[Utility of serotyping in the study of Serratia marcescens infections in Strasbourg Hospitals (author's transl)].

A total of 1,499 Serratia marcescens strains were isolated in Strasbourg University Hospital within a period of three years. Serotyping could split this collection into 37 different serotypes. Two serotypes (014:H12 and 013:H17) were responsible for a persistent S. marcescens endemic. Serotype 014:H12 was mostly recovered from sputa, whereas serotype 013:H17 was mostly recovered from urine. These two serotypes had different antibiotic resistance patterns.
