Résumé
We report the antibiofilm activity by the sponge-associated bacterium Cobetia marina upon Staphylococcus epidermidis clinical isolates obtained from central venous catheters. Antibiofilm activity/antimicrobial susceptibility correlation might predict the action of the metabolite(s) upon Staphylococcus epidermidis in the clinic, making it a possible adjuvant in therapies against biofilm-associated infections.
Résumé
1. Bradykinin, Lys-bradykinin, Met-Lys-bradykinin, des-Arg9- bradykinin and des-Arg1- bradykinin were separated by capillary zone electrophoresis in an apparatus constructed in our laboratory which utilizes a novel N2 pulsed laser-induced fluorescence detector. 2. Detection limits of 1.2 fmol for fluorescamine-derivatized bradykinin and 90 attomol for O-phthaldiadehyde-derivatized bradykinin were achieved. 3. This powerful analytical tool is described and its successful application to the measurements of bradykinin after enzymatic release from blood is documented
