Evaluation of serotype-specific pneumococcal IgG measurement using two different polysaccharides from ATCC and SSI Diagnostica.

Streptococcus pneumoniae (pneumococcus) is a major cause of morbidity and mortality especially in infants and elderly people. Pneumococcus capsular polysaccharide has been characterised and more than 90 different serotypes have been identified. Serotype-specific antibodies against the capsular polysaccharide are produced during infection.

Test of a novel Streptococcus pneumoniae serotype 6C type specific polyclonal antiserum (factor antiserum 6d) and characterisation of serotype 6C isolates in Denmark.

Background: In 2007, Park et al. identified a novel serotype among Streptococcus pneumoniae serogroup 6 which they named serotype 6C. The aim of this study was to evaluate with the Neufeld test a novel S.

Purification and structure characterization of the active component in the pneumococcal 22F polysaccharide capsule used for adsorption in pneumococcal enzyme-linked immunosorbent assays.

Protection against pneumococcal disease is thought to be mediated primarily by antibodies that are opsonic [Musher DM, Chapman AJ, Goree A, Jonsson S, Briles D, Baughn RE. Natural and vaccine-related immunity to Streptococcus pneumoniae. J Infect Dis 1986;154(2):245-56].

Integron-mediated ESBL resistance in rare serotypes of Escherichia coli causing infections in an elderly population of Israel.

Objectives: To identify and characterize the aetiology of an outbreak of extra-intestinal multidrug-resistant Escherichia coli infections in elderly patients in Israel.

Methods: Extended-spectrum beta-lactamase (ESBL)-producing clinical isolates of E. coli from extra-intestinal sources were tested for susceptibility to non-beta-lactam drugs, and their serotypes were determined.
