Description
Description
Brucellosis: The Silent Threat to Livestock and Human Health offers an in-depth look into the challenges posed by brucellosis, including its prevention, control, diagnosis, and treatment in animals and humans. This zoonotic disease is a significant concern not only for animal health but also public health, creating an economic burden worldwide. As the first comprehensive reference on brucellosis in decades, this book provides valuable insights into combating and managing the disease in herds and communities. The book emphasizes the importance of the One Health approach, presenting a global perspective on brucellosis.
In addition, it discusses the contagious nature of the disease and its impact on livestock and humans, particularly those working in animal husbandry. The book serves as a foundation for new research, highlighting the need for further studies due to the lack of a cure for animals and the difficulties in treating humans.
