Nasopharyngeal carriage of drug-resistant Streptococcus pneumoniae among children in Oman

Serotype Prevalence and Penicillin-susceptibility of Streptococcus pneumoniae in Oman

“…5,7,14 Previous study from Oman showed that 54.6% of S. pneumoniae colonizing nasopharynx of children were penicillin non-susceptible strains. 8 The most prevalent strains (6B, 19F, 23F) represent more than half (53.2%) of the resistant pneumococcal strains; an additional argument in favor of the 7-valent vaccine. The percentage of PNSP covered by the 7-valent conjugate vaccine is 62.6% while the 23-valent polysaccharide vaccine provides a coverage of 72% of the PNSP encountered in this study.…”

“…[5][6][7] Previous studies from Oman looked into the issue of penicillin resistance. 8 It is of interest to monitor the pneumococcal serotypes prevalent in the Omani community especially since the 7-valent pneumococcal conjugate vaccine has been introduced in the country recently (2008). The Objective of this study is to determine the prevalent serotypes of Streptococcus pneumoniae as well as the rate of penicillin-nonsusceptibility among pneumococci.…”
