Question of the Day

The top differentials for vesicular disease in cattle include foot-and-mouth disease (FMD) and vesicular stomatitis.

The US has been free of FMD since 1929, therefore FMD is a reportable disease. The disease affects cloven-hoofed animals. Pigs and cattle are most severely affected.

Vesicular stomatitis is clinically indistinguishable from FMD but also can affect horses. 

Bovine papillar stomatitis causes proliferative raised lesions.

Bluetongue primarily affects sheep (typically subclinical in cattle). It causes vasculitis with clinical presentation of fever, edema, reluctance to eat/move.
