Resistance to antibiotics in gram-negative rods from clinical material of hospital and community origin.
The authors examined the resistance to 13 antibiotics and chemotherapeutic agents by the diluting micromethod and the routine disk method in the group of 5375 gram-negative strains of 7 genera which prevailed in clinical material of an hospital (FN Olomouc) and in material of community (OHS Olomouc) provenance during the years 1992 and 1993. In the majority of cases, the resistance was more frequent in the strains isolated from the hospital material. The most remarkable differences were found in A cinetobacter sp. (9-76%), Enterobacter sp. (10-60%) and Citrobacter sp. (18-58%). In other examined species, the differences varied in the ranges 3-40% in E.coli, 2-33% in Klebsiella sp., 0-28% in P. vulgaris, 2-28% in P.mirabilis, 0-16% in M.morganii, and 0-13% in P. aeruginosa.
