【摘要】 １９９０～１９９５年广西壮族自治区报告急性弛缓性麻痹（ＡＦＰ）病例１１８９例，采集粪便标本９９４例，分离出病毒２２４株，阳性率２２．５４％。其中脊髓灰质炎（脊灰）病毒１５３株，分离率１５．３９％；非脊灰肠道病毒（ＮＰＥＶ）７１株，分离率７．１４％。１５３株脊灰病毒中，Ⅰ型８８株（５７．５２％），Ⅱ型４３株（２８．１０％），Ⅲ型１４株（９．１５％），混合型８株（５．２３％）。经国家脊灰实验室鉴定：１９９９０～ｌ９９２年分离到１７株Ⅰ型野毒株，ｌ株Ⅰ＋Ⅱ型野毒株；ｌ９９３～ｌ９９５年分离３１株脊灰病毒均为疫苗株。结果表明Ⅰ型是我区主要的流行毒株。更多还原

【Abstract】 n l990-1995 in Guangxi Zhudrngzu Autonomous Region,there were l,l84 AFP cases reportedand 994 fecal specimens(including two stool specimens)collected,The virus isolation rdte was 22.54%(224/9M).The isolation of polioviruses were 153 stnlins,the isolation rate was 1 5.39%.Thenon-polio enterovirs(NPEV)isolated ware 7l strains,the isolation rate was 7.14%The results of vi-nis typing showat that among l53 poliovirus strdins,88 were polio Ⅰ( 57.52%), 43 werepolio Ⅱ(28.10%),14 were typeⅢ(9.1 5%)and 8 were nllXed types(5.23%).Throughidentification by National Poliomyelitis Laboratory,it proved that l7 polio Ⅰwild type strains andl polioⅠ+ Ⅲ wild type strain were isolated in l990-l992,but all that isolated in l993-l995were polio vaccine s trains,It clearly showed that poliovirus type had been the dominantprevelent virus type in Guangxi Zhuangzu Autonomous Region.更多还原
