abstract       background and objective: due to the continuous increase of multidrug-resistant acinetobacter baumannii strains around the world, decision making for an effective treatment of infections caused by this organism depends on the results of antimicrobial susceptibility tests. in this study, the validity of disk diffusion and e-test methods was assessed by their comparison with the re...

Background: The increasing demand for natural preservatives results in their extended usefulness. The objective of the present study was to investigate the physicochemical and antioxidative characteristics of Rhus coriaria L. (sumac) fruit and comparison of its antioxidative and antibacterial activity with Zataria multiflora Essential Oil (ZEO) as native Iranian natural additives. Methods: Ant...

introduction: the escherichia coli o157:h7 is considered an agent responsible for the outbreak of hemorrhagic colitis and the hemolytic uremic syndrome (hus). this serotype belongs to the subspecies of enterohemorrhagic e. coli (ehec). the ehec o157:h7 produces intimin, shiga toxins (stx1, stx2 or both). this study investigates the effect of thyme alcoholic extract on the growth and production ...

This study compares the inhibitory effect of ceftizoxime with that of penicillin G, chloramphenicol, cephalothin, cephalexin and cefzoline on Klebsiella pneumoniae, Proteus mirabilis, pseudomonas ruginosa, staphylococcus aureus, staphylococcus epidermidis, staphylococcus saprophyticus and Escherichia coli. The in vitro inhibitory effect of ceftizoxime on P. mirabilis, P. Aeruginosa, S.prophytic...

Antimicrobial activity of the roots of Eranthemum roseum (Vahl) R.Br. (Dasmuli), were tested against different bacteria (including Escherichia coli, Staphylococcus aureus, Bacillus subtilis, Shigella sonnei, Klebsiella pneumoniae, Salmonella typhi, Proteus vulgaris, Pseudomonas aeruginosa) and fungi (such as Candida albicans and Aspergillus niger) by cup plate diffusion method. Minimal Inhibito...
