Almost complete (> 96%) 16S rRNA sequences from nine ruminant mycoplasmas have been determined by solid-phase DNA sequencing. Polymorphisms were found in four of the 16S rRNA sequences, which indicated the existence of two different rRNA operons. Seven polymorphisms were found in Mycoplasma agalatiae, three were found in Mycoplasma bovis, one was found in Mycoplasma alkalescens, and one was found in Mycoplasma bovirhinis. The sequence data were used for construction of phylogenetic trees. All but one of the ruminant mycoplasmas sequenced in this work clustered in the hominis group. A close relationship was found between M. agalactiae and M. bovis, with a 99% nucleotide similarity between their 16S rRNA sequences. They were also found to be members of the Mycoplasma lipophilum cluster of the hominis group. Furthermore, the 16S rRNA comparisons showed that Mycoplasma alkalescens and Mycoplasma canadense are closely related (> 98.5%), and these species were found to cluster in the Mycoplasma hominis cluster of the hominis group. Interestingly, M. bovirhinis grouped in a new phylogenetic cluster of the hominis group. The new cluster, which was supported by bootstrap percentage values, signature nucleotide analysis, and higher-order structural elements, was named the Mycoplasma synoviae cluster. Mycoplasma bovoculi, Mycoplasma conjunctivae, and Mycoplasma ovipneumoniae clustered in the Mycoplasma neurolyticum cluster of the hominis group. Mycoplasma alvi clustered with Mycoplasma pirum in the M. pneumoniae cluster of the pneumoniae group.
