Bacitracin susceptibility was evaluated as a laboratory method to differentiate staphylococci from micrococci. A total of 317 staphylococcal isolates and 108 micrococcal isolates were each tested for susceptibility to bacitracin by a disk-diffusion method using disks of three different potencies (0.04, 2.0, and 10.0 U) and a broth dilution method to obtain MICs. When a growth inhibition zone di...

introduction main part of energy consumption in agricultural mechanization is tillage operations therefore optimization of energy consumption in tillage operation is very important. a management method for system to optimize in agriculture is simple additive weighting (saw) methodology that this method can operate according to criteria of the systems. this method states that, which system has b...

three combination methods commonly used in tourism forecasting are the simple average method, the variance-covariance method and the discounted msfe method. these methods assign the different weights that can not change at each time point to each individual forecasting model. in this study, we introduce the iowga operator combination method which can overcome the defect of previous three combin...

background: leishmaniases are a group of diseases caused by leishmania parasites .  growing of drug unresponsiveness in leishmaniasis patients necessitates the development of new drugs and accor­dingly a suitable assay is needed for evaluation of any modalities.  the aim of this study was to compare four drug assays methods, agar dilution, broth dilution, cylinder plate and disk diffusion, for ...

One-hundred-four patients with preoperative diagnoses of lumbar canal stenosis, disk herniation, or a combination of both were evaluated with intraoperative sonography with the intent of (1) describing the sonographic characteristics of herniated disks and distinguishing these from bulging anuli, epidural fat, scar tissue, and spondylolisthesis; (2) establishing criteria for adequate decompress...

BACKGROUND Staphylococcus saprophyticus is the second most frequent community-acquired causative agent of urinary tract infection (UTI). The objective of this study was to evaluate the susceptibility profile and resistance detection in Staphylococcus species. isolated from patients with UTI. MATERIALS AND METHODS The isolates were investigated using the disk diffusion method, Vitek I system, ...
