In order to understand resistance pattern of Escherichia coli clinical isolates, the outer membrane permeability trend of different antibiotics was studied. The outer membrane permeability of Elores was compared with other commonly used intensive care unit (ICU) drugs being used in the treatment of various infections caused by resistant E. coli. A total of fifty three isolates collected under EASE programme from North Indian hospitals, fifteen extended spectrum β-lactamases (ESBL) positive clinical isolates of E. coli were included in the study. Michaelis constants (Km) and maximal rates of substrate hydrolysis (Vmax) were determined from Lineweaver-Burk plot. Permeability coefficient was determined using the method described by Zimmermann and Rosslet. Elores demonstrated the lowest Vmax/Km ratio further indicating its lower affinity (high Km 209.9 ± 17.4 μM) towards &b.. View More»
