[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.

Adjustment of cephaloridine (Keflodin): dosage according to its pharmacokinetics.

The determination of the serum and urine concentrations of cephaloridine permitted calculation of the pharmacokinetic constants of this antibiotic: after administration of a 1-gram intravenous dose in five normal subjects; after administration of a 1-gram intramuscular dose in five normal subjects, five patients with renal impairment and five patients on maintenance hemodialysis. In normal subjects, serum half-life averaged 1.56 h (Ke=0.
