Prevalence of helminth infection was higher in the schools where hygiene conditions (ie, tapwater, handwashing soap) were lacking. (medscape.com)
While T H 2 responses limit helminth infection and can result in the physical expulsion from the mucosal membranes in which they reside, helminths are rarely killed. (biomedcentral.com)
For each of these studies, we qualitatively addressed the effects of helminth infection on within-individual (alpha) and between-individual (beta) fecal microbiome diversity, infection-associated microbial taxa, the effect of helminth clearance on microbiome composition, microbiome composition as a predictor of infection status or treatment outcome, and treatment-specific effects on the fecal microbiome. (nih.gov)
While safe and effective drugs can treat helminth infection, the rapid rise of anthelmintic drug resistance [ 6 ] necessitates development of new strategies for parasite control. (biomedcentral.com)
Helminth infection has emerged as one possible explanation for the low incidence of autoimmune diseases and allergies in less developed countries, while reduced infection rates have been linked with the significant and sustained increase in autoimmune diseases seen in industrialized countries.

This situation motivated us to update estimates of people at risk for the major foodborne trematodes, to quantify the changes in freshwater fish and crustacean production in the past 10-50 years in trematodiasis-endemic countries, and to examine the relationship between proximity of human habitation to freshwater bodies and infections with liver, lung, or intestinal flukes. (cdc.gov)
Finally, a random forest classifier accurately predicted a fish's exposure to the parasite based on the abundance of gut phylotypes, which underscores the potential for using the gut microbiome to diagnose intestinal parasite infection. (biomedcentral.com)

Giardia lamblia is a protozoan parasite that also commonly causes infection in these settings. (refugeehealthguide.org.au)

Further, the low prevalence of allergic disease in the rural Tropics has been attributed to the immune modulatory effects of these infections and there is concern that widespread use of anthelmintic treatment in high-risk groups may be associated with an increase in the prevalence of allergic diseases. (biomedcentral.com)

Because the most widely used vaccines are administered during the first year of life and the antecedents of allergic disease are considered to occur in early childhood, the present study has been designed to investigate the impact of early exposures to geohelminths on the development of protective immunity to vaccines, allergic sensitization, and allergic disease. (biomedcentral.com)
Primary study outcomes are the development of protective immunity to common childhood vaccines (i.e. rotavirus, Haemophilus influenzae type B, Hepatitis B, tetanus toxoid, and oral poliovirus type 3) during the first 5 years of life, the development of eczema by 3 years of age, the development of allergen skin test reactivity at 5 years of age, and the development of asthma at 5 and 8 years of age.
