Cutaneous mast cell tumor and mastocytosis in a black-masked lovebird (Agapornis personata).

A 12-year-old female black-masked lovebird (Agapornis personata) with a cobalt color mutation was presented for self-mutilation of a mass located on the right lateral neck. Cytologic evaluation of the soft tissue mass revealed a predominance of poorly stained mast cells with metachromatic intracytoplasmic granules. The presumptive diagnosis was cutaneous mast cell tumor.

Bilateral hydronephrosis secondary to endometriosis managed by endoscopic ureteral stent placement in a captive Guinea baboon (Papio papio).

Spontaneous endometriosis is an estrogen-dependent, progressive and painful disease that affects a variety of nonhuman primates, including several species of baboons (Papio sp.). This case documents multimodal management of severe endometriosis in a captive female baboon within a zoological institution.

Hematology and clinical chemistry values of free-ranging basilisk lizards (Basiliscus plumifrons) in Costa Rica.

Twenty-three lizards were captured for this study, both males and females (12 males, 10 females, 1 undetermined), with a large range in body weights (40-286 g) appeared to be healthy based on activity level, physical examinations, and body condition scores. Heparinized blood samples from 20 free-ranging basilisk lizards (Basiliscus plumifrons) in Costa Rica were used for determining complete blood cell counts, plasma, and heparinized whole blood biochemical analysis. This information will serve as baseline reference data for future health assessment studies of free-ranging and captive basilisk lizards, as well as epidemiologic, conservation, and captive-breeding studies.

Analgesic efficacy and respiratory effects of butorphanol and morphine in turtles.

Objective: To test the hypothesis that butorphanol or morphine induces antinociception with minimal respiratory depression in conscious red-eared slider turtles.

Design: Prospective crossover study.

Animals: 37 adult male and female red-eared slider turtles (Trachemys scripta).
