Bovine fetal cerebral absidiomycosis.

Only 1 case of fetal cerebral mycosis was found in 4015 aborted bovine fetuses. Absidia corymbifera was associated with vasculitis, thrombosis, abscessation and cavitation of the brain. Antibodies against A. corymbifera and other fungal antigens were not detected in fetal serum by immunodiffusion techniques. Immunoglobulin G (IgG) in excess of the normal was detected in the fetal serum by radial-immunodiffusion assay.
