Antimicrobial susceptibility patterns of Ureaplasma species and Mycoplasma hominis in pregnant women Redelinghuys, Mathys J.; Ehlers, Marthie Magdaleen; Dreyer, Andries W.; Lombaard, H.A.D.T. (Hennie); Kock, Marleen M. (BioMed Central, 2014-03)BACKGROUND : Genital mycoplasmas colonise up to 80% of sexually mature women and may invade the amniotic cavity during pregnancy and cause complications. Tetracyclines and fluoroquinolones are contraindicated in pregnancy ...
