Multidrug-Resistant Salmonella

JAMA. 2019;322(14):1344. doi:10.1001/jama.2019.15309

Researchers have identified a new strain of foodborne multidrug-resistant Salmonella with resistance to ciprofloxacin and reduced susceptibility to azithromycin, warned a recent CDC report.

The CDC first identified the multidrug-resistant strain Salmonella enterica serotype Newport in September 2018 during an outbreak investigation. “Decreased susceptibility to azithromycin has been rare among nontyphoidal Salmonella that cause human infections in the United States,” said the report’s senior author Cindy Friedman, MD, an epidemiologist in the CDC’s Enteric Diseases Branch in an email.
