Life cycle of Coccidioides. Coccidioides spp. alternate between saprobic (mycelia) (left) and parasitic (spherules) (right). The saprobic cycle is found in the environment and produces infectious arthroconidia. They may become airborne and be inhaled by the host or may return to the environment to continue the saprobic life cycle. (Adapted from reference 11, published under a Creative Commons license.)
