Effect of immunosuppressants on dogs exposed two and one-half years previously to Blastomyces dermatitidis.

Observation of 33 dogs exposed to Blastomyces dermatitidis over a 2 1/2 year period is reported. During the first 1 1/2 years six dogs died and 23 (77%) developed skin lesions. Clinical evidence of disease in all the animals then subsided and remained so through another year of observation.

Distribution of Blastomyces dermatitidis in dogs with skin test and serologic results following airborne infection.

Reported is a short term (16 week) experiment to determine the distribution of B. dermatitidis in dogs when infected by the natural inhalation route by receiving about 250,000 viable particles during a 24h. exposure.
