INFECTIONS IN AN EASTERN RATSNAKE () AND A TIMBER RATTLESNAKE ().

This report describes infections in colubrid and viperid snakes. A captive eastern ratsnake () was presented for a large intraoral mass associated with the mandible. The mass was debulked and histologic examination revealed severe, granulomatous stomatitis with intralesional fungi exhibiting morphologic features consistent with .

Treatment of Recurrent Multifocal Cutaneous Squamous Cell Carcinoma in an African Grey Parrot () with Intralesional Carboplatin in Poloxamer 407.

A 16-year-old male Congo African grey parrot () was presented with an ulcerated wing mass that was excised and diagnosed on histopathology as squamous cell carcinoma (SCC). A second surgery was performed to completely excise the tumor margins, resulting in over 5 years of remission for the neoplasm. However, over the next 6 years the patient developed SCC in 3 new locations on the body, as well as 2 squamous papillomas.

Surgical Repair of a Complete Transverse Tracheal Rupture in a Mallard Duck ().

An adult male mallard duck () of unknown age was presented for acute intermittent respiratory distress that resolved when at rest. The duck had no history or evidence of trauma and had never been intubated. Radiographic imaging revealed a 1-cm tracheal defect at the level of the sixth vertebra.

A novel gammaherpesvirus found in oral squamous cell carcinomas in sun bears (Helarctos malayanus).

A novel herpesvirus was detected in sun bears (Helarctos malayanus) with oral squamous cell carcinoma. Five captive sun bears from 4 institutions in the United States presented with oral lesions ranging from erythema and mild erosions to nodular, ulcerated masses. All 5 were diagnosed with squamous cell carcinoma.

Characterization of basal seminal traits and reproductive endocrine profiles in North American river otters and Asian small-clawed otters.

In this study, fecal samples were collected from 24 North American river (NARO) and 17 Asian small-clawed otters (ASCO) for 6-36 months and semen collected seasonally from NARO males (n=4/season) via electroejaculation. Our main objectives were to: (1) characterize endocrine parameters by longitudinal monitoring of fecal hormone metabolites and (2) investigate semen collection and basal seminal traits in NARO. NARO demonstrated a distinct seasonality in the spring, with females having a monoestrual estrogen elevation lasting 15.

Gross and microscopic findings and investigation of the aetiopathogenesis of mycobacteriosis in a captive population of white-winged ducks (Cairina scutulata).

The white-winged duck (Cairina scutulata) is critically endangered. Breeding collections of this duck are established in the United Kingdom and the USA. Infection with Mycobacterium avium avium serotype 1 is a major cause of mortality in the UK collection.
