PG - 126292 LID - S0723-2020(21)00115-6 [pii] LID - 10.1016/j.syapm.2021.126292 [doi] AB - Since 2006, a Mycoplasma species unidentifiable to the species level has been regularly isolated from the semen and prepuce of apparently healthy bulls, and occasionally from cattle displaying inflammatory disease of the genital tract. Seven of these Mycoplasma isolates were subjected to a comprehensive taxonomic study. The strains investigated grew well in modified Hayflick's medium and colonies on agar exhibited typical fried egg morphology and produced 'film and spots'. Transmission electron microscopy revealed a cell morphology characteristic of mycoplasmas with spherically shaped cells bounded by a bi-layered cell membrane. The strains studied neither produced acid from sugar carbon sources nor did hydrolyse arginine or urea, and genome annotation indicated that organic acids (pyruvate, lactate) are used as energy sources. Phylogenetic analyses of 16S rRNA gene sequences, the 16S-23S intergenic spacer region, and partial rpoB gene and protein sequences placed the strains within the Mycoplasma (M.) bovis cluster of the Hominis group with M. primatum, M. agalactiae, and M. bovis being their closest relatives. Genomic information including whole-genome similarity metrics (ANIb, ANIm, TETRA, dDDH, AAI) and phylogenomics, proteomic features revealed by matrix-assisted laser desorption ionization time of flight (MALDI-ToF) mass spectrometry as well as serological reactions and polar lipid profiling strongly indicated that the strains examined were representatives of a hitherto unclassified species of genus Mycoplasma, for which the name Mycoplasma tauri sp. nov. with type strain Zaradi2(T) (=ATCC BAA-1891(T) = DSM 22451(T)) is proposed.
