  • Bordetella pertussis is pathogenic bacteria causing pertussis, a infectious respiratory disease for the infants. The incidence rate of pertussis was significantly decreased after introduction of vaccine. However, increased pertussis cases are recently reported in several countries with high vaccine coverage. One of the inferred reasons is genotype or serotype variation between circulating strains and vaccine strains. Therefore, it is required to confirm the variation status of the isolates by genotype or serotype analysis and the possibility of pertussis outbreak in Korea should be estimated. For this, the serotype variations of the isolates from $1999\sim2006$ were investigated in agglutinogen and fimbriae. As the result, the most frequent serotype in the isolated strains was agglutinogen 1 and fimbriae 2 serotypes. Moreover, serotype transition from vaccine serotypes to non-vaccine serotypes was observed. Especially, the transition pattern of agglutinogen serotype was directed to increase a different type (agg 1) from the vaccine type (agg 1,2). However, in case of fimbriae, the same type (fim 2) with vaccine strain was increased. These results were also observed in other countries with increasing incidence of pertussis. For more predictable results to know increasing possibility of pertussis incidence in Korea, the studies on genetic variations of antigenic determinant genes and prevalence of antibody titer in normal population should be performed in the further.

  • 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.
