  • Bordetella pertussis는 유아의 호흡기감염질환인 백일해의 원인균으로 배신도입에 의해 발생률이 크게 낮아졌다. 그러나 최근에 일부 백신접종률이 높은 국가에서 증가된 백일해 발생건수가 보고되고 있으며, 그 추정 원인 중에 하나는 백신주와 유행주 사이의 유전형 흑은 혈청형 변이 이다. 따라서 분리주에 대한 변이 현황을 유전형 혹은 혈청형 분석을 통하여 확인하는 것이 필요하고 국내에서 백일해 발병증가에 대한 가능성을 추정해야 한다. 이에 본 연구에서는 $1999\sim2006$년 사이에 분리된 국내 백일해 분리균주의 변이 양상을 agglutinogen과 fimbriae에 대한 혈청형 조사를 통해 확인하였다. 그 결과 agg 1과 fim 2가 국내 분리주에서 가장 많이 발견되는 혈청형이었고, 두 항원 모두 시대에 따른 혈청형 변이 현상이 확인되었으며, 특히 agglutinogen의 경우는 백신균주(agg 1,2)와는 다른 유형(agg 1)이 증가되는 유형으로 나타났다. 그러나 fimbriae의 경우는 백신균주(fim 2)와 동일한 유형이 증가되어 차이를 나타내었다. 이러한 결과는 백일해 발병증가가 나타나는 국가들에서도 확인되는 현상으로 국내에서의 백일해 발병증가에 대한 보다 정확한 예측을 위해서는 항원결정기 유전자에 대한 변이정도 및 정상인에서의 항체가 분포양상 등에 대한 연구가 필요할 것으로 사료된다.

  • Antigenicity of Rhodotrula rubra isolated from pulmonary tissue of pulmonary tuberculosis patients was studied by means of agglutination reaction with R. rubra whole cell antiserum. And the serological reactivity of crude polyfac charide from R. frubra, Candida albicans, Candida tropicalis, Candida, glabrata, and Saccharomyces cerevisiae ATCC 26603 with antiserum to R. rubra whole cell was studied by means of immunodiffusion test. R. rubra showed stationary phase after 48h when it was cultured in GYEP broth. While agglutinogen titer was 1:64 at lag phase, agglutinogen titer was 1 :256 after 20h. After growth of R. rubra on different 11 media, nutritional environment showed similar agglu-tination reartivity. The agglutinogen titer of C. albicans, C. tropicalis, C. giabrata, which were isolated from patient's expectoration, to R. rubra antiserum by means of agglutination reaction were 1:16, respectively. But, Sacch. cervisiae ATCC26603 was negative. Those results were lower than that of R. rubra agglutinogen titer 1:256. As a result of immu-nodiffusion test with crude polysaccharide extracted from cell wall of R. rubra, C. albicans, C. tropicalis, C. glabrata, Sacch. cervisiae ATCC26603, precipitin line was found only with R. rubra, of which antibody titer was 8.

  • Acellular pertussis vaccine has been used widely in Korea since 1984. However, because many of the former generations were not inoculated with pertussis vaccine, they may infect infants with pertussis. With this background, we investigated the prevalence of pertussis antibodies in all age groups. Enzyme-linked immunosorbent assay (ELISA) to assess IgG antibodies to pertussis toxin (PT) and filamentous hemagglutinin (FHA) and bacterial agglutination (BA) to assess antibodies to agglutinogen were compared on 842 serum samples which were donated from 11 hospitals in Seoul area. In comparison with age groups under 20 years, antibodies of adults against PT and FHA were maintained. But antibodies against agglutinogen showed no pattern in all age groups. Antibodies to PT were correlated with antibodies to FHA. There was no significant difference in antibody levels between male and female (p<0.05).

  • An attempt was carried out to purify the cell components of Bordetella bronchiseptica by the mild procedures. From the supernatant of sonic treated colls, the K-agglutinogen, hemagglutinogen and skin necrotizing factor were separated by a successive use of DEAE-cellulose column chromatography and ammonium sulfate precipitation. The specific activity of purified K-agglutinogen was demonstrated by a gel-diffusion test and was also found to be free from other biologically active substances of B. bronchiseptica: namely hemagglutinin, skin-necrotizing factor and O-antigen.

  • It was well known that B. pertussis cells possess protective antigen, histamine sensitizing factor, heatstable and labile toxin, hemagglutinin, agglutinogen and the others. Previous reports involving above antigenic properties of B. pertussis have been carried out for several years. However, leucocyte promoting property was not yet investigated. In this report, the results of studies on the leucocytosis, particulary the lymphocytosis, produced in mice by injecting pertussis vaccine were presented. Especially leucocyte promoting property and histamine sensitizing property of B. pertussis vaccine treated at various temperatures were compared. The relationship between the leucocyte promoting property and histamine sensitizing property was investigated. Results were as follows. 1. Although leucocytosis was significantly rised in both 0.5ml injection and 0.1ml injection of pertussis vaccine than in control, at the higher dose (0.5ml injection) an elevation in white cell count was more significant. The leucocyte responce to pertussis vaccine was greater following 0.5 ml injection than following 0.1ml injection. 2. Lymphocytosis was significantly rised in both 0.5ml injection and 0.1ml injection of pertussis vaccine than in control. At higher dose (0.5ml injection), an elevation in lymphocyte count was more significant. 3. Order of elevation in differential leucocyte counts was lymphocyte, polymorphonuclear leucocyte and monocyte. 4. The leucocyte response to pertussis vaccine was 2 fold greater following intravenous injection than following subcutaneous injection. 5. Decrease leucocyte promoting activity and histamine sensitizing activity resulted from exposure to temperature above $56^{\circ}C$. Histamine sensitizing activity of pertussis vaccine treated at various temperatures paralleled leucocyte promoting activity.
