Abstract Background Detection of ceftazidime/avibactam (CAZ/AVI) antibacterial activity is absolutely vital with the rapid growth of carbapenem resistant Enterobacteriaceae (CRE). But now, there is no available automated antimicrobial susceptibility testing card for CAZ/AVI, so Kirby-Bauer has become an economical and practical method for detecting CAZ/AVI antibacterial activity against Enterobacteriaceae. Result In this study, antimicrobial susceptibility testing of CAZ/AVI against 386 Enterobacteriaceae (188 Klebsiella pneumoniae, 122 Escherichia coli, 76 Enterobacter cloacae) isolated from clinical patients was performed by broth microdilution. Of the 386 strains, 54 extended spectrum β lactamases negative (ESBL(−)), 104 extended spectrum β lactamases positive (ESBL(+)), 228 CRE. 287 isolates were susceptible to CAZ/AVI and 99 isolates were resistant to CAZ/AVI. At the same time, to obtain optimal content avibactam (AVI) disk containing ceftazidime (30 μg), inhibition zone diameter of four kinds of ceftazidime (30 μg) disk containing different AVI content (0 μg, 10 μg, 25 μg, 50 μg) were tested by Kirby-Bauer method. The microdilution broth method interpretation was used as the standard to estimate susceptible or resistance and then coherence analysis was carried out between Kirby-Bauer and broth microdilution. The result shows the inhibition zone diameter of 30 μg/50 μg disk, susceptible isolates: 20.5 mm–31.5 mm, resistance isolates: 8.25 mm–21.5 mm. The inhibition zone diameter of 30 μg/25 μg disk, susceptible isolates: 19.7 mm–31.3 mm, resistance isolates: 6.5 mm–19.2 mm. The inhibition zone diameter of 30 μg/10 μg disk, susceptible isolates: 19.5 mm–31 mm, resistance isolates: 6.5 mm–11 mm. The inhibition zone diameter of ceftazidime (30 μg), susceptible isolates: 6.5 mm–27.5 mm, resistance isolates 6.5 mm. Conclusion Our results show that 30 μg/50 μg, 30 μg/25 μg, 30 μg/10 μg CAZ/AVI disk have significant statistical differences to determinate CAZ/AVI antibacterial activity, but for 30 μg/50 μg disk, there has a cross section between susceptible isolates (minimum 20.5 mm) and resistance isolates (maximum 21.5 mm). For 30 μg/25 μg disk, it is hard to distinguish the difference between susceptible isolates (minimum 19.7 mm) and resistance isolates (maximum 19.2 mm), so 30 μg/10 μg CAZ/AVI disk is more conducive to determinate antibacterial activity.

Introduction: Many medicinal plants produce antioxidants and antimicrobial properties which protect the host from cellular oxidation reactions and other pathogens highlighting the importance of search for natural antimicrobial drugs. Method : The antibacterial activity of 25, 50 and 100 mg/ml aqueous extract of garlic and onion on S.aureus, S. Typhi,P. aeruginosa and E. coli isolates were carried out using agar well diffusion method. The antibacterial activity of the aqueous plant extract were measured by zones of inhibition and the antibiotic sensitivity test of the bacteria isolates was done using the disc diffusion method. Results: Inhibition zone diameter of 18 mm, 19 mm, 21 mm and 27 mm were observed for E.coli, P.aeruginosa, S.aureus, and S.Typhi respectively using 100 mg/ml of garlic while for onion, 11.5 mm, 12 mm, 12 mm and 13 mm inhibition zone diameter were observed for the same bacteria isolates respectively. It was observed that the increase in concentration of garlic is needed for better antibacterial activity while increasing concentration does not have a significant effect on the antibacterial activity of onion. The results of the antibiotic tests showed that most of the tested organisms exhibited multiple drug resistance to the conventional antibiotics including cotrimoxazole, chloramphenicol, amoxillin, streptomycin and septrin. Conclusion: Garlic extract showed greater antimicrobial potential compared with onion extract and the widely used antibiotics. Thus, aqueous garlic extract may be more effective in the treatment of bacterial infections in order to overcomethe problem of multidrug resistance of bacterial pathogens.
