My dermatitis was treated by a dermatologist.

I am interested in dermatology.

This antitoxin is used to counteract that toxin.

My grandfather is receiving treatment for skin cancer.

He is going to the dermatologist for the treatment of dermatosis.

This bacterium produces a powerful endotoxin.

Exotoxin is a harmful substance produced by bacteria.

This drug does not contain endotoxins.
