An adult female hyacinth macaw (Anodorhynchus hyacinthinus) was presented for sudden onset of severe weakness in the legs. Neurologic examination revealed bilateral paresis of the pelvic limbs and decreased proprioception. Results of radiographs and computed tomography (CT) revealed variably sized...

The importance of cellular infiltrates in tissues has been investigated as a diagnostic tool, mechanism of pathogenesis, and prognostic indicator in certain human diseases. Eosinophils, in particular, have a distinct role in the development of cutaneous lesions in human autoimmune diseases....

Skin biopsies are a viable diagnostic tool in avian dermatology, however, the thinness of avian skin makes it difficult to prevent rolling and contraction of skin biopsy specimens during collection and fixation. The difficulty orienting such rolled samples during processing ultimately interferes...

Acute toxoplasmosis was diagnosed in 3 gray squirrels (Sciurus carolensis) from Louisiana and Pennsylvania. The predominant lesion was multifocal necrosis in several organs, especially of the lymph nodes. Numerous Toxoplasma gondii tachyzoites were seen in lesions, and the diagnosis was confirmed...

The objectives of this study were to characterize the role of intermittent vs. continual flea exposure in the development of flea allergy dermatitis (FAD) in cats, assess the accuracy of intradermal skin testing (IDST) and in vitro testing, and document the incidence and histopathological features...

An oomycotic pathogen in the genus Lagenidium was isolated from tissues obtained from 6 dogs with progressive cutaneous disease. Initial clinical findings in 5 dogs included multifocal cutaneous lesions, subcutaneous lesions, or both associated with regional lymphadenopathy; the 6th dog initially...

The effect of hyperbaric oxygen (HBO) on skin grafts was investigated in 40 Sprague-Dawley rats. The cellular effects of oxidative stress (measured by total glutathione, glutathione peroxidase activity, and presence of thiobarbituric acid reactive substances) were apparent in all rats given skin...

Juvenile rhabdomyosarcomas were diagnosed in 2 young dogs based on the results of histopathology, phosphotungstic acid-haematoxylin stain, immunohistochemistry, and the age of the dogs. One dog, an 11-month-old Rottweiler, had tumour masses in the maxillary gingiva and the urinary bladder....

Free, autogenous, full thickness skin grafts were applied to 10 dogs; 5 dogs were given an iron chelator, deferoxamine 10% hydroxyethyl pentafraction starch (DEF-HES; 50 mg/kg of body weight,i.v.), and 5 dogs were given an equal volume of 10% hydroxyethyl pentafraction starch (HES) in 0.9% saline...
