Successful Neoadjuvant Chemotherapy and Surgical Removal of a Nonmetastatic Testicular Round Cell Tumor in a Solomon Island Eclectus Parrot ().

An intracoelomic mass was palpated on an annual exam of a 24-year-old male Solomon Island eclectus parrot (). The initial diagnostic workup included a complete blood count, plasma biochemistry panel, and coelomic ultrasound. Computed tomography was highly suggestive of a testicular mass.

Grey parrot (Psittacus erithacus) beak papillae and nerves identified using novel 2-D and 3-D imaging modalities.

Objective: The avian beak is a complex organ containing bone, neurovascular tissue, and keratinized covering (rhamphotheca). Nerve-rich papillae extend through bone into rhamphotheca providing sensory input from the beak tip. Beak trimming is a common procedure in avian species and is used for corrective, cosmetic, and behavioral modification purposes.

Development and validation of 2 probe-hybridization quantitative PCR assays for rapid detection of a pathogenic species in captive psittacines.

Avian coxiellosis is an emerging cause of morbidity and mortality among captive psittacines, and the utility of a rapid detection test using easily obtained samples is paramount in a clinical setting. New sequences were obtained from 3 genes: , and . We developed probe-hybridization quantitative PCR (qPCR) assays using and genes.

Surgical Management of an Intrathoracic Branchial Cyst in a Yellow-crested Cockatoo ().

A 40-year-old, female lesser crested cockatoo () was presented with a complaint of hyporexia and sudden onset of sneezing and wheezing. Physical examination revealed mild stertorous inhalation, and the apex of the heart was palpable caudoventral to the distal tip of the sternum. Projection radiographic images showed a soft tissue mass displacing the heart and the thoracic portion of the trachea.

Diagnosis and Treatment of a Swainson's Toucan () With Rhinosinusitis.

A female Swainson's toucan () was presented for examination with a 2-year history of mucoid nasal discharge and abnormal growth of the rhamphotheca. Nasal cytologic examination and culture results were consistent with mixed aerobic and anaerobic bacterial rhinitis. Radiographic and computed tomographic imaging demonstrated a deviated septum of the nasal diverticulum and multiple soft tissue densities in the caudal aspects of the maxillary and mandibular infraorbital diverticula of the infraorbital sinus.

Clinical features, treatment, and outcomes of cutaneous and oral squamous cell carcinoma in avian species.

OBJECTIVE To determine the clinical features, treatment, and outcomes of treatment for oral and cutaneous squamous cell carcinoma (SCC) in avian species. DESIGN Retrospective case series with nested cohort study. ANIMALS 87 client-owned birds of various species with histologically confirmed SCC of the skin or oral cavity.

Disease transmission from companion parrots to dogs and cats: what is the real risk?

A number of common misconceptions exist regarding the degree of transmission from companion parrots to dogs and cats. Concern regarding bacterial, viral, fungal, and parasitic transmission is generally unfounded, because disease transmission between companion parrots and dogs and cats is not well-documented. Infections with Mycobacterium spp, Aspergillus spp, Giardia spp, Chlamydophila psittaci, Salmonella spp, Yersinia pseudotuberculosis, Cryptococcus neoformans, Histoplasma capsulatum, Cryptosporidium spp, and avian influenza are often considered possible transmissible diseases, causing pet caregivers unwarranted concerns.

Laboratory reporting accuracy of polymerase chain reaction testing for psittacine beak and feather disease virus.

Diagnostic assays that use polymerase chain reaction (PCR) methods are increasingly available to veterinarians. Psittacine beak and feather disease virus (family Circoviridae, genus Circovirus) is a pathogen of clinical importance for which PCR assays have been developed. Several laboratories offer this diagnostic assay in the United States; however, there is little information on the sensitivity, specificity, or accuracy of these assays.
