Four commercially available rapid agglutination tests for the identification of Staphylococcus aureus were compared with the tube coagulase test for the identification of 300 methicillin-resistant isolates of staphylococci. Isolates tested included 207 methicillin-resistant S. aureus and 93 coagulase-negative staphylococci, collected from five medical centers. Strain variability was documented ...

Effect of different solvents; dimethyl-sulfoxide (DMSO), dimethyl formamide (DMF), methanol, tween 80 and acetone on morphology, cytology and reproduction of Aspergillus flavus, A. parasiticus, A. fumigatus and A. niger was assayed for standardization of a suitable organic solvent for test/antimicrobial compound in antimicrobial assays. Comparison of antimicrobial sensitivity methods was also m...

introduction:   the resistance of pathogenic bacteria to antibiotics has now raised an issue worldwide. as the e.coli is the most common cause of urinary tract and nosocomial infections, the present study was designed to determine the antimicrobial susceptibility of e.coli in the urine culture of patients admitted to imam reza hospital in kermanshah. material and methods: for this descriptive s...

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...

Two methods for determining the sensitivity of Haemophilus ducreyi to antimicrobial agents were compared; an agar dilution method and the Etest. The MICs of seven antimicrobial agents; penicillin V, ampicillin, trimethoprim, tetracycline, chloramphenicol, erythromycin and ciprofloxacin were determined for 20 strains of H. ducreyi. The MICs determined with the Etest and with the agar dilution me...

PURPOSE We studied the results of urine cultures and antimicrobial sensitivity tests according to the voiding method used by spinal cord injury (SCI) patients over a recent 10-year period. MATERIALS AND METHODS We retrospectively analyzed 1,236 urine samples and their antimicrobial sensitivity tests for 112 patients who had used only one voiding method between January 2000 and December 2009. ...

background: diagnosis of food allergy is difficult in children. food allergies are diagnosed using several methods that include medical histories, clinical examinations, skin prick and serum-specific immunoglobulin e (ige) tests, radio-allergosorbent test (rast), food challenge, and supervised elimination diets. in this study we evaluated allergies to cow's milk, egg, peanut, and fish in c...

BACKGROUND O'Neill's recent Review on Antimicrobial Resistance expressed the view that by 2020 high-income countries should make it mandatory to support antimicrobial prescribing with rapid diagnostic evidence whenever possible. METHODS Routine microbiology diagnosis of 95 respiratory specimens from patients with severe infection were compared with those generated by the Unyvero P55 test, whi...

background. this study evaluated the antimicrobial activity of tetraacetylethylenediamine-sodium perborate (taed-sp) in comparison to 2.5% and 5% sodium hypochlorite (naocl) against enterococcus faecalis. methods. a standard suspension of e. faecalis was inoculated on 60 plates containing mueller-hinton agar culture medium. four sterile disks of beckman filtration paper were placed on each plat...

This study analyzes the National Residue Program (NRP) of the Food Safety and Inspection Service (FSIS), United States Department of Agriculture (USDA), data for the years 1983-1998 to determine the effectiveness of all three microbiological screen tests that were developed and used by the FSIS to control antimicrobial residues in food animals. The Swab Test On Premises (STOP) was the first scr...
