Which diseases are known to be zoonotic?

Brucellosis is notably considered a zoonotic disease because it can be transmitted from animals, particularly livestock such as cattle, goats, and sheep, to humans. This transmission can occur through direct contact with infected animals or their bodily fluids, as well as through the consumption of unpasteurized dairy products. The risk associated with brucellosis emphasizes the importance of proper handling of animals and adherence to food safety practices in both veterinary and agricultural settings.

While other diseases listed can also pose risks, they differ in their zoonotic potential. Coccidiosis primarily affects the intestinal tract of a variety of animals and is caused by protozoan parasites, but it is not typically transmitted to humans. Giardiasis, caused by the Giardia parasite, can indeed be zoonotic; however, it mainly spreads through contaminated water rather than direct animal-to-human transmission. Salmonellosis is another disease that does have zoonotic transmission routes, especially from reptiles, poultry, or contaminated food. However, the distinct characteristics and transmission methods of brucellosis firmly classify it among the significant zoonotic diseases that require attention in veterinary practices and public health.
