Abstract
Gentamicin was administered parenterally for 6 days to 43 dogs with urinary tract infections. The daily dosage of 6.6 mg/kg (3 mg/lb) was divided into equal parts and given IM or SC at 8-hour intervals. Dogs selected for treatment with gentamicin had urinary infections that had not responded to treatment with other antimicrobial agents or had bacterial isolates from urine that were resistant to several antimicrobial agents on in vitro susceptibility tests. Response to treatment, defined as negative urine culture on the last day of therapy or 4 to 14 days after completion of the therapeutic course, included 20 of 22 (91%) infections caused by Escherichia coli, 8 of 9 (89%) infections caused by Kebsiella pneumoniae, 6 of 7 (86%) infections caused by Proteus spp, and 6 of 7 infections caused by Pseudomonas spp. These four species comprised 84% of the bacteria isolated from the dogs in this study.
