我国各地区溶组织内阿米巴(又名痢疾阿米巴、痢疾变形虫)的感染率悬殊较大,高者可达30％,低者仅为0.37％;华北地区一般较华中及华南地区低。由于此种致病性阿米巴感染引起的发病例占少数,各地学者对其致病力的见解不同,如有些学者依据其滋养体及包囊的大小、形态结构结合虫株毒力。对人体及动物产生的病变以及在培养基上繁殖的情况,作为划分宗、株与致病的关系。综合文献资料,多数学者认为大宗阿米巴,它们的滋养体直径在12微米以上,包囊直径在10微米以上者为大型致病性阿米巴,命名为溶组织内阿米巴(Entamoebahistolytica);小宗阿米巴,它们的滋养体直
In our country, the infection rates of Entamoeba histolytica (also known as dysentery amoebae, amoebae dysentery) vary greatly, with the highest up to 30% and the lowest being only 0.37%. In North China, the infection rates are generally lower than those in Central China and South China low. As a result of this pathogenic amebic infection caused by a small number of cases, local scholars on their virulence of different opinions, such as some scholars according to their trophozoites and cysts size, morphological structure combined with virulent strains. The human body and animal diseases and the propagation of the medium on the situation, as a division of cases, strains and pathogenic relationship. Comprehensive literature, most scholars believe that large amebiasis, their trophozoites diameter of 12 microns or more, cysts diameter of more than 10 microns for the large pathogenic amoeba, named Entamoeba histolytica (Entamoeba histolytica) Small pieces of amoeba, their trophozoites straight
