Analysis of PFGE profiles of Salmonella Typhimurium and S. Derby isolated from pigs in France

An European baseline study was carried out in 2006-2007, 86 isolates of Salmonella Typhimurium (ST) and 75 of S. Derby (SD) were isolated from the ileo-caecal and mesenteric lymphatic ganglia of pigs, and serological results for these pigs were obtained from meat juice The aims of this study were to analyze the genetic diversity within these two serovars, the geographical and seasonal distribution of the genotypes, and to test a link between genotype isolated from a pig and the level of seroconversion in the same pig
