[The morphologic characteristics of microscopic fungi of genus coccidioides].

The morphologic characteristics of microscopic fungi of genus Coccidioides under cultivation in nutrient mediums are studied. It is demonstrated that filamentous form of agents of coccidioidomycosis is characterized by significant polymorphism of macro- and micromorphologic signs on different stages of development ofagar culture. But C. immitis and C. posadasii have no species' differences. The dynamics of development of coccidioidomycosis strains in microcultures is analyzed as well as the intensity of sporification. The forms and sizes of arthroconidiae are also established.
