1982年12月～1985年5月对诊治的部份病例进行了肺炎链球菌感染情况的研究。在66例患儿69份标本中分离出69株肺炎链球菌。按丹麦分型法分布23个型(群),其中1型最多11株,其次是2型8株,5型、6群和14型各6株。在不同标本、不同年龄组、不同月份和城市与农村病儿中分离出的型(群)是有差异的。部份菌株做了药敏试验,说明目前肺炎链球菌对青霉素和红霉素的敏感性仍高,而对庆大霉素和链霉素敏感性低。 From December 1982 to May 1985, some cases of pneumococcal infection were studied. 69 strains of S. pneumoniae isolated from 69 samples of 66 children. According to the Danish typing method, 23 types (groups) were distributed, of which 11 were type 1, followed by 8 strains of type 2, 6 strains of type 5, 6 and 14 respectively. In different specimens, different age groups, different months and urban and rural sick children isolated type (group) is different. Some strains made susceptibility testing, indicating that at present the susceptibility of Streptococcus pneumoniae to penicillin and erythromycin is still high, while the low sensitivity of gentamicin and streptomycin.
