Dehydroepiandrosterone-sulfate (DHEAS) is the main steroid product of the primate fetal adrenal during mid to late gestation and it plays a major role in providing estrogens needed for parturition. We tested the hypothesis that this hormone can indicate fetal health status and attempted to use fecal DHEAS (fDHEAS) to predict pregnancy outcome in Japanese macaques. The subjects were 16 adult females and 3 neonatal Japanese macaques living in captivity at the Primate Research Institute, Kyoto University. We classified females that gave birth to healthy infants as successful and females that gave birth to dead infants as stillbirth (late fetal loss) and miscarriage (early fetal loss)...

BACKGROUND: Recent epidemics of highly pathogenic avian influenza (HPAI) produced an unprecedented number of cases in mute swans (Cygnus olor) in European countries, which indicates that these birds are very sensitive to the H5N1 virus. The HPAI outbreaks stirred a debate on the controversial stamping-out policy in populations of protected bird species. After preventive vaccination had been approved in the European Union, several countries have introduced vaccination schemes to protect poultry, captive wild birds or exotic birds in zoos against HPAI...

Peripheral nerve sheath tumors are a heterogeneous group of neoplasms that comprise neurofibromas, schwannomas, neurilemmomas, and perineuromas. In animals, peripheral nerve sheath neoplasms are most commonly diagnosed in dogs and cattle, followed by horses, goats, and cats, but their occurrence is uncommon in birds. An adult, free-living, male toco (common) toucan ( Ramphastos toco ) was admitted to the zoo animal clinic with weight loss, dehydration, and presence of a soft nodule adhered to the medial portion of the left pectoral muscle...

Banteng (Bos javanicus) are an example of a species of conservation concern without current "best practice" guidance, as they have been the focus of little applied husbandry research. Despite their elevated conservation status, and established, increasing global captive population, zoos do not yet have information on optimal husbandry. To help address this problem, a husbandry survey was distributed to all global holders of banteng. Questions focused on herd demographic structure, exhibit features (including mixed-species exhibition), dietary provision, and behavioral management...

Cell line establishment of somatic cells is a valuable resource to preserve genetic material of rare, difficult-to-find, endangered and giant species like Jaguar (Panthera onca), the largest South American felid. This unit focuses on the isolation and culture of fibroblasts from Jaguar skin and muscle biopsies, and ear cartilage dissection immediately after death to preserve one of the several endangered species in this biome. These culture techniques enabled us to contribute 570 samples from 45 autochthonous and endangered species, including Jaguar...

In this study, we examined cannibalistic behavior, growth, metamorphosis, and survival in larval and post-metamorph endangered yellow spotted mountain newts Neurergus microspilotus hatched and reared in a captive breeding facility. We designed a 2 × 2 factorial experiment, crossing two levels of food with two levels of density including high food/high density, high food/low density, low food/high density, and low food/low density. The level of cannibalistic behavior (including the loss of fore and hind limbs, missing toes, tail, gills, body damage, and whole body consumption) changed as the larvae grew, from a low level during the first 4 weeks, peaking from weeks 7 to 12, and then dropped during weeks 14-52...

In situ hybridization methods are used across the biological sciences to map mRNA expression within intact specimens. Multiplexed experiments, in which multiple target mRNAs are mapped in a single sample, are essential for studying regulatory interactions, but remain cumbersome in most model organisms. Programmable in situ amplifiers based on the mechanism of hybridization chain reaction (HCR) overcome this longstanding challenge by operating independently within a sample, enabling multiplexed experiments to be performed with an experimental timeline independent of the number of target mRNAs...

Wild bonobos (Pan paniscus), chimpanzees (Pan troglodytes), Western gorillas (Gorilla gorilla), and orangutans (Pongo pygmaeus, Pongo abelii) are threatened with extinction. In order to help maintain a self-sustaining zoo population, clinicians require a sound understanding of the diseases with which they might be presented. To provide an up-to-date perspective on great ape morbidity and mortality, a systematic review of the zoological and veterinary literature of great apes from 1990 to 2014 was conducted...

To assess Cryptosporidium infections among wild animals in a zoo located in Anhui province, we conducted an investigation on the fecal samples collected from 44 primates, 41 herbivores, 44 carnivores and omnivores, and 103 birds in the zoo with the use of Sheather's sugar flotation technique and modified acid-fast staining. Cryptosporidium oocysts were detected in the fecal samples from six primates, two herbivores, four carnivores and omnivores, and seven birds by using Sheather's sugar flotation technique; the prevalence of Cryptosporidium infection in primates, herbivores, carnivores and omnivores and birds was 13...

Iron overload disorder (IOD) is a significant health issue for captive black rhinoceros ( Diceros bicornis ). Measurement of serum ferritin with a validated rhinoceros ferritin ELISA has been used extensively to detect animals in U.S. zoos that are at risk of developing IOD. However, there is limited information on serum ferritin levels in free-ranging black rhinoceros using this same assay. Serum ferritin, iron, and gamma-glutamyl transpeptidase (GGT) were determined in 194 black rhinoceros from southern Africa...

Cardiac disease is a common condition in captive primates, and multiple cases in François' langurs ( Trachypithecus francoisi ) were noted on review of the Species Survival Plan studbook. To determine the prevalence of cardiac disease in this species, surveys were distributed to current and previous holding institutions (n = 23) for the U.S. studbook population (n = 216). After exclusion of stillbirths (n = 48), animals less than 1 yr of age (n = 8), and animals housed internationally (n = 2), a study group (n = 158) was identified for this analysis...

Skin diseases affect millions of people and animals worldwide, including Asian elephants. This study sought to determine the pathogen of skin diseases that occurred in Asian elephants in Chongqing Zoo, China. The isolated fungus was identified through its cultural characteristics, morphology, and polymerase chain reaction (PCR) amplification. The PCR amplification using common fungal primers (ITS1 and ITS4) determined that the pathogen was 99.7% homologous to Microsporum canis. This is the first report on elephants infected with Microsporum canis in China...

Coxiella burnetii, the causative agent of Q fever, can infect a wide range of host species, but limited information exists on the occurrence and implications of infection in wild species. This study describes a natural infection in a population of dorcas gazelles ( Gazella dorcas ) from a zoo. A 9-yr-old male Saharawi dorcas gazelle ( Gazella dorcas neglecta) tested positive on enzyme-linked immunosorbent assay (ELISA) and fecal polymerase chain reaction (PCR). Despite treatment with oxytetracycline, the animal did not clear the infection after 6 mo, as confirmed by a PCR test on a semen sample...

Hepatitis B virus causes horizontally transmitted infectious hepatopathy of primates and may progress to hepatocellular carcinoma. Historically, a small number of chimpanzees ( Pan troglodytes ) living in accredited North American zoos have been confirmed with positive hepatitis B serology consistent with exposure. However, the overall status for this population and the interpretation of these individual test results have not been established previously. The current U.S. zoo-housed population (n = 259) was assessed serologically for hepatitis B by surface protein antigen (HbsAg) and surface antibodies (anti-Hbs)...

Plant intoxications in wildlife are difficult to diagnose, are overlooked, or are sometimes even neglected. Hence, factors that induce wild animals to ingest poisonous plants have not been sufficiently documented. An outbreak of glycoprotein storage disease in sambar deer ( Cervus unicolor ), induced by ingestion of the swainsonine-containing plant, common wireweed (Sida carpinifolia), is reported. Nine out of 55 deer held by a zoo in Brazil were affected. The poisoning was characterized by emaciation and neurologic signs followed by unexpected death in some of the animals...

Diurnal primates typically give birth at night, when it is presumed that they are safer at a very vulnerable time, and this is reflected in an overwhelmingly nocturnal pattern of delivery in most species of Callitrichidae. However, over half (51.1%) of 88 births to pied tamarins (Saguinus bicolor) at Durrell Wildlife Park occurred during the day (0800-1700), almost always in the afternoon. Nearly three quarters of breeding females (17/23) had at least one diurnal birth, including females from all generations in captivity from wild-caught to fifth captive-born generation, and from all six matrilines represented at Durrell...

Generally speaking, southern Africa's wildlife populations in small-to-medium-sized protected game reserves (10,000-65,000 ha) reproduce at rapid rates which often lead overpopulation of certain species. Most commonly these are large predators such as lions, African wild dogs and cheetahs, and elephants. Overpopulation of large predators leads to depletion of prey species, breakouts into neighbouring communities and increased risks for disease transmission. An overabundance of elephants leads to habitat destruction which is to the detriment of not only other herbivores but also certain bird species...
