Roundworm News and Research

RSS

Roundworm infection, or toxocariasis, is a zoonotic disease — a disease that can be transmitted from animals to humans. Dogs and cats are the definitive hosts for the roundworm species that commonly cause human disease.

Deep learning software helps to identify miniscule bacteria in microscopy images

Advanced gene therapy may prevent severe loss of muscle mass in elderly people

Researchers at NTNU have managed to restore muscle function in older mice with muscle loss using advanced gene therapy. The hope is that this method might eventually be used on humans to prevent severe loss of muscle mass.

Exposure to parasitic roundworm linked with lower lung-function and asthma in younger men

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 receive NIH grants to develop new treatments for neglected tropical diseases

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.

Genome sequencing efforts overlook huge swathes of diversity and opportunity, researchers warn

Efforts to sequence the genomes of the world's animals tend to focus on those that most resemble humans with the work conducted almost entirely in the Global North, according to an analysis led by Washington State University.

Mothers pass on the legacy of stress exposure to future generations

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.

Researchers discover unique self-destructive process in aging nematode worms

As worm mothers age, they secrete a milk-like fluid through their vulva that is consumed by their offspring and supports their growth, according to a new study led by UCL researchers.

Drug accumulation alters gut bacterial metabolism and composition

In a research paper recently published in the journal Nature by Klünemann et al. (September 8th, 2021), the interaction of 15 diverse drugs with 25 common strains of gut bacteria is investigated, revealing 70 bacteria-drug interactions that include 29 entirely novel mechanisms not yet reported.

Anti-parasitic drug prevents pancreatic cancer's initiation, progression and metastasis in mice

As the third-most lethal cancer in the United States, with only a 1% five-year survival rate for people with its most aggressive form, pancreatic cancer has long been a target of researchers who search for ways to slow or stop its growth and spread.
