This disease, caused by Listeria monocytogenes bacteria, affects domestic animals and can be transmitted through contaminated feed or water. It is prevalent in winter and spring, with symptoms including facial nerve paralysis, encephalitis, and digestive issues. Proper management practices are crucial to minimize the risk of infection.
