THE USE OF COCCIDIOIDIN

Abstract
The prepn. and properties of coccidioidin derived from various strains of Coccidioides grown in asparagin medium are described. The coccidioidin sensitivity is the usual "bacterial" type and is not transferrable passively. A low level of coccidioidin sensitivity is generally associated with the dissemination of coccidioidal infection and, in several instances, increasing sensitivity has been noted when the infection improves. The technical aspects of coccidioidin testing are considered.
