Intestinal helminth infections during pregnancy are associated with adverse outcomes including low birth weight and prenatal mortality. The infections are a major public health problem in developing countries. A hospital based survey was undertaken for six months to determine the infection prevalence, intensity, and risk factors. The study involved expectant women attending antenatal clinic. St...
Background Malaria and helminths share the same geographical distribution in tropical Africa. Studies of the interaction of helminth and malaria co-infection in humans have been few and are mainly epidemiological, with little information on cellular immune responses. This study aimed to determine Cytokine profiles among patients co-infected with Plasmodium falciparum malaria and soil borne helm...
red foxes and golden jackals are the two most abundant wild carnivores of iran which have the ability to adopt a variety of habitats and human proximity. despite this, very few investigations on their helminth and none on their external parasites infections have been carried out in iran. between 2003 and 2004, a total of 79 jackals and 37 foxes were collected from 3 different climatic zones of ...
Intestinal helminth infections may reduce nutrient availability and thereby impair cognitive growth and other functions. Certain nutrients such as fatty acids may also modulate inflammation and the immune response and, thus, the severity of helminth infection. Fatty acid status may, therefore, both be affected by and affect helminth infection. Rural school-children in South Africa with a 35% he...
Helminth parasites infect over one fourth of the human population and are highly prevalent in livestock worldwide. In model systems, parasites are strongly immunomodulatory, but the immune system can be driven to expel them by prior vaccination. However, no vaccines are currently available for human use. Recent advances in vaccination with recombinant helminth antigens have been successful agai...
The Global Burden of Disease caused by the 3 major intestinal nematodes is an estimated 22.1 million disability-adjusted life-years (DALYs) lost for hookworm, 10.5 million for Ascaris lumbricoides, 6.4 million for Trichuris trichiura, and 39.0 million for the three infections combined (as compared with malaria at 35.7 million) (World Bank, 1993; Chan et al. 1994); these figures illustrate why s...
Helminth is a nonphylogenetic term that refers to multicellular animals (or metazoans) that have adopted a parasitic lifestyle in mammalian hosts. They are more commonly referred to as parasitic worms. These worms generally (with the exception of Strongyloides stercoralis) cannot replicate within the host, and they have evolved distinct methods to co-exist with their host through the activation...
BACKGROUND Intestinal helminth infections are major parasitic diseases causing public health problems in Ethiopia. Although the epidemiology of these infections are well documented in Ethiopia, new transmission foci for schistosomiasis are being reported in different parts of the country. The objective of this study was to assess the prevalence of Schistosoma mansoni and other intestinal helmin...
Approximately one-third of the world's population suffers from chronic helminth infections with no effective vaccines currently available. Antibodies and alternatively activated macrophages (AAM) form crucial components of protective immunity against challenge infections with intestinal helminths. However, the mechanisms by which antibodies target these large multi-cellular parasites remain obs...
