배경: 패혈증 환자의 예후를 예측하는 데 현재 사용되고 있는 임상적 채점 방식은 몇가지 제한점이 있다. 그래서 단백질체학(proteomics) 기법을 사용하여 표지자(proteomic biomarkers)를 찾으려 연구를 진행하였다. 방법: 본 연구에서는 16명의 패혈증환자에게서 중환자실에 입원하자마자 혈장을 채취하였다. 패혈증의 예후를 예측할 수 있는 표지자를 찾기 위해 Surface-enhanced laser desorption/ionization time-of-flight (SELDI-TOF) mass spectrometry를 사용하였다. 결과: 사망환자와 생존환자 사이에 통계적으로 유의한 차이가 있는 6개의 단백표지자를 발견하였고 이들은 패혈증 환자의 예후 예측과 치료계획수립에 도움이 될 것으로 생각된다. 결론: 프로테오믹 마커는 패혈증 환자의 예후를 예측하고 치료계획을 세우는 데 있어 유용하게 이용될 가능성이 있을 것으로 사료된다. Background; Several clinical scoring systems are currently being used to predict the outcome of sepsis, but they all have certain limitations. Therefore, we sought to identify the proteomic biomarkers, with wsing proteomic tools, that differed according to the outcome of sepsis patients. Methods; Upon admission to the ICU, blood samples were obtained from the 16 patients with sepsis who were enrolled in this study. Surface-enhanced laser desorption/ionization time-of-flight mass spectrometry (SELDI-TOF MS) was used to identify the markers that could predict the outcome of sepsis. Results; We found six peaks, by using cation and anion chips, that statistically differed between those patients who died and those who survived. Conclusion; The biomarkers we found by using proteomic tools may help predict the prognosis and also plan the treatment of sepsis. (Tuberc Respir Dis 2006; 61: 41-45)

This study surveyed for the prevalence of parasites, bacteria and viruses in four fish species, olive flounder (Paralichthys olivaceus), red sea bream (Pagrus major), black sea bream (Acathopagrus schlegeli) and black rockfish (Sebastes schlegeli) in 2010. The survey was aimed to compare the pathogens detected from wild and cultured fish for an epidemiological study. Anisakis sp. was predominantly detected from wild olive flounder and red sea bream (58.6% and 41.7% respectively), but not from the cultured fishes, suggesting anisakid infection is rare in cultured fish. The wild fish get in contact with the anisakids through their prey such as small fishes or crustaceans which carry the anisakids; whereas the cultured fish are fed with formulated feed, free of anisakids. Bacterial detection rates from the wild fishes examined in the study were lower than those of cultured fishes. Vibrio sp. dominated among detected bacterial population in cultured olive flounder (18%). Since vibriosis is known as a secondary infection caused by other stressful factors such as parasitic infections, handling and chemical treatment, it seems that cultured olive flounder are exposed to stressful environment. Viruses diagnosed in the study showed difference in distribution between wild and cultured fishes; hirame rhabdovirus (HRV) (0.1%) and lymphocystis disease virus (LCDV) (3.9%) were detected in the cultured olive flounder, but not in the wild fish, and marine birnavirus (MBV) (1.7%) and red sea bream iridovirus (RSIV) (3.2%) were detected from the wild and cultured red sea bream, respectively. From the survey conducted, it can be concluded that even though some pathogens (Trichodina sp., Microcotyle sp., etc.) are detected from both the wild and cultured fish, pathogens such as Anisakis sp., Vibrio sp. and LCDV showed difference in distribution in the wild and cultured host of same fish species and this can be attributed to their environmental condition and feeding.

넙치 병원성 세균에 대한 항균제 내성율과 다제내성을 조사하고자 연구를 수행하였다. 우리나라의 양식 넙치 (Paralichthys olivaceus)에서 161균주가 분리되었고 분리균주에는 Edwardsiella tarda (n=32), Vibrio ichthyoenteri (n=37), Vibrio spp. (n=54), Streptococcus parauberis (n=28) 그리고 Streptococcus spp. (n=10)가 포함되었다. E. tarda 분리균주는 tetracycline (84.4%)과 oxolinic acid (71.9%)에 높은 내성율을 나타내었고 V. ichthyoenteri와 Vibrio spp.는 ampicillin(94.6%, 81.5%)과 tetracycline (56.8%, 42.6%) 순서로 높은 내성율을 나타내었다. S. parauberis 분리균주는 ampicillin (57.1%), tetracycline (57.1%), erythromycin (35.7%) 순서로 높은 내성율을 보였다. E. tarda의 84.4%, V. ichthyoenteri의 73.0%, Vibrio spp.의 57.4%, S. parauberis의 42.8% 그리고 Streptococcus spp.의 70.0%가 2종류 이상의 항균제에 다제내성을 나타내었다. In this study, we carried out research on the level of single and multi-drug resistance of bacteria isolated from cultured flounder Paralichthys olivaceus. One hundred sixty one bacteria were isolated from cultured olive flounder Paralichthys olivaceus in Korea and the isolates consisted of Edwardsiella tarda (n=32), Vibrio ichthyoenteri (n=37), Vibrio spp. (n=54), Streptococcus parauberis (n=28) and Streptococcus spp. (n=10). These E. tarda isolates were highly resistant in the order of tetracycline (84.4%) and oxolinic acid (71.9%). V. ichthyoenteri and Vibrio spp. showed resistance ampicillin (94.6% and 81.5%) and tetracycline (56.8% and 42.6%). S. parauberis isolates were resistant ampicillin (57.1%), tetracycline (57.1%) and erythromycin (35.7%). Of the isolates, 84.4% of E. tarda, 73.0% of V. ichthyoenteri, 57.4% of Vibrio spp., 42.8% of S. parauberis and 70.0% of Streptococcus spp. isolates exhibited multi-drug resistance against more than two antibiotics.
