Abstract

Salmonella enterica serovar Infantis is causing an increasing number of infections worldwide. Our aim was to describe the characteristics of S. enterica serovar Infantis among patients attended in a hospital of Lima, Peru. Fifty cases of salmonellosis were seen during October 2015-May 2017; Salmonella Infantis was detected in 36% (n = 18) of them, displacing Enteritidis and Typhimurium (n = 13, 26%, each). Seventeen cases caused by Salmonella Infantis were presented as diarrheal illnesses; only one extraintestinal case (bacteremia) was seen in a 1-year-old infant. This serovar is resistant to multiple groups of antimicrobials, showing only fully susceptibility to carbapenems. Compared with Infantis, other serovars analyzed (mainly Enteritidis and Typhimurium) showed a lower frequency of resistance to antimicrobials such as trimethoprim-sulfamethoxazole, ampicillin, and chloramphenicol. The antibiotic with the highest frequency of resistance was ciprofloxacin. Further studies are needed to evaluate the routes of transmission and measures of control of this multidrug-resistant Salmonella.
