Helminths modulate both the adaptive and innate arms of human immune system. Such immune alteration seems to have an anti-inflammatory effect. Chronic helminth infections switch the immune response from Th1 to Th2 by various mechanisms and by different helminth derived molecules. Though these immunological responses provide a survival advantage, they seem to hamper the response to non-helminth ...

Heligmosomoides polygyrus (formerly known as Nematospiroides dubius, and also referred to by some as H. bakeri) is a gastrointestinal helminth that employs multiple immunomodulatory mechanisms to establish chronic infection in mice and closely resembles prevalent human helminth infections. H. polygyrus has been studied extensively in the field of helminth-derived immune regulation and has been ...

Background The effect of helminth infections on allergic diseases is still inconclusive. Several studies show that Treg cell induced by parasites down regulate the host Th2-mediated allergic response. However, some studies highlight the importance of alternative activated macrophages (AAM) in the pathogenesis of allergic diseases. This phenotype is also implicated in helminth survival. Our aim ...

A parasitologic survey of human parasitic infections was made in Shizuoka Prefecture, Japan, during August and September, 1950 (Ritchie et al., 1951a). The objectives included a determination of (i) the incidence of infections, (ii) helminth densities,(iii) factors predisposing infections,(iv) the status of schistosomiasis,(v) status of paragonimiasis and filariasis, and (vi) the efficiency of ...

background: intestinal parasitic infections have a worldwide distribution. high prevalence of intestinal parasitic infections in individuals with low socioeconomic status and environmental conditions was found. no study has ever been conducted on the prevalence of these infections in jiroft. therefore, in this study prevalence of intestinal parasitic infections was evaluated in jiroft, kerman p...

OBJECTIVE To estimate the degree of synergism between helminth species in their combined effects on anemia. METHODS Quantitative egg counts using the Kato-Katz method were determined for Ascaris lumbricoides, hookworm, Trichuris trichiura, and Schistosoma japonicum in 507 school-age children from helminth-endemic villages in The Philippines. Infection intensity was defined in three categories...

BACKGROUND Zoonotic infections are among the most common on earth and are responsible for over 60% of human infectious diseases, some of which are caused by helminth parasites. Infection may result from ingestion of infective stage of worms with food, contaminated soil; skin penetration or direct animal contact. This study estimates the prevalence of zoonotic helminth infections (ZHI) among ani...

Helminths are parasitic nematodes and trematodes, grouped together because of morphological similarities and commonalities in the effects infections have on hosts. These include complications such as anemia and biasing of immune responses, which can alter susceptibility for other diseases. For pregnant women, these complications might have implications for pregnancy outcomes or neonatal health....

Co-infection may affect transmission and recovery from infection, but remains an understudied element of disease ecology, particularly with regard to antagonism between parasites sharing a host. Helminth and giardia infections are often endemic in the same populations and both occupy the small intestine; yet few studies have examined interactions between these parasites. We report on helminth-g...
