RT Journal Article SR Electronic T1 Blastomycosis: a new endemic focus in Canada JF Canadian Medical Association Journal JO CMAJ FD Canadian Medical Association SP 728 OP 731 VO 129 IS 7 A1 J. Kane A1 J. Righter A1 S. Krajden A1 R. S. Lester YR 1983 UL http://www.cmaj.ca/content/129/7/728.abstract AB A survey of the 38 patients resident in Ontario from whose sputum, body fluids or tissues Blastomyces dermatitidis was cultured by our laboratory between 1970 and 1981 revealed a new endemic focus to the north and east of Lake Superior, where 20 of 27 traceable patients lived. Direct microscopy revealed B. dermatitidis in 90% of the cases. A lack of clinical awareness, however, had often resulted in a delay (average 15 weeks) in diagnosis. In two cases the disease was identified only at autopsy. About 80% of the patients survived.
