An Analysis of Skin Test Responses to Spherulin-Based Coccidioidin (Spherusol®) Among a Group of Subjects with Various Forms of Active Coccidioidomycosis

Background A reformulated skin test for coccidioidomycosis, Spherusol®, was recently approved for use in the USA. We hypothesized that it could be useful in predicting severity of illness and outcome in various types of coccidioidomycosis.
