Wild strains of salmonella find a backdoor entry into plants

As the world wrestles with the coronavirus (COVID-19) pandemic, which arose after the virus jumped from an animal species to the human species, University of Delaware researchers are learning about new ways other pathogens are jumping from plants to people.

Foodborne titanium dioxide nanoparticles impact gut microbiota in mice

A common food additive, recently banned in France but allowed in the U.S. and many other countries, was found to significantly alter gut microbiota in mice, causing inflammation in the colon and changes in protein expression in the liver, according to research led by a University of Massachusetts Amherst food scientist.

New approach spurs production of antibiotic or antiparasitic compounds in bacteria

Researchers have developed a method to spur the production of new antibiotic or antiparasitic compounds hiding in the genomes of actinobacteria, which are the source of drugs such as actinomycin and streptomycin and are known to harbor other untapped chemical riches.
