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

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.
