A total of 560 Legionella species were isolated from environmental water sources from public facilities from June to September 2008 throughout South Korea. The distribution of Legionella isolates was investigated according to geographical region, facility type, and sample type. The genetic diversity of 104 isolates of Legionella pneumophila serogroup 1 (sg(More)
Six hundred fifteen isolates of Streptococcus pyogenes were collected over a 6-year period from patients with pharyngitis in Korea. All isolates were characterized in terms of their antibiotic resistance, the phenotypes of erythromycin resistance, the frequencies of erm(B), erm(A), and mef(A) genes, and the emm genotype. The prevalent emm genotypes were(More)
OBJECTIVES To confirm genotype diversities of clinical isolates of Bordetella pertussis and to evaluate the risk of pertussis outbreak in Korea. METHODS Seven housekeeping genes and 10 antigenic determinant genes from clinical B. pertussis isolates were analyzed by Multilocus sequence typing (MLST). RESULTS More variant pattern was observed in antigenic(More)
The molecular typing of 202 Legionella pneumophila sg 1 isolates obtained from environmental water sources and clinical specimens from 1985 to 2007 was conducted using pulsed-field gel electrophoresis (PFGE). In this study, a total of 212 isolates were grouped into 35 different PFGE types and Type 1 was the predominant type, accounting for 28.7% in PFGE(More)
Pertussis is a representative vaccine-preventable disease. However, there have been recent outbreaks in countries where even higher vaccination against the disease. One reason is the emergence of antigenic variants, which are different to vaccine type. In Korea, reported cases have rapidly increased since 2009. Therefore, we analyzed genotype of strains(More)
OBJECTIVES The proteomic analysis of voriconazole resistant Candida glabrata strain has not yet been investigated. In this study, differentially expressed proteins of intracellular and membrane fraction from voriconazole-susceptible, susceptible dose-dependent (S-DD), resistant C. glabrata strains were compared with each other and several proteins were(More)
