Therapeutic efficacy of ofloxacin, ciprofloxacin and NY-198 in experimentally infected normal and alloxan-induced diabetic mice.
The therapeutic efficacy of ofloxacin, ciprofloxacin and NY-198 was compared in alloxan-induced diabetic mice with experimental respiratory and urinary tract infections. Respiratory infection due to Klebsiella pneumoniae DT-S was well controlled by treatment with all compounds tested both in normal and diabetic mice. Similar observations were made in a model of urinary tract infection due to Serratia marcescens T-55. There was no difference between normal and diabetic mice in therapeutic efficacy of these compounds. They appear to be highly active antibacterial drugs in vitro under conditions which stimulate normal and diabetic states. There was no difference between normal and diabetic mice in the serum, lung and kidney concentrations. These observations suggest that ofloxacin, ciprofloxacin and NY-198 may be effective drugs in the treatment of bacterial respiratory and urinary tract infections which may occur in diabetic conditions.
