研究了 T.spiralis、T.pseudospiralis、T.nativa 和 T.nelsoni 的核型。核型比较表明,4个物种的染色体数目均一致。对于女性样本,2n = 6;对于男性样本,2n = 5。旋毛虫个体的相对染色体长度存在差异。并不显着。着丝粒指数数据表明,T. nativa 和 T.spiralis 具有相似的着丝粒配置,但与其他 2 个物种不同。通过第一亚中着丝粒染色体对的着丝粒的配置。在 T. nativa 和 T. nelsoni 中,单价性染色体的大小为第二,并且稍微近中着丝粒;在 T.spiralis 和 T.pseudospiralis 中,它是第三条中间着丝粒染色体。
Karyolotypes of T. spiralis, T. pseudospiralis, T. nativa and T. nelsoni were studied. Comparison of the karyotypes showed that the chromosome number of all 4 spp. is 2n = 6 for female specimens with 2n = 5 for males. The differences found in the relative chromosome lengths of the individual Trichinella spp. are not significant. Centromeric index data indicate that T. nativa and T. spiralis have similar centremere dispositions and differ from the other 2 spp. by the disposition of the centromere of the 1st submetacentric chromosome pair. In T. nativa and T. nelsoni the univalent sex chromosome is the 2nd in size and is slightly submetacentric; in T. spiralis and T. pseudospiralis it is the 3rd metacentric chromosome.
