卫氏并殖吸虫二倍体型与三倍体型染色体C显带的研究

STUDY ON CHROMOSOME C-BANDING IN PARAGONIMVS WESTERMANI. COMPARISON OF THE DIPLOID AND TRIPLOID TYPES

本文以二倍体型及三倍体型卫氏并殖吸虫为材料,用BSG法对两者进行了染色体C显带的比较研究。结果表明,两者C带带型基本相同,并且具有基本一致的2、4～7号染色体的C带多态性。因而认为三倍体型卫氏并殖吸虫是二倍体型卫氏并殖吸虫的同源三倍体。本文系国内首次报告二倍体型卫氏并殖吸虫染色体的C带多态性及三倍体型卫氏并殖吸虫具有C带多态性的同源染色体的多种组合。

A comparative study was performed in detail on the c-band pattern of diploid and triploid types of Paragonimus westermani by using BSG method. The result revealed that both typas of P. westermani possessed the identical c-band pattern and c-band polymorphism. Thus the authors considered that the triploid type of P. westermani might be an autotriploid. The polymorphism of c-band pattern in diploid and the combination of homologous chromosomes with c-band polymorphism in triploid were reported for the first time (Figs.1-4).
