Clinical Update: Vaccinating Against Canine Leptospirosis

Despite the ubiquitous nature of leptospires, their zoonotic potential, and widespread vaccination in dogs and cattle, leptospirosis can be considered an emerging disease. We have incomplete knowledge of the epidemiology of leptospirosis. There is a changing pattern in serovar prevalence driven by vaccination, geography and the distribution of reservoir hosts, and reports of clinical disease in vaccinated individuals. This review examines our current knowledge of this disease, its epidemiology, what vaccinations are currently available and the science behind which preparation we should choose.
