Morphologic Changes

The synergistic activity of antimicrobial combinants against aerobic and facultative microorganisms has been well documented. in comparison, few studies have been performed using obligate anaerobic isolates and antimicrobial combinants. For this study clinical strains of Bacteroides fragilis(BF) were selected to investigate both single/combinant drug activity and cellular morphologic changes when BF is exposed to Imipenem (I), Piperacillin (P), Cefpimizole (C), Imipenem/Piperacillin (I+P), and Imipenem/Cefpimizole (I+C).

Here we describe the synthesis and electrochemical testing of a heteroleptic bis(tridentate) ruthenium(II) complex [Ru<sup>II</sup>(LR)(L)]<sup>0</sup> (LR =2,6-bis(1-(2-octyldodecan)benzimidazol-2-yl)pyridine, L = 2,6-bis(benzimidazolate)pyridine). It is a neutral complex which undergoes a quasireversible oxidation and reduction at relatively low potential. The newly synthetized compound was used for studies of ion-transfer at the three-phase junction because of the sensitivity of this method to cation expulsion. The [Ru<sup>II</sup>(LR)(L)]<sup>0</sup> shows exceptional stability during cycling and is sufficiently lipophilic even after oxidation to persist in the organic phase also using very hydrophilic anions such as Cl<sup>−</sup>. Given its low redox potential and strong lipophilicity this compound will be of interest as an electron donor in liquid-liquid electrochemistry.
