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...

objective: nowadays notable increase in acquired resistance of candida species to antifungal drugs and necessity of using agents with antifungal properties is unavoidable. in some plants due to presence of components such as polyphenols have antimicrobial properties. in this study antifungal effects of essential oils of thymus vulgaris, petroselinum crispum, cuminum cyminum and bunium persicum ...

the infections risk related to pathogenic germs increases at the present time considering the increased resistance which certain microbes acquire, whose usual antibiotics are ineffective to treat the infectious disease. the aim of this study was to determine antimicrobial effect of the aqueous and ethanolic extracts of lavandula stoechas l. and rosmarinus officinalis l. on listeria monocytogene...

The antimicrobial and cytotoxic effects of sodium hypochlorite (NaOCl) and sodium dichloroisocyanurate (NaDCC) were evaluated and compared in vitro. The minimal inhibitory concentration and minimal bactericidal concentration of NaOCl and NaDCC were tested for Streptococcus sobrinus, Streptococcus salivarius, Enterococcus faecalis, and Streptococcus mutans. The cytotoxic effect was assessed by u...

The effect of combinations of gentamicin with trimethoprim or sulfamethoxazole-trimethoprim against clinical isolates of Escherichia coli (11 strains) and Klebsiella pneumoniae (12 strains) was examined by using a microdilution checkerboard technique. All isolates were susceptible to each antimicrobial agent. Synergism, defined as at least a 2-log(2)-dilution lowering of the minimal inhibitory ...

We evaluated the efficacy, safety, and tolerance of cefotaxime in 35 adults (25 with pleuropulmonary infections, 7 with genitourinary tract infections, and 3 with soft tissue infections). Of these 35 patients, 18 (51.4%) were seriously or critically ill. In vitro susceptibility testing revealed that 90.4% of the pathogens isolated were susceptible to cefotaxime (minimal inhibitory concentration...

abstract       background and objective: enterococci are relatively nonvirulent bacteria that rarely cause disease. antimicrobial treatment of enterococci is often challenging due to their antibiotic resistance. this study aimed to investigate the antibacterial activity of aqueous extract of garlic against enterococcal isolates.     methods: in this descriptive study, 120 enterococcus isolates ...

conclusions totally, our results showed nanosilver caused an increase of at least nine-fold in inhibitory effect of fluconazole. materials and methods we studied effect of fluconazole, nanosilver, and their combination on 20 fluconazole-resistant c. albicans from two centers and one standard sample (atcc10261) by minimal inhibitory concentration (mic) method. background opportunistic fungi caus...

Streptomyces lunalinharesii strain 235 produces an antimicrobial substance that is active against sulfate reducing bacteria, the major bacterial group responsible for biofilm formation and biocorrosion in petroleum reservoirs. The use of this antimicrobial substance for sulfate reducing bacteria control is therefore a promising alternative to chemical biocides. In this study the antimicrobial s...

Penicillin-resistant Neisseria gonorrhoeae from 405 patients were studied by determination of penicillin minimal inhibitory concentrations an penicillinase production. Eighteen percent were identified as penicillin-producing N. gonorrhoeae and the mean minimal inhibitory concentration, for all except penicillin-producing strains, was 0.805 micrograms/ml.
