A total of 111 samples (43 faeces and 79 gastrointestinal tracts) of 14 wild carnivore species from 12 Argentine provinces were analyzed. Helminth eggs were identified in 73% of the faecal samples and adult worms were recovered from 81% of the gastrointestinal tracts. We found 19 helminth species. Among the most frequent findings were parasites of domestic carnivores, namely Toxocara canis, Tox...

Background The effect of helminth infections on allergic diseases is still inconclusive. Several studies show that Treg cell induced by parasites down regulate the host Th2-mediated allergic response. However, some studies highlight the importance of alternative activated macrophages (AAM) in the pathogenesis of allergic diseases. This phenotype is also implicated in helminth survival. Our aim ...

Examination of coprolites excavated from archaeological sites in the Americas demonstrates excellent preservation of helminth eggs and, in some cases, larvae. To gain an understanding of helminth parasitism in prehistory on the Colorado Plateau of Arizona, New Mexico, and Utah, 319 coprolites from 5 archaeological sites were analyzed. Helminth eggs and larvae were recovered after the coprolites...

Nearly one quarter of the world's population is infected with helminth parasites. A common feature of helminth infections is the manifestation of a type 2 immune response, characterized by T helper 2 (Th2) cells that mediate anti-helminth immunity. In addition, recent literature describes a close association between type 2 immune responses and wound repair, suggesting that a Th2 response may co...

2034 www.thelancet.com Vol 390 November 4, 2017 Epidemiological studies have found an inverse relationship between exposure to helminth parasites and the incidence of inflammatory and autoimmune disease. Evidence from animal studies shows that helminth infections exert strong immunomodulatory activity and are able to inhibit, alter, and modify immune responses. Their ability to alter or suppres...

Fourteen adult frogs including six banded frog, Rana camerani and eight marsh frog, Rana ridibunda ridibunda were collected from two sites of Chahar Mahal-o-Bakhtiari province at the southwest of Iran and then were examined for helminth parasites. Only Dolichosaccus rastellus  (50%) was found in R. camerani, Skrjabinoeces similis (50%) and metacercarian cysts of Codonocephalus urniger (12.5%) w...

Twelve Bonsmara tracer calves (aged 6-12 months) were used to monitor helminth infections in the communal farming system of Botshabelo in the Free State. One calve was slaughtered each month from December 1995 to November 1996 and processed for helminth recovery. All the calves harboured worms, but the numbers were always low. The order of prevalence of the major parasites was Trichostrongylus ...

present research was for study on parasitic infections of domestic ruminants in golestan province. 234 samples of the gastrointestinal tracts contents, 260 livers, 180 lungs, 350 hearts and muscles, 300 abdominal cavities and 100 eyes for infection to helminthes, 800 blood samples for protozoa and external coats of 700 animals were examined for arthropoda. results showed that 19.74% of sheep ga...

May 2005 1867 ABSTRACT A coprological survey was made to assess the spectrum of helminth parasites in Mithun and other co-existing wild livestock in Bhutan and neighbouring Arunachal Pradesh (India). Nematodes with direct life cycle were found to be most predominant helminth infection among these animals. Cestodes and trematodes were poorly represented as their occurrence is primarily determine...
