Leptospirosis in Pigs

Leptospirosis is a bacterial infection that colonises the kidneys and genital tract of the host.

The disease can be spread to humans and other animals when leptospires are shed in the urine and from the reproductive tract into the surrounding environment.

L. tarassovi and L.pomona are usually the most common types found in pigs.

Clinical signs of leptospirosis in pigs can include abortion, weak or stillborn piglets, which can all affect the productivity and profitability of the herd.

Symptoms in humans range from profound fatigue and headaches to muscular aches and vomiting. Usually, infected people return to work within 3 to 4 weeks, however continuing relapses can occur. The disease is a significant occupational health and safety issue for pigs, producers and the most important method of prevention is vaccination of the herd.
