ARS scientists have found that an antibiotic-resistant strain of Salmonella becomes especially virulent when tucked inside protozoa in the rumen, or first stomach, of cattle. Protozoa are one-celled predatory organisms that engulf and destroy most bacteria.

This breakthrough finding at ARS's National Animal Disease Center (NADC) in Ames, Iowa, represents the first time that disease-causing bacteria have been found to gain strength from interaction with protozoa inside an...
