From: What have we learned from brucellosis in the mouse model?
DTH in B. abortus S19 infected mice after footpad injection of Brucella protein extracts. Note the biphasic response between the acute and chronic steady phases. The blue line in the graphic is compatible with type IV hypersensitivity, while the red line is compatible with a mix reaction of type IV and type III hypersensitivity (adapted from [153], with permission).
