By looking at the exposure to the parasitic roundworm Ascaris lumbricoides/suum in Nothern Europe (Norway, Denmark and Estonia), the study finds that younger men exposed to Ascaris had a striking reduction in lung function and nearly five times higher odds of having asthma compared to the non-exposed.
Researchers at Washington University School of Medicine in St. Louis have received two grants from the National Institutes of Health totaling more than $5.5 million to develop new treatments for two types of devastating parasitic infections common in sub-Saharan Africa and Central and South America: river blindness and intestinal worm infections.
A mother's response to stress can even influence her grandchildren. Biologists at the University of Iowa found that roundworm mothers subjected to heat stress passed, under certain conditions and through modifications to their genes, the legacy of that stress exposure not only to their offspring but even to their offspring's children.
