Substance P Signaling Contributes to Granuloma Formation in Taenia crassiceps Infection, a Murine Model of Cysticercosis  

UK PubMed Central (United Kingdom)

Cysticercosis is an infection with larval cysts of the cestode Taenia solium. Through pathways that are incompletely understood, dying parasites initiate a granulomatous reaction that,...Full Text Available

Sympatric Distribution of Three Human Taenia Tapeworms Collected between 1935 and 2005 in Korea  

Science.gov (United States)

Taeniasis has been known as one of the prevalent parasitic infections in Korea. Until recently, Taenia saginata had long been considered a dominant, and widely distributed species but epidemiological profiles of human Taenia species in Korea still remain unclear. In order to better understand distribution patterns of human Taenia tapeworms in Korea, partial nucleotide sequences of mitochondrial cox1 and ITS2 (internal transcribed spacer 2) were determined, along with morphological examinations, on 68 Taenia specimens obtained from university museum collections deposited since 1935. Genomic DNA was extracted from formalin-preserved specimens. Phylogenetic relationships among the genotypes (cox1 haplotype) detected in this study were inferred using the neighbor-joining method as a tree building method. Morphological and genetic analyses identified 3 specimens as T. solium, 51 ...

Analysis of brain CT on 120 patients of human cysticercosis  

International Nuclear Information System (INIS)

A study on brain CT was made in 120 patients of human cysticercosis, which is a rare disease in Japan and clinical symptoms and laboratory data for the diagnosis were also discussed. From the point of therapeutic view, we proposed a new differentiation on brain CT of human cysticercosis, which is divided into two groups according to the alve or dead parasite. Furthermore, we proposed a new type named multiple large and small cysts type on brain CT. The idea of diagnostic standard was made integrating brain CT image, clinical symptoms and labolatory data.

The effects of different plant extracts on intestinal cestodes and on trematodes  

British Library Electronic Table of Contents (United Kingdom)

In the present study, chloroform, aqueous, (polyethylene glycol/propylene carbonate) PEG/PC extracts were made from coconut, onion, garlic, fig, date tree, chicory, ananas, and cistrose. These extracts were tested in vivo and in vitro on their anthelmintic activity against cestodes (Hymenolepis diminuta, H. microstoma, Taenia taeniaeformis) and trematodes (Fasciola hepatica, Echinostoma caproni). In all in vitro tests, the target parasites died. It turned out that the treatment of mice and rats with a combination of onion and coconut extracts (with PEG/PC) eliminated all cestodes from their final hosts. In addition, the same composition was effective against the intestinal fluke E. caproni, but not against the liver fluke F. hepatica in the final host, while both worms were killed in vitro...

Helminth parasites in faecal samples from the endangered Iberian lynx (Lynx pardinus)  

British Library Electronic Table of Contents (United Kingdom)

The Iberian lynx is the most endangered felid in the world. Enteropathogens may threaten its survival, and therefore we analysed faecal samples from 66 different individuals (37 males and 29 females), the largest population representation studied to date. The samples were obtained from November 2005 to October 2008 in the two areas where the Iberian lynx survives: Sierra Morena and Donana (Andalusia, southern Spain). A total of 56.1% samples were parasitized with at least 6 species of helminths, including two cestodes (Hymenolepis spp. and Taenia spp.) and four Nematodes (Ancylostoma spp., Toxocara spp., Toxascaris leonina, and Capillaria sp.). In this work, the presence of Hymenolepis is reported for the first time in Lynx pardinus. The relevance of our findings is discussed focussed on t...
