title: Systemic infection with Mortierella wolfii following abortion in a cow.
abstract: Severe meningoencephalitis and endometritis associated with necrotizing vasculitis, thrombosis, and infarction were found at necropsy of a 4-year-old Aberdeen Angus cow with a history of abortion and neurological signs. Focal pyogranulomatous pneumonia and nephritis were also present. Fungal hyphae typical of zygomycetes were abundant within lesions, and Mortierella wolfii was cultured from multiple tissues. This is believed to be the first report of systemic mortierellosis following abortion in North America, and the second reported instance of encephalitis caused by M. wolfii in a cow.
