Abstract
Partially purified leukocidin from Fusobacterium necrophorum damaged bovine peripheral leukocytes as demonstrated by trypan blue staining. Granulocytes were most and T-lymphocytes least sensitive to the leukocidin. Heating for 30 min at 60 degrees C completely inactivated the leukocidin. The cytotoxicity of the leukocidin could be neutralized by homologous anti-leukocidin. Scanning electron microscopy of the exposed cells revealed an apparent destruction of the cell membranes, loss of the microvilli and smoothing of the cell surfaces.
