Rme. Richards et al., INVESTIGATION OF CELL-ENVELOPE DAMAGE TO PSEUDOMONAS-AERUGINOSA AND ENTEROBACTER-CLOACAE BY DIBROMOPROPAMIDINE ISETHIONATE, Journal of pharmaceutical sciences, 82(9), 1993, pp. 975-977
Electron micrographs of log-phase Pseudomonas aeruginosa and Enterobac
ter cloacae cultured for 4 h in the presence of subinhibitory concentr
ations of dibromopropamidine isethionate indicate that this antibacter
ial agent can cause marked damage to the cell envelope structures of b
oth species. This result provides an explanation of how dibromopropami
dine can enhance the uptake and thus the activity of a second antibact
erial agent used in combination with it.
