The E test was evaluated in comparison with reference agar methods (National Committee for Clinical Laboratory Standards) for the susceptibility testing of 248 Pseudomonas aeruginosa isolates from bladder-catheterized patients against nine antibiotics. The E-test MICs correlated well with those determined by the agar dilution and disk diffusion reference methods (88 and 92.5% within 1 log2 dilu...
Burkholderia pseudomallei, the causative agent of melioidosis was found in a small cluster of cases in Tejuçuoca, Ceará, Brazil. Tests were carried out to determine its phenotypic characteristics: colony morphology on Ashdown agar and MacConkey agar, biochemical profile in conventional biochemical tests and API 20NE, arabinose assimilation and susceptibility testing by disk diffusion, comparing...
abstract aims: bovine mastitis continues to be the most costly disease to the dairy farmers. it dominates in iran as one of the most prevalent diseases in dairy cattle among the dairy farms. mastitis treatment with antibiotics leads to the development of antibiotic resistant strains and consumer health problem. this study was performed for the first time to analyze in vitro effects of hydro-alc...
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...
The susceptibilities of 225 isolates of the Bacteroides fragilis group to six antibiotics were determined by a new disk diffusion test in Wilkins-Chalgren agar and by the standard agar dilution method. For disk diffusion, the bacteria were directly suspended in saline and immediately swabbed onto 15-cm agar plates. Disks of cefoxitin (30 micrograms), chloramphenicol (30 micrograms), clindamycin...
three extracts of pulicaria dysenterica were examined for antibacterial activity using the agar disk-diffusion method against six bacterial strains. some of these extracts were found to be active against some bacterial strains. the methanolic extract exhibited a superior level of antibacterial activity. all of the extracts were active against vibrio chlorea.
BACKGROUND AND OBJECTIVES Antibacterial susceptibility testing of clinical bacterial isolates through disk diffusion method plays a major role in antibacterial treatment. One of the main factors affecting the result of these tests is the type, structure and quality of the disks. The main objective of this study was to compare the agreement of antibiotic disks originated from three companies on ...
