Leptospirosis can be caused by infection with a number of different serovars of the bacteria Leptospira interrogans. In general infection with a host adapted strain results in subclinical infection, intermittent shedding of the organism and the animal acts as a reservoir for infection. Infection with non host adapted strains results in clinical disease.

***Serovars ''canicola'' and ''icterohaemorrhagica'' cause leptospirosis in dogs, but are vaccinated against

Vaccination against serovars ''canicola'' and ''icterohaemorrhagica'' has greatly reduced the prevalence and incidence of disease in the UK

 

***Serovars ''pomona'' and ''grippotyphosa'' are becoming important
