Clinical outcomes in cases of foodborne salmonellosis are significantly worse when the pathogen of infection exhibits any antimicrobial resistance (AMR), according to recent research from the U.S. Centers for Disease Control and Prevention (CDC). However, infections caused by Salmonella with resistance only to clinically important antibiotics were not associated with poorer outcomes, suggesting that factors other than treatment failure—such as strain virulence, strain source, and host factors—may be important.
According to CDC, nontyphoidal Salmonella causes an estimated 1.35 million infections in the U.S. annually. AMR is recognized as one of the greatest emerging threats to global public health by national and international agencies.
