Antimicrobial profile of non-typhoidal Salmonella isolated from raw sewage in the Metropolitan Region of São Paulo, Brazil.

Introduction: Non-typhoidal Salmonella (NTS), are frequently found in sewage and are one of the main causes of diarrhea in developed and developing countries due to poor sanitation conditions. In addition, NTS can potentially act as reservoirs and vehicles for the transmission of antimicrobial resistance (AMR), which can be facilitated by the discharge of sewage effluents into environmental matrices. This study aimed to analyze a NTS Brazilian collection, focusing on their antimicrobial susceptibility profile and the presence of clinically relevant AMR-encoding genes.
