''Leptospira'' is a motile, helical bacteria found in aquatic environments. It causes '''Leptospirosis''' in all animals, which can range from mild urogenital tract infections to systemic diseases. The organisms persist in the kidney tubules or genital tracts of carrier animals and are shed in urine. Transmission occurs via direct contact. Maintenance hosts may transmit the infection to incidental hosts, which are less susceptible to infection, but develop serious disease. ''Leptospira'' may cause severe systemic disease, resulting in [[Septicaemia and Enteritis, Bacterial|enteritis]]. | ''Leptospira'' is a motile, helical bacteria found in aquatic environments.
