LEPTOSPIROSIS AETIOLOGY


Dogs can be infected with several serovars of Leptospira interrogans, but those most often found are icterohaemorrhagiae, canicola and grippotyphosa. The sources of infection in dogs are usually environmental - particularly slow moving water and contact with rodents, but also bite wounds, infected meat and even placental transfer.
A combination of hygiene and vaccination means that canine leptospirosis is commonly reported in many areas. Affected dogs are usually unvaccinated with a history of swimming in stagnant or slow-moving water.
