Description
Summary:The present study aims to determine the prevalence of Salmonella sp. in pigs in slaughterhouses under Federal Inspection at Mato Grosso, Brazil. Samples of mesenteric lymph nodes and tonsils were collected in three abattoirs from different regions. Three hundred samples were processed; fifty (16.6%) were positive for Salmonella sp. and belonged to fourteen different serological types. The most common serotypes were Derby (16%), Typhimurium (14%), London (12%) and Give (12%). The epidemiological results obtained show a low prevalence of this bacterium when compared to studies in other Brazilian states. Key words: Salmonella, swine, Mato Grosso.
