Background: Salmonella enterica subsp. enterica serovar Saintpaul (antigenic formula 1,4,[5],12:e,h:1,2) is a serovar of the O:4 (B) serogroup.
Reports of Reports of S. Saintpaul have increased recently, these reports have found that turkeys and ground turkey are important sources of S. Saintpaul. In addition, in several countries, S. Saintpaul have caused large outbreaks associated with produce (e.g., cucumbers, alfalfa sprouts, peppers). In Germany, a clonal line with a multidrug resistant phenotype was found in turkeys and human feces. This strain showed resistance to β-lactam antibiotics, aminoglycosides, nalidixic acid, and sulfamethoxazole, along with intermediate resistance to ciprofloxacin and third-generation cephalosporins.
