Increase in Serotype 6C Pneumococcal Carriage, United Kingdom
To the Editor: Streptococcus pneumoniae is a major human pathogen. In 2007, Park et al. identifi ed a novel serotype, 6C (1), which emerged from serotype 6A. A study of children in the Netherlands who had not previously received a pneumococcal vaccine found low prevalence of this newly identifi ed serotype before the heptavalent pneumococcal conjugate vaccine Prevnar/Prevenar (PCV7) (Wyeth, Tap...
متن کاملPneumococcal carriage in United Kingdom families: estimating serotype-specific transmission parameters from longitudinal data.
Repeated observations of pneumococcal infection in 121 United Kingdom families (October 2001-July 2002) were used to explore the transmission properties of five highly prevalent pneumococcal serotypes (6A, 6B, 14, 19F, 23F). A family-based Markov model was developed, and maximum likelihood estimates were produced for model parameters. The authors found higher community acquisition rates among p...
متن کاملIncrease in the prevalence of the newly discovered pneumococcal serotype 6C in the nasopharynx after introduction of pneumococcal conjugate vaccine.
BACKGROUND Because pneumococcal serotype 6C was previously not distinguished from serotype 6A, the impact of the 7-valent pneumococcal conjugate vaccine (PCV7) on the carriage of serotype 6C is unknown. METHODS The nasopharyngeal (NP) prevalence of the 6C serotype was determined using 1326 pneumococcal isolates collected from 7 cohorts of Massachusetts children between 1994 and 2007. Initiall...
متن کاملSurveillance of pneumococcal serotype 1 carriage during an outbreak of serotype 1 invasive pneumococcal disease in central Australia 2010–2012
BACKGROUND An outbreak of serotype 1 invasive pneumococcal disease (IPD) occurred in Central Australia from October 2010 to the latter part of 2012. Surveillance of serotype 1 carriage was conducted to determine epidemiological features of asymptomatic carriage that could potentially be driving the outbreak. METHODS 130 patients and accompanying persons presenting at Alice Springs Hospital Em...
متن کاملSerotype 6C invasive pneumococcal disease in indigenous people in north Queensland.
The seven-valent pneumococcal conjugate vaccine (7vPCV) includes serotype 6B. No invasive pneumococcal disease (IPD) caused by this serotype has occurred in Indigenous people in north Queensland since 7vPCV was made freely available to Indigenous children in the latter part of 2001.3 Although 7vPCV does not include serotype 6A, the experience in the United States of America (USA) indicates that...
