Prevalence of Salmonella enterica in children aged less than 5 years with acute diarrhea and controls in Teresina-PI

Abstract

We investigated the prevalence of Salmonella enterica (SE) among children (n = 400/250 with diarrhea) in Teresina-PI from 2004 to 2007. SE Newport was isolated from two samples and O-C2-C3-ND, Enteritidis, and Muenchen serological variants were isolated from one sample each. SE infection was more prevalent among children aged less than six months. Increased fecal volume, 3-10 evacuations/day, vomit and fever were reported for all cases. Resistance to nalidixic acid (NAL) and sulphamethoxazole-trimethoprim (SXT) was ubiquitous. Our data substantiate the need for monitoring SE infections worldwide and the emergence of antimicrobial resistance.
