Exploring the genomic and antimicrobial resistance tapestry: comparative insights into <i>Salmonella enterica</i> serotypes Agona, Braenderup, Muenchen, and Panama in Latin American surface waters.

ABSTRACT: Surface waters function as ecological niches where Salmonella enterica can persist and disseminate to fresh produce production systems. We examined the genomic characteristics of S. enterica serotypes Agona (n = 86), Braenderup (n = 47), Muenchen (n = 53), and Panama (n = 69) isolates from surface waters in Chile, Mexico, and Brazil between 2019 and 2022. Mexican isolates consistently displayed a higher occurrence of genotypic antimicrobial resistance (AMR) than Chilean and Brazilian isolates. All S. Agona isolates exhibited the presence of fosA7.2, while qnrB19 emerged as the predominant AMR gene (ARG) among S. Braenderup isolates. S. Muenchen isolates from Chile displayed an absence of any ARGs, while those from
