In order to detect quarantine plant viruses, we developed reverse transcription-polymerase chain reaction (RT-PCR) primer pairs for five single-stranded (ss)plant RNA viruses that are not currently reported in Korea but could be potential harmful plant viral pathogens. Three viruses such as Chilli veinal mottle virus (ChiVMV), Colombian datura virus (CDV), and Tobacco etch virus (TEV) belong to the genus Potyvirus while Chrysanthemum stem necrosis virus (CSNV) and Iris yellow spot virus (IYSV) are members of the genus Tospovirus. To design RT-PCR primers, we used reported gene sequences corresponding to the capsid protein and polyprotein for ChiVMV, CDV, and TEV while using nucleocapsid protein regions for CSNV and IYSV. At least two different primer pairs were designed for each virus. Fifteen out of 16 primer pairs were successfully applied in detection of individual quarantine virus with high specificity and efficiency. Taken together, this study provides a rapid and useful protocol for detection of five quarantine viruses.

보체계는 우리 몸에서 감염에 대한 초기 방어를 담당하는데 그중 후기 보체 성분의 결핍시 수막구균의 감염에 쉽게 노출된다. 특히 재발 감염된 수막구균 혈증 환자에서 보체계의 검사가 반드시 필요할 것으로 생각되는 바이다. 저자들은 재발성 수막구균 혈증으로 치료받은 환자에서 C7 결핍증을 경험하였기에 이를 보고하는 바이다. The complement system is important in the generation of the normal inflammatory response and in host defense against systemic infection. Therefore, inherited or acquired deficiency of complement is associated with an increased frequency of infection. As a major effector of the complement cascade, the membrane attack complex is responsible for direct complement dependent serum bactericidal activity. Especially late complement component deficiency has a markedly increased risk of meningococcal infection and is subject to recurrent infection. We experienced a patient who had recurrent meningococcal meningitis and septicemia. The patient was 13-years old boy and he had a recurrent episode after 20 months. At second admission, we examined complement level and C7 deficiency was confirmed. He was treated without complication. We report a case of deficiency of C7 with recurrent meningococcal meningitis and septicemia.

For quarantine purpose, we selected five plant RNA viruses including Cucumber vein yellowing virus (CVYV),Cucurbit yellow stunting disorder virus (CYSDV), Potato aucuba mosaic virus (PAMV), Potato yellow dwarf virus (PYDV), and Tomato chlorosis virus (ToCV), which are not reported in Korea and cause serious economic losses to the family Cucurbitaceae or Solanaceae. To detect those viruses, we employed RT-PCR technique with specific oligonucleotide primer pairs and tested their detection efficiency for each virus. To design RT-PCR primers,coat protein was used for CVYV, CYSDV, and ToCV whereas RNA polymerase and nucleocapsid regions were used for PAMV and PYDV, respectively. The development of an RT-PCR based method proved a useful tool for rapid detection and identification of quarantine virus infections.
