The concept about zoo is changing from the animal exhibition which simply contained the animals to the ecological zoo which has the function of preserving the animal species. At the central point of maintaining such role, the basic principle called the animal welfare lies obviously. Korea has applied the animal welfare principles such as carrying out the enrichment in the zoos since 2003, but there has not been any institutional device to evaluate and examine the application of the animal welfare so far. This study aims to confirm the level of animal welfare in Korea and suggest a developmental direction. For the purpose of the study, 12 zoos in Korea were evaluated according to 68 evaluating categories. 'Five Principles of Animal Welfare' in the Secretary of State's Standards of Modern Zoo Practice were selected and carried out as the evaluation categories, and the result, from the highest to lowest score given, was 'provision of food and water', 'provision of protection from fear and distress', 'provision of health care', 'provision of an opportunity to express most normal behaviours', and 'provision of a suitable enrichment' with the overall score of the entire Korean zoos being 2.86 (± 0.56). It was also confirmed that in order to improve the animal welfare of the Korean zoos, the animal management system must be standardized and organized. The evaluation and feedback, the active practice of animal welfare and its legislative support should be provided to establish an effective institutional device as well.

Hematologic reference values were determined for a captive population of 11 Mexican wolves (Canis lupus baileyi). Wolf pups from 4 to 24 weeks old had progressive age-related increases in PCV, hemoglobin concentration, mean cell volume, and RBC counts similar to those seen in domestic dog pups (C familiaris). Hematologic indices in wolves older than 24 weeks were comparable to those of the adult domestic dog; however, PCV, hemoglobin concentration, and RBC counts were higher.

Dermatophytosis was found on the right front leg of a 4-month-old female African lion cub (Panthera leo) kept at a zoo with locally marginal alopecia. For diagnosis, culturing on sabouraud dextrose agar was performed and skin scrapings from the lesion were analyzed. The ones from the culture and skin scrapings were identified as Trichophyton mentagrophytes. A zookeeper that had been in contacted with the lion for artificial rearing developed skin lesions with well-defined erythematous plaques on the right arm about 1 month after the lesion in the lion was observed. The ringworm was probably transmitted from the lion through continuous contact.

In this study, the enteric parasites of zoo animals and zookeepers in Beni-Suef governorate, Egypt were investigated. Fecal samples from thirteen animal species were examined by floatation and formol ether sedimentation techniques. Zoo animals were classified into non-human primates, carnivores and herbivorous animals. The examination of non-human primates revealed the presence of Trichuris trichura eggs, Giardia intestinals and Entamoeba histolytica cysts. In carnivores, Toxoascaris leonina eggs and Isospora felis oocysts were the most predominant findings. In herbivore wild animals, gastrointestinal nematode (GIT) eggs and Eimeria species oocysts were present. Larval identification by fecal culture of (GIT) eggs demonstrated the presence of Haemonchus contortus and Strongyloid papillosus larvae. Examination of zookeepers and one lab worker revealed the presence of Giardia intestinals and Entamoeba histolytica cysts. In conclusion, infection with Giardia intestinals and Entamoeba histolytica in both of human and nonhuman primates suggests the zoonotic transmission in the zoo.

The circulation and infection of avian influenza virus (AIV) in zoos and backyard flocks has not been systematically investigated. In the present study, we surveyed the birds including those in live bird markets (LBMs) and evaluated co-circulation of AIVs among them. Overall, 26 H9N2 AIVs and one H6N2 AIV were isolated from backyard flocks and LBMs, but no AIVs were isolated from zoo birds. Genetic analysis of the HA and NA genes indicated that most of the H9N2 AIVs showed higher similarities to AIVs circulating in domestic poultry than to those in wild birds, while the H6N2 AIV isolate from an LBM did to AIVs circulating in migratory wild birds. In serological tests, 15% (391/2619) of the collected sera tested positive for AIVs by competitive-ELISA. Among them, 34% (131/391) of the sera tested positive for AIV H9 antigen by HI test, but only one zoo sample was H9 positive. Although AIVs were not isolated from zoo birds, the serological results indicated that infection of AIVs might occur in zoos. It was also confirmed that H9N2 AIVs continue to circulate and evolve between backyard flocks and LBMs. Therefore, continuous surveillance and monitoring of these flocks should be conducted to control further epidemics.

Captive birds in zoological settings often harbor parasites, but little information is available about the potential for free-ranging avifauna to act as a source of infection. This review summarizes the gastrointestinal parasites found in zoo birds globally and in seven common free-ranging avian spe¬cies [mallard (Anas platyrhynchos), Eurasian blackbird (Turdus merula), common starling (Sturnus vulgaris), Eurasian jackdaw (Corvus monedula), house sparrow (Passer domesticus), European robin (Erithacus rubecula), and rock dove (Columba livia)] to identify the overlap and discuss the potential for cross-species transmission. Over 70 references were assessed, and papers spanned over 90 years from 1925 to 2019. A total of 60 studies from 1987 to 2019 met the eligibility cri¬teria. All examined free-ranging avifauna harbored parasite species that were also reported in zoo birds, except for the European jackdaw. Parasites reported in captive and free-ranging birds include nematodes (Capillaria caudinflata, Dispharynx nasuta, Ornithostrongylus quadriradiatus, Strongyloides avium, Syngamus trachea, and Tetrameres fissispina), cestodes (Dicranotaenia coronula, Diorchis stefanskii, Fimbriaria fasciolaris, and Raillietina cesticillus, Sobolevicanthus gracilis), trematode (Echinostoma revolutum), and protozoa (Cryptosporidium baileyi). Although no study effectively proved cross-transmission either experimentally or by genetic analysis, these parasites demonstrate low host specificity and a high potential for parasite sharing. There is potential for parasite sharing whenever determinants such as host specificity, life cycle, and hus¬bandry are favorable. More research should be carried out to describe parasites in both captive and free-ranging birds in zoological settings and the likelihood of cross-infection. Such information would contribute to evidence-based control measures, enhancing effective husbandry and pre¬ventive medicine protocols. [J Adv Vet Anim Res 2020; 7(3.000): 482-500]

The management of wild animals generally requires chemical containment with the use of sedatives, tranquilizers, general anesthetics or dissociative drugs. The spectacled bear (Tremarctos ornatus) is the only member of the family Ursidae characteristic of South America. There are few reports on the main anesthetic protocols used in this specie. The aim of the present study was to report the use of propofol and isoflurane in a captive spectacled bear, after sedation with tiletamine-zolazepam. A male bear approximately 15 years old and 264 lb (scale weight) underwent anesthesia for treatment of a recurrent ulcerated wound on the neck. A combination of tiletamine and zolazepam injected intramuscularly was initially used. Due to the need to prolong the anesthetic time, the decision was made to administer propofol 1% (4.0 mg/kg/IV), which proved satisfactory regarding the inhibition of eyelid and laryngotracheal reflexes, thereby facilitating tracheal intubation. The subsequent use of isoflurane provided adequate maintenance of anesthesia, with vital signs within the normal range for the species, but there was hyperthermia. Based on the present findings, the use of tiletamine/zolazepam, propofol and isoflurane proved satisfactory and the doses employed were safe for the spectacled bear (Tremarctos ornatus). Inhalation anesthesia was essential to prolonging the time and maintaining safety throughout the procedure.

Medical records from 860 pigeons and doves of 24 species housed in Bristol Zoo Gardens and Wild Place Project, United Kingdom, from 2000 to 2017 were reviewed to determine the causes of morbidity in captive columbiformes. Accounted 205 cases (51.25%), infectious disease was found as the primary cause of morbidity, followed by 133 cases of trauma (33.25%), 51 (8.9%) cases of non-infectious disease, and 8 (2%) cases of husbandry-related problem. The main cause of infectious disease was parasite infection with 35% over 31% of bacterial, 26% of undetermined etiology and 9% of fungal infection. More specific, nematodiasis was the most frequent parasitic disease found, presented in 49 (69%) cases and followed by 10 (14%) trichomoniasis of all parasite infection. Meanwhile, chlamydiosis was a leading cause of bacterial infection with 22 (35%) cases recorded of over 63 bacterial infections. These results highlight the importance of preventative medicine implementation in captivity which aims to detect the disease earlier hence reducing the worsening physical condition and minimising the risk of both zoonotic and non-zoonotic disease transmissions. In addition, these findings contribute to the limited information available regarding the captive columbiformes morbidity
