Leptospirosis is an infection in animals caused by Leptospira interrogans bacteria, leading to intoxication, damage to internal organs, and, ultimately, death. Leptospires can remain active in the environment for a long time and accumulate in stagnant water or moist soil. Rodents and infected animals often serve as carriers. Infection can have catastrophic consequences for farms. Calves are among the most severely affected by leptospirosis. The disease is also no less dangerous for humans.
A frequent cause of the disease is failure to follow proper grazing practices and hygiene in animal housing. Infection usually occurs in warm weather on marshy pastures or through bedding and feed previously contaminated with leptospirosis, for example by rodent feces or the urine of another animal. Leptospires enter through any wounds in the skin or mucous membranes, quickly enter the bloodstream, and spread throughout the body. This leads to the destruction of red blood cells in the blood, which is reflected in characteristic symptoms as early as 2-5 days after infection.
Diagnosis is based on the clinical picture and is supported by bacteriological, microscopic, histological, serological, and pathological examinations.
