Parasitic nematodes show levels of genetic diversity comparable to other taxa, but the functional consequences of this are not understood. Thus, a large body of theoretical work highlights the potential consequences of parasite genetic diversity for the epidemiology of parasite infections and its possible implications for the evolution of host and parasite populations. However, few relevant emp...

Diarrhea is the manifestation of gastrointestinal infection and is one of the major causes of mortality and morbidity specifically among the children of less than 5 years age worldwide. Moreover, in recent years there has been a rise in the number of reports of intestinal infections continuously in the industrialized world. These are largely related to waterborne and food borne outbreaks. These...

BACKGROUND Neglected tropical diseases continue to be one of the leading causes of morbidity and mortality in the developing world. Psychiatric patients are among groups at risk for parasitic infection although control and monitoring programs largely overlook this population. This study aimed at determining prevalence and factors associated with intestinal parasitic infection among patients adm...

Whether parasitic diseases-and in particular helminth infections because they are extensive and widespread-have an effect on mental functions and educational attainment is by no mean a new question. Concern about the possibility was evident in the early decades of the century, and the results of investigations designed to discover whether the effects of parasite infections had consequences on s...

BACKGROUND Parasitic nematodes are one of the most important causes of production losses in most cattle-producing countries of the world. The aim of the present study is to make a through estimate of helminth and protozoan infection prevalence in dairy cattle around Taiwan. METHODS Coprological techniques, including direct fecal smear, simple flotation, and simple sedimentation, were used to ...

Eosinophilic leukocytes function in host protection against parasitic worms. In turn, helminthic parasites harbor specific molecules to evade or paralyze eosinophil-associated host immune responses; these molecules facilitate the migration and survival of parasitic helminths in vivo. This competition between eosinophil and worm leads to stable equilibria between them. An understanding of such d...

Intestinal parasitic infections are among the most common infections world-wide.(Kang G et al 1998) Intestinal parasitic infection varies considerably from place to place in relation to the disease.(Luka SA et al 2000) According to the World Health Organization estimate; globally two billion individuals are infected with intestinal parasites(WHO 2002) and there are 800-1000 million cases of Asc...

Parasites, which are a recently discovered yet ancient dweller in human hosts, remain a great public health burden in underdeveloped countries, despite preventative efforts. Rheumatoid arthritis is a predominantly cosmopolitan health problem with drastic morbidity rates, although encouraging progress has been achieved regarding treatment. However, although various types of methods and agents ha...

The Quetelet index, hemoglobin and parasitic infection rates of adolescent and young women from 21 villages in Northeast Thailand were assessed. Data were collected in the hot, rainy and cold seasons of the year. The proportion of undernourished females varied between 10 and 15% when a cut-off point of 18.7 of the Quetelet index was chosen. 23 to 33% of the women had hemoglobin levels below 12 ...
