Canine leptospirosis in New Jersey and Michigan: 17 cases (1990-1995).

Abstract

The clinical, laboratory, and serological findings in 17 dogs with disease resulting from leptospiral infection were evaluated retrospectively. Acute renal failure was the most common syndrome, but cholestatic hepatic disease also was common. The most prevalent serovars identified were pomona, grippotyphosa, and autumnalis. Paired serology was available on 10 dogs. Aggressive fluid therapy in combination with ampicillin or amoxicillin resulted in a good survival rate. Canine leptospirosis may be more common than suspected, and paired serology often is necessary to confirm a diagnosis.
