Identification of Mortierella wolfii, a causative agent of mycotic abortion in cattle.

Of several media tested for their ability to induce asexual reproduction in confirmed or suspected isolates of Mortierella wolfii obtained from cattle in various geographical locations, only silage extract agar worked consistently and rapidly. Its use should provide a simple reliable culturing procedure to assist with identification of clinical isolates of this fungus. Temperature growth response curves and electrophoretic patterns of soluble protein extracts of these isolates with characteristic morphological features of M. wolfii indicate substantial variation amongst them.
