CDC: Increased incidence of resistant Salmonella infections

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

In a study published in Emerging Infectious Diseases, the researchers estimated a 40% increase in the annual incidence of nontyphoidal Salmonella infections with clinically important resistance in 2015-2016 compared with 2004-2008. When extrapolated to the entire US population, that amounts to roughly 63,000 more infections a year caused by antibiotic-resistant Salmonella.
During 2015–2016, the mean annual incidence was 2.38 (95% CrI 1.93–2.86)/100,000 persons for clinically important resistant infections and 1.83 (95% CrI 1.45–2.25)/100,000 persons for MDR infections. The 5 major serotypes (Enteritidis, Typhimurium, Newport, I 4,[5],12:i:-, and Heidelberg) accounted for 69% of infections with clinically important resistance and 66% with multidrug resistance.
