BACKGROUND/PURPOSE In industrialized countries, Clostridium difficile is the major cause of nosocomial diarrhea. This study involved a broad overview of baseline epidemiology for C. difficile in Taiwan. MATERIALS AND METHODS Point prevalence was estimated from a prospective survey conducted in the respiratory care wards of six hospitals in central Taiwan.(More)
Shigella sonnei replaced Shigella flexneri to become the predominant species for shigellosis in 2001 to 2003 in central Taiwan. A total of 425 S. sonnei isolates collected from 1996 to 2004 were available for characterization by pulsed-field gel electrophoresis (PFGE), inter-IS1 spacer typing (IST), and antimicrobial susceptibility testing. The results(More)
Shigella sonnei contains numerous IS1 elements. The existence of polymorphisms in the length of the inter-IS1 spacer is a basis for the development of a PCR-based method for the subtyping of S. sonnei strains. The usefulness of inter-IS1 spacer typing (IST) was evaluated and compared with that of pulsed-field gel electrophoresis (PFGE) by characterization(More)
The number of scarlet fever occurrences reported between 2000 and 2006 fluctuated considerably in central Taiwan and throughout the nation. Isolates of Streptococcus pyogenes were collected from scarlet fever patients in central Taiwan and were characterized by emm sequencing and a standardized pulsed-field gel electrophoresis (PFGE) method. National weekly(More)
Polymerase chain reaction (PCR) ribotyping is one of the globally accepted techniques for defining epidemic clones of Clostridium difficile and tracing virulence-related strains. However, the ambiguous data generated by this technique makes it difficult to compare data attained from different laboratories; therefore, a portable technique that could(More)
