A 2-month-old male domestic shorthair cat was referred to a private veterinary clinic with a history of dyspnea and inappetence. At the clinical examination, the cat was in poor body condition, with hyperthermia and abdominal distension. No major abnormalities were observed in the thoracic radiographs or abdominal ultrasound. A complete blood count revealed leukocytosis with neutrophilia. Although no clinical diagnosis was made, the cat received support therapy, but went into cardiac arrest and died. The cat was submitted for necropsy and the main gross finding was two white nodules on the ventral surface of the thoracic vertebrae (from T1 to T4). At the cut surface, the nodules were friable and filled with yellow exudate. The epidural space of the thoracic region was filled with yellowish viscous material. Histologically, the vertebrae were partially replaced by abscess formation characterized by a necrotic center with degenerate neutrophils, surrounded by fibrous connective tissue. The epidural space was filled with degenerate neutrophils, necrotic debris, fibrin, and intralesional colonies of gram-negative short rod-shaped to coccobacillary bacteria. Bacteriologic culture yielded Pasteurella multocida. This paper describes the gross, histological, and bacteriological features of a rare case of spinal epidural empyema caused by Pasteurella multocida in a cat.
Clinical History: A one-year-old female Texel sheep had anorexia and jaundice. After one day, the clinical condition progressed to lethargy, lateral recumbency, and death within hours. The sheep was part of a flock of 20 housed indoors and received an increasing amount of feed (specific for sheep) for the last two months. Gross Findings: The sheep was in excellent body condition. The carcass was discolored by marked icterus. In the subcutaneous tissue, there was multifocal petechiae and ecchymosis. The kidneys had a deep red-brown discoloration. The urinary bladder was distended and filled with dark red to black urine. The liver was slightly soft and swollen, with a deep orange hue. The gallbladder was distended and filled with dark grumous bile.
Clinical History: A 2-year-old, female Poodle dog presented to the Emergency Service at the Veterinary Teaching Hospital (VTH), Louisiana State University School of Veterinary Medicine with a history of lethargy and anorexia. At clinical examination the dog was anemic and febrile. The dog was bilaterally blind. The right eye was buphthalmic and the intraocular pressure was elevated (42 mm Hg). During an ophthalmological consult, bilateral severe panuveitis and optic neuritis with secondary glaucoma in the right eye was diagnosed and treatment was instituted. Despite treatment, the intraocular pressure kept increasing (up to 72 mm Hg overnight), and the clinicians decided to enucleate the right eye due to poor prognosis. After one month, and no response to treatment, the left eye was also enucleated. Gross Findings: Right and left eyes: The vitreous chamber was filled with a yellow, gelatinous exudate while the anterior chamber was filled with a translucent, gelatinous fluid. The retina appeared detached and embedded within the exudate present in the vitreous chamber.
