“…This might be explained to some extent by the ability of minocycline to thwart AdeABC efflux, and a lower rate of minocycline-resistance development in A. baumannii (Lomovskaya et al 2014). Clinical responses to Minocin IV used as a monotherapy or in combination for the treatment of MDR A. baumannii infections appear encouraging (Goff et al 2014;Ritchie and Garavaglia-Wilson 2014;Falagas et al 2015), but this therapy will likely be a stop-gap as the spread of RPPs should increase minocycline resistance.
