Outbreak of Uncommon O4 Non-Agglutinating Salmonella Typhimurium Linked to Minced Pork Saxony-Anhalt Germany January to April 2013

摘要

IntroductionIn January 2013, the National Reference Centre for Salmonella (NRC) detected a salmonellosis cluster in Saxony-Anhalt, Germany, caused by uncommon O4 non-agglutinating, monophasic Salmonella (S.) Typhimurium DT193. Circulating predominant monophasic S. Typhimurium DT193 clones typically display resistance phenotype ASSuT. We investigated common exposures to control the outbreak, and conducted microbiological investigations to assess the strains’ phenotype.
