BLOOD FATTY ACID PROFILES IN CHILEAN () AND CARIBBEAN () FLAMINGOS IN MANAGED CARE.

Flamingos in managed care are vulnerable to inflammatory states, including pododermatitis, trauma, and capture myopathy. Fatty acids are an important component of well-balanced nutrition and crucial to endogenous immune responses associated with these conditions, yet fatty acids have not been assessed in flamingos. This study reported complete whole blood circulating fatty acid profiles in two flamingo species in managed care receiving different diets.

A novel herpesvirus from a wild-caught Madagascar spider tortoise shows evidence of host-viral coevolution with a duplication event in .

Herpesviruses can be significant reptile pathogens. Herpesviral infection in a wild-caught, male spider tortoise () under human care was detected during a routine wellness examination prior to transition between zoologic organizations. The tortoise had no clinical signs of illness.

RETROSPECTIVE REVIEW OF UROLITHIASIS-RELATED MORBIDITY AND MORTALITY IN ASIAN COLOBINE MONKEYS.

Obstructive and incidental urolithiasis cases were evaluated in 5 Asian colobine monkey species (= 21 individuals) that included 12 silvery langurs (), 6 spectacled langurs (), 1 Javan langur (), 1 François' langur (), and 1 red-shanked douc langur () from eight zoologic institutions. All institutions that responded were Association of Zoos and Aquariums, European Association of Zoos and Aquaria, or World Association of Zoos and Aquariums accredited. Males were more commonly represented in the total number of cases (86%), and all cases of obstructive urolithiasis occurred in males.

MORTALITY REVIEW FOR THE NORTH AMERICAN SNOW LEOPARD () ZOO POPULATION FROM JANUARY 1999 TO DECEMBER 2019.

The objective of this 20-yr retrospective study was to review and summarize causes of mortality in the North American (NA) snow leopard population to inform and enhance animal health and husbandry practices. Pathology reports were requested from all NA zoological institutions housing snow leopards that died between 01 January 1999 and 31 December 2019. Data were reviewed and cause of death (COD) and concurrent diseases were summarized and compared by age group, organ system, and disease process.

Operative Vaginal Birth of a Critically Endangered Gorilla With Forceps Assistance.

Background: An obstetrician on standby assessed an 18-year-old primiparous captive gorilla with a term singleton fetus with a protracted labor course.

Case: After it was determined that an arrest of descent had occurred, a viable, 2,280 g male neonate was delivered through an operative vaginal birth with forceps assistance without major complications.

Conclusion: Given the numerous anatomic and biochemical similarities of humans and other great apes, it is possible that the high maternal mortality and stillbirth rates of gorillas could be reduced by using the same principles of obstetric management in a multidisciplinary fashion.

REVIEW OF CANINE DISTEMPER VACCINATION USE AND SAFETY IN NORTH AMERICAN CAPTIVE LARGE FELIDS (PANTHERA SPP.) FROM 2000 TO 2017.

Data on canine distemper virus (CDV) vaccination were collected on 812 large felids (351 tigers, ; 220 lions, ; 143 snow leopards, ; 50 leopards, ; and 48 jaguars, ) from 48 institutions to assess vaccine use and safety. The documented individual vaccination events with multiple products numbered 2,846. Canarypox-vectored CDV vaccines were the most commonly used vaccines (96.

RED PANDAS' () SEROLOGICAL RESPONSE TO CANARYPOX-VECTORED CANINE DISTEMPER VACCINES.

Red pandas () are susceptible to canine distemper, with a number of reported vaccine-induced canine distemper cases. Canarypox-vectored recombinant canine distemper vaccines (PureVax Ferret Distemper [PFD] and Recombitek CDV [rCDV]) provide protection without inoculating a live distemper virus, but there are currently no published data regarding these vaccines' safety and efficacy in red pandas. One hundred twenty-two serum samples were collected from 50 captive red pandas and analyzed for antibodies to canine distemper.

THE PASSAGE AND DURATION OF ANTIBODIES TO WEST NILE VIRUS IN HUMBOLDT PENGUINS (SPHENISCUS HUMBOLDTI).

West Nile virus (genus Flavivirus) outbreaks and mortality events have been documented in both wild and captive avian species, including penguins. Serologic response to vaccination in avian species has varied and appears to be largely species dependent; however, Humboldt penguins ( Spheniscus humboldti ) previously showed excellent rates of seroconversion. The goal of this study was to determine virus neutralization titers of 17 Humboldt penguin hens and their subsequent eggs, chicks, or both following vaccination with a killed West Nile vaccine.

VORICONAZOLE TOXICITY IN MULTIPLE PENGUIN SPECIES.

Aspergillosis is a common respiratory fungal disease in penguins managed under human care. Triazole antifungal drugs, including itraconazole, are most commonly used for treatment; however, itraconazole treatment failures from drug resistance are becoming more common, requiring newer treatment options. Voriconazole, a newer triazole, is being used more often.

Ophidiomyces ophiodiicola dermatitis in eight free-ranging timber rattlesnakes (Crotalus horridus) from Massachusetts.

Eight free-ranging timber rattlesnakes (Crotalus horridus) from two geographically isolated Massachusetts populations were observed with skin lesions located primarily on the head but occasionally also on the lateral and ventral surfaces of the body. The snakes underwent health assessments that included physical examination, clinical pathology, full body radiographs, and full thickness biopsies of skin lesions. Each snake had fungal elements present histologically in tissue sections from skin lesions.

Efficacy of treatment and long-term follow-up of Batrachochytrium dendrobatidis PCR-positive anurans following itraconazole bath treatment.

All anuran specimens in the Wildlife Conservation Society's collections testing positive for Batrachochytrium dendrobatidis (Bd) were treated with itraconazole and then studied after treatment to assess the long-term effects of itraconazole and the drug's effectiveness in eliminating Bd carriers. Twenty-four individuals and eight colonies of 11 different species (75 total specimens) tested positive for Bd via polymerase chain reaction (PCR) on multicollection survey. All positive individuals and colonies were treated with a 0.

Use of a Mycobacterium tuberculosis rapid lateral flow test for assessment of non-specific tuberculin responses in silvered langurs (Trachypithecus cristatus ultima).

Nonspecific responses to intradermal tuberculin skin testing (TST) have been frequently documented in silvered langurs (Trachypithecus cristatus ultima) at the Wildlife Conservation Society's Bronx Zoo. A commercial rapid lateral flow immunoassay (RT) for the identification of Mycobacterium tuberculosis and M. bovis antibodies was employed to assess this test's correlation with TST results and tuberculosis status.

Evaluation of medetomidine-ketamine-butorphanol anesthesia with atipamezole-naltrexone antagonism in captive male guanacos (Lama guanicoe).

Seven captive adult male guanacos (Lama guanicoe) weighing 112.0 +/- 10.9 kg (mean +/- standard deviation) were anesthetized with a combination of medetomidine (90.

Retrospective evaluation of idiopathic hematuria and associated pathology in Grant's gazelles (Gazella granti): 10 cases.

Ten cases of hematuria in Grant's gazelle (Gazella granti) (two male and eight female) from five institutions were examined and the clinicopathologic data summarized. Five gazelles died spontaneously and five were euthanized. All gazelles had marked hematuria without pyuria.

Seroprevalence of retrovirus in North American captive macropodidae.

Laboratory records of serology results from captive macropodidae sampled between 1997 and 2005 were reviewed to assess the seroprevalence of retrovirus exposure. Serum samples from 269 individuals (136 males, 133 females) representing 10 species of macropods housed in 31 North American captive collections were analyzed for retrovirus antibody using an indirect immunofluorescent assay. The prevalence of positive antibody titers comparing male versus female, between species, between age groups, and among animals with identified parentage was examined by nonparametric statistical analyses.
