<i>Salmonella</i> in pigs slaughtered in Ecuador: prevalence, serotypes, genotypes and antibiotic resistance.

ABSTRACT: Salmonella enterica subsp. enterica (S. enterica) is a leading foodborne pathogen worldwide, and pork products are major sources of infection. Given the lack of data on S. enterica infection in pigs slaughtered in Ecuador, this study aimed to determine its prevalence, as well as the serotypes, genotypes and antimicrobial susceptibility profiles of isolates from cecum contents (CCs) and mesenteric lymph nodes (MLNs) sampled from 365 pigs at the evisceration step at a slaughterhouse in Quito city. Salmonella spp. in the samples was detected by culture (ISO 6570-1 method). Strains were serotyped (ISO 6579-3 method), tested for antimicrobial susceptibility using the disk diffusion method, and genotyped by macrorestriction of chromosomal DNA. Salmonella ent
