NR-4548 was derived from Coccidioides posadasii (C. posadasii) strain C735 by selective disruption of the chitin synthase 5 (chs5) gene.

The strain is incapable of forming arthroconidia or spherules, or of reproduction in the parasitic phase, thereby rendering it avirulent. The strain was tested in a murine model of coccidioidomycosis and confirmed to be avirulent.

Each vial of NR-4548 contains approximately 1 mL of fungal culture containing 10% DMSO.
