The double immunodiffusion technique was applied to avian encephalomyelitis virus (AEV). Agar gel medium containing such a high concentration of NaCl as 15% was more preferable for highly diluted quantities of reactants than any other NaCl-containing medium. A single precipitin line appeared on the 1st to 7th days of diffusion at room temperature. The specificity of reaction between AEV antigen and homologous immune chicken serum has been demonstrated by no cross reaction between heterologous viruses and specific absorption by homologous virus. The antigen was produced in the brain, viscera, eyeball, whole body and yolk sac of chick embryos inoculated via yolk sac, as well as in the thigh muscles of chicks subcutaneously inoculated at 2 days of age. Antigenicity was detectable in 50% emulsion of these organs with a virus titer more than 10(5.0) per 0.1 g of tissue weight.

Blastomycosis was diagnosed in six nondomestic felids from eastern Tennessee, including two Asian lions (Panthera leo persicus), one African lion (Panthera leo), one Siberian tiger (Panthera tigris), one cheetah (Acinonyx jubatus), and one snow leopard (Panthera uncia). Clinical signs included lethargy, anorexia, weight loss, dyspnea, sneezing. ataxia, and paresis. Variable nonspecific changes included leukocytosis, monocytosis, moderate left shift of neutrophils, moderate hypercalcemia, hyperproteinemia, and hyperglobulinemia. Thoracic radiographs revealed interstitial and alveolar changes, consolidation or collapse of a lung lobe, bullae formation, and a pulmonary mass. Agar gel immunodiffusion (AGID) serology for Blastomyces dermatitidis was performed in five felids and was positive in three. The tiger had cerebral blastomycosis and was positive for AGID serologic tests of both cerebrospinal fluid and serum. One percutaneous lung aspirate in the snow leopard and one bronchial aspirate in an Asian lion demonstrated B. dermatitidis organisms. whereas tracheal wash samples and a nasal discharge were nondiagnostic in others. Treatment with itraconazole was attempted in four cats. The tiger improved before euthanasia, whereas the others did not survive beyond initial treatments. In four felids, B. dermatitidis was found in the lungs and tracheobronchial lymph nodes associated with a florid pyogranulomatous reaction; the tiger had a pyogranulomatous encephalomyelitis, and the cheetah had a single pulmonary granuloma. Thoracic radiography, cytologic examination of lung lesion aspirates, and B. dermatitidis AGID serology should be performed on clinically ill zoo felids in endemic areas to rule out blastomycosis.
