【摘要】 １９９０～１９９５年广西报告ＡＦＰ病例１１８９例，采集粪便标本９９４例，包括双份标本共１４５２份。９９４例在标本中分离出病毒２２４株，阳性率２２．５３％，其中脊灰病毒１５３株，分离率１５．３９％，其它肠道病毒７１株，分离率７．１４％，１５３株脊灰病毒中，Ⅰ型８７株（５６．８６％），Ⅱ型４３株（２８．１０％），Ⅲ型１４株（９．１５％），混合型８株（５．２３％），经国家脊灰实验室作型内鉴别：１９９０～１９９２年分离到１６株Ｉ型野毒株，１株Ⅲ型野毒株，混合型（Ⅰ＋Ⅲ）野毒株１株。１９９３、１９９４、１９９５年分离３１株均为疫苗株。结果表明，Ⅰ型是我区主要的流行毒株更多还原

【Abstract】 cases of acute flaccid paralysis(AFP)were reported in Guangxi province during the 1990￣1995 period 994 Stool Specinens were collected from the cases 224 Virus strains were isolated from 994 specimens,with isolation rate being 22 45% Of isclated Strains,153 Straisn were poliovirus strains with isolation rate being 15 39% Among the poliovirns iolates,the numbers of poliovirns strains were:type 1,56 86%(87/153);type 2,28 10%(43/153);type 3,9 15%(14/153);and mixed type,5 23%(8/153) The numbers of poliovirus wild strains confirmed by national lahoratory of poliomyelitis research in 1990￣1992 were:type 1,16 strains;type 3,1 strain;and mixed type,1 strain However,the poliovirus strains isolated in 1993￣1995 were all vaccine strains According to the a bove-mentioned results,We consider that poliovirus type 1 strains are dominant epidemic strains in Guangxi province更多还原
