本文首次报道三平正并殖吸虫染色体核型由11对染色体组成,其中1对较大,为中部着丝点染色体(m);另4对中等大,为亚端部着丝点染色体(st);余6对较小,其中2对为中部着丝点染色体(m),4对为亚中部着丝点染色体(sm)。 三平正并殖吸虫第1对和第6对染色体在虫种鉴别上似有一定意义,值得进一步研究。 In this paper, we report for the first time that the karyotype of the Paragonimus serogroup is composed of 11 pairs of chromosomes, of which 1 is relatively large, which is the centromere chromosome (m); the other 4 pairs are moderately large and the subfamily centromere (st) ; The remaining 6 pairs were smaller, of which 2 were centromeric chromosomes (m) and 4 were sub-centromeric chromosomes (sm). Paragonimus three Ping Paragonim 1 and 6 pairs of chromosomes in the identification of species may have some significance worthy of further study.
