| Summary: | <i>Salmonella</i> is one of the most important food borne zoonotic pathogens. While mainly associated with poultry, it has also been associated with pigs. Compared to the high-income countries, there is much less known on the prevalence of <i>Salmonella</i> in low- and middle-income countries, especially in the Caribbean area. Therefore, we investigated the prevalence of <i>Salmonella</i> in pigs and pig meat in Suriname. A total of 53 farms and 53 meat samples were included, and <i>Salmonella</i> was isolated using standard protocols. Strains were subjected to whole genome sequencing. No <i>Salmonella</i> was found on pig meat. Five farms were found to be positive for <i>Salmonella</i>, and a total of eight different strains were obtained. Serotypes were <i>S.</i> Anatum (<i>n</i> = 1), <i>S.</i> Ohio (<i>n</i> = 2), a monophasic variant of <i>S.</i> Typhimurium (<i>n</i> = 3), one <i>S.</i> Brandenburg, and one <i>S.</i> Javaniana. The monophasic variant of <i>S.</i> Typhimurium belonged to the ST34 pandemic clone, and the three strains were very similar. A few resistance genes, located on mobile genetic elements, were found. Several plasmids were detected, though only one was carrying resistance genes. This is the first study on the prevalence of <i>Salmonella</i> in pigs in the Caribbean and that used whole genome sequencing for characterization. The strains were rather susceptible. Local comparison of similar serotypes showed a mainly clonal spread of certain serotypes. |
