Trends in serotype incidence and susceptibility (1997 to 2008) of Spanish Streptococcus pneumoniae pleural isolates (n = 831) were explored. Penicillin (oral) nonsusceptibility rates and the incidence of 7-valent pneumococcal conjugate vaccine (PCV-7) serotypes showed decreasing trends (R(2) ≥ 0.600; P ≤ 0.002). The incidence of serotypes 1 and 19A showed increasing trends (R(2) ≥ 0.759; P < 0.001), with no trends for serotype 3. Serotypes 19A, 1, and 3 represented 85% of pediatric isolates in 2008. In serotype 19A, the penicillin nonsusceptibility rate was 82.4% in 2008, associated with amoxicillin and cefotaxime nonsusceptibility in 21.4% of isolates. Inclusion of these serotypes in new vaccines offers the broadest coverage.
研究了西班牙肺炎链球菌胸膜分离株(n = 831)血清型发生率和敏感性(1997 年至 2008 年)的变化趋势。青霉素(口服)不敏感率和 7 价肺炎球菌结合疫苗(PCV-7)血清型的发生率呈下降趋势(R²≥0.600;P≤0.002)。血清型 1 和 19A 的发生率呈上升趋势(R²≥0.759;P<0.001),而血清型 3 则没有趋势。2008 年,血清型 19A、1 和 3 占儿科分离株的 85%。在血清型 19A 中,2008 年青霉素不敏感率为 82.4%,其中 21.4%的分离株对阿莫西林和头孢噻肟不敏感。将这些血清型纳入新疫苗可提供最广泛的保护。
