Foodborne Diseases (FBD) are caused by ingesting food or water polluted with specific etiological agents as bacteria, and characterized by gastroenteritis. In acute case are presented as hemolytic whole diseases producing the host's death. In America the FBD affects about 77 million people, where more than 12,000 die per year. Even when, was observed that the 95% of demises are due to E. coli and Salmonella, the number of people affected cannot be accurately determined because many of this are not notified, we initiate an epidemiological study in our region to determine the pathogen causing FBD. We isolated and characterized strains from stool cultures samples, during 2013-2016 periods, from Header Hospitals of Tucuman and Santiago del Estero. Here, 1543 strains were isolated from pediatric patients. We observed that during the 2015/2016 summer period more cases of FBD were recorded. The suspicious strains were then analyzed by biochemical and serology tests to classify the pathogens. We observed that 10% of it belonged to Salmonella sp, while the remaining 90% were identified as Shigella, many of these were presented as antibiotic multi-resistant strains. Our data suggest that Shigella is the pathogen prevalent in the NOA and that in the Tucuman´s population the gastroenteritis cases are more frequently caused by the Salmonella as pathogens.
