정지열,장현,Jung, Ji-Youl,Jang, Hyun 대한수의학회 2012 大韓獸醫學會誌 Vol.52 No.3
Actinobacillus (A.) pleuropneumoniae is the causative agent of pleuropneumonia which is one of the most important respiratory diseases in pigs worldwide. A total of 32 A. pleuropneumoniae isolates from diseased pigs during 2008 to 2010 were serotyped by polymerase chain reaction method. The susceptibility of the isolates to 13 antimicrobial agents were determined by disk diffusion test. In all the 32 isolates examined in this study, serotype 5 (16 isolates: 50%), 1 (7 isolates: 21.9%), 2 (5 isolates: 15.6%) and 12 (1 isolate: 3.1%) were found. Of all tested antimicrobial agents, resistance to oxytetracycline was found in 96.9% of isolates, followed by resistance to amikacin (81.2%), neomycin (68.7%), kanamycin (53.1%), penicillin (50.0%), gentamicin (43.7%), florfenicol (25.0%), ampicillin (18.7%), colistin (9.4%), trimethoprim/sulfamethoxazole, ceftiofur (8.3%), amoxicillin/clavulanic acid (3.1%) and enrofloxacin (0%). Oxytetracycline or florfenicol-resistant isolates were examined for the presence of resistance gene. Among the 31 oxytetracycline-resistant isolates, tetB, tetH and tetO genes were detected in 22 (71%), 8 (26%) and 1 (3%) isolates, respectively. The floR genes were detected in 8 (100%) of the 8 florfenicol-resistant A. pleuropneumoniae isolates.

An abnormally enlarged right ovary and a mass in fat surrounding the right kidney were discovered in a dairy cow during routine postmortem examination at slaughter. The ovary was dark reddish and multinodular in shape. Numerous cystic structures were identified in the mass. Histopathologically, the ovary was completely replaced with large, uniform, polyhedral neoplastic cells containing vesicular nuclei and prominent nucleoli. The mitotic index was high. In the lymphatic vessels, tumor emboli were observed. Another mass in the fat surranding the right kidney had the same histological features as the ovarian mass. This animal was diagnosed with malignant dysgerminoma and metastasis to other peritoneal organs.

Granulomatous meningoencephalomyelitis (GME) is a sporadic, idiopathic, non suppurative inflammatory disease of the canine central nervous system. GME appears to have a worldwide distribution and to occur mostly in young to middle-age dogs of small breeds. A 6-year-old female mixed dog with wry neck, ataxia and rolling was submitted to the Cheju National University for diagnosis. Grossly, in the brain, cerebrospinal fluid was mildly increased and dilatation of the subarachnoid blood vessels was observed. Histopathologically, the lesions were characterized by perivascular cuffs of lymphocytes, various numbers of macrophages and plasma cells in the brainstem and cerebral white matter. Numerous granuloma composed of lymphocytes and histiocytes were scattered throughout the brainstem. Two malacic foci characterized by axonal swelling and gitter cell infiltration with hemorrhage were noted in the medulla oblongata and cerebellum. Special stains failed to demonstrate any infectious agents. Immunohistochemically, the infiltrated cells demonstrated strong positive reactions for CD3, a marker for T lymphocytes origin. Based on the clinical signs, histopathology, and immunohistochemistry, this case was diagnosed as GME in a mixed dog.

Porcine circovirus type 2 (PCV2) and porcine reproductive and respiratory syndrome virus (PRRSV) have been suspected to have immunosuppressive effects on pigs. To investigate the correlation between these virus infection and the lesions of lymph nodes including sub-mandibular and inguinal lymph node, 44 pigs (PCV2 single, n = 14; PRRSV single, n = 10; PCV2/PRRSV, n = 14; negative control, n = 6) were examined by histopathology and immunohistochemistry. Histopathologically, granulomatous lymphadenitis characterized by lymphoid depletion with histiocytic cells infiltration was observed in PCV-2 single and PCV-2/PRRSV group. Immunohistochemically, there were significant reduction of B and T lymphocytes in lymph nodes of these groups, while the number of macrophages was increased. In only PRRSV infected group, germinal center hypertrophy and lymphoid necrosis were observed. Immunohistochemically, the number of CD3+ T lymphocytes was slightly increased. Severe lymphocytic depletion in PCV-2 infection-related lymph nodes might be associated with producing immunocompromised state in pig. Comparing with PCV-2 infected group, PRRSV produced minor effects on the changes in immune cell population in the lymph nodes of pigs. PRRSV may increase susceptibility of the disease in pigs by disruption of the first defense lines in target organs, such as the alveolar macrophages in lungs.

Multiple enlarged submandibular nodules were discovered during a routine antimortem examination at slaughter in 3 dairy cows of 20-month-old. Grossly, submandibular nodules were firm, reddish, and oval in shape. On cut surface, multiple yellowish abscesses in the parenchyma were observed. Histopathologically, the nodules were characterized by severe diffuse pyogranulomatous inflammation and chronic fibrosis with multiple eosinophilic clubs of Splendore-Hoeppli material containing central bacterial colonies. Trueperella pyogenes was isolated from the lesions. This case was diagnosed as submandibular pyogranuloma caused by Trueperella pyogenes in slaughtered dairy cows in Korea.

Pneumocystis (P.) carinii is an opportunistic fungal pathogen of many animal species and human, which can cause fatal pneumonia in immunocompromised individuals. Three 100-day-old pigs with progressive atrophy, anorexia and respiratory distress were submitted to the Cheju National University for diagnosis. Grossly, the lungs were enlarged with rubbery consistency. Histopathologically, the lungs were characterized by diffuse interstitial pneumonia with thickening of alveolar septa due to infiltration of macrophages and lymphocytes. Alveolar lumens were filled with a foamy eosinophilic proteinaceous material in which numerous punctiform organisms. The organisms were demonstrated as P. carinii by Grocott-methenamine-silver staining and immunohistochemistry in lungs of two pigs. In our best knowledge, this is believed to be the first report of P. carinii pneumonia in pigs in Korea.

Porcine ear necrosis syndrome is characterized by erosive and ulcerative lesions at the margin or tip of the pinna. Three growing pigs of different ages exhibited retarded growth accompanied by reddening and necrosis of ear prior to death. Gross examination showed reddening, swelling, black discoloration, scaling, and variable-sized yellowish materials and edema in ear cross section. Microscopically, thrombosis, abscess, ulceration, epidermal hyperplasia, and dermal pyogranulomatous inflammation with an intralesional bacterial colony were observed. Staphylococcus hyicus was isolated in all pigs' ears and porcine reproductive and respiratory syndrome virus was detected by PCR and immunohistochemistry.

In this study, we describe a case of epitheliogenesis imperfecta (EI) observed in the fetus of Korean native cattle. The fetus had multifocal areas of skin defect, especially on the distal portions of the four limbs, and the affected areas were bright-red and glistening. Histopathologically, these areas were characterized by complete absence of squamous epithelium, infiltration of inflammatory cells into the dermis, atrophy of hair follicles, sebaceous and sweat glands. To the best of our knowledge, this is the first report of epitheliogenesis imperfecta in Korean native cattle.

Six to seven-month-old 10 beef calves in 140-head beef cattle farm in Gimpo-si, Gyeonggi-do were suffered from ataxia and astasia. Two of them were submitted to Animal and Plant Quarantine Agency for diagnosis in July 9, 2015. At necropsy, the radius and tibia of both calves showed irregular thickening and hemorrhage of the physis in addition to hemorrhage and disruption of trabeculae in metaphysis. Histopathologically the physis showed irregular tongues of cartilage remaining the metaphysis. Disorganization, hemorrhage and fibrosis were observed in metaphyseal and epiphyseal bones. The serum 25-hydroxyvitamin D3 (D3) and calcium levels were lower than normal range. In addition, the serum D3 levels in the other 9 calves of the same farm were lower than normal levels. Based on the pathological examination and serum chemistry measurements, we diagnosed this case as rickets caused by vitamin D deficiency in calves.
