AbstractThis chapter provides in‐depth coverage of leptospirosis including relevance, potential public health significance, epidemiology, pathogenesis, clinical signs, lesions, diagnosis, immunity, and prevention and control. Leptospirosis is a cause of reproductive loss in breeding herds and has been reported in swine from all parts of the world. However, knowledge of the incidence and economic impact of the disease is largely confined to Argentina and Brazil and to the intensive pig industries of the Northern Hemisphere, Australia, and New Zealand, where its importance has apparently declined. The epidemiology of swine leptospirosis is potentially very complicated, since swine can be infected by any of the pathogenic serovars. Abortions, stillbirths, the birth of weak piglets of reduced viability, and reduced litter size are primary signs of chronic leptospirosis, particularly Pomona infection. Control of leptospirosis is dependent on the combined use of three strategies: antibiotic therapy, vaccination, and management.
