Macropathogens, such as multicellular helminths, are considered masters of immunoregulation due to their ability to escape host defense and establish chronic infections. Molecular crosstalk between the host and the parasite starts immediately after their encounter, which influences the course and development of both the innate and adaptive arms of the immune response. Helminths can modulate den...

Helminths modulate both the adaptive and innate arms of human immune system. Such immune alteration seems to have an anti-inflammatory effect. Chronic helminth infections switch the immune response from Th1 to Th2 by various mechanisms and by different helminth derived molecules. Though these immunological responses provide a survival advantage, they seem to hamper the response to non-helminth ...

SUMMARY For detem1inating the prevalence of pathogenic protozoa and helminths in the Shahrood city and comparative between efficacy of metronidazole and Quinacrine in 1372-1373.from I 6649 students, 1043 students selected randomly and stool examination was done by direct and concentration with fonnol ether methods. Among the pathogenic protozoa prevalence of Giardia lamblia Emamoeba histolytic...

By definition, parasites harm their hosts. Yet substantial evidence from animal models of human disease support the hypothesis that infection with helminths can suppress the development of other maladies. Here, the view is presented that assessment of the immunophysiological response to helminths could identify that infection with specific parasites would be therapeutically useful (although man...

Infection with intestinal helminths results in immunological changes that influence co-infections, and might influence fecundity by inducing immunological states affecting conception and pregnancy. We investigated associations between intestinal helminths and fertility in women, using 9 years of longitudinal data from 986 Bolivian forager-horticulturalists, experiencing natural fertility and 70...

Reports of case-studies as well as estimates of disease in local and regional populations provide us with patterns of disease that are subject to a variety of local environmental, societal, and biological influences. Environmental conditions are significantly influenced in turn by climate and human activities. All of these influences can be highly variable, resulting in very different patterns ...

abattoir survey was carried out to determine the prevalence of gastrointestinal helminths and the seasonal fluctuations in intestinal worm burdens and faecal worm egg counts of camel in khorasan razavi province in the northeast of iran. a total of 306 dromedaries (camelus dromedarius) in the mashhad abattoir, in the northeast of iran and the capital of khorasanprovince were examined between oct...

We collected fecal samples from 500 dogs and 300 cats from an animal refuge in Nakhon Nayok Province, Thailand to test for gastrointestinal protozoa and helminths using a formalin-ether concentration technique. The overall prevalence of parasites in stool from dogs was 36.2% (181/500), 35.7% (177/500) had helminths and 2.8% (14/500) had protozoa. The helminths were: hookworm (30.6%), Trichuris ...
