Chromosome characteristics of Trichobilharzia franki Müller et Kimming, 1994, causing swimmer's itch in the Western Germany, were described and compared with the karyotype of the sympatric species Trichobilharzia szidali Neuhaus, 1952. Karyotypes of both species are very similar: diploid sets consist of seven pairs of autosome chromosomes and one pair of sex chromosomes (2n = 16, n = 5m + 2sm + Zsm/Wst), the sex determining mechanism is ZZ in males and ZW in females and gross morphology of autosome pairs does not differ markedly. The only clear discriminative feature lies in the size and shape of sex chromosomes.
描述了1994年在德国西部引起游泳者瘙痒的弗兰克毛毕吸虫(Trichobilharzia franki Müller et Kimming)的染色体特征,并将其与同域物种1952年的斯氏毛毕吸虫(Trichobilharzia szidali Neuhaus)的核型进行了比较。两种物种的核型非常相似:二倍体组由七对常染色体和一对性染色体组成(2n = 16,n = 5m + 2sm + Zsm/Wst),性别决定机制为雄性为ZZ,雌性为ZW,常染色体对的总体形态没有明显差异。唯一明显的鉴别特征在于性染色体的大小和形状。
