测定了梅氏新登虫的线粒体基因组全序列，并与野生贝登虫和B进行了比较。星内这个环状基因组由13，270 bp组成，包括扁形虫中发现的所有36个典型mt基因。N.梅莱尼为75.9%。ATG是最常见的起始密码子，而nad4L由GTG启动。所有的蛋白质编码基因都以TAG和TAA终止。N. melleni具有与B相同的带有TCG反密码子的trnR。seriolae，但与B不同。Hoshinai（ACG）. N. melleni与B相似。seriolae和B. hoshinai除了三个易位（trnF，trnT和trnG）。nad4L和nad4在N. melleni mt基因组，在已发表的三代虫属物种中也有报道，但在B中未发现。seriolae和B. Hoshinai，它们是非编码区。本研究为该虫种或株的鉴定及系统学研究提供了有用的分子特征。
The complete mitochondrial (mt) genome sequences of Neobenedenia melleni were determined and compared with those of Benedenia seriolae and B. hoshinai. This circular genome comprises 13,270 bp and includes all 36 typical mt genes found in flatworms. Total AT content of N. melleni is 75.9 %. ATG is the most common start codon, while nad4L is initiated by GTG. All protein-coding genes are predicted to terminate with TAG and TAA. N. melleni has the trnR with a TCG anticodon, which is the same to B. seriolae but different from B. hoshinai (ACG). The mt gene arrangement of N. melleni is similar to that of B. seriolae and B. hoshinai with the exception of three translocations (trnF, trnT and trnG). The overlapped region between nad4L and nad4 was found in the N. melleni mt genome, which was also reported for the published Gyrodactylus species, but it was not found in those of B. seriolae and B. hoshinai, which are non-coding regions instead. The present study provides useful molecular characters for species or strain identification and systematic studies of this parasite.
