'''Leptospirosis''' is an infective disease caused by the bacteria [[Leptospira]]. There are a number of serovars of the bacteria which vary in their pathogenesis and host specificity. ''L. bratislava'' and ''L. pomona'' are both host adapted to swine and are the most common cause of clinical leptospirosis in pigs. Other serovars which are host adapted to other species can also cause disease in pigs: ''L. icterohaemorrhagiae'' transmitted by rats, ''L. canicola'' by dogs,'' L. grippotyphosa'' by wildlife and rarely ''L. hardjo'' by cattle. Transmission is via urine of infected animals, persistence in the environment relies on soil moisture and water ways. Venereal transmission from carrier boars and sows is also responsible for infection and maintenance of the disease

Paired serum samples showing a positive rise in antibody titre can be used in some cases for confirmation of infection. The organism can be isolated by culture in a special medium, of it can be viewed under dark field microscopy.
