Trends in antimicrobial susceptibility of salmonella recovered from cattle diagnostic samples in Ohio

Abstract

 Salmonella enterica is an important cause of illness and death in humans. There has been a great deal of efforts to reduce its impact; yet Salmonella infections continue to burden the health of U.S. consumers more than any other foodborne pathogen. Salmonellosis is also an important cause of disease in cattle, causing diarrhea, dehydration, depression, fever, decreased milk production, and anorexia. Surveillance for antimicrobial resistance within healthy food animal populations captures predominantly susceptible Salmonella serovars that are infrequent causes of human illness; however, data from cattle diagnostic submissions can be used to capture trends in antimicrobial susceptibility of strains with a higher public health relevance. Our objective was to evaluate trends in antimicrobial susceptibility of Salmonella recovered from diagnostic samples from clinically ill cattle submitted to the Ohio Department of Agriculture between 2006 and 2017.
