'''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 whih 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.
