四种牛首科吸虫染色体的观察

OBSERVATIONS ON CHROMOSOMES OF FOUR BUCEPHALIDS SPECIES (DIGENEA)

  • 摘要: 作者对四种牛首科吸虫的染色体进行了观察和相对长度的测量.结果显示,假扇盘吸虫的染色体组型为n=4m+1st+2t=6,吴氏似牛首吸虫的染色体组型为n=4m+2sm+1t=7,湖北似牛首吸虫的染色体组型为n=7m=7,范尼道佛吸虫的染色体组型为n=6m+1sm=7.其中,假扇盘吸虫、吴氏似牛首吸虫和湖北似牛首吸虫的染色体数目和组型为首次报道.

     

    Abstract: Chromosomes of four bucephalid species, Pseudorhipidocotyle elopichthys Long et Lee,1964; Bucephalopsis Wui Long et Lee, 1964, B. hupehensis Wang et Pan,1964 and Dollfustrema vaneyi (Tseng, 1930) Eckmann, 1934 were observed. Their karyotypes are as follows : n = 4m + 1st + 2t = 6, n = 4m + 2sm + 1t = 7, n = 7m = 7 and n = 6m + 1sm = 7, respectively. Chromosomes and karyotypes of P. elopichthys, B.wui and B. hupehensis were reported for the first time.
