Pulmonary botryomycosis in a Scottish highland steer.

Pertinent necropsy findings in a 5 1/2-year-old Scottish Highland steer with chronic intractable pneumonia and cough were limited to the pulmonary system. The accessory lobe of the lung was collapsed, scarred, and multifocally adhered to parietal pleura. A polypoid mass almost completely obstructed the lobar bronchus and protruded into the trachea; mucopurulent exudate distended more distal bronchi. Botryomycosis was diagnosed when histologic examination revealed pyogranulomatous pneumonia with eosinophilic granules and "club" formation surrounding colonies of gram-positive cocci. Staphylococcus aureus was cultured from the lung. Botryomycosis is an unusual response to infection with common bacteria and is characterized by pyogranulomatous inflammation with formation of eosinophilic granules surrounding colonies of gram-positive cocci or gram-negative bacilli. Among domestic species, staphylococcal botryomycosis is most common as a wound infection in horses or as mastitis in cows and sows. Pulmonary botryomycosis is rare in horses, humans, and guinea pigs and apparently has not been reported in cattle.

Acute pulmonary Sarcocystis falcatula-like infection in three Victoria crowned pigeons (Goura victoria) housed indoors.

Three free-roaming Victoria crowned pigeons (Goura victoria) housed in a completely enclosed tropical exhibit were found dead without antemortem signs of illness. The birds died within 9 days of each other. Gross necropsy revealed moderate pulmonary edema in all three birds. Histopathologic examination revealed pulmonary edema and pulmonary protozoal merozoites compatible with Sarcocystis spp., Toxoplasma gondii, or Neospora spp. infection. Immunohistochemical staining for T. gondii and Neospora spp. were negative. Immunohistochemical staining identified a Sarcocystis falcatula-like parasite in all three birds. It is suspected that new exhibit soil contaminated with feces from the Virginia opossum (Didelphis virginiana) was the source of the infective sporocysts.

Cuterebra myiasis in a group of red kangaroos (Megaleia rufa), a Bennett's wallaby (Macropus rufogriseus fruticus), and a Gunther's dik dik (Maloqua guentheri smithi).

A group of four red kangaroos (Megaleia rufa), a Bennett's wallaby (Macropus rufogriseus fruticus), and a Gunther's dik dik (Maloqua guentheri smithi) were presented over a 2-mo period with draining lesions over the thorax or on the lateral aspect of a hind leg. Only one animal exhibited more than one lesion. Physical examinations revealed infections with fly larvae. The parasites were manually removed and identified as Cuterebra spp. All of the affected animals survived, with no apparent side effects.

Ventricular septal defect in a blue duiker (Cephalophus monticola).

A 9-mo-old female blue duiker (Cephalophus monticola) weighing 3.9 kg was diagnosed with a cardiac murmur during quarantine examination. Evaluation of the heart by auscultation, electrocardiography, two-dimensional echocardiography, and Doppler color-flow echocardiography revealed a restrictive outlet ventricular septal defect with left atrial and left ventricular dilation. Trivial mitral, tricuspid, and aortic regurgitation was also noted. Though the duiker was clinically asymptomatic at the time of cardiac evaluation, it was found dead 1 wk later. The cause of death was not determined.

Congenital ocular anomalies and ventricular septal defect in a dromedary camel (Camelus dromedarius).

A 5-wk-old female dromedary camel (Camelus dromedarius) was clinically diagnosed with bilateral corneal dermoids, incomplete congenital cataracts, a left persistent hyaloid artery (PHA), and a ventricular septal defect (VSD). The corneal dermoids were removed by lamellar keratectomy, and vision improved in the left eye. Thirteen months after dermoid surgery, the calf was presented for enlargement of the right eye. Glaucoma was confirmed in the right eye, and corneal fibrosis and cataract were noted in the left eye. Persistence of the VSD was confirmed by cardiac ultrasonography. The calf was euthanized, and necropsy findings confirmed VSD. Histopathologic examination revealed bilateral corneal thinning and fibrosis, cataracts with retrolental fibroplasia, and retinal dysplasia. Additional changes in the right globe were anterior segment dysgenesis, ruptured lens capsule, chronic phacoclastic uveitis, and retinal separation. The PHA was confirmed in the left eye.

Pulmonary silicosis in three North American river otters (Lutra canadensis).

Three adult female North American river otters (Lutra canadensis) demonstrated severe anesthetic complications shortly after being immobilized for dental procedures. Two of the animals died shortly after anesthesia, and the third otter died 2 mo after immobilization. All three animals were diagnosed with pulmonary silicosis on the basis of histopathology, polarized light microscopy, and mass spectrometry. One animal also had primary pulmonary bronchoalveolar carcinoma. Significant concurrent disease was not found in other organs. Analysis of the lung tissue by laser microbe mass spectrometry confirmed the presence of an aluminum silicate in the lung tissue associated with insulation material used in nest box construction.

A World Wide Web accessible multi-species ECG database.

We have developed a system for remotely accessible secure electronic storage of electrocardiographic (ECG) and other associated data. It allows entry of data from any authorized remote user and is specifically built to accommodate the ECGs of multiple species. The present system is implemented on a Sun Sparc Solaris 2.5 platform using Oracle 7.3.2, and the Oracle 7.3.2 Web server. It may be easily ported to any other UNIX or Windows NT platform. No client is needed other than an Internet Protocol connected computer using a web browser such as Netscape Navigator or Microsoft Internet Explorer.
