The incidence of Haemophilus influenzae and Streptococcus pneumoniae in children with acute respiratory infection (ARI) under 5 years was carried out by throat swab culture, blood culture, body fluid or tissue culture in 688 patients from a community, 744 patients from a teaching hospital in Bangkok, 766 normal children from the community and 303 children from a hospital well baby clinic. H. influenzae was found in the throats of 15-20% of patients and in the throats of 4-6% of normal children (p less than 0.001 for both hospital and community patients). Only 12/332 strains (3.6%) of H. influenzae were type b. The rest of H. influenzae were non type b. The most common biotype of H. influenzae non type b was biotype II. S. pneumoniae was found in hospital patients in highly significant numbers compared to the controls (12% vs 4%). No significant difference was observed in strains from the community patients.
对来自某社区的688例5岁以下急性呼吸道感染（ARI）儿童、曼谷一家教学医院的744例患儿、该社区的766例正常儿童以及一家医院健康婴儿诊所的303例儿童，通过咽拭子培养、血培养、体液或组织培养检测流感嗜血杆菌和肺炎链球菌的发病率。在15%-20%的患者咽部发现了流感嗜血杆菌，在4%-6%的正常儿童咽部也发现了该菌（医院和社区患者的p值均小于0.001）。在332株流感嗜血杆菌中，只有12株（3.6%）为b型。其余流感嗜血杆菌为非b型。非b型流感嗜血杆菌最常见的生物型是生物型II。与对照组相比，在医院患者中发现的肺炎链球菌数量显著更多（12% 对4%）。在社区患者的菌株中未观察到显著差异。
