abstract background and aim: oral infections and dental caries are considered as two serious public health problems, which inflict a costly burden on health care services worldwide, especially in the developing countries. the aim of this study was to evaluate the antibacterial activity of iranian licorice aqueous root extract on lactobacillus acidophilus in comparison with chlorhexidine. materi...
مقدمه: آنزیم های بتالاکتاماز tem، ctx-m، shv و amp-c از آنزیم هایی هستند که بر روی عناصر قابل انتقال واقع شده اند،esbl ها بتالاکتامازهای هیدرولیز کننده پنی سیلین ها، سفالوسپورینهای وسیع الطیف و آزترئونام می باشند. آنزیم amp-c بر روی کروموزوم نیز واقع شده است. هدف از این بررسی تعیین فراوانی اشریشیاکلی های تولیدکننده esbl وارزیابی مولکولی بتالاکتامازهای tem، ctx-m، shv و amp-c توسط pcr و بررسی ژن...
background and objectives: urinary tract infections (utis) are of the most common bacterial diseases worldwide. we investigate the antibiotic susceptibility patterns of escherichia coli (e. coli) strains isolated from pediatric patients with community acquired urinary tract infection (uti) to find a clinical guidance for choosing a right empirical antibiotic in these patients. materials and met...
discussion our results indicated that agar screening was superior to oxacillin disk agar diffusion. a comparison between the antibiotic sensitivity patterns of the mrcns and the methicillin-susceptible coagulase-negative staphylococci (mscns) showed that the mrcns were predominantly multiple-drug resistant isolates as the simultaneous resistance rate to 4 or more antibiotics in the mrcns and ms...
Introduction & Objective: UTI is one of the most common bacterial infections and Ecoli is known as an important cause of UTIs. Since bacterial resistances of antibiotics are increasing, reliable methods of antimicrobial resistance detection are of paramount importance in treatment and management of UTIs. The objective of the present study is to compare and to evaluate the performance of disk ...
Introduction: S. aureus, the second most common cause of nosocomial infections, is regarded as an important factor in the severe infections of the community. Methicillin-resistant strains of this bacterium involve a major pathogen which can cause disease and mortality in Iran and the world. Its treatment seems to be difficult due to the prevalence of resistance to most commonly-used antibiotics...
abstract background: the disk diffusion method for identification of yeasts species was performed based on different but distinct susceptibilities of yeasts spp. to chemicals: janus green, ethidium bromide, 2,3,5-triphenyltetrazolium chloride, brilliant green, cycloheximide and rhodamine 6g. methods: atotal of 568 iranian soldiers went under study for isolation and identification of yeast speci...
Antimicrobial susceptibility testing for Helicobacter pylori is increasingly important due to resistance to the most used antimicrobials agents. Only agar dilution method is approved by CLSI, but it is difficult to perform routinely. We evaluated the reliability of E-test and disk diffusion comparing to agar dilution method on Helicobacter pylori antimicrobial susceptibility testing. Susceptibi...
Disk diffusion test is the usual applicable method for assessing the antimicrobial susceptibility pattern in most institutions and hospitals. The aim of this study was to determine the reliability of resistant-reported results of disk diffusion test for 6 routinely used antibiotics against Gram-positive microorganisms of nosocomial origin, using E-test method. Over a 1-year period, clinical spe...
Ticarcillin and clavulanic acid in combination were tested against 40 Pseudomonas aeruginosa isolates resistant to ticarcillin by disk diffusion. A total of 21 isolates (53%) were susceptible to ticarcillin-clavulanate by disk diffusion, under currently recommended criteria for ticarcillin susceptibility. Macro-broth dilution tests (ticarcillin plus clavulanic acid, 2 micrograms/ml) confirmed s...
