The present study was conducted to investigate biochemical characteristics and antimicrobial susceptibility of Aeromonas hydrophilia isolated from Jackass penguins (Spheniscus demersus) of zoo and capelins (Mallotus villosus). Seven of Jackass penguins showed anorexia, depression with seriously greenish vomiting for a few days, but resulted in 4 deaths although extensive treatment was carried out by zoo veterinarians. From the 18 samples composed of organs or feces from dead or live Jackass penguins and capelins, 4 (22.2%) Aeromonas hydrophilia were isolated and Bacillus spp, Staphylococcus aureus, Staphylococcus auricularis, Staphylococcus cohnii and Enterobacter aminigenus were also identified. Antimicrobial susceptibility tests of Aeromonas hydrophilia showed that all isolates were susceptible to amikacin, gentamicin, kanamycin, norfloxacin and trimethoprim- sulfadimethoxazole. However, all isolates were resistant to the following antimicrobials; ampicillin, bacitracin, c ephalothin, cefazolin, noboviocin, penicillin and vancomycin.

The chemical immobilization in giraffes (Giraffa camelopardalis reticulata) remains a challenge because of their size, behavior, and anatomic and physiologic characteristics that commonly create life threatening problems during immobilization. The drug combination medetomidine (MED) and ketamine (KET) was administered by remote injection. The dosages of MED and KET were correlated to the giraffe's shoulder height (SH), become recumbent with a dosage of $114{\mu}g$ of MED and 2.1 mg of KET, $320{\mu}g$ of atipamezole per cm of SH, respectively. After injection of the drugs, initial signs of sedation including ataxia were noticed at 3 minutes followed by lateral recombency at 12 minutes. The mean heart rate, respiratory rate and rectal temperature recorded during the procedures were 55 beats per minute, 48 breaths per minute and $36.6^{\circ}C$, respectively. Atipamezole was administered, after 33 minutes result in death. Assuming that 24 hours fasting times were short and light esteemed of atipamzole adverse effects like vomiting, passive regurgitation.

Aeromonas hydrophilia infection was diagnosed in captive Jackass penguins (Spheniscus demersus). Seven Jackass penguins showed clinical signs including depression and anorexia with greenish vomiting, but four penguins were died although extensive treatment was carried out. At necropsy, the penguins appeared to have hemorrhage and catarrhal inflammation of the small and large intestines and severe enlargement of the right hepatic lobe, elongation of the gall bladder and pyloric ulceration of the stomach. The ovaries observed atrophy and congestion. Microscopically, there were congestion, fat droplet within the cytoplasm of the hepatic cell, infiltration of lymphocytes in the stomach, vilous detachment and destroyed glandular epithelium in the small and large intestines. Aeromonas hydrophilia was isolated from the liver and small intestines. This case is the first report of an occurrence of Aeromonas hydrophilia infection at Jackass penguins in Korea.

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.

Outbreaks from September 1999 to July 2000 of blackleg in 4 milking and fatting cattle farms in the vicinity of Munkyong(northwestern part of Gyeongbuk province) were investigated biochemical characteristics of isolates and were surveyed epidemiological works during the period of 2 months from August to September 2000. Clostridium chauvoei, the etiological agent of blackleg is a serious pathogen of cattle and sheep causing fever, depression and lameness with high mortality in growing phase of 6 to 18 months old mainly beef cattle. Biochemical and cultural properties of 4 isolated Cl chauvoei were identical to those of reported results and isolates were susceptible to ampicillin, bacitracin, chloramphenicol, cephalothin, ciprofloxacin, erythromycin, norfioxacin, penicillin, and tetracycline, while they were resistant to amikacin, colistin, gentamicin, kanamycin, neomycin, streptomycin and trimethoprim-sulfamethoxazole. In the results of epidemiological survey, outbreak farms that concentrated region of milking or fatting cattle in each sites were so close contact within a radius of about 1km that they are separated only by wire fence or shrub barrier and flies, rodents, wild cats and birds could have the chance to move around between those farms. The origin of the outbreak blackleg were uncertain, but the transmission between farms were mainly through the movement of farm personnel, vehicles which were struck the feces or manures from farm and other mechanical factors such as flies, rodents and birds furthermore occurred mission between farms were mainly through the movement of farm personnel, vehicles which were struck the feces or manures from farm and other mechanical factors such as flies, rodents and birds furthermore occurred 4 farms were not vaccinated. In conclusion, a periodic disinfection, vaccination and quarantine prevention are ideal methods of damage reduction by blackleg.

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.
