A field trials were conducted to assess the helminth parasites of 12 marsh frogs (Rana ridibunda ridibunda) in the Anzali, Astara and Aghbaba regions in the north of Iran in May 1994. Experimental results showed that 83.8% of the Anzali marsh frogs were infected by one or two kinds of metacercarian cysts of digenetic trematodes. The helminth parasites were included Skrjabinoeces breviansa, S. s...

introduction: there is not much data on parasitic infections of laboratory animals that are kept in conventional conditions in iran. the present study was designed to investigate intestinal helminths infections in laboratory colonies of rats and mice. methods: droppings from 110 mice and 110 rats (each animal one dropping) belonging to experimental and breeding groups in four animal houses were...

BACKGROUND Deworming HIV-1 infected individuals may delay HIV-1 disease progression. It is important to determine the prevalence and correlates of HIV-1/helminth co-infection in helminth-endemic areas. METHODS HIV-1 infected individuals (CD4>250 cells/ul) were screened for helminth infection at ten sites in Kenya. Prevalence and correlates of helminth infection were determined. A subset of in...

introduction: intestinal parasites have world wide prevalence and are considered to be as one of the leading hygienic and economic problems in the world. it can be said that there is nowhere in the world without parasitic infestations. the present study was conducted to determine the prevalence of intestinal parasites in patients referring to yazd central laboratory in 2000-2002. methods: the p...

Canids are reservoir for some zoonoses helminthic disease. They are one of main public health problem. Theaim of this study was to ascertain frequency of gastrointestinal helminthic infection of stray dogs in Zabol city,southeaster of Iran. In this descriptive study, 30 stray dogs were euthanized, intestine was removed by necropsy.Then, the intestines was opened by scalpel and their contents pa...

Helminth infections affect more than a third of the world's population. Despite very broad phylogenetic differences among helminth parasite species, a systemic Th2 host immune response is typically associated with long-term helminth infections, also known as the "helminth effect". Many investigations have been carried out to study host gene expression profiles during helminth infections. The ob...

Helminths have evolved numerous pathways to prevent their expulsion or elimination from the host to ensure long-term survival. During infection, they target numerous host cells, including macrophages, to induce an alternatively activated phenotype, which aids elimination of infection, tissue repair, and wound healing. Multiple animal-based studies have demonstrated a significant reduction or co...

BACKGROUND The effect of helminth infections on allergic diseases is still inconclusive. Furthermore, the effect of helminth infections on childhood allergic diseases in a tropical area where prevalence of helminth infections has undergone dramatic changes is not well documented. OBJECTIVE To investigate the relationship between allergic diseases and helminth infection in a cohort of schoolch...

BACKGROUND Infection with intestinal helminths may stimulate dysfunctional immune responses in human immunodeficiency virus (HIV)-infected persons. Studies have yielded conflicting results regarding the impact of antihelminthic treatment on plasma concentrations of HIV-1 RNA.Methods. We conducted a prospective study of 54 HIV-1- and helminth-coinfected and 57 HIV-1-infected, helminth-uninfected...
