    Full Text Available INTRODUCTION: This is an unusual case presentation of a patient with symptoms of food poisoning along with two parasitic infections, both mode of infection being entirely different, with ascariasis due to ingestion of food contaminated with eggs of Ascaris lumbricoides and Ancylostoma duo denale due to hookworm penetration through skin ( B are - foot walking. CASE REPORT: A 48 year old female patient came with complaints of fever and loose stools for three days. Patient was an agriculturist by occupation with poor personal hygiene with a histo ry of consumption of meat two days prior to the symptoms. Laboratory test showed leukocytosis ( T otal count - 13,000 with both neutrophilic and eosinophilic predominance and anaemia. Microscopic examination of stool revealed the presence of plenty of p us cells and the presence of eggs of Ascaris lumbricoides and eggs of Ancylostoma duodenale. Also Salmonella typhimurium was isolated in the stool culture and confirmed at National Reference Centre. CONCLUSION: Food poisoning is a serious health problem. I t can cause severe illness and even death. Soil transmitted helminths are common among agriculturist. Washing hands with warm water and soap before handling foods, eating and after using toilets is mandatory to prevent food borne illness and parasitic infe ctions.

  4. Identification, isolation, and molecular cloning of a hookworm protease: an approach towards a defined vaccine for ancylostomiasis

    Hotez, P.J.


    The hookworm Ancylostoma caninum was shown to release in vitro a 37 kDa protease that catalyzed the hydrolysis of fibrinogen, plasminogen, and elastin. The enzyme was purified from parasite extracts by ion-exchange chromatography, followed by gel filtration and hydrophobic interaction chromatography. An amino-terminal sequence was determined. When assayed with radiolabeled fibrin as substrate, the enzyme displayed optimal activity at pH 9-11; it was inactivated by dialysis against ethylenediamine tetraacetic acid. Antiserum raised against the protease in rabbits cross-reacted on western blots with soluble antigen from the infective larval stage of the parasite. A cDNA library from hookworm mRNA was constructed in the expression vector bacteriophage lambdagtll. A positive clone was identified with the rabbit antiserum that was shown to contain an 800-bp insert. The insert was mapped, subcloned into M13, and sequenced, revealing an open reading frame of 789 nucleotides corresponding to 263 amino acids.

    This study was aimed; firstly to observe various clinical symptomatology with relation to the number of Ancylostoma duodenale larvae orally given to the human beings, secondly to evaluate the effects of some drugs like steroid hormones, antihistaminics and antitussives, and, thirdly to study the influences of some iron compounds in prevention and treatment of anemia of such origin. Ten healthy volunteers free from the previous history of hookworm infection were divided into 4 groups, to whom various numbers of actively moving filariform Ancylostoma duodenale larvae were orally given; 500 to 4 cases, 250 to 3 cases and 100 to 3 cases. Following were the results: 1. Clinical symptomatology. 1) The most frequently encountered symptoms and signs were general malaise, cough and hoarseness. The tracheal itching and pain, low back pain, arthralgia, sputum and salivation, acid belching, loss of appetite, abdominal pain and vomiting were also noted. 2) If the larger number of the larvae was given, the clinical symptomatology was more severe. 3) Prednisolone medication caused some improvement of such symptomatology, while the antihistaminics and antitussives like codeine or ephedrine were ineffective. 4) In volunteers whose nutritional conditions were rather poor appeared to show more severe symptomatology. 2. Effects of iron compounds. 1) The oral administration of ferrous fumarate induced a slight increase of serum iron levels in the initial stage of the infection, then a decrease from 15-20 days later and a recovery after 2 months. 2) The intravenous administration of saccharated ferric oxide induced a steady upkeep of the serum iron levels. 3) The hemoglobin contents also showed the upkeeps after either the oral or intravenous administration of the iron compounds. 4) The iron compounds, therefore, are considered to have the preventive as well as the therapeutic effects on hookworm anemia, which may strongly suggest that hookworm anemia is essentially the iron deficiency type. 3. Hematological changes. 1) The severity of hookworm anemia generally correlated with the number of larvae given. 2) The moderate leucocytosis was observed in all cases regardless of the number of larvae given, which reached to a peak in 25-35 days. 3) Eosinophilia was observed in all cases, but was more severe in cases given larger number of larvae, which was slightly less evident after the medication of prednisolone. 4) Red cell survival time. The red cell survival time determined by {sup 51}Cr was generally in the normal ranges except for the severe anemia patients.

    Wu, Fuquan; Xu, Ying; Xia, Min; Ying, Guanghui; Shou, Zhangfei


    Hookworm infections as well as other intestinal nematodiases are endemic in China. In this case, a 70-year-old male showed symptoms of chest tightness, shortness of breath, and both lower extremities edema. The diagnostic result was chronic renal insufficiency, chronic kidney disease (5th stage), and renal anemia at first. Then, he received treatment with traditional drugs. However, this treatment did not help to alleviate the symptoms of the patient significantly. The results of gastroendoscopy showed hookworms in the duodenum, also confirmed by pathology examination. Anemia was markedly ameliorated after eliminating the parasites. The results mentioned above suggested that ancylostomiasis was the leading causes of anemia in this patient, and the etiology of anemia in uremic patients should be systematically considered. Especially when anemia could not be cured by regular treatments, rare diseases should be investigated. PMID:27417086

  11. Albendazole, a broad-spectrum anthelmintic, in the treatment of intestinal nematode and cestode infection: a multicenter study in 480 patients. (United States)

    Jagota, S C


    The anthelmintic activity of and patient tolerance to albendazole, a broad-spectrum anthelmintic, were studied in a multicenter trial involving 480 patients ranging in age from 2 to 60 years. The patients had single or mixed infections caused by pinworms, roundworms, hookworms, whipworms, threadworms, or tapeworms. The stools were examined by the direct method, and ova were counted by means of the Kato-Katz technique. A Graham-Scotch test was also done in patients infected with Enterobius vermicularis. Most patients received a single 400-mg dose of albendazole; adults were given two tablets, and children were given a 2% suspension. All patients with Hymenolepis nana and about half of those with Taenia infections were treated for three successive days. Patients were carefully evaluated before and after treatment to assess the efficacy and safety of the drug. After a single dose of albendazole, the cure rate was 95.3% in ascariasis, 92.2% in ancylostomiasis, 90.5% in trichuriasis, 64.9% in taeniasis, and 100% in enterobiasis. Among patients receiving 400 mg of albendazole for three days, the cure rate was 63.4% in hymenolepiasis and 86.1% in taeniasis. The drug was well tolerated, and no significant side effects were reported. PMID:3516398

    One hundred sixteen children between 2 and 15 years of age entered a clinical trial of albendazole after examination of their stools revealed ova of one or more intestinal helminths. The drug was administered as a single 400-mg dose (20 ml of 2% suspension) to all the patients except those having Hymenolepis nana infection, who received treatment for three consecutive days. The stools were reexamined on days 7 and 14 posttreatment and after three months for Taenia infections. Patients were considered cured if all parasitological examinations of the feces were negative after treatment. After a single oral dose, albendazole was highly effective in ascariasis (91.9%), ancylostomiasis caused by Ancylostoma duodenale (87.2%), and H nana infection (71.4%). The drug was well tolerated, and no abnormalities were observed in hematological or blood chemistry values. Since the drug is safe and effective as a single-dose treatment of common helminthic infections, it should be considered for mass therapy in the community. PMID:3986860

    Wiśniewski, Marcin; Łapiński, Maciej; Daniłowicz-Luebert, Emilia; Jaros, Sławomir; Długosz, Ewa; Wędrychowicz, Halina


    Hookworms, a group to which Ancylostoma ceylanicum belongs, are gastrointestinal nematodes that infect more than 700 million people around the world. They are a leading cause of anemia in developing countries. In order to effectively prevent hookworm infections research is conducted to develop an effective vaccine using recombinant antigens of the parasite. The aim of this study was to examine the influence of the hosts' on protection against ancylostomiasis and the shaping of the humoral immune response among Syrian hamsters after immunization with a cocktail of five A. ceylanicum recombinant antigens. Ace-ASP-3, Ace-ASP-4, Ace-APR-1, Ace-MEP-6 and Ace-MEP-7 were obtained in the pET expression system. Immunization with a vaccine cocktail resulted in a 33.5% worm burden reduction. The immunogenicity of the recombinant proteins were determined using ELISA. Statistical analysis showed that vaccinated hamsters developed stronger humoral responses to four of five recombinant antigens (the exception being Ace-ASP-3) compared to hamsters from the control group.

    Full Text Available The use of pyrantel pamoate in controlling soil transmitted helminthic infection has been studied in a sample of population on low socio-economic level, consisting of workers of the Madukismo Suger Estate and their families. Pyrantel pamoate proved to be more effective to Ascaris lumbricoides and hookworm than to Trichuris trichiura infection. The cure rates found were 90.2%, 57.5% and 3.7% for A. lumbricoides, hookworm and T. trichiura respectively, while in the hookworm infection the drug was more effective to Ancylostomiasis duodenale than to Necator americanus. The result of the study showed, that 6 months after treatment was still found a reduction of the prevalence of A. lumbricoides infection to 27.2% (from 74.4% to 47.2% and a reduction of the egg count from 6352 to 3348 per gram of stool. After one year the prevalence rate and the intensity of Ascaris infection reached almost the same level as that before treatment. As regards the hookworm infection, it seemed that the treatment was still effective after a period of one year. Prior to the treatment the prevalence rate was 36.3% and the egg count was J37 per gram of stool, while one year after treatment they were still reduced to 23.97c and 39 respectively.

    Full Text Available Foram estudados 10 doentes, portadores de anemia ancilostomótica e de grande parasitose. Foram determinados alguns parâmetros hematológicos como dosagem de hemoglobina, contagem de hemácias, hematócrito, volume corpuscular médio, hemoglobina corpuscular média, ferro sérico e siderofilina. Foram estudados o volume da perda de sangue intestinal, o ferro perdido nesta hemorragia e eliminado nas fezes, e o ferro reaborvido da hemorragia intestinal. Conclui-se que a reabsorção do ferro da hemoglobina por dia no tubo digestivo é de suma importância no retardamento da instalação da anemia ferropriva, causada pela parasitose ancilostomótica.Ten patients presenting ancylostomotic anemia and a high rate of parasitosis were submitted to several hematologic determinations: hemoglobin level, erythrocyte count, hematocrit, mean corpuscular volume, mean corpuscular hemoglobin, serum iron level, and transferrin. In addition, measurements were made of the blood volume lost by intestinal bleeding, of iron loss through hemorrhage and in feus, and of iron reabsorption from intestinal bleeding. The main reason for the late appearance of iron deficiency anemia in ancylostomiasis is the high degree of dally iron absorption in the digestive tract, originating from hemoglobin breakdown.

  17. Hamsters vaccinated with Ace-mep-7 DNA vaccine produced protective immunity against Ancylostoma ceylanicum infection. (United States)

    Wiśniewski, Marcin; Jaros, Sławomir; Bąska, Piotr; Cappello, Michael; Długosz, Ewa; Wędrychowicz, Halina


    Hookworms are intestinal nematodes that infect up to 740 million people, mostly in tropical and subtropical regions. Adult worms suck blood from damaged vessels in the gut mucosa, digesting hemoglobin using aspartic-, cysteine- and metalloproteases. Targeting aspartic hemoglobinases using drugs or vaccines is therefore a promising approach to ancylostomiasis control. Based on homology to metalloproteases from other hookworm species, we cloned the Ancylostoma ceylanicum metalloprotease 7 cDNA (Ace-mep-7). The corresponding Ace-MEP-7 protein has a predicted molecular mass of 98.8 kDa. The homology to metallopeptidases from other hookworm species and its predicted transmembrane region support the hypothesis that Ace-MEP-7 may be involved in hemoglobin digestion in the hookworm gastrointestinal tract, especially that our analyses show expression of Ace-mep-7 in the adult stage of the parasite. Immunization of Syrian golden hamsters with Ace-mep-7 cDNA resulted in 50% (p < 0.01) intestinal worm burden reduction. Additionally 78% (p < 0.05) egg count reduction in both sexes was observed. These results suggest that immunization with Ace-mep-7 may contribute to reduction in egg count released into the environment during the A. ceylanicum infection. PMID:26795262

  20. Molecular cloning and analysis of Ancylostoma ceylanicum glutamate-cysteine ligase. (United States)

    Wiśniewski, Marcin; Lapiński, Maciej; Zdziarska, Anna; Długosz, Ewa; Bąska, Piotr


    Glutamate-cysteine ligase (GCL) is a heterodimer enzyme composed of a catalytic subunit (GCLC) and a modifier subunit (GCLM). This enzyme catalyses the synthesis of γ-glutamylcysteine, a precursor of glutathione. cDNAs of the putative glutamate-cysteine ligase catalytic (Ace-GCLC) and modifier subunits (Ace-GCLM) of Ancylostoma ceylanicum were cloned using the RACE-PCR amplification method. The Ace-gclc and Ace-gclm cDNAs encode proteins with 655 and 254 amino acids and calculated molecular masses of 74.76 and 28.51kDa, respectively. The Ace-GCLC amino acid sequence shares about 70% identity and 80% sequence similarity with orthologs in Loa loa, Onchocerca volvulus, Brugia malayi, and Ascaris suum, whereas the Ace-GCLM amino acid sequence has only about 30% sequence identity and 50% similarity to homologous proteins in those species. Real-time PCR analysis of mRNA expression in L3, serum stimulated L3 and adult stages of A. ceylanicum showed the highest level of Ace-GCLC and Ace-GCLM expression occurred in adult worms. No differences were detected among adult hookworms harvested 21 and 35dpi indicating expression of Ace-gclc and Ace-gclm in adult worms is constant during the course of infection. Positive interaction between two subunits of glutamate-cysteine ligase was detected using the yeast two-hybrid system, and by specific enzymatic reaction. Ace-GCL is an intracellular enzyme and is not exposed to the host immune system. Thus, as expected, we did not detect IgG antibodies against Ace-GCLC or Ace-GCLM on days 21, 60 and 120 of A. ceylanicum infection in hamsters. Furthermore, vaccination with one or both antigens did not reduce worm burdens, and resulted in no improvement of clinical parameters (hematocrit and hemoglobin) of infected hamsters. Therefore, due to the significant role of the enzyme in parasite metabolism, our analyses raises hope for the development of a successful new drug against ancylostomiasis based on the specific GCL inhibitor.

    Objective To detect infection of Angiostrongylus cantonensis and examine effection of treatment to prepare monoclonal antibodies(McAbs). Methods Six-week-old BALB/c mice were imrnunized by the intraperitoneal injection of e/s antigens of Angiostrongylus cantonensis. Fusion of splecn cells from immunized mice with prepared SP2/0-Ag14 myeloma cells was performed in RPMI 1640. Fused cells were suspended in RPMI 1640 containing 1% HAT and 20% fetal calf serum and dispensed into 96-well cell culture plates. The supernatants of clones were screened by ELISA with sera of patients of angiostrongyliasis.Distribution of cohere antigen of 12D5 and 21B7 monoclonal antibodies was analyzed with immunohistochemistry. Two McAbs ( 12D5 and 21B7) were applied to detect the circulating antigen (CAg) in the sera of rats infected with A. cantonensis and angiostrongyliasis patients respectively by double antibody sandwich ELISA.Results 12D5 McAb was identified as IgG1 and 21 B7 McAb was IgM. Western blot result showed two McAbs could used to identified 55 × 103 protein of adult worms of A. cantonensis. Cohere antigen of 12D5 and 21B7 monoclonal antibodies were distributed on intestine surface of A. cantonensis. The detection rates of CAg in the sera of infected rats 100% (48/48), the detection rates of CAg in the sera of angiostrongyliasis patients was 100% (32/32). No cross-reaction to sera of patients with other infection of parasites, such as clonochiasis, fasiolopsiasis, ancylostomiasis, trichinosis, anisakiasis as well as schsitosomiasis, and health srea did not reacted with 12D5 and 21B7 McAbs,and detaction rate of antibody of angiostrongyliasis patients only reached 75% (24/32) with antigen of A. cantonensis. Conclusion Cohere antigen of 12D5 and 21B7monoclonal antibodies were antigens of enteric epithelium. Sandwich ELISA with 12D5 and 21B7 McAbs showed high specificity act as detecting CAg of A. cantonensis in sera of infection animal and patients. It is apparent that Sandwich

    envueltos en la prueba de una vacuna contra anquilostomiasis. La muestra por conveniencia estaba constituida por 13 estudiantes de diez a 17 años, de ambos sexos, de la Escuela Municipal de Maranhao, MG, Brasil, 2009. Se utilizó un cuestionario estructurado aplicado pre y post intervención. El dispositivo pedagógico fue el Teatro del Oprimido. Las variables dependientes fueron el conocimiento específico y global sobre la investigación clínica y sobre helmintiasis; la variable independiente fue la participación en la intervención educativa. RESULTADOS: Hubo aumento del conocimiento sobre señales y síntomas, susceptibilidad a la reinfección y modo de contagio de la helmintiasis posterior a la intervención educativa. Aumentaron los aciertos relativos a la duración de la investigación clínica, a los procedimientos previstos, a la posibilidad de desistencia de la participación y de ocurrencia de eventos adversos. Permaneció la noción de que el propósito primario de la investigación es terapéutico, a pesar de que hubo reducción en el porcentaje de participantes que asociaron la investigación al tratamiento médico. El Teatro del Oprimido posibilitó que las discusiones sobre helmintiasis y de la investigación clínica fueran contextualizadas y materializadas. Los individuos pudieron despojarse o reducir sus representaciones previas. CONCLUSIONES: La participación de niños y adolescentes en ensayos clínicos debe ser precedida por intervención educativa, ya que individuos de ese grupo etario no pudieron siquiera reconocer que tienen derecho a decidir por sí mismos.OBJECTIVE: To analyze the effects of a pedagogical intervention on the learning of children and teenagers participating in a clinical research. METHODS: Quantitative, quasi-experimental and longitudinal study, part of a group of studies conducted to test a vaccine against ancylostomiasis.
