An increase in cases of Salmonella typhimurium sequence type 36 is being investigated.
From August to October, 81 cases from 18 regions have contracted Salmonella typhimurium of sequence type 36 (ST 36). The cases, which have all been infected in Sweden unless information about the country of infection is missing, are infected with one of about ten different genetically related bacterial variants that have caused cases of illness from August to October (figure).
During September 2024, an outbreak investigation of cases infected with a specific variant of Salmonella Typhimurium of the ST 36 type was initiated.
