A new study from the Mitreva lab sheds light on the relationship between the liver fluke Fasciola hepatica and its bacterial endosymbiont, Neorickettsia. Researchers found that while these bacteria are widely present in fluke populations across the Americas and Europe, they show low genetic diversity and strong geographic patterning. Their results suggest a complex evolutionary history shaped by […]

The bacteria enterotoxigenic E. coli and Shigella together cause hundreds of millions of infections each year and are among the leading causes of diarrheal death, especially in children. New research from Washington University School of Medicine in St. Louis points to a shared biological feature of these gut pathogens that could lead to a vaccine that protects against both.

Hookworms, intestinal parasites that infect hundreds of millions of people in under-resourced tropical regions around the globe, have evolved to survive inside the human gut for years, secreting molecules that enable co-existence with their hosts. Now, researchers at Washington University School of Medicine in St. Louis have harnessed that biological mechanism for potential human benefit, […]

WashU Medicine infectious diseases researchers have developed a practical use of artificial intelligence to enhance patient safety, while potentially reducing costs and improving efficiency at hospitals. Abby Sung, MD, an assistant professor of medicine, and colleagues in the Division of Infectious Diseases, WashU McKelvey School of Engineering AI for Health Institute, and Barnes-Jewish Hospital (BJH) found that a large language model (LLM) can strengthen a semi-automated surveillance tool used by infection prevention. Dr. Sung, the primary investigator of the study, said the goal was to see if mandatory infection surveillance process could be […]
