USA: Increased incidence of AMR nontyphoidal salmonella infections, 2004–2016

Emerging Infectious Diseases Vol 27, Number 6 - June 2021 13 June, 2021

The annual incidence of resistant nontyphoidal Salmonella infections was 40% higher in 2015 and 2016 compared with the years 2004 to 2008, according to a study published in Emerging Infectious Diseases. Salmonella is a major cause of foodborne illness in the United States, and antimicrobial-resistant strains pose a serious threat to public health. From 2004-2008 to 2015-2016, there was an estimated 40% increase in the annual incidence of Salmonella infections with clinically important resistance to any of three antimicrobial drugs recommended to treat severe infections. The increase translates to approximately 63,000 more resistant infections per year. The study also demonstrated that changes in incidence of resistance varied by serotype. Serotypes I 4,[5],12:i:- and Enteritidis were responsible for two thirds of the increased incidence of clinically important resistance during 2015–2016. Ciprofloxacin-nonsusceptible infections accounted for more than half of the increase.
