previous reports on intestinal parasite from isfahan area revealed wide distribution of intestinal parasitic infections in the area. since all studied areas were situated in the banks of zayandeh rood river with lot of trees and a humid soil, it was suggested, for comparison, to undertake a similar study in a village with comparatively dry and district climate. the village segzi (42 kilometer, ...

Intestinal parasite infections are major public health problems of children in developing countries causing undernutrition, anemia, intestinal obstruction and mental and physical growth retardation. This study was conducted to assess the prevalence of intestinal helminthic infections among children under five years of age with emphasis on Schistosoma mansoni in Wonji Shoa Sugar Estate, Ethiopia...

Background. Malaria is prevalent in sub-Saharan Africa, where other concomitant parasitic infections, including intestinal helminths, are common. However, little is known about how concurrent infections affect the expression or pathogenesis of each other. This study aimed to document the prevalence rates of malaria and intestinal helminths individually and as coinfection among asymptomatic chil...

Intestinal parasites are frequently transmitted via contaminated food or drinking water, but may also be spread from person to person through fecal-oral contact. Intestinal protozoan and helminth parasites are widely prevalent causing considerable medical and public health problems in developing countries. Intestinal parasitic protozoal and helminthic infections are widely distributed throughou...

BACKGROUND Parasite-specific IgE is thought to correlate with protection against Schistosoma mansoni infection or re-infection. Only a few molecular targets of the IgE response in S. mansoni infection have been characterised. A better insight into the basic mechanisms of anti-parasite immunity could be gained from a genome-wide characterisation of such S. mansoni allergens. This would have repe...

Helminths are parasitic organisms that can be broadly described as "worms" due to their elongated body plan, but which otherwise differ in shape, development, migratory routes and the predilection site of the adults and larvae. They are divided into three major groups: trematodes (flukes), which are leaf-shaped, hermaphroditic (except for blood flukes) flatworms with oral and ventral suckers; c...

Intestinal helminthic infections in Pemba Island, United Republic of Tanzania, have been perceived as a public health problem for many decades. School surveys in 1988 and 1992 and a community survey in 1991 were carried out to assess the distribution of prevalence and the intensity of these infections and to define the most effective strategy for control. The prevalence of helminthic infections...

Two polarized patterns (Th1 and Th2) of cytokines regulate inflammatory responses. Each cytokine pattern inhibits production of the opposing pattern. Lymphocytes from inflamed intestine due to Crohn's disease secrete a Th1 pattern of cytokines. Crohn's disease is most prevalent in highly industrialized countries with temperate climates. It occurs rarely in tropical third world countries with po...

Background: Asthma is less common in countries outside the organization for economic cooperation and development (OECD). One suggested mechanism for this disparity is the early life exposure to helminthic infection in non-OECD countries due to predominant Th1 immune response, which down-regulates Th2 responses required for exacerbation of asthma. This report is the first in the literature to de...
