Specimens Blood, blood clot, bone marrow, and stool are common speci-mens used for isolation of typhoidal bacilli for culture. We report on three cases of laboratory-acquired Salmonella enterica serotype Typhi (Salmonella Typhi) infection which occurred over the period 2012 to 2016 in South Africa. But infection by non-typhoid salmonellae is much more common and usually causes gastroenteritis, with symptoms including diarrhoea, abdominal pain, nausea and vomiting lasting from 1-7 days. Serological tests based on agglutination methods can also be used for diagnosis of Salmonella infection. Author W D Foster.
