Treponeme outer cell envelope: solubilization and reaggregation.

Abstract

Exposure of the avirulent Kazan 5 treponeme to low concentrations of sodium dodecyl sulfate (1.4 mm) results in the solubilization of the outer envelope. Maximal reaggregation of the outer envelope preparation requires cations, and cation concentration affects both the yield and structure of the aggregates. The reaggregated outer envelope preparation can be resolubilized with the chelating agent, ethylenediaminetetraacetic acid, or with sodium dodecyl sulfate.

Rapid identification of Streptococcus pneumoniae by PCR amplification of ribosomal DNA spacer region.

Streptococcus pneumoniae is one of the important human pathogens in clinical microbiology. A polymerase chain reaction assay was designed to detect and identify S. pneumoniae through amplification of the ribosomal DNA spacer regions between the pneumococcal 16S-23S ribosomal RNA genes. Thirty-two Streptococcus and non-Streptococcus strains were tested to verify the specificity of the assay, and only S. pneumoniae strains gave a positive reaction. This method is a powerful technique for the rapid identification of S. pneumoniae.
