Polymeric immunoglobulin receptor (pIgR) mediates the transfer of polymeric immunoglobulin to protect organisms and is one of the most important mucosal effectors. In this study, the developmental stage- and tissue-specific expression of pIgR were observed before virus inoculation in olive flounder. pIgR was gradually expressed until the formation of immune tissue, exhibiting high expression in the late juvenile period; thereafter, pIgR expression gradually decreased and exhibited high expression in the spleen and skin. Moreover, pIgR expression after viral hemorrhagic septicemia virus infection was high in the kidney and spleen tissues at high density and low at low density. The results of this study can provide a basis for future studies on breeding density, virus expression, and immune system studies in fish.

본 연구에서는 넙치(Paralichthys olivaceus)로부터 분리한 바이러스성출혈성패혈증바이러스(viral hemorrhagic septicemia virus, VHSV, genotype IVa)에 대한 단클론 항체(monoclonal antibody, MAb)를 개발하였다. VHSV에 대한 항체를 생산하는 총 5개의 hybridoma clone을 생산하였다. 4개의 MAbs (2C10, 18H4, 23H6, 30B7)는 glycoprotein을 인식하였고, MAb 15E10은 nucleocapsid protein을 인식하였다. 5개의 MAbs는 western blot 상에서 VHSV에 감염된 세포와 넙치시료에 반응하였으나, 정상 세포와 넙치시료에는 반응하지 않았다. 또한 ELISA상에서 VHSV에만 반응하였고 6종의 어류바이러스(IHNV, HIRRV, SVCV, IPNV, MABV, NNV)에는 반응하지 않았다. 이상의 결과, 본 연구에서 제작된 MAbs는 VHSV에만 특이적으로 반응하는 것이 확인되어 VHSV를 검사하는데 사용될 수 있을 것으로 사료된다.

Vibrio unlnificus, a normal inhabitant in estuaries, is of great concern because it is a potent human pathogen causing septicemia, wound infection and gastrointestinal disease in Kum river, sampling was undertaken in five station from March, 26, 1993 to February, 22, 1994. Samples of 54 and 49 were collected from seawater and bottom deposit. The total detection rate of V. unlnificus was 11.7%. The detection rates of V. unlnificus in the seawater and the bottom deposit were 9.3% and 14.3% respectively. V. unlnificus was mainly detected in estuary water when temperature was above 23$^{\circ}C$ and salinity was below 15%. We suppose that water when temperature, salinity, pH and COD affect growth of V. unlnificus.

무지개송어(Salmo gairdneri)의 바이러스성 출혈성 패혈증에 관하여 연구하였다. 병어의 hematocrit값은 정상어보다 매우 낮게 나타났으며, GOT와 GPT값은 정상어보다 병어에서 약간 높게 나타났다. 병어의 혈청과 장기의 마쇄액을 CHSE-214세포에 감염시켜 세포변성 효과를 조사한 결과 감염 24시간 후에 세포변성이 나타났다.

birth-weight infants during the recovery phase of respiratory distress syndrome and has been associated with long-term pulmonary sequelae. The importance of surgical and medical abolition of left-to-right shunting in symptomatic neonates is established. Four preterm infants with birth weights under 1, 500gm with a PDA unresponsive to pharmacological closure underwent ligation. Two of preterm infants survived to be discharged and are developing normally. One infant has died due to respiratory distress syndrome, septicemia and necrotizing enterocolitis during hospital stay and other infant died due to septicemia after hospital discharge with follow-up for 6 months.

Two cases of sudden death without clinical signs in a four-month-old female Hanwoo (Bos taurus coreanae) and sixteen-month-old female Holstein (Bos taurus taurus) were investigated. Severe pneumonia and septicemia were found on postmortem examination. Petechial and ecchymotic hemorrhages were present in the subcutaneous tissues of the neck region. The lungs remained expanded without collapsing, and the mediastinal lymph nodes were enlarged. A significant number of hemorrhagic bubbles were present in the tracheal lumen. On histopathology, the alveolar blood vessels were moderately congested, and inflammatory cells and multinucleated syncytial cells were found in the alveolar space. The pathogen isolated from the lesion was identified as Bibersteinia trehalosi using MALDI-TOF and 16S rRNA gene and sodA gene sequence analyses. To the best of our knowledge, this is the first report of B. trehalosi infection in cattle in Korea.

Vibrio vulnificus is a gram-negative bacterium that can cause serious, potentially fatal infections. V. vulnificus causes three distinct syndromes: an overwhelming primary septicemia caused by consuming contaminated seafood, wound infections acquired when an open wound is exposed to contaminated warm seawater, and gastrointestinal tract-limited infections. Case-fatality rates are higher than 50% for primary septicemia, and death typically occurs within 72 hours of hospitalization. Risk factors for V. vulnificus infection include chronic liver disease, alcoholism, and hematological disorders. When V. vulnificus infection is suspected, appropriate antibiotic treatment and surgical interventions should be performed immediately. Third-generation cephalosporin with doxycycline, or quinolone with or without third-generation cephalosporin, may be potential treatment options for patients with V. vulnificus infection.

Group D streptococci are known to cause newborn septicemia and meningitis, but the Streptococcus bovis group strains rarely cause serious neonatal infections in Korea. Central nervous system (CNS) complications of neonatal S. bovis group infection have rarely been reported. In adults, S. bovis group strains cause bacteremia and endocarditis, and are associated with gastrointestinal malignancy. However, only a few studies have reported meningitis and septicemia in infants. Here, we describe a case of bacteremia and meningitis due to Streptococcus gallolyticus subsp. pasteurianus with a delayed CNS complication in an infant. A 28-day-old male infant was admitted to the hospital with a 1-day history of fever. Cultures of blood, cerebrospinal fluid, and urine showed the presence of S. bovis group strain-S. gallolyticus subsp. pasteurianus. He was discharged after 21 days of intravenous ampicillin and cefotaxime administration. Two weeks later, he was readmitted with a fever and short episodes of tonic-clonic movements. Brain magnetic resonance imaging showed marked bilateral frontal subdural effusion. He was discharged after 31 days of antibiotic therapy, and no neurological sequelae were observed at the 9-month follow-up. In conclusion, we present a rare case of neonatal S. gallolyticus subsp. pasteurianus infection causing urinary tract infection, septicemia, meningitis, and delayed CNS complications. This case emphasizes the need for physicians to be aware of S. bovis infection in infants.

우리나라 양식 넙치에서 분리한 VHSV (KR'01-1)의 glycoprotein 아미노산 배열을 기초로 단백질 전환 구조상 유연성, 친수성 및 항원성이 높고, 표면에 노출되어 있을 가능성(surface probability)이 높다고 분석되는 3개의 peptide (Gp1, Gp2, Gp3)를 선정하였다. 정제한 바이러스 입자 및 3개의 합성 peptide에 대한 polyclonal 항체를 제작하여 항원성 분석을 실시한 결과, 합성 peptide로 제작한 모든 항혈청은 Western blotting 결과 VHSV의 구조단백질과 특이적으로 결합하는 나타났으며, 이 가운데 Gp1 및 Gp2 합성 peptide에 대한 항혈청은 양식 넙치에서 분리한 VHSV를 중화시키는 것으로 나타나, peptide-based antigen의 이용 가능성을 제시하였다.
