Abstract
Infection with Salmonella spp. it is a major cause of morbidity and mortality worldwide. Acute enteritis is the most common form of presentation and is generally self-limiting. The objective in this study to determine which are the sociodemographic, clinical and microbiological characteristics of the patients with isolation of Salmonella spp. in stool culture. This is a retrospective descriptive observational study that was conducted from January 1, 2016 to March 31, 2018 at the Fundación Clínica Infantil Club Noel, in patients older than 1 month and younger than 18 years with isolation of Salmonella spp. in stool culture. As results that were obtained in 55 cases were found; isolation was more frequent in infants, the predominant symptom was diarrhea and the initiation of ampicillin treatment was considered in most cases. Stool cultures were interpreted in (45.5%) and the most used directed treatment was ceftriaxone. A predominance of Salmonella spp. with Amp C resistance pattern and a high specific resistance to ampicillin: 76.4%. Infants were the most affected group according to what was reported in the literature. The symptoms were key to define the diagnosis and the start of the antibiotic. An increase in resistance to beta-lactams was observed in the susceptibility profiles. Salmonella should be considered in the differential diagnosis of ADE associated with fever. Antibiotic overuse was observed despite the recommendations focusing on support management. Resistance rates in the present study were high compared to the latest national registries.
