Leptospirosis in Twenty Dogs and Two Foxes

Abstract

From January in 2002 through January in 2004 twenty domestic dogs and wild two foxes in Okayama and Tottori Prefecture referred to or sheltered in our hospitals were diagnosed with leptospirosis, based on the clinical signs, complete blood count, blood tests, and serological measurement of titers of antibody to Leptospira. Nineteen dogs had not had the necessary vaccinations. Clinically all the animals suffered from anorexia and weakness. Almost all suffered from vomiting and neurosis, probably caused by azotemia. Blood tests revealed severe renal failure and hepatic insufficiency. These infected animals were found not only in remote areas surrounded by mountains but also in towns, which may indicate a threat of wide prevalence of leptospirosis among both wild and domestic animals. So we need to establish more correct diagnosis and effective treatment, and to inform pet owners to take precautions such as vaccinations.
