Step-by-step explanation:
Cattle are commonly vaccinated against Leptospirosis, a zoonotic disease that can be spread by the urine of deer and rats, among other animals. Leptospirosis is caused by bacteria of the genus Leptospira. Infected animals can contaminate water and soil with the bacteria, creating a risk of transmission to other animals, including humans. Vaccination of cattle is an important preventative measure for this disease, which can lead to serious health issues such as liver and kidney damage or even death.
