Typing of pneumococci by using 12 pooled antisera.
A new simplified chessboard system for typing of Streptococcus pneumoniae is described. It is intended for typing or grouping of 90 to 95% of the pneumococcal strains most commonly isolated from blood or cerebrospinal fluid and is based on 12 pooled diagnostic antisera, each reacting with 7 to 11 single types, together covering the 23 different vaccine-related types as well as 25 other cross-re...
متن کاملSonochemically Assisted Synthesis of ZnO Nanoparticles: A Novel Direct Method
Nanocrystalline ZnO particles were prepared by a novel sonochemical route from zinc acetate and sodium hydroxide without any requirement of calcination steps at high temperature and without surfactants. Variations in several parameters and their effects on the structural (crystal size and morphology) properties of nanoparticles were investigated. Characterizations were carried out by X-Ray ...

Molecular typing of pneumococci for investigation of linked cases of invasive pneumococcal disease.
In winter 2007-2008, an outbreak of pediatric pneumonia caused by serotype 5 pneumococci was identified in a northeast London suburb. Variable number of tandem repeat analyses clustered these pneumococci from the other serotype 5 pneumococci in the United Kingdom, highlighting the importance of this discriminative typing method in supporting epidemiological investigations.
