Leptospirosis is an important zoonosis, affecing humans as well as animals. The disease 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 with the animal acting as a reservoir for infection. Infection with non host adapted strains results in clinical disease.

Transmission is via urine of affected animals; the organism gains entry at mucous membranes, broken skin, bite wounds and through ingestion of infected material . The organism can remain viable for weeks in damp conditions

Transmission is via urine of affected animals; the organism gains entry at mucous membranes, broken skin, bite wounds and through ingestion of infected material. The organism can remain viable for weeks in damp conditions, rodents and other mammals act as a reservoir of infection. The incubation period is 2-12 days
