Which is NOT a differential for an infectious disease causing oral lesions in cattle?

Traumatic Stomatitis is not considered a differential for an infectious disease causing oral lesions in cattle because it is primarily a non-infectious condition resulting from trauma or injury to the oral cavity. This could occur due to rough feed, foreign bodies, or other mechanical damage rather than being caused by a pathogen.

In contrast, the other options listed—Bovine Viral Diarrhea Virus, Foot and Mouth Disease Virus, and Malignant Catarrhal Fever Virus—are all viral infections known to cause oral lesions in affected cattle. Each of these infectious diseases can lead to specific clinical signs, including lesions in the mouth, which are characteristic of their pathogenesis. Therefore, Traumatic Stomatitis stands out as a non-infectious cause, differentiating it from the others that are associated with infectious processes.
