Leukemia and lymphoma account for more than 60% of deaths in captive koalas (Phascolarctos cinereus) in northeastern Australia. Although the endogenizing gammaretrovirus koala endogenous retrovirus (KoRV) was isolated from these koalas, KoRV has not been definitively associated with leukemogenesis. We performed KoRV screening in koalas from the San Diego(More)
During a preventive medicine examination on a 13-yr-old intact female African spot-necked otter (Lutra maculicollis), radiographs were obtained and a cranial thoracic mass was noted. Cytology from an ultrasound-guided fine-needle aspirate was suggestive of a thymoma. Surgical removal was performed and this diagnosis was confirmed by histopathology. At a(More)
Fluconazole is polar, soluble in water, and metabolically stable and exhibits low protein binding. In contrast, other systemic azoles are lipophilic, metabolically vulnerable compounds with high protein binding and negligible solubility in water. The physical and pharmacokinetic properties of these drugs plus their inherent antifungal potency determine(More)
Low, reproducible minimal inhibitory concentrations against Candida species, with sharp, precise end points in complex media were achieved for imidazoles (clotrimazole, econazole, miconazole, tioconazole and ketoconazole) and triazoles (fluconazole, itraconazole, vibunazole, ICI 153066) by including in the test medium antibacterial antibiotics that bind to(More)
A radiographic study documented shoulder dysplasia (n = 43), with varying degrees of malformation of the supraglenoid and infraglenoid tubercles and the coracoid process, shallowing or loss of the glenoid cavity, flattening or loss of the humeral head, malformation of the greater and lesser tubercles, loss of the intertubercle groove, and humeral diaphyseal(More)
Mycoplasma alligatoris was the suspected etiology of an epidemic of acute multisystemic inflammatory disease which emerged in captive American alligators (Alligator mississippiensis) in Florida (USA) in 1995. In an experimental inoculation study conducted from April through October 1999, 18 alligators were inoculated with 10(2), 10(4), or 10(6) colony(More)
A retrospective/prospective radiographic study documented 55 cases of moderate to severe hip dysplasia, with varying degrees of shallowing of the acetabulum, flattening or loss of the femoral head, widening or loss of the femoral neck, and femoral diaphyseal abnormalities in northern koalas (Phascolarctos cinereus) in the San Diego Zoo (San Diego,(More)
Koala retrovirus (KoRV) is a gammaretrovirus that has been identified in both captive and free-ranging koalas ( Phascolarctos cinereus ) with variable geographic distribution in Australia. KoRV is capable of both exogenous and endogenous transmission, which provides an interesting research platform for scientists to study active retrovirus endogenization(More)
A16-yr-old male koala (Phascolarctos cinereus) presented for nonspecific signs of illness and weight loss. Despite 2 mo of diagnostics and supportive care, the koala's health declined and euthanasia was elected. On histopathologic examination, lesions containing fungal organisms morphologically consistent with coccidioidomycosis were found in the lung,(More)
An outbreak of mycoplasmosis caused by Mycoplasma alligatoris resulted in the death or euthanasia of 60 American alligators (Alligator mississippiensis) from a population of 74 captive bull alligators in Florida in 1995. The natural reservoir, routes of transmission, and host range of M. alligatoris are unknown. This study was undertaken to determine(More)
