A 12-year-old female Tammar Wallaby (Macropus eugenii) died after a 6-day history of depression, anorexia, and coughing. The necropsy revealed pustules of varying sizes on the lung surface from which a pure culture of Staphylococcus aureus was ioslated. Histopathologically, the pulmonary nodules formed typical granulomatous inflammation. The center of the granulomatous foci consisted of a necrotic center and grain particles with gram positive cocci that were surrounded by eosinophilic club-like bodies containing Splendore-Hoeppli material.

A 2-years-old female domesticated mouflon with a clinical history of chronic diarrhea and emaciation was submitted to NVRQS. Grossly, there were severe thickening of small intestine wall and enlargement of mesenteric lymph nodes. Microscopically, severe granulomatous inflammation was found in small and large intestine, mesenteric lymph nodes, spleen and liver. By Ziehl-Neelsen stain, innumerable acid-fast rod bacteria were found in the cytoplasm of epitheloid and Langhans type giant cells present in these organs.

Photo-catalytic products have been widely used at home and hospital to prevent bacteria, virus and fungus. Activities of anti-bacteria, anti-viruses and anti-fungi are based upon direct contact of crystals and particles of titanium dioxide with pathogens, into which titanium is catalyzed by phoo. Those antimicrobial activities of the photo-catalytic titanium dioxide have been proved in vitro. However, in vivo tests of those activities have not been carried out on dog skin. Aim of this study was to evaluate the antimicrobial activities of the catalytic titanium dioxide in vivo.

A stable and reliable Helicobacter pylori (H. pylori) infection animal model would be necessary for evaluating vaccine efficacy and helpful for understanding the pathological mechanism of the organism. The aim of the present study is to investigate the effect of ethanol treatment prior to H. pylori inoculation on associated gastric mucosal injury and to establish ethanol-pretreating animal model to study H. pylori infection. Male Mongolian gerbils were used for the study. H. pylori was orally inoculated after 12 h fasting.

Porcine reproductive and respiratory syndrome (PRRS) is an economically important disease of swine that occurs all over the swine industry worldwide. It was first observed in the Unite States in 1987 then in Europe in 1990. It has been described in Japan and in Korea in 1993. PRRS virus is divided into two distinct types, North American and European, genetically. Based on our limited knowledge there has been no report on the existence of European PRRSV. But according to the government's Korea Customs Service there has been many importations of breeding pigs from Europe.

A 2-month-old female Shih-tzu dog was referred because of lameness, exercise intolerance, depression, elbow and stifle joint swelling. Physical examination, complete blood counts, serum-chemistry, radiography, synovial fluid analysis, antinuclear antibody test, and rheumatoid factor measurement were initiated. On radiography, soft tissue swelling of elbow and stifle joints without erosiveness were founded. The results of synovial fluid analysis revealed severe neutrophilic pleocytosis (nondegenerative), decreased viscosity, increased turbidity, positive on mucin-clot test, and negative on bacterial culture.

Caudal occipital malformation syndrome (COMS) is relatively common disease which occurs at craniocervical junction. It has been known that this syndrome was developed mainly in Cavalier King Charles spaniels, but these days there a lot of case reports about COMS in other small breed dogs. In this report, COMS was diagnosed in ten dogs presented to Haemaru Referral Animal Hospital using MRI examination from January 2005 to April 2006. These cases were also investigated about concurrent diseases and syringomyelia was the most common type of complication, but clinical signs were nonspecific.

A 4-year-old male Miniature Pinscher was referred because of head tilt, nystagmus, and ataxia. The hemogram revealed a moderate neutrophilic leukocytosis. On magnetic resonance imaging, cerebellar inflammation was detected. And cerebrospinal fluid analysis indicated marked neutrophilic pleocytosis. Based on these results, bacterial meningoencephalitis was suspected. The clinical signs were well controlled by a combination antibiotics therapy of the third generation cephalosporins (cefotaxime and cefixime) and metronidazole.

This study was aimed to obtain the anatomical information on the location of ostia of left and right coronary artery in 3 weeks old and 6 months old hybrid swine. The each intercommissural distance of 6 months group was twice than 3 weeks old group. The largest sinus was right aortic sinus followed by left and posterior sinus. All left coronary artery ostia in left aortic sinus were located near the right aortic sinus as well as lower than the ostia of right one.

Generally known psittacosis or ornithosis is a disease of birds caused by the bacterium Chlamydia psittaci. Humans are accidential hosts and are most commonly infected from avian sources. It raises hepatitis or neurosis. As major outer membrane protein (MOMP) of Chlamydia psittai has been known to play a role in the avoidance of host immune defenses, research on developing a Chlamydia vaccine has focused on the MOMP. In this study, the gene encoding the major outer membrane protein (MOMP) of the Chlamydia psittaci strain 6BC was cloned and expressed in Escherichia coli Strain M-15.
