Tracheal resection and anastomosis for an intratracheal chondroma in a ball python.

A 9-year-old female ball python was evaluated for lethargy and respiratory compromise. Radiographic and endoscopic examination revealed a 1-cm intratracheal mass occluding the tracheal lumen. A partial tracheal resection and anastomosis was performed to remove the mass. On histologic examination, the mass was determined to be an intratracheal chondroma. Eosinophilic cytoplasmic inclusions observed within the tissue were calcium deposits. Electron microscopy was used to differentiate these from viral inclusion bodies often associated with neoplasms in reptiles. Endoscopic evaluation of the trachea 5 weeks after surgery revealed complete healing and minimal stenosis at the surgery site. Indications of tumor regrowth were not evident. Clinical signs of recurrence of respiratory compromise had not been observed 9 months after surgery.

Evaluation of selected plants for their toxic effects in canaries.

Leaves or fruit from 14 plants considered to be toxic to pet birds were administered by gavage to 15 pairs of canaries (Serinus canaria). Each bird was given 0.12 to 0.70 g of plant material. One pair served as a control and was given distilled water. The plant materials were flash-frozen in liquid nitrogen, pulverized, and resuspended in deionized water for administration. Of the plants tested, 5 (oleander, lupine, foxglove, yew leaves, and dieffenbachia) were considered highly toxic and were associated with acute death of birds. The remaining plant samples caused no, or only transient, clinical illness.

Evaluation of selected plants for acute toxicosis in budgerigars.

Pairs of budgerigars were given samples, by gavage, of plants considered potentially toxic to pet birds. Samples were prepared by flash-freezing and powdering fresh plant material in liquid nitrogen and resuspending the material in deionized water for administration. Of the 19 plants tested, only 6 induced clinical signs of illness; these plants included yew, oleander, clematis, avocado, black locust, and Virginia creeper (Taxus media, Nerium oleander, Clematis sp, Persea americana, Robinia pseudoacacia, Parthenocissus quinquefolio).

Polyostotic hyperostosis associated with oviductal tumor in a cockatiel.

A 10-year-old female cockatiel in a thin and depressed condition and with a 1 X 2-cm soft abdominal swelling was hospitalized. Radiography revealed a well-circumscribed mass containing punctate areas of mineralization, displacing the gizzard cranially in the caudodorsal portion of the abdomen. There was bilateral, symmetric, generalized, increased medullary opacity of the radius, ulna, carpometacarpus, femur, tibiotarsus, and tarsometatarsus. These findings were compatible with polyostotic hyperostosis secondary to an estrogen-secreting tumor. Euthanasia and necropsy were requested. A small area of neoplastic cells in the oviduct was identified histologically, but most of the tissue mass consisted of necrotic cellular debris. There was no metastasis. Sagittal secretions of decalcified radiopaque bones revealed up to 60% filling of medullary cavities with bone spicules. Although clinical and radiographic findings were compatible with an estrogen-secreting tumor, osteopetrosis, metastatic neoplasia, hypertrophic osteopathy, and metabolic bone disease were included in the initial differential diagnosis. The absence of metastasis and the confinement of the tumor within the oviduct would have made surgical removal a possible approach to treatment.

Mast cell tumors in three ferrets.

Pruritic open skin lesions (5 mm diameter) on the thorax, neck, or head of 3 ferrets were diagnosed as mast cell tumors. Diagnosis of the tumors was based on histologic examination of biopsy specimens. Histologic diagnosis was necessary because the lesions had been treated as mycotic or bacterial ulcers and did not respond to conventional treatment. Excised mast cell tumors did not recur, and malignant behavior of the tumors was not observed.

Avocado (Persea americana) intoxication in caged birds.

Avocados of 2 varieties were mashed and administered via feeding cannula to 8 canaries and 8 budgerigars. Two control budgerigars were given water via feeding cannula. Six budgerigars and 1 canary died within 24 to 47 hours after the first administration of avocado. Deaths were associated with administration of both varieties of avocado. Higher dose was associated with greater mortality. The 2 budgerigars given water were normal throughout the observation period. Results indicated that avocados are highly toxic to budgerigars and less toxic to canaries. Postmortem findings observed in some birds included subcutaneous edema in the pectoral area and hydropericardium.

Experimental intraamnionic exposure of bovine fetuses with subgroup 2, type 7 Adenovirus.

Three third trimester fetuses were exposed to a subgroup 2, type 7 adenovirus (adeno 7) by intraamnionic infection. The virus caused preterm delivery of two clinically ill calves and one stillbirth. The two premature calves died 12 and 72 hours after birth. An elevated serum neutralizing antibody titer (1:256) to adenovirus 7 was found in one principal calf at birth. Adenovirus 7 was recovered from several tissues of the live calves and the spleen of the stillborn calf. Fetuses exposed by intraamniotnic injection with virus carrier only, were born healthy after normal gestational periods and no viruses were isolated from the tissues. Clinically ill calves were weak, severely depressed and unable to stand and nurse. Gross postmortem lesions were nonspecific and consisted of petechial and ecchymotic hemorrhages and edema of the gastrointestinal tract. Histopathological lesions included vasculitis, necrosis of the mucosa of the forestomach, mild gastroenteritis and acute, nonsuppurative focal necrosis of the liver, kidney and adrenal gland. Intranuclear inclusion bodies were seen in pericytes, macrophages, hepatocytes, epithelial cells of adrenal cortical sinusoids of the zona glomerulosa and zona fasciculata and renal tubular epithelium.

Selected oxygen transport parameters in captive elk.

Five captive elk (cervus canadensis) were immobilized with a mixture of etorphine HC1-acepromazine maleate, and measurements were taken of selected oxygen transport paraments. Heart mass/body mass, hematocrit, hemoglobin, blood volume, mean corpuscular volume and airway resistance were measured and the values compared to other ungulates. It was concluded that the O2 transport system of elk is not as well developed as that in pronghorn but is superior to that found in the goat or ox.
