  • 2005년 여름에 국내에서 사육되는 가물치에서 대량폐사를 수반하는 새로운 질병이 발견되었다. 감염 어류는 복부팽만과 항문 주위 출혈 이외의 특이한 외부 증상을 나타내지 않았으나 복부를 절개하면 많은 수의 백색 결절이 간, 비장 및 신장을 포함한 내부 장기에서 관찰되었다. 특히 내부 장기의 조직병리학적 관찰에서 granuloma가 관찰되었다. 이들 감염 어류에서 Gram 양성의 사상균이 분리되었다. 분리균은 Nocardia spp.와 non-Nocardia 균의 16S rRNA 염기 분석에 기초한 Nocardia 특이 primer를 사용한 PCR 방법으로 확인하였다. 이것은 어류에서 발생한 Nocardia 감염증의 국내 첫 사례이다.

  • Nocardia, aerobic members of the order of Actinomycetaceae, produces infections in human lung. Nocardial infection is associated with underlying diseases of immuno-suppression or treatment with corticosteroid. It is difficult to detect Nocardia by sputum examination or histologic sections and it has rarely been diagnosed by fine needle aspiration of the lung. We describe a case of pulmonary nocardiosis in a 72 year-old man, diagnosed by fine needle aspiration, which was confirmed by culture of aspirates. The aspirates showed neutrophil-predominant inflammatory cells with microorganisms demonstrated by Gomori methenamine silver and Gram stain. The organisms had characteristic long blanching filamentous structures. The lesions on chest X-ray were in resolution with antimicrobial therapy.

  • Snakehead, Channa argus were intraperitoneally infected with Nocardia seriolae. at the concentrations of $1.5{\times}10^7cfu/m{\ell}$ or $1.5{\times}10^8cfu/m{\ell}$. The infected fish were kept in aquaria at $25^{\circ}C$ and $30^{\circ}C$ for 3 weeks. Clinical signs and mortality were monitored daily to evaluate the virulence. All artificially infected fish showed the same clinical sign found in naturally infected fish. All the fish infected with $1.5{\times}10^8cfu/m{\ell}$ of N. seriolae died within 24days. N. seriolae showed higher virulence to snakehead at the temperature $30^{\circ}C$. Internal lesions such as whitish nodules in the infected internal organs were not correlated with mortality but some degenerative changes were observed in all the infected organs within a week. Whitish nodules in the infected organs which are the typical character in nocardial infection was initially found at two weeks after the artificial infection in snakehead.

  • The majority of Nocardial infections reported in North America areIN. ;asteroides while those in Latin America are N. brasiliensis species. Infection with N. brasiliensis, to our knowledge, has not previously been reported in Korea. The auther isolated one strain of Nocardia brasiliensis from the abscess of right bottock of 23 month old female leukemic patient who was treated with methotrixate for five months at the Seoul National University Hospital. The morphological characteristics and biological properties were similar with the R.E. Gordon's description. The results are summarized as follow: 1. After 5 days incubation on Sabouroud's glucose agar, the acid fast character appeared partially. 2. Tyrosine, casein and urea were decomposed by 7 days incubation both at room temperature and at $37^{\circ}C$. 3. Sod, citrate and sod. acetate were utilized at $22^{\circ}C\;and\;37^{\circ}C$ after 28 days incubation while the sod. benzoate utilization was negative. 4. The survival range of temperature was from $10^{\circ}C\;to\;40^{\circ}C$. 5. Dulcitol, galactose, glycerol, lactose, maltose, mannitol, raffinose, rhamnose, sorbitol, trehalose and xylose fermentations were not observed up to 28 days, while the fermentation of glucose and inositol were positive.
