肺炎球菌是引起儿童急性化脓性中耳炎重要病原菌之一。近年来,由于经常发现耐药菌株,国外很重视研究致病肺炎球菌的血清型及免疫预防的方法。1977年美国已正式批准制备14价肺炎球菌荚膜多糖疫苗,接种易感人群,预防肺炎球菌感染。1983年又增至23价,取得了一定的社会效果。按丹麦或美国分类,迄今已发现的肺炎球菌血清型有80多个,而引起疾病的常见血清型一般约20个;且常因地区、时间、年龄和病种的不同而发生变化。因此,为了有效地控制引起疾病的肺炎球菌血清型,提高防
Pneumococcal is caused by acute suppurative otitis media in children one of the important pathogens. In recent years, due to the frequent discovery of drug-resistant strains, foreign countries attach great importance to studying the pathogenic pneumococcal serotype and immunoprophylaxis. In 1977 the United States has officially approved the preparation of 14-valent pneumococcal capsular polysaccharide vaccine, vaccination of susceptible populations, prevention of pneumococcal infection. In 1983 it was increased to 23 and achieved some social effects. According to the Danish or American classification, there have been over 80 pneumococcal serotypes so far found, while the common serotypes causing the disease are generally about 20; and often vary by region, time, age and disease type. Therefore, in order to effectively control the pneumococcal serotype that causes the disease, anti-inflammatory drugs are added
