Abstract
In August, 1986, a 10 days old Holstein calf lied, demonstrating neck stiffness and out-stretched limbs. It presented such symptoms as extreme sensitivity to noise. At autopsy, thepia mater and the cervical meninges were profusely cloudy and thickened. Fibrin clot was found in the cervical subdural space. Histologically, the disease was diagnosed as a purulent meningoencephalomyelitis. Enterobacer cloacae was isolated from the brain.
