Leptospirosis is amongst one of the most common cause of infectious abortion in cattle. It is caused by bacteria that affect many kinds of animals as well as humans. The bacteria are spread by the urine of sick and carrier animals contaminating feed and water. The bacteria enter the cow through breaks in the skin on feet and legs when walking in contaminated water, or through the nose, mouth, or eyes by contact with contaminated feed, water or urine. Lepto bacteria affect unborn calves. If a cow gets Lepto during the last half of gestation she will likely abort 1 to 3 weeks after recovering from the acute stage of the disease – even if the cow did not look sick she may abort. Abortions caused through Lepto often cause infection of the uterus and retained placenta, however cows usually recover and breed again. Not all infected cows abort, sometimes a cow gives birth to a live but weak calf that dies within a few days. There is a vaccine against 5 of the most common types of Lepto that cause abortion in cows and gives immunity for approximately 6 months. For good protection cows should be vaccinated twice a year, since Lepto can cause abortion at any stage of pregnancy.
