[Epidemiology and prevention of leptospirosis in dogs]

Leptospirosis is a zoonotic disease with increasing prevalence in dogs and humans. The various Leptospira serovars display different pathogenicity. Even healthy infected dogs can shed leptospires with their urine and thus, represent a risk for humans and other animals. Vaccination is the most important measure for prevention; it not only prevents disease in dogs, but also reduces shedding of leptospires in urine. For comprehensive protection through vaccination, tetravalent vaccines containing serovars of the serogroups relevant in the corresponding region should be used. The spread of the pathogen can be reduced by a wide application of these vaccines. A detailed owner education about the zoonotic potential of the infection and appropriate hygiene measures when handling the infected dog and its urine are essential.
