title: Experimental hypersensitivity pneumonitis: reduced severity of clinical response following repeated injections of Micropolyspora faeni antigen.
abstract: Subcutaneous injection of soluble M. faeni antigen administered during a series of aerosol provocations to previously sensitized calves was found to diminish severity of clinical response. The mechanism by which response was reduced was not apparent.
