TY - JOUR T1 - Disentangling outbreaks using whole-genome sequencing: concurrent multistate outbreaks of Salmonella Kottbus in Germany, 2017 AU - Enkelmann, Julia AU - von Laer, Anja AU - Simon, Stéphanie AU - Fruth, Angelika AU - Lachmann, Raskit AU - Michaelis, Kai AU - Borowiak, Maria AU - Gillesberg Lassen, Sofie AU - Frank, Christina AB - In June 2017, an outbreak of Salmonella Kottbus infection was suspected in Germany. We investigated the outbreak with whole-genome sequencing (WGS) and a case–control study. Forty-six isolates from 69 cases were subtyped. Three WGS clusters were identified: cluster 1 (n = 36), cluster 2 (n = 5) and cluster 3 (n = 3). Compared to controls, cluster 1 cases more frequently consumed raw smoked ham (odds ratio (OR) 10, 95% confidence interval (CI) 1.2–88) bought at supermarket chain X (OR 36, 95% CI 4–356; 9/10 consumed ham Y). All four cluster 2 cases interviewed had consumed quail eggs. Timely WGS was invaluable in distinguishing concurrent outbreaks of a rare Salmonella serotype.
