We investigated the prevalence of arthropod-borne viral diseases in a population free-ranging mantled howler monkeys (Alouatta palliata) Costa Rica 1998. Blood samples were opportunistically collected from anesthetized for another study. Serology was performed on 64 individuals to assess exposure this vesicular stomatitis virus, equine encephalitis viruses, Mayaro St. Louis yellow fever and dengue virus. The New Jersey serotype (VSV-NJ) only pathogen which tested positive (44% [28/64]). This...
The ability to safely and effectively manage reproduction is central the success of AZA captive-breeding programs. Although Wildlife Contraception Center routinely monitors contraceptive safety, there have been no studies that compare effects use separation males from females, other option for preventing reproduction. We used retrospective medical records pathology reports submitted by related facilities seven AZA-managed canid species assess rates uterine relative female reproductive life...
Abstract The ability of females to store sperm for extended periods in their reproductive tracts (termed long‐term storage, LTSS) has been reported across a diversity vertebrate taxa. evolutionary, ecological, and physiological significance LTSS is wide‐ranging includes the produce offspring when mates may be temporally scarce by way decoupling copulation from ovulation, inbreeding avoidance, generation maintenance genetic progeny. Among lineages, nonavian reptiles exhibit remarkable...
As husbandry practices have improved, safe and effective contraception for captive wildlife management has become a necessity. Melengestrol acetate (MGA), synthetic progestin, is highly been used in many zoo species. Long-term use of MGA associated with uterine lesions felids, but effects canids not evaluated. This retrospective study documented spontaneously occurring investigated the impact on reproductive health canids. Reproductive tracts from adult females were submitted by US zoos to...
Avian poxvirus (genus Avipoxvirus, family Poxviridae) is an enveloped double-stranded DNA virus that may be transmitted to birds by arthropod vectors or mucosal membrane contact with infectious particles. We characterized the infection in Anna's Hummingbird (Calypte anna; n = 5 birds, 9 lesions) conducting diagnostic tests on skin lesions were visually similar avian other bird species. Skin single multiple, dry and firm, pink yellow, scabs surface, located at base of bill, wings, legs....
Telazol® has been commonly used for field anesthesia of wild lemurs, including ring-tailed lemurs (Lemur catta). Telazol alone provides good induction, but doesn't cause adequate muscle relaxation and sedation collecting consistent somatic measurements high-quality dental impressions that are sometimes needed. Variability in induction response seen between individuals have received similar dosages, with young seeming to need more anesthetic than mature lemurs. This investigation evaluated...
Fledgling cliff swallows were cared for at a rehabilitation facility when clinical signs of ocular disease, characterized by conjunctivitis, epiphora, and hyperaemia palpebrae nictitans, recognized. Treatment consisted topical oral antibiotic therapy one steroid administration. However, swallow died three killed due to poor therapeutic response. Conjunctival swabs obtained ante-mortem from the submitted mycoplasma culture molecular diagnostics. Heads birds fixed in 10% neutral buffered...
There is a growing need for animal care institutions to house multiple bull elephants as the population increases due transfers from private ownership and births of male offspring in managed care. Elephants North American, European, Latin American zoos exhibit stereotypies—repetitive, fixed behaviors. Previous research demonstrated that housing Asian alone increased stereotypic behavior. Therefore, animals care, social restriction can contribute stereotypy and, by extension, reduce welfare....
With the use of a crossover study design, we investigated respiratory and cardiovascular effects naloxone administration in eight healthy Rocky Mountain wapiti (Cervus elaphus nelsoni) anesthetized with carfentanil (10 μg/kg i.m.) xylazine (0.1 mg/kg). Anesthetized animals showed profound hypoxemia mild hypercapnia, tachycardia, hypertension, acidosis prior to administration. After monitoring equipment was placed, were administered either (2 μg/μg i.v.) or an equivalent volume normal saline....
This multi-institutional collaborative study of neoplasia in snakes reviewed medical records at each facility to determine species prevalence, survival, and methods treatment. Complete numbers were also collected facility. In total, 65 species, 133 snakes, 149 unique neoplasias included this study. Affected age, sex, their tumor type location, metastasis, treatment, survival data are reported. The highest species-specific prevalence was Common or Northern Watersnakes (Nerodia sipedon)...
Howler monkeys ( Alouatta spp.) are threatened by anthropogenic pressures such as habitat fragmentation and deforestation, while conservation efforts challenging to coordinate natural geographic distribution ranges the largest of any New World primate. On a One Health front, howler represent great model investigate infectious disease dynamics between wild primates humans several diseases affecting howlers have demonstrated zoonotic potential. monkey populations in professional care offer...
Abstract Background Hematologic and blood biochemical values are key tools for assessing primate health. A long‐term behavioral study of howler monkeys at a single site (La Pacífica, Guanacaste, Costa Rica), afforded the opportunity to develop baseline large group animals, evaluating differences between adult males females comparing report in same population two decades later. Methods In 1998, 64 free‐ranging mantled were anesthetized sampled hematologic analysis. Results Blood analysis is...
As evidenced by numerous case reports from zoos, neoplasia in felids is common, but most are limited to Panthera species North America or Europe. In order obtain a wider epidemiologic understanding of distribution, necropsy records at seven facilities (USA, Mexico, Colombia, Peru, and Brazil) were evaluated. contrast others, this study population (195 cases, 16 species), included many non-Panthera felids. Overall prevalence was 28.2% (55/195). had higher than (52.5%; vs. 13.0%). Lions...
Contraception is necessary to manage zoo animal populations and be able house animals in groups without producing additional unwanted offspring. In felids canids, an association between exposure progestins the occurrence of endometrial mammary gland pathology has been documented. Therefore, Association Zoos Aquariums (AZA) Wildlife Contraceptive Center recommends use deslorelin acetate for long-term contraception carnivores. Return cyclicity after treatment variable; some individuals show...
Male associations are a typical component of elephant society, allowing bulls to practice appropriate social behavior. To improve zoo welfare, it is important provide with opportunities. In fall 2018, Denver Zoo added two bull Asian elephants its existing all-male group three bulls, offering the opportunity conduct systematic behavioral study integration new into resident group. We recorded aggressive and affiliative behaviors before, during, after introduction males. The proportion behavior...
For over 25 years, the Reproductive Health Surveillance Program has collected, processed, evaluated, and archived reproductive tracts from nondomestic mammals submitted by zoos. The analysis of data this archive been used to recognize lesions associated with exposure certain contraceptives; but arguably more importantly, also document naturally occurring lesions. goals program are enhance management captive free-ranging species providing information about effects various contraceptives...
The efficacy, safety, and reliability of two ketamine-medetomidine-butorphanol anesthetic combinations were evaluated in 34 adult binturongs (Arctictis binturong). animals randomly assigned to one the groups. On basis estimated body weights, group high ketamine (HK) received (8 mg/kg, i.m.), medetomidine (0.02 butorphanol (0.2 i.m.) combined a single injection, low (LK) (2 (0.04 i.m.). Cardiopulmonary parameters measured for approximately 45 min; then administered atipamezole (5 mg/mg...
