CLONAL SPREAD OF 1B/O:8 IN MULTIPLE ZOO SPECIES.

(YE) bioserotype 1B/O:8 (YE 1B/O:8) was identified in routine culture of a variety of zoo species housed at Omaha's Henry Doorly Zoo and Aquarium (OHDZA) from April to July 2011. Animal cases representing 12 species had YE detected from 34 cases during routine fecal monitoring and/or during postmortem examination: Coquerel's sifakas (, two cases), black & white (BW) ruffed lemurs (, six cases), red ruffed lemurs (, seven cases), white handed gibbon one case), black lemurs ( three cases), mongoose lemurs (, two cases), African hunting dogs (, five cases), agile gibbons (, three cases), siamangs (, two cases), colobus monkey (, one case), argus pheasant (, one case), and orangutan (, one case). Most species were not symptomatic; however, three symptomatic cases in Coquerel's sifakas (two) and a white handed gibbon (one) showed clinical signs of diarrhea and lethargy that resulted in death for the Coquerel's sifakas.

Evaluating echocardiogram and indirect blood pressure results in male western lowland gorillas (Gorilla gorilla gorilla) during three phases of an anesthetic protocol.

Until the majority of the great ape population is trained for conscious cardiac evaluations, most individuals will require general anesthesia to perform echocardiograms. Within the veterinary community, concern exists that certain anesthetic protocols may exacerbate or artificially induce signs of cardiac disease. Because of potential cardiovascular effects, medetomidine has generally been used cautiously in patients with cardiac disease.

A novel case of Fusarium oxysporum infection in an Atlantic bottlenose dolphin (Tursiops truncatus).

A necropsy was performed on a captive-born, 10-yr-old male Atlantic bottlenose dolphin (Tursiops truncatus) after it died acutely. Gross necropsy findings revealed hemorrhage within the right cerebrum, right cerebellum, and right eye. Histopathologic findings revealed a moderate multifocal acute necrotizing meningoencephalitis with intralesional fungal hyphae.

Hypocitraturia in common bottlenose dolphins (Tursiops truncatus): assessing a potential risk factor for urate nephrolithiasis.

Numerous cases of urate nephrolithiasis in managed collections of common bottlenose dolphins (Tursiops truncatus) have been reported, but nephrolithiasis is believed to be uncommon in wild dolphins. Risk factors for urate nephrolithiasis in humans include low urinary pH and hypocitraturia. Urine samples from 94 dolphins were collected during April 2006 through June 2009 from 4 wild populations (n = 62) and 4 managed collections (n = 32).

Estimating bottlenose dolphin (Tursiops truncatus) hearing thresholds from single and multiple simultaneous auditory evoked potentials.

Hearing thresholds were estimated in four bottlenose dolphins by measuring auditory evoked responses to single and multiple sinusoidal amplitude modulated tones. Subjects consisted of two males and two females with ages from 4 to 22 years. Testing was conducted in air using a "jawphone" transducer to couple sound into each subject's lower right jaw.
