Epidemiology of Salmonella in two different finishing swine barns in Brazil
Carvalho, Luiz Fernando
Many finishing barns in Brazil have "lamina d'agua", a continuous water flow at the back of solid-floored adjacent pens. Prevalence of Salmonella shedding and environmental contamination in finishing barns with "lamina d'agua" and without it were assessed through a cross sectional study conducted in 6 farms. No difference was found between the two systems. Sixteen Salmonella strains were isolated from 4 farms, comprising 6 serotypes: S. Agona, S. Typhimurium, S. Senftenberg, S. Sandiego, S. Rissen and S. Javiana. Serotypes varied among farms and differed from those recently identified in Brazil. Epidemiology of salmonella in swine farms is complex and might vary between farms or even between barns in a same farm.
