We vaccinate to stimulate the immune system to protect animals from diseases.
In production animals, one of the most important vaccines that we use covers Clostridial diseases and Leptospirosis. Blackleg, Pulpy Kidney, Tetanus, Black Disease and Malignant Odema are some of the Clostridial diseases that vaccinating protects against.
They can be picked up from the soil and the first sign of having a problem is usually sudden deaths.
Leptospirosis is a terrible bacterial disease spread to our animals from rodents and water contaminated with urine. Infected animals may appear a bit 'off colour' while others can seem clinically normal.
What we don't see is that these animals are shedding leptospira in their urine.
