A female reticulated giraffe (Giraffa camelopardalis), 20-month-old, 342 kg, died at Seoul Zoo on January 2, 2009 after a stressful episode of chronic diarrhea. Given the appearances postmortem, it was strongly suspected that the giraffe suffered from malnutrition for a long time. Typical appearances of serous fat atrophy were shown on most fat tissues of body organs such as heart, bone, liver, mesentery and kidney. In this study, the sudden death that had been known as "peracute mortality syndrome" was clearly identified to have resulted from a lack of understanding the Browser's diet and general failure in giraffe husbandry. Individualized care and high quality hay must be provided to compensate higher consumption of metabolic energy and to prevent animal loss in winter season.

Eighty-seven strains of Enterobacteriaceae isolated from feces of wild mammals in Choniu zoo were tested for their biochemical reaction and susceptibility to 19 antibiotics or chemicals by using disc diffusion test and/or Microscan Walkway 40/96. Out of 87 isolates, Enterobacteriaceae (44), Hafinia alvei (9), Citrobacterfreundi (5) and Proteus vulgaris (5) were frequently detected. The detective frequency of Enterobacteriaceae in animals classified by their eating pattern was higher in carnivorous and omnivorous than in herbivorous animal. In antibiotic susceptibility tests most of isolates were susceptible to cefazolinl ceftazidime, aztreoname, trimethoprin/sulfamethoxazole, gentamicin, ciprofloxacin, cofuroximel ceftriaxone, cefotaxime and eftizoximel and moderately susceptible to cephalotin and ticarcillin but resistant to ticarcillin/K and amikacin.

A three years old male Jackass penguin(Spheniscus demersus) showed anorexia, depression, respiratory problem for a few days, followed by clinical treatment for 20 days resulted in death. Grossly, multiple white nodules measuring 2~3 mm in diameter were observed in the surface of and inside lung, liver, kidney, thoracic wall. Microscopically, granuloma formations were observed in the lung and liver. The margin of granuloma surrounded by connective tissue barrier and infiltrated lymphocytes, and also observed giant cell near the granuloma. By Periodic acid Schiff reaction, hyphae were detected in granuloma of lung and liver. This case was a chronic and systemic aspergillosis caused by Aspergillus fumigatus infection in a Jackass penguin at a zoo.

Zoological Parks house exclusive animal species, thus creating a source of education and awareness for visitors. Big cats like tigers and leopards are among the most visited species in zoos globally. However, they often display stressful or stereotypic behaviours. Such behaviours are influenced by multiple factors including visitors, animal history, and captive environment. To understand this impact, we investigated the behavioural response of tigers and leopards to visitation, captive, and biological factors. The behaviour of eight big cats housed in the National Zoological Park, New Delhi, was monitored using focal sampling technique during May and June 2019. We recorded the captive and biological factors and visitor density for the subjects. The study revealed high proportions of inactive and stereotypic behaviours amongst the species. Tigers and leopards were found to perform stereotypic behaviours for 22% and 28% of their time, respectively. Generalised Linear Models revealed a significant variation of stereotypy in association with the factors. Stereotypy was influenced by visitor density, age, sex, breeding history, coat colour, and enclosure design. Adults, males, white-coated, previously bred, and those housed in smaller and simple enclosures display more stereotypy than young, females, normal-coated, unbred, and those housed in larger and complex enclosures, respectively. A high density of visitors induced more stereotypic behaviours amongst the big cats. As providing entertainment and awareness amongst the public is one of the fundamental objectives of the zoo, visitors can not be avoided. Thus, we suggest providing appropriate enrichments that would reduce stereotypies and promote naturalistic behaviours.

국내 수의학 분야에서 야생 및 동물원동물 (zoo and wild animal)의 질병은 주로 대단위 동물원에서 임상적인 측면에서 발전하여 왔으며, 일부 제한적인 분야이고 정밀 실험실 진단이 뒷받침되지 않은 예들이 많았다. 따라서 1990년 이후 서울대학교 수의과대학 및 국립수의과학검역원에 검사 의뢰된 야생동물 중 질병으로 판명된 예 들을 살펴봄으로써, 국내 야생 및 동물원동물 질병의 진단 및 치료에 다소나마 도움이 되고자 한다. (중략)

The purpose of this study firstly was conducted to establish a radioimmunoassay (RIA) of estrone sulfate ($E_1S$), secondly to monitor the reproductive status of dairy cows using their urine samples. Urine and blood samples were collected in series within a day from four pregnant Holstein-friesian cows to evaluate the relationship between $E_1S$ levels in blood and urine with or without urinary creatinine basis. The urine was then collected biweekly from three cows in estrous and those artificially inseminated; collection from pregnant cows was made on a monthly basis. Results indicated that sensitivity for the $E_1S$ RIA was 5 pg/tube and the recovery rate was 100%. The daily urinary creatinine concentrations fluctuated within a day, but changes were slighter in midday, whereas the changes of concentrations of $E_1S$ in urine were relatively smaller. The concentrations of serum $E_1S$ during the estrous cycle were undetectable due to the limitation of assay, but the urinary $E_1S$ level could be measured with no obvious changes during the cycle. The urinary $E_1S$ levels increased remarkably around 7.7 to 8.3 ng/ml, 80 to 100 days after pregnancy but the serum $E_1S$ levels did not elevate until 120 to 150 days. The level of $E_1S$ increased gradually during pregnancy and eventually reached its peak before parturition at around 40 ng/ml and finally decreased to its basal level 2 days postparturition. During pregnancy, $E_1S$ concentrations of urine increased earlier than those in blood. The correlation coefficients between urinary and serum $E_1S$ concentration during pregnancy and postparturm were higher than those adjusted with creatinine (creatinine ratio). The concentrations of $E_1S$ in urine could be maintained unchanged for 8 days storing the samples in room temperature, which was extended to 8 days when the samples were pretreated by boiling for 30 minutes or treated with autoclave. In conclusion urinary $E_1S$ concentrations can be used directly for monitoring the pregnant status and fetal viability of dairy cows and can assist accurate confirmation of pregnancy in cows at least 80 to 100 days after insemination much earlier than by serum $E_1S$.

A 7-year-old, female snow goose (Anser caerulescens hyperboreus) with history of decreased activity for 2 month died in Daejeon Zoo Land in September 2006. At necropsy, granulomatous pneumonia and hepatomegaly with multiple cysts were observed. Small masses were found in the spleen. Microscopically, fibrinous pneumonia distributed in most of the lung lobe with pulmonary edema and congestion. Especially, granulomatous inflammation with numerous multinucleated giant cells was observed around the dilated bronchi. To confirm the diagnosis, acid-fast (Ziehl-Neelsen method) and periodic acid-Schiff (PAS) staining was performed. Acid-fast staining showed red bacterial colony indicating tuberculosis. PAS staining was also positive enough to diagnose aspergillus spp. co-infection that was an opportunistic fungi occurring in immuno-compromised animals. Based on the above results, we confirmed that the case submitted was diagnosed as avian tuberculosis.

Sarcocystis sp. infection was investigated in 20 necropsied captive wild mammals and 20 birds in 2 petting zoos in Malaysia. The gross post-mortem lesions in mammals showed marbling of the liver with uniform congestion of the intestine, and for birds, there was atrophy of the sternal muscles with hemorrhage and edema of the lungs in 2 birds. Naked eye examination was used for detection of macroscopic sarcocysts, and muscle squash for microscopic type. Only microscopically visible cysts were detected in 8 animals and species identification was not possible. Histological examination of the sections of infected skeletal muscles showed more than 5 sarcocysts in each specimen. No leukocytic infiltration was seen in affected organs. The shape of the cysts was elongated or Circular, and the mean size reached $254{\times}24.5{\mu}m$ and the thickness of the wall up to $2.5{\mu}m$. Two stages were recognized in the cysts, the peripheral metrocytes and large numbers of crescent shaped merozoites. Out of 40 animals examined, 3 mammals and 5 birds were positive (20%). The infection rate was 15% and 25% in mammals and birds, respectively. Regarding the organs, the infection rate was 50% in the skeletal muscles followed by tongue and heart (37.5%), diaphragm (25%), and esophagus (12.5%). Further ultrastructural studies are required to identify the species of Sarcocystis that infect captive wild animals and their possible role in zoonosis.
