A - Contagious ecthyma
B - Tick bite hypersensitivity
C - Photosensitization
D - Dermatophytosis
E - Squamous cell carcinoma
C is the right answer!
This is an example of Photosensitization. Notice that the areas covered by
black fur are not affected. The most common cause in cattle is impaired
hepatobiliary excretion (secondary or type III photosensitization).
Dermatophytosis causes hair loss, but not the vesicles and ulceration seen
with photosensitization.
