Tracking infectious bacteria from raccoons via rivers to humans with DNA

Researchers investigated the prevalence of an emerging foodborne disease-causing bacterium in wild raccoons and environmental water. They found genetic similarities between the strains found in both, suggesting possible transmission between wildlife and water. Genomic analyses of samples taken from the raccoons showed that many strains found in the animals carried virulence genes associated with diarrhea outbreaks in humans.
