Tetracycline Resistance in Ureaplasma spp. and Mycoplasma hominis : Prevalence in Bordeaux, France, from 1999 to 2002 and Description of Two tet (M)-Positive Isolates of M. hominis Susceptible to Tetracyclines

Twenty-four of 128 clinical isolates of Mycoplasma hominis and 6 of 276 clinical isolates of Ureaplasma spp. from Bordeaux, France (1999 to 2002), were resistant to tetracycline and harbored the tet (M) gene. For M. hominis , we also found an increase in tetracycline resistance and two tet (M)-positive isolates that were susceptible to tetracyclines.
