What is the term for an infection caused by an insect that primarily affects a cow's eyes?

1. Pinkeye

2. Pink rash

3. Eye worm disease

4. Corneal opacity

The correct answer is: Pinkeye

Pinkeye, also known as infectious bovine keratoconjunctivitis, is the term used for an eye infection in cattle that is primarily caused by the bacteria Moraxella bovis and often involves irritation from external factors, such as flies. These insects carry the infectious agents and can cause significant inflammation and discomfort in the cow's eye, potentially leading to severe health issues if not treated properly. The other options describe different conditions or terms that are not specifically related to the typical and common eye infection associated with insects in cows. Pink rash, for instance, does not pertain to eye infections; rather, it might refer to skin conditions not specific to cattle. Eye worm disease references a parasitic condition but does not directly link to the primary infectious agent for eye problems in cows. Corneal opacity describes a symptom often seen in eye diseases but does not specifically identify a disease caused by an insect. Thus, pinkeye stands out as the widely recognized and specific term related to insect-induced eye infections in cattle.
