The nucleotide sequence of the 16S rRNA gene of Mycoplasma bovis has been determined. Comparisons with other 16S rRNA sequences of mycoplasmas showed that Mycoplasma agalactiae is phylogenetically the closest relative. In total, only eight nucleotides differed between the M. bovis and M. agalactiae 16S rRNA sequences. The phylogenetic position of M. bovis with respect to other mycoplasmas was determined by sequence comparisons and from features in the secondary structure of 16S rRNA.
已测定了牛支原体16S rRNA基因的核苷酸序列。与其他支原体的16S rRNA序列进行比较表明，无乳支原体在系统发育上是最接近的亲缘种。牛支原体和无乳支原体的16S rRNA序列总共只有8个核苷酸不同。通过序列比较和16S rRNA二级结构的特征确定了牛支原体相对于其他支原体的系统发育位置。
