Adult volunteers were skin tested with 1.27 ug spherule-derived coccidioidin. The skin test antigen was evaluated in three different populations of adult volunteers to determine the safety and efficacy of the product in the assessment of delayed-type hypersensitivity to Coccidioides immitis. Induration greater than or equal to 5 mm after 48 hours was considered positive for exposure to C. immitis.

1: Active Comparator
Volunteers with a history of pulmonary coccidioidomycosis verified by serology and/or histology or mycology.
|
Biological: Spherule-derived coccidioidin
1.27 ug of sterile, injectable product (spherule-derived coccidioidin). Product was administered once by intradermal injection along with positive and negative control agents and results read after 48 hours.
|
2: Active Comparator
Volunteers without a history of pulmonary coccidioidomycosis confirmed by serology (naive).
|
Biological: Spherule-derived coccidioidin
1.27 ug of sterile, injectable product (spherule-derived coccidioidin). Product was administered once by intradermal injection along with positive and negative control agents and results read after 48 hours.
|
3: Active Comparator
Volunteers with a history of pulmonary histoplasmosis but no history of coccidioidomycosis confirmed by serology.
|
Biological: Spherule-derived coccidioidin
1.27 ug of sterile, injectable product (spherule-derived coccidioidin). Product was administered once by intradermal injection along with positive and negative control agents and results read after 48 hours.
