Gentamicin resistance in Christchurch hospitals.

Prior to June 1976, the isolation of gentamicin resistant organisms was an infrequent occurrence in North Canterbury Hospital Board institutions. During July 1976, 20 different gentamicin resistant organisms were isolated from patients in Christchurch Hospital. Gentamicin resistant organisms hav e been continually isolated from an increasingly wide area since then. The organisms involved are: providence species; Pseudomonas aeruginosa; Klebsiella species; E coli; Staphyloccus aureus; Proteus mirabilis; Staphylococcus epidermidis; Acinetobacter species; Enterobacter species; Haemophilus influenzae; Pseudomonas maltophilia CDC II F; Citrobacter species; Alcaligenes odorans and Pseudomonas species. The spread of gentamicin resistant organisms has occurred rapidly in the hospital environment. The importance of the urinary tract as a reservoir of microorganisms is indicated in this report.
