While hosts are routinely exploited by a community of parasite species, the principles governing host responses towards parasites are unclear. Identifying the health outcomes of coinfections involving helminth macroparasites and microparasites is one area of importance for public and domestic animal health. For instance, it is controversial how deworming programmes affect incidence and severity...

By reputation, the parasite is a pariah, an unwelcome guest. Infection with helminth parasites evokes stereotypic immune responses in humans and mice that are dominated by T helper (Th)-2 responses; thus, a hypothesis arises that infection with helminths would limit immunopathology in concomitant inflammatory disease. Although infection with some species of helminths can cause devastating disea...

BACKGROUND Helminth infection is common in malaria endemic areas, and an interaction between the two would be of considerable public health importance. Animal models suggest that helminth infections may increase susceptibility to malaria, but epidemiological data has been limited and contradictory. METHODOLOGY/PRINCIPAL FINDINGS In a vaccine trial, we studied 387 one- to six-year-old children...

BACKGROUND M. tuberculosis and helminth infection each affects one third of the world population. Helminth infections down regulate cell mediated immune responses and this may contribute to lower efficacy of BCG vaccination and higher prevalence of tuberculosis. OBJECTIVE To determine the effect of maternal helminth infection on maternal and neonatal immune function and immunity to TB. METH...

Understanding the impact of helminth infections on clinical malaria is useful for designing effective malaria control strategies. Plenty of epidemiological studies have been conducted to unravel the nature of interactions between Plasmodium and helminth infection. Careful broad summarization of the existing literature suggests that Schistosoma mansoni and hookworm infections may increase the ri...

This study was done to assess the risk of helminth infection in association with wastewater-fed rice cultivation in an agricultural setting of Nam Dinh city, Vietnam. In a cross sectional survey data were collected for 202 households in a commune where wastewater was used for irrigation and for 201 households in a commune that used river water. Parasitological examination was conducted on singl...

BACKGROUND Helminth infections are highly prevalent in tropical and subtropical countries, coexisting in Chagas disease endemic areas. Helminth infections in humans may modulate the host immune system, changing the Th1/Th2 polarization. This immunological disturbance could modify the immune response to other infections. The aim of this study is to evaluate the relationship between clinical, mic...

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 infection provides a unique challenge to the host immune system. Not only are helminths complex multicellular organisms, but they have intricate life cycles with multiple developmental stages, several of which may coexist in the infected host. In most cases, the host response to helminth infection is characterized by eosinophilia, increased serum immunoglobulin (Ig) E and IgG4, and mas...
