Serotype 19A Streptococcus pneumoniae strains are now more frequent in French children than before the introduction of a seven-valent conjugate vaccine (PCV7). By applying multilocus sequence typing to 144 serotype 19A isolates collected before and after beginning PCV7 vaccination, we detected clonal expansion of the preexisting penicillin-intermediate sequence type 276.
19A 血清型肺炎链球菌菌株在法国儿童中现比七价结合疫苗(PCV7)引入之前更为常见。通过对PCV7疫苗接种前后收集的144株19A血清型分离株进行多位点序列分型,我们检测到先前存在的青霉素中介序列型276的克隆性扩增。
