, i.e., Dahliphora sigmoides (Schmitz) ♂, Gymnoptera simplex (Brues) ♀ , Megaselia scalaris (Loew) ♂♀ , Puliciphora borinquenensis (Wheeler) ♂, Puliciphora obtecta Meijere ♀ and Spiniphora sp. ♀ . Both D. sigmoides and P. obtecta were newly recorded in Malaysia, whilst the Spiniphora sp. was considered an unknown species until it was linked to its male counterpart. The sealed waste bins were found to be accessible for the scuttle flies with delayed arrival (day 4-5). Megaselia scalaris was the primary scuttle fly species attracted to the carcass, and its occurrence could be observed between days 4-7 (replicate 1) and days 5-33 (replicate 2). This study also revealed Sarcophaga spp. (Diptera: Sarcophagidae) as the earliest species to colonize the remains and the longest to inhabit them (days 2-40). The larvae of Hermetia illucens (Linneaus) (Diptera: Stratiomyidae) and Fannia sp . (Diptera: Fanniidae) were found on the carcasses during the mid-advanced decay period.

Full Text Available By the 21st century, in most of Latin America a phased combination of international and civil society pressure has produced notable if incomplete human rights reform. Yet in Colombia, continuing assassinations, kidnappings, forced displacement, and torture have received limited international attention and met with a checkered state response. This essay will argue that the symbolic structure of the violations and political environment in Colombia, above and beyond material and institutional constraints, diminish civil society’s impact and state responsiveness. Communicative action and its failures are the key to the persistence of abuse and lag in international response in Colombia. Specifically, we will trace problems in the definition of rights, identification of victims, legitimacy claims of the state, discourse of causal attribution, and transnational communication dynamics.

Conflict fields of journalistic praxis in Colombia

Rousbeh Legatis

2010-10-01

Full Text Available The chronic uncertainty for journalists and editors in carrying out their professional work in Colombia has many sources and has been serious for decades. Currently – besides indicators of extreme physical violence (such as daily attacks, abuse, kidnappings and murders – problem areas are strongly marking journalistic work in Colombia that are often neglected in the international discussion, such as inadequate training offerings, unsatisfactory infrastructure in the workplace, precarious wage situations, lack of independence in relationship to editors and a poorly taught understanding of professional ethics. These structural problems produce qualitative deficiencies – especially in conflict reportage. But instead of stagnation, change is occurring. Colombian journalists are revising their self-image, at the same time developing a problem consciousness in their own work, and are actively trying to correct the deficiencies.

There are close to 120 species of native stingless bees in Colombia, many of them with important uses and meanings for diverse social and cultural groups. The stingless beekeeping (meliponiculture) is an activity in process of growth and technification in Latin America and other regions, but there are a little information about their characteristics and development in Colombia. Through information collected by interviews to 75 stingless beekeepers of 16 departments of Colombia, 25 species of stingless bees were identified, grouped in 12 genera. Approximately nine more uncertain species were also found, four new records for the country are presented, and geographical distribution, urban beekeeping and vernacular names reported. The characteristics of most common cultivated genera (Tetragonisca, Melipona, Paratrigona, Scaptotrigona and Nannotrigona) are presented, and the importance of the link between biological and cultural diversity revealed in vernacular names, are discussed. Facing a growing of meliponiculture in the world, some research needs and risks for the conservation and management of the diversity of stingless bees and related knowledge are remarked.

Full Text Available This article aims to show how the Law 1448 of 2011, which explains reparation and restitution of victims, and the National Development Plan (NDP 2011-2014 generate land concentration in Colombia. This is due to how the NDP objectives disintegrate the Law 1448 objectives; this phenomenon could be explained using an agency model and the subsequent moral risk issue formed between the State and the victims. Regarding these results, a game-theory model was built, and this effectively concludes that the Law 1448 and the NDP generate land concentration in ColombiaEn este artículo se pretende mostrar, mediante un análisis económico, cómo la Ley 1448 de 2011 (o Ley de Víctimas y Restitución de Tierras, junto al Plan Nacional de Desarrollo (PND 2011-2014, generan concentración de la tierra en Colombia.

Estudio de tipo descriptivo, transversal, que analiza la morbilidad atendida en consulta externa, hospitalización y urgencias en Colombia durante el quinquenio 2004-2008. MÉTODOS: Se utilizaron los "Registros individuales de prestación de servicios" (RIPS de Colombia, clasificándose los diagnósticos según los grupos de causas definidos por la Organización Mundial de la Salud. Cada grupo de causas para utilización de servicios se discriminó por región geográfica, género y régimen de afiliación al sistema de salud. RESULTADOS: Los diagnósticos de enfermedades transmisibles se encontraron más concentrados en los grupos de edad inferiores, mientras que las no transmisibles fueron más frecuentes en los grupos etarios superiores. Las externalidades (accidentes, lesiones autoinfligidas y violencia fueron una causa importante de morbilidad y afectaron con más fuerza a la población de entre 5 y 44 años de edad. Las patologías transmisibles fueron más prevalentes en mujeres (39,98% que en hombres (28%, en tanto que los hombres se vieron más afectados por las externalidades que las mujeres (18,5 y 7,3%, respectivamente. CONCLUSIONES: Si bien en Colombia han aumentado los diagnósticos de enfermedades no transmisibles, las infecciones siguen teniendo una presencia relevante en todos los grupos de edad y escenarios de prestación de servicios de salud. Tal situación exige revisar las políticas sanitarias para orientarlas no solo a mejorar la salud de la población sino también a reducir la brecha de servicios que existe entre las diferentes regiones del país.

Sirenomelia: two cases in Cali, Colombia.

Saldarriaga, Wilmar; Salcedo-Arellano, Maria Jimena; Ramirez-Cheyne, Julian

2015-01-30

We report two cases of sirenomelia, a rare congenital defect with a prevalence rate of 1:100 000 births; both cases were observed in Cali, Colombia. Both pregnant women were referred from Buenaventura, Colombia. The expecting mothers shared multiple adverse sociodemographic factors. Their homes were located in a city where the entire population is of low socioeconomic status living under conditions of extreme poverty. They were uneducated, with nutritional deficiencies and no access to drinking water most of the time. Both were exposed to water and fish from a nearby river contaminated with leachate from a poorly managed landfill. A similar relation was previously reported in Cali in 2005 between environmental factors and sirenomelia. We suggest that there is a common aetiological factor of environmental origin between these two sirenomelia cases and propose that exposure to derivatives from landfills should be included among the factors for this rare defect of multifactorial aetiological origin. 2015 BMJ Publishing Group Ltd.

Herein we describe a new species, Tillancoccus koreguajae Caballero & Ramos, sp. n. (Hemiptera: Coccidae) from Colombia collected on sugarcane. Pinnaspis strachani (Cooley) is also recorded on sugarcane for the first time worldwide. An updated list of seven species of Coccomorpha on sugarcane in Colombia is provided, including information on its distribution, biology, and mutualistic ants for each species. Seven species of scale insects (Hemiptera: Coccomorpha) have been recorded previously on sugarcane, Saccharum officinarum L. (Poaceae) in Colombia: Pseudococcidae: Dysmicoccus boninsis (Kuwana), D. brevipes (Cockerell), Pseudococcus calceolariae (Maskell), Saccharicoccus sacchari (Cockerell); Coccidae: Pulvinaria elongata Newstead; Diaspididae: Duplachionaspis divergens (Green) and Serenaspis minima (Maskell). However, the record of S. minima in Colombia is considered doubtful as there are no voucher specimens from Colombia and because the distribution of this species is currently limited to the Australasian region. Pseudococcus calceolariae is present in Colombia but its record on sugarcane is also doubtful. A taxonomic key for the identification of scale insects on sugarcane in Colombia is provided.

Full Text Available Para la década del noventa, la institucionalidad en Colombia se encontraba vulnerada frente a grandes carteles que traficaban y comercializaban con narcóticos. Fue en este contexto en el cual surgió el Plan Colombia, estrategia para recuperar la institucionalidad, reducir los cultivos ilícitos de coca y amapola, debilitar la economía de los grupos ilegales insurgentes, y finalmente recuperar la confianza inversionista. Hoy 13 años después de implementado el Plan, los cultivos ilícitos han tenido una disminución pero persisten, el tráfico y el comercio de psicoactivos han mutado y el consumo se ha incrementado, por lo tanto se cuenta con una necesidad social manifiesta por abordajes que realmente procuren un desarrollo sostenible y que den respuesta a una demanda comunitaria por acciones que procuren la prevención, la atención, el tratamiento y la rehabilitación de las personas, con servicios de salud adecuados. During the 1990's, institutionality in Colombia was negatively affected by large drug-dealing cartels. It was in this context where the Plan Colombia was born. This plan was a strategy to recover institutionality, reduce illegal coca and poppy plantations, weaken the economy of illegal insurgent groups, and restore investor confidence. Today, 13 years after the implementation of the Plan, the amount of illegal plantations has decreased. However they are still present, the traffic and trade of psychoactive substances have evolved, and consumption has increased. Therefore, there is now an evident societal need for strategies which address these issues that truly lead to sustainable development. Likewise, the community requires actions aimed at preventing this issue and promoting the care, treatment, and rehabilitation of those affected by this reality while providing adequate healthcare service

Determinar la productividad de Ae. aegypti en viviendas y espacios públicos de Girardot (Colombia, en época de lluvias y de sequía. Materiales y métodos. Se evaluó la productividad de pupas de Ae. aegypti en 20 conglomerados seleccionados aleatoriamente en Girardot, cada uno compuesto de 100 viviendas y sus espacios públicos. Se hizo una inspección en época de lluvias (febrero a mayo de 2011 y, otra, en época de sequía (agosto a septiembre de 2011. Se estimaron los índices de pupas en viviendas y en recipientes, así como el índice de Breteau, y los índices por persona y por hectárea. Resultados. En época de lluvias, las viviendas aportaron el 94 % de las pupas (n=7.098 y, los espacios públicos, el 6 % (n=482, y en época de sequía, el 98 % (n=9.138 y el 2 % (n=223, respectivamente. Las albercas y tanques bajos (>20 litros aportaron más del 87 % de las pupas en viviendas; los tarros, llantas y sumideros en espacios públicos fueron más productivos (≤20 litros. No se encontraron diferencias significativas en el índice de pupas por persona (lluvias=1,0; sequía=1,3, ni por hectárea (lluvias=0,96, sequía=0,45 (p>0,05. Los espacios públicos con más pupas en época de lluvias, fueron las zonas verdes y los lotes abandonados, y en época de sequía, los colegios y las calles. Conclusiones. La productividad de pupas de Ae. aegypti en las albercas y tanques bajos de las viviendas fue elevada tanto en la época de sequía como en la de lluvias, en tanto que los espacios públicos contribuyeron con más sitios de cría durante la época de lluvias. Las estrategias de control vectorial focalizadas en las pupas, permitirían un uso más racional y eficaz de los recursos.

Hepatitis E virus (HEV) is an emergent virus of global importance; it is the etiological agent of sporadic cases and outbreaks of hepatitis. The epidemiology of this infection in Colombia is unknown. To determine the seropositivity for hepatitis E virus in Colombia in cases with clinical diagnosis of viral hepatitis. Serum samples from patients that were sent to the Instituto Nacional de Salud during the period 2005-2010 (group 1) and samples sent to the Laboratorio Departamental de Salud Pública de Antioquia during the 2008-2009 period were included in this study (group 2). Serum samples were analyzed by immunoassay with commercial kits. From the 344 analyzed samples, 8.7% were positive for anti-HEV; the frequency of anti-HEV IgM was 1.74% (6/344) and the frequency of anti-HEV IgG was 7.5% (26/344). A difference in frequency of anti-HEV between group 1 (6.3%) and group 2 (1.3%) was observed. The cases were identified in nine departments of Colombia. This is the first study of hepatitis E virus infection in patients with diagnosis of hepatitis in Colombia. The frequency of anti-HEV described in this population of patients in Colombia is similar to that described in other Latin American countries like Brazil, Perú and Uruguay. Considering the results of this study, it could be necessary to include hepatitis E virus infection serological markers in the differential diagnosis of viral hepatitis in Colombia.

Morphology and conservation of the mesoamerican slider (Trachemys venusta, Emydidae) from the Atrato River Basin, Colombia; Morfologia y conservacion de la tortuga Hicotea Mesoamericana (Trachemys venusta, Emydidae) del Rio Atrato, Colombia

Ceballos, Claudia P; Brand, William A

The phylogenetic relationships of the mesoamerican slider, Trachemys venusta that inhabits the Atrato River Basin of Colombia have been controversial as three different names have been proposed during the last 12 years: T. v. venusta, T. v. uhrigi, and T. ornate venusta. Using a group of sliders that was confiscated by the regional authority we compared the morphology of T venusta distributed in the Atrato River with the morphology of the subspecies putatively distributed in Colombia. We found that the Colombian mesoamerican slider has an overall smaller size, different plastral inter-scute seam formula, and different head, carapace and plastron coloration patterns. In addition, we also report the poor health condition of these individuals that have endured this illegal trade. We underscore an urgent need for further studies of individuals indigenous to Colombia to better understand the phylogenetic relationships of T. venusta throughout its distributional range, along with a more effective control of the illegal turtle trade in the Uraba Region of Colombia.

Globalization and Language and Education Reform in Colombia: A Critical Outlook

Directory of Open Access Journals (Sweden)

Jaime Usma

2009-05-01

Full Text Available This paper explores the connection between economic, political, and cultural globalization processes and recent education and language reforms in Colombia. Throughout the article, the author attempts to demonstrate that current education and language policies in Colombia are tightly connected to transnational agendas and models of reform that do not necessarily represent a real benefit for the majority of the population, but, instead, may render privileges for a few. With this analysis, the author insists on the need for an equitable plan for the improvement of language teaching and learning in Colombia in a way that considers local priorities of economic development, respects local knowledge and culture, and accounts for a systemic and fundamental improvement of the public system based on the dissimilar conditions that affect schools, teachers, and students in both the private and the public sectors in the country.

In Colombia, the diversity of phlebotomine sand flies is high, with 162 recorded species, and which include vectors of Leishmania spp. To identify the sand fly species of medically importance in the area of influence from Amoyá River Hydroelectric Project, Colombia. Sand flies were collected with CDC light traps, Shannon traps and sticky traps, from 15 villages in Chaparral County,Tolima. A total of 1,077 adult sand fly specimens were collected. Thirteen species were found in the genus Lutzomyiaand one species in the genus Warileya.Among the Lutzomyia species, three species--Lutzomyia longiflocosa, Lutzomyia columbiana and Lutzomyia nuneztovari--are important for their epidemiological history.Lutzomyia suapiensis was a new record for Colombia, and Warileya rotundipennis was recorded for the first time in Tolima. This study contributed to an increased knowledge of Colombian sand flies in terms of (1) expanding the geographical distribution of members of the subfamily Phlebotominae, (2) gaining estimates of species-richness and species associations in central Colombia, and (3) providing a better understanding of epidemiology of leishmaniasis in the Chaparral area.

Full Text Available Se presenta una visión de largo plazo para la valoración de los avances en la equidad y en el derecho a la salud de la reforma del sistema de salud en Colombia. En medio de un sistema político restringido, los actores del campo de la salud en Colombia han construido opciones de tipo individualista que tienden a legalizar las desigualdades ligadas a la capacidad de pago de las personas. A pesar de los complejos mecanismos de regulación establecidos en el nuevo Sistema General de Seguridad Social en Salud, la tendencia apunta hacia una consolidación de las mismas desigualdades tradicionales y al distanciamiento de una garantía plena, equitativa y universal del derecho a la salud.The author develops a long-term perspective to assess advances in equity and the right to health in the Colombian health system reform. In a restricted political system, actors in the field of health in Colombia have chosen individualistic alternatives to legalize inequities in individual purchasing power for services. Despite the complex regulations established in the General System for Social Security in Health, there is a trend towards consolidating traditional inequities and to further restrict opportunities for achieving the right to health with full, equitable, universal guarantees.

Guzmán-Barragán, Blanca L; Días Bevilacqua, Paula; Nava-Tovar, Gerardo

2015-12-01

Objective This article aims to analyze comparatively the national surveillance systems of water quality for human consumption (DWQS) of Brazil and Colombia, seeking to understand how practices are organized in these countries, along with their limits and possibilities. Methods The National Cross Comparison methodology was used with document analysis of secondary sources, with the purpose of discussing the similarities and differences between the two systems using the WHO’s Guidelines for Drinking Water Quality. Results The legal framework on DWQS in Brazil and Colombia was defined in the 70s and 80s, coinciding with the international visibility of this issue. Thereafter, DWQS practices in Brazil have been defined and organized in a national program, which has only recently started in Colombia. The current Brazilian and Colombian legislations show progress in technical elements that guide surveillance practices, such as the incorporation of risk assessment methodologies. The Colombian legislation defines the regulation of water supply services provision, which is not contemplated in Brazilian legislation. Elements such as decentralization, intersectionality, universality and right to information are included in the legislations of both countries, although further action on DWQS is needed. Conclusions Brazil and Colombia have similarities in the implementation of DWQS, despite being at different points in the implementation timeline. Actions on drinking-water quality surveillance are necessary to guarantee human rights related to the protection of the environment, such as universal access to drinking water, contributing to the promotion of health.

Analyse of The Legal Framework in Colombia for implementation of Bioprospecting Practices

International Nuclear Information System (INIS)

Duarte, Oscar; Velho Lea

2008-01-01

The practice of bioprospecting is inherently linked with traditional knowledge and practices of local communities in the South as well as with the commercial activities of industries (e.g., pharmaceutics sector, agriculture) in the North. A series of actors operate at this interface, such as Non-Governmental Organizations (NGOs), Research Centers, Universities, Science and Technology sponsor institutions and the State. As these actors have divergent interests and powers of negotiation, an appropriate regulatory framework is necessary to regulate their interaction. This paper analyzes the existing legal framework in a mega-diverse country, like Colombia, for implementation of bioprospecting practices. The research consisted of two key components: (i) A review of the state of art of bioprospecting; (ii) A work in situ in Colombia, which consisted of analysis of information and genetic resources related to bioprospecting, participation in the implementation of a legal frame for bioprospecting practices and interviews with Colombian professionals in the field of biodiversity conservation. Our research determined that: (i) national authorities encounter a multitude of difficulties to implement a legal framework in Colombia, especially the Andean regional normativity; (ii) the execution of research projects related to bioprospecting in Colombia faces numerous challenges

Climatic projections and socio economic impacts of the climatic change in Colombia

Eslava R, Jesus Antonio; Pabon Caicedo, Jose Daniel

2001-01-01

For the task of working out climate change projections, different methodologies have been in use, from simple extrapolations to sophisticated statistical and mathematical tools. Today, the tools most used are the models of the general circulation of the atmosphere and ocean, which include many processes of other climate components (biosphere, cryosphere, continental surface models, etc.). Different global and regional scenarios have been generated with those models. They may be of great utility in calculating projections and future scenarios for Colombia, but the representation of the country's climate in those models has to be improved in order to get projections with a higher level of certainty. The application of climate models and of the techniques of down scaling in studies of climate change is new both in Colombia and tropical America, and was introduced through the National University of Colombia's project on local and national climate change. In the first phase of the project, version 3 of the CCM (Climate Community Model) of NCAR was implemented. Parallel to that, and based on national (grid) data, maps have been prepared of the monthly temperature and precipitation of Colombia, which were used to validate the model

Toro, Javier; Requena, Ignacio; Zamorano, Montserrat

2010-01-01

The evaluation of Environmental Impact Assessment (EIA) systems is a highly recommended strategy for enhancing their effectiveness and quality. This paper describes an evaluation of EIA in Colombia, using the model and the control mechanisms proposed and applied in other countries by Christopher Wood and Ortolano. The evaluation criteria used are based on Principles of Environmental Impact Assessment Best Practice, such as effectiveness and control features, and they were contrasted with the opinions of a panel of Colombian EIA experts as a means of validating the results of the study. The results found that EIA regulations in Colombia were ineffective because of limited scope, inadequate administrative support and the inexistence of effective control mechanisms and public participation. This analysis resulted in a series of recommendations regarding the further development of the EIA system in Colombia with a view to improving its quality and effectiveness.

The objective of this study was to describe the network structure and factors associated with collaboration in two networks that promote physical activity (PA) in Brazil and Colombia. Organizations that focus on studying and promoting PA in Brazil (35) and Colombia (53) were identified using a modified one-step reputational snowball sampling process. Participants completed an on-line survey between December 2008 and March 2009 for the Brazil network, and between April and June 2009 for the Colombia network. Network stochastic modeling was used to investigate the likelihood of reported inter-organizational collaboration. While structural features of networks were significant predictors of collaboration within each network, the coefficients and other network characteristics differed. Brazil's PA network was decentralized with a larger number of shared partnerships. Colombia's PA network was centralized and collaboration was influenced by perceived importance of peer organizations. On average, organizations in the PA network of Colombia reported facing more barriers (1.5 vs. 2.5 barriers) for collaboration. Future studies should focus on how these different network structures affect the implementation and uptake of evidence-based PA interventions. Copyright © 2011 Elsevier Ltd. All rights reserved.

Suicide is a serious public health problem worldwide, affecting all population groups, regardless of age, gender, or area of residence. The aim of this investigation was to characterise the recorded suicides in Colombia, between the years 2000 and 2010, according to the variables of the person, time and place. Descriptive quantitative study with information from secondary sources, from the death certificates of deceased people by suicide registered with the National Bureau of Statistics. The behaviour of the deaths and mortality, were determined using the denominator population projections of Colombia and the Amazon, Andean, Atlantic Coast, Eastern Plains and Pacific regions. Descriptive measurements and mortality rates were calculated using these. A total of 24,882 suicides were recorded in the eleven years studied, with a mean of 6.2 people per day, which increased to 8.0 during holidays The mean age of death was 34.5 years (men 36.4, women 27.7), with male deaths (78.1%) and urban areas (66%) predominating. The greatest risk of dying from this cause was recorded in the Eastern Plains, in young adults and seniors, and residents in rural areas. Suicide rates in Colombia show a downward trend, with a mean of 5.3/100,000 inhabitants, and with an increased risk in men (3.7 times the risk in women, in young adults (9/100,000). A higher death rate was recorded in single people in the months of December and January, and at weekends. Copyright © 2015 Asociación Colombiana de Psiquiatría. Publicado por Elsevier España.

Full Text Available Inventories on necrophagous insects carried out in Brazil encompass mostly species from the southeastern and central-western regions of the country. This review aims to produce the first checklist of necrophagous Diptera and Coleoptera species of forensic relevance in northeastern Brazil, an area that concentrates high rates of homicides. We performed a literature survey on scientific articles, theses and dissertations regarding necrophagous insect species in the region, and contacted scientists who develop research on forensic entomology. Fifty-two species of Diptera belonging to eight families with previous record of necrophagy were reported in the region: Sarcophagidae, Calliphoridae, Muscidae, Fanniidae, Piophilidae, Phoridae, Anthomyiidae and Stratiomyidae. Coleopteran species from six families of forensic relevance were registered, although taxonomical identification remained superficial. Bait traps were the most frequent methodology used, followed by collection on animal carcasses. Seven Dipteran species from two families were registered on human cadavers. All species had been previously reported in other Brazilian states and/or other countries, although none has been effectively used in legal procedures in the region. The status of research on forensic entomology in northeastern Brazil is incipient, and the checklist produced here contributes to the knowledge on the local diversity of necrophagous insects.Inventários de insetos necrófagos no Brasil abordam em sua maioria espécies das regiões Sudeste e Centro-Oeste do país.

Male-only clinics: a success story in Colombia.

Science.gov (United States)

Goldman, R

1987-04-01

2 male-only reproductive health clinics in Colombia are refuting the stereotype that Latin American men reject vasectomy as a threat to their machismo image and consider birth control to be a woman's responsibility. Over 1000 vasectomies were performed in the 2 clinics in Bogota and Medellin in 1986. The clinics are operated by PROFAMILIA and supported by the Association for Voluntary Surgical Contraception. Information about these male-only clinics is dispersed through radio announcements, magazine advertisements, and newspaper articles. The cost of services at these clinics is 50% less than services provided at other family facilities. These clinics demonstrate that Colombian men are willing to share family planning responsibilities if services are offered in a manner respectful of their needs. 3 additional male-only clinics are scheduled to open in Colombia in 1987.

Vegetation, population and ecological track as sustainability indicators in Colombia

International Nuclear Information System (INIS)

Marquez Calle, German

2000-01-01

Biophysical sustainability, namely natural capabilities to sustain human development in Colombia, is explored through environmental indicators based on land cover and demographic variables. Remnant vegetation index (IVR in Spanish) uses cover as a measure of ecosystem functionality. Population pressure index (IPD) applies population density to environmental demand analysis. Footprint index (IHE) relates the inverse of density with sustainability. Environmental criticality index combines IVR and IPD to detect offer/demand unbalances. Results suggest Colombia is sustainable although many places in it could be in danger; this could be related with social and economical features of the country

Full Text Available This research aims to conduct a descriptive study of the occurrence of human brucellosis in Colombia between 2000 and 2012, and, based on previous studies, to determine the prevalence and incidence of the disease, and the limitations for its timely diagnosis and recognition by the Colombian labor system. The research consisted of searching for and analyzing articles on human brucellosis published between 2000 and 2012 in Colombia. It included a phase of information gathering and unstructured interviews with representatives of brucellosis control programs and experienced professionals. We analyzed 17 studies of human brucellosis cases in personnel at risk in slaughterhouses, retailers and vaccinators for animal brucellosis programs: 10 of them reported prevalences between 0.14% and 10.4%, and seven evidenced seropositivity. Information revealed the limitations of the diagnosis, and it demonstrated the little knowledge of the medical community about this disease. In Colombia, there is no clear policy regarding this occupational zoonosis. Brucellosis is mentioned only in Decree 2566 of 2009, in which the new table of occupational diseases is established. The paper concludes that human brucellosis in Colombia is an underdiagnosed, and therefore underreported, disease since there is no mandatory reporting system on the subject.

González Medina, Alejandro; Soriano Hernando, Óscar; Jiménez Ríos, Gilberto

2015-05-01

Nonbiting midges (Diptera, Chironomidae) are the most abundant members of the fauna associated with submerged carcasses, but their use in the medicolegal context is very restricted because of their complex ontogeny. In this case, the corpse of a woman was recovered in late spring from a river in Granada (Iberian Peninsula). It showed obvious signs of long permanence in the aquatic environment and, along with pulmonary and microscopical analyses, led to the conclusion that the cause of death was drowning. Several larvae-like specimens were sampled from the scalp and later identified by morphological external features as IV instar larvae of Chironomus riparius Meigen, 1804 (Diptera, Chironomidae). Sequencing of cytochrome oxidase subunit I was performed to confirm the identification. The knowledge of the biology of C. riparius at low temperatures was critical to assess a postsubmersion interval of 16-17 days. © 2015 American Academy of Forensic Sciences.

Phlebotomus argentipes Annandale and Brunetti (Diptera: Psychodidae), the established vector for Visceral Leishmaniasis (VL) have shown some morphological variations in India and its subcontinents. The variable egg laying capacity was found in different morphotypes of P. argentipes with maximum in type III followed by type I and II. The fecundity was enhanced by providing 25% glucose soaked filter paper surface in all types. However, significant increase was found in type-I (P < 0.05). The differences in fecundity indicate the biological variations among P. argentipes population. The findings will be helpful in searching out the sibling species among P. argentipes population.

Campo-Arias, Adalberto; Herazo, Edwin

2015-01-01

Income inequality is directly related to the mental health of the population. However, the relationship between income inequality and suicide rates in Colombia has still not been explored. To estimate the relationship between inequality and suicide rates in Colombia from 1994 to 2013. An ecological study was conducted, in which the correlation was estimated (Spearman) between inequality (Gini coefficient) and suicide rate between 1994 and 2013, according to official information available from the National Administrative Department of Statistics (DANE), and the National Institute of Forensic Science and Forensic Medicine. A Gini coefficient between 0.53 and 0.60 (median, 0.65 [interquartile range, 0.54-0.57]) was observed, and suicide rates were between 3.84 and 5.26 (median, 4.20 [4.08-4.86]). The correlation between inequality and suicide rates was positive and statistically significant (r=.70; p<.001). There is a positive association between economic inequality and suicide rate in Colombia. It is important to achieve greater equity in the distribution of income to reduce suicide rate in the country. Copyright © 2014 Asociación Colombiana de Psiquiatría. Publicado por Elsevier España.

Sandfly collections were performed fortnightly between February 2006-September 2007 using automatic light traps, Shannon traps, protected human bait and aspiration in resting places. A total of 7,051 sandflies belonging to 12 species were captured. Pintomyia spinicrassa (95.7% predominated. Pintomyia oresbia and Lutzomyia sp. of Pichinde were found in the state of Norte de Santander for the first time. Pi. spinicrassa, Pintomyia nuneztovari, Micropygomyia venezuelensis, Lutzomyia (Helcocyrtomyia scorzai and Lu. (Helcocyrtomyia sp. were captured on the protected human bait. A significant association between Pi. spinicrassa abundance and the total rainfall and the average temperature and humidity 10 days before the collection was observed. The dominance of Pi. spinicrassa, a recognised vector of Leishmania braziliensis, especially during the dry periods, indicates that the risk of parasite transmission may increase.

FACCINI-MARTÍNEZ, Álvaro A.; BOTERO-GARCÍA, Carlos A.; HIDALGO, Marylin

2016-01-01

Colombian physician Luis Benigno Patiño Camargo was one of the pioneers in the study of rickettsioses in South America, demonstrating for the first time in Colombia the presence of Rickettsia rickettsii as the etiological agent of a highly deadly exanthematic febrile syndrome in the 1930s. However, Patiño-Camargo performed other investigations from 1917-1943, which represent the first descriptions and scientific evidence of the presence of R. prowazekii and R. typhi in Colombia. Almost 60 years after the latest research conducted by Dr. Patiño-Camargo, rickettsioses were again a matter of interest and research. In the last decade over 20 research studies have been published, showing new endemic areas for R. rickettsii, as well as the description of new rickettsial species in Colombia. PMID:27074327
