and to histoplasmin.
13) later used T27K, a coccidioidal antigen preparation, we elected to use coccidioidin
filtrate, which has historically been shown to be a good coccidioidal preparation for DTH testing and to be an even better preparation for determining cellular immunity in vitro (14).
2) Routine skin testing with coccidioidin
(spherulin) in coccidioidomycosisendemic areas is not predictive of disease and should not be performed (Ell).
immitis by positive coccidioidin
or spherulin skin tests.
The mycosis is presently considered to be endemic to Northeast Brazil, as evidenced by human autochthonous cases (6-8), positive coccidioidin
skin-test results (7), and isolation of the fungus from soil (7,9).
