North American blastomycosis in California.  Diagnosis of a case and a survey with 28 California observed cases.
North American blastomycosis is not seen often in California. An exhaustive survey uncovered records of only 28 cases. It is believed that this disease does not occur naturally in California and that a careful study of the history will reveal that a residence or visit to a known endemic area can be found.A chart summarizing the results of complement fixation and skin tests for coccidioidomycosis, North American blastomycosis, and histoplasmosis in the 28 cases is included. Use of all three antigens is recommended in cases where there is a difficult diagnostic pulmonary problem, even though there is occasional occurrence of cross-reactions between the three antigens. Finally, an appeal is made to be aware of other mycotic diseases non-edemic to this state.
