Assessing Risk Profiles for Salmonella Serotypes in Breeding Pig Operations in Portugal
New research from Portugal reveals that the prevalence of herds with breeding pigs that had at least one sample positive to serotype Typhimurium or S. Typhimurium-like strains with the antigenic formula: 1,4,5,12:i: was 13.8 per cent, and for the other serotypes, prevalence was 31.7 per cent. The risk factors for Typhimurium suggest a contagious pattern and the risk factors for other serotypes appear were more closely related to environmental factors.
