What is the name of the disease carried by insects that affects the eyes of cattle?

1. Pinkeye

2. Foot and mouth disease

3. Bovine respiratory disease

4. Brucellosis

The correct answer is: Pinkeye

The disease known as pinkeye, or infectious bovine keratoconjunctivitis, is a significant concern in cattle management. It is primarily caused by the bacterium Moraxella bovis and is often exacerbated by environmental factors and insect activity, particularly from flies. These insects can carry the bacteria from one animal to another, facilitating its spread in herds. Pinkeye manifests through symptoms such as excessive tearing, squinting, and inflammation of the eye, which can lead to serious complications if not treated promptly. It is vital for ranchers and cattle producers to recognize and manage this disease effectively, as it can impact the productivity and overall health of the cattle. In contrast, the other diseases mentioned do not specifically target the eyes of cattle. Foot and mouth disease is a viral infection causing sores in the mouth and on the feet, while bovine respiratory disease primarily affects the lungs. Brucellosis is a bacterial infection that can lead to reproductive issues but does not affect the eyes. Understanding these distinctions helps in recognizing the specific implications of different livestock diseases.
