Bakteriaemi forårsaget af zoonotiske Salmonella-typer i Storkøbenhavn 1984-1988

: The five departments of clinical microbiology in Greater Copenhagen have together carried out a retrospective review of bacteraemia caused by the zoonotic Salmonella serotypes in the period 1984-1988 in the municipalities of Copenhagen and Frederiksberg and in the County of Copenhagen. A gradual increase in frequency was observed from 11 cases in 1984 to 58 cases in 1988. The serotype most commonly isolated was Salmonella dublin followed by Salmonella enteritidis and Salmonella typhimurium. S. dublin was found to be more invasive and more virulent than the other serotypes. Predisposing factors were present in 56% of the patients; the commonest of these was malignant disease. Fatal or complicated course of the disease were observed more frequently in predisposed patients than in persons who had previously been healthy. A total of 17% of the patients died and one fourth of these had ruptured aortic aneurysm probably on account of Salmonella arteritis. 20% developed recurrence of bacteraemia while in the remaining patients the disease ran an uncomplicated course. It is concluded that the marked increase in the number of cases and the serious course taken by the infection demonstrate a definite need for increased prophylactic efforts in the food industry.
