| Abstract: |
| 本文复习了我国37年(1949~1985)来自各地区报道的155 122株痢疾杆菌。分析菌群分布表明,平均仍以B亚群所占比例最高(80.5%),但八十年代以来有所下降(68.1%)。B亚群中流行亚群是2a与lb;但1a与2b比例有增加趋势。西北和中南地区A亚群比例近来明显增高,提示有关地区环境污染严重,饮水卫生差,亦可能与细菌毒力变异有关,防治中需特别注意。B:D亚群比值以华东地区最低,该比值同经济文化发达水平有一定关系。 |

| The authors isolated 155 122 Strains of Shigella from different areas in China and reviewed for thirth-seven years. Analysis was shown that the the persentage of Subgroup B relative in the all isolations was highest (80.5%), beffore 1980's, but decreasal in 1980's (68.5%). Both 2a and 1b within Snbgroups B were epidemic subtypes, but there were trend of rise of both la and 2b recently、 Obvious increase in proportion of subgroups A in North-West and South-Centre areas of China recently suggested that the environmental contamination and poor sant tation of drinking water in the above areas mighbe the reasons to explain the above phenomenon also might be associated with virulence variation othe bacteria. The Health Authority needs to pay attention to its prevention and therapy. Ratio of B to D subgroups in East China wao lowest, it appeared haat there were Some relationship between this phenomenon and cnlture economic level in an area. |
