Does dystocia during labor pose a risk factor for another non-progressive labor during the subsequent delivery?
A previous CS due to a NPL is an independent risk factor for another NPL in the subsequent pregnancy and for recurrent cesarean delivery.
These results strongly suggest that overexpression of IM proteins, by using a non-PTS carbohydrate as the sole carbon source, or by artificially introducing a high number of copies of an unrelated IM protein, competes with the antibiotic efflux systems, thereby decreasing the efflux-mediated resistance to different antimicrobial compounds. This sort of competition arises because of the limited available space in the bacterial IM, or by an unknown mechanism.
