background: for a long time, intestinal parasite infections are among the major problems of public health in iran. our aim was epidemiological studies on the frequency of intestinal parasites in patients re­ferred to three hospitals in tehran during 2007-2008. methods : during 2007-2008, by simple random selection, 1000 stool samples were collected from mi­lad, hazrat-e-rasoul and shahid fahmid...

BACKGROUND The aim of the study was to determine the helminthic species occurring in great gerbil Rhombomys opimus collected from Maraveh Tappeh, Golestan Province, northeast Iran. METHODS During 2010-2011, a total of 77 R. opimus were captured from rural areas of Maraveh Tappeh, Golestan Province, using Sherman live traps and examined for infectivity with any larva or adult stages of helmint...

The nematode parasites that cause human lymphatic filariasis survive for long periods in their vascular habitats despite continual exposure to host cells. Since prostanoids formed from arachidonic acid can modulate interactions among platelets, leukocytes, and endothelial cells, we examined whether intravascular nematode parasites can elaborate prostanoids. Microfilariae of Brugia malayi utiliz...

There have been numerous studies in the mouse illustrating the dichotomy of T cell responses, with the common classification orchestrated around Th1 vs. Th2 responses. This classification is now widely applied to human disease as well and the generic conclusion is that the Th1 responses are more likely to occur secondary to specific microbiologic insult but also inflammatory responses. In contr...

More than one-third of the world's population is infected with one or more helminthic parasites. Helminth infections are prevalent throughout tropical and subtropical regions where malaria pathogens are transmitted. Malaria is the most widespread and deadliest parasitic disease. The severity of the disease is strongly related to parasite density and the host's immune responses. Furthermore, coi...

Common environmental allergens stimulate IgE responses and produce allergic disease, but the allergens that produce the most potent IgE responses in nature originate from helminthic parasites. 1 2 Since parasitic infection is endemic in the majority of the world's population , the relationship between helminthic infection and the IgE response is highly relevant to the understanding of allergic ...

Soil transmitted helminthiasis (STH) represents a major public health problem in tropical regions. In many countries including Senegal, STH control strategies usually involve mass deworming campaigns. This study was carried out to assess the prevalence and distribution of intestinal parasites among children, several years after the initiation of mass deworming campaigns with mebendazole in Sene...
