WebIn infected tissues and in specialized liquid growth media, Coccidioides produces thick-walled structures called spherules, which reproduce by endosporulation, a process by which the interior of the spherule is divided into as many as several hundred individual cells (endospores) ( Figure 3 ). WebThe spherules cannot normally be induced in culture, but require inhalation into an animal. These spherules bear a superficial resemblance to a chicken protozoan parasite Coccidia; Coccidioides literally means "like Coccidia" and immitis means "not mild." Incidentally, the other type of conidiation, far more common, is blastic conidiation.
