What type of dermatitis is associated with strawberry footrot?

Strawberry footrot, commonly seen in livestock such as sheep and cattle, is associated with proliferative dermatitis. This type of dermatitis is characterized by abnormal growth and multiplication of skin cells, leading to the formation of thickened, crusty lesions that are often red and inflamed. The term "strawberry" refers to the appearance of these lesions, resembling strawberries when viewed closely.

In cases of strawberry footrot, the condition is typically caused by a combination of factors, including the presence of certain bacteria and the environment in which the animals are kept—often wet and muddy ground, which contributes to skin irritation and damage. The proliferation of skin cells is a response to this irritation and infection, making proliferative dermatitis the most appropriate classification.

Other types of dermatitis mentioned do not fit the context of strawberry footrot. Allergic dermatitis is primarily caused by allergic reactions, atopic dermatitis is linked to genetic predisposition and environmental allergies, and contact dermatitis results from direct contact with irritating substances. Each of these forms of dermatitis has distinct triggers and characteristics, differentiating them from the proliferative nature observed in strawberry footrot.
