Mycoplasma tauri sp. nov. isolated from the bovine genital tract.

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'.
