Introduction: Multi-drug resistant (MDR) P. aeruginosa is constantly increasing and causing severe issues in combatting widely spread health problems. The aim of this study was to assess colistin susceptibility in MDR P. aeruginosa isolates obtained from different infection sites. Methods: Ninety clinical isolates of P. aeruginosa were collected from different hospitals of the Tabriz Univer...
Currently, no agar-based susceptibility testing method has been standardized for testing dermatophytes. We describe a newly developed agar-based method employing disk diffusion assay to test the susceptibility of 47 isolates of dermatophytes against 8 antifungals. Our results show that the method is reproducible, is simple, and could be used to determine the antifungal susceptibility of dermato...
conclusions the results of this study suggest that e. hebecarpa extracts can be used to inhibit the planktonic and biofilm forms of these selected bacteria. objectives in an effort to combat these industrial and medical bacterial biofilm problems, our study aims to determine the antimicrobial effect of euphorbia hebecarpa. materials and methods the inhibition efficiency of alcoholic extracts on...
pinus eldarica medw. (iranian pine) is native to transcaucasian region and has been vastly planted in iran, afghanistan, and pakistan. various parts of this plant have been widely used in traditional medicine for the treatment of various diseases including infectious conditions (e.g. infectious wounds). in this study we aimed to investigate the antibacterial activity of p. eldarica bark extract...
background: essential oils and their major constituents are useful sources of antimicrobial compounds. there are a few reports on the decontamination and antimicrobial activity of essential oils towards shigella spp. m aterials and methods: in this study, the antimicrobial and decontamination potentials of essential oils at different concentrations, belonging to plants such as thymus vulgaris, ...
ba ckground: legionella pneumophila is a dangerous pathogenic bacterium can cause serious infectious diseases especially in hospitalized immuno-compromised patients. this bacterium is shown to be resistant against different antibiotics. resistance against a wide range of antibiotics is usually mediated by efflux pump in bacteria. efflux pumps are proteinaceous transporters localized in the cy...
A total of 907 consecutive isolates of members of the family Enterobacteriaceae recovered during a 20-week period were tested for production of extended-spectrum beta-lactamases (ESBLs) by the double-disk (DD) potentiation method. Of 84 DD-positive isolates, 83 (9.2%) produced ESBLs based on isoelectric focusing. SHV-derived ESBLs and several TEM-derived ESBLs were present in nine species, incl...
background and objectives:increased antibiotic resistance as a result of using antimicrobial drugs and also their various adverse effects has caused that in recent years, investigation of medicinal plants beconsidered for discovering new medicinal resources against bacterial infections. this study was performed with the objective of determining the antimicrobial activity of aqueous and ethanoli...
Susceptibilities of 124 strains of Streptococcus pneumoniae to erythromycin and clindamycin were determined by the National Committee for the Clinical Laboratory Standards (NCCLS) broth microdilution method, with incubation for 20 to 24 h in ambient air and with modifications of this method by incubation for up to 48 h in air and CO2. Strains were also tested by agar dilution, E-test, and disk ...
results the mean of the inhibition zone diameter around the discs of green tea extract in all concentrations was significantly less than 1% sodium hypochlorite (p < 0.001). the antimicrobial effect increased in higher concentrations of extracts of green tea (p < 0.001). conclusions although the antimicrobial effect increases in higher concentrations of extracts of green tea, 1% sodium hypochlor...
