ABSTRACT
A 10-year-old mixed-breed dog was examined because of lameness and mutilation of the left hind limb. Neurologic examination revealed ataxia, conscious proprioceptive deficit, muscle atrophy, lack of withdrawal reflex, and hyperreflexia of the patella of the left hind limb. Epidurography revealed right-sided deviation of the dye column at the sixth to seventh lumbar vertebrae. Laminectomy with cytoreduction was performed, and histologic examination revealed ganglioneuroma. Twelve months after surgery, clinical signs recurred and surgery was repeated. The dog's clinical signs were again palliated. The specific type of ganglioneuroma identified in this dog is amenable to surgical resection, unlike many types of spinal cord neoplasia.

In 1990, Salmonella enteritidis phage type 4 was recovered from two young (less than 20-week-old) lilac-crowned Amazon parrots (Amazona finschi Schlater), one in Tennessee and one in Kansas. The parrot from Tennessee was treated for a plugged naris and anorexia before the S. enteritidis infection was discovered. The parrot from Kansas exhibited signs of septicemia and died within 24 hours of examination. An apparently healthy green-cheeked conure (Pyrrhura molinae) on the same premises as the parrot from Tennessee was positive for S. enteritidis phage type 4 on a cloacal swab. These are the first reported cases of avian infection with S. enteritidis phage type 4 in the United States. Because several infectious agents were present simultaneously in the Amazon parrots, it was difficult to determine the precise role of S. enteritidis phage type 4 in the clinical presentations.

Various different combinations of histochemical stains at differing pH levels on single sections of bovine skeletal muscle were evaluated. The staining sequence that was the most consistent and reliable of those studied included an initial NADH-TR (reduced nicotinamide adenine dinucleotide-tetrazolium reductase) followed by an acid ATPase stain at pH 4.15. This staining combination resulted in easily discernable type I, II A, and II myofibers. Thus, a marked saving of expended time, labor and materials was realized.
