The BIOGRAM (Difco Laboratories, Detroit, Mich.) system, which is designed to calculate MICs from disk diffusion zone diameters, was compared with two commercial microdilution antimicrobial susceptibility systems. A total of 111 clinical isolates were evaluated with each test system. Six additional isolates were tested in a comparison between BIOGRAM and Sceptor (Johnston Laboratories, Inc. Tow...

OBJECTIVE To determine the resistance rate of the most commonly used antimicrobial agents amongst Helicobacter pylori isolates. METHODS The agar disk diffusion method (Kirby Bauer) was utilized to determine the susceptibility of 223 H. pylori strains isolated before treatment. Isolates were tested against metronidazole (5 micrograms), clarithromycin (15 micrograms), amoxycillin (10 micrograms...

background and objective: methicillin resistance in staphylococcus aureus is an increasingly important clinical problem. a chromosomal gene, meca, mediates resistance to penicillinase-resistant penicillins such as methicillin and oxacillin in staphylococcus aureus. we evaluated the validity of disk diffusion test by using oxacillin, methicillin and cefoxitin disks with consideration of the pres...

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 university...

herbs have been used for its medicinal properties from several thousand years ago. herbs, essences and extracts, possess a variety level of biological activities and antimicrobial activities of a large number of them have been proved. eucalyptus is one of these plants which the anti-virus effects of its extract has long been used to treat influenza and colds in most parts of the world. the aim ...

background :    unfortunately, antibiotic resistance has become an increasingly critical problem in many countries like iran. since there are very few published data on antibiotics resistance in alborz province, the aim of this study was to survey the pattern of antimicrobial resistance and prevalence detection of tem-type beta-lactamases among clinical isolates of escherichia coli using univer...

The objective of the present study was to determine the frequency of Staphylococcus aureus nasal carriage among dialysis and kidney transplant patients, to identify the antimicrobial resistance profile of these strains and to verify their genetic profiles with the RW3A primer. The study included 159 individuals, comprising 111 dialysis and 48 kidney transplant patients. Of the 48 transplant pat...
