摘要: 应用Sumner的BSG法,对卫氏并殖吸虫两个型的染色体C带带型进行了分析,结果表明两型间存在着差别。三倍体型卫氏并殖吸虫有两套染色体,其中一套在C带带型上与二倍体型相一致,另一套染色体则具有不同的带型,此差别突出表现在2、3、5、6和7号染色体上。表明两型间染色体结构不完全相同;卫氏并殖吸虫三倍体型可能是二倍体型的异源多倍体。

Abstract: Diploid and triploid types of Paragonimus westermani had similar cbromosomal karyotypes, however, they differed in chromosome c-band patterns. Two of three homologues of the triploid resembled those of the diploid in c-banding pattern, while the remaining chromosomes showed a different pattern. Heterogcneity in homologues was observed especially in chromosome Nos. 2, 3, 5, 6 and 7 (Fig. l, 2). In the diploid chromosome specimen, mitotic and meiosic phases were observed, while only the mitotic; phase was found in the triploid chromosome.
