زمینه و هدف: تولید بتالاکتا مازهای وسیعالطیف توسط ایزولههای انتروباکتریاسه به عنوان یک مکانیسم مهم مقاومت در مقابل آنتیبیوتیکهای بتالاکتام محسوب میشود. این مقاومت اکنون یکی از معضلات اصلی برای درمان عفونتهای میکروبی میباشد. هدف از این مطالعه بررسی فراوانی بتالاکتامازهای وسیعالطیف در ایزولههای انتروباکتریاسه و تعیین الگوی مقاومت آنتیبیوتیکی این ایزولهها میباشد. <st...
a simple, rapid and low-cost scanner spectroscopy method for the glucose determination by utilizing glucose oxidase and cdte/tga quantum dots as chromoionophore has been described. the detection was based on the combination of the glucose enzymatic reaction and the quenching effect of h2o2 on the cdte quantum dots (qds) photoluminescence.in this study glucose was determined by utilizing glucose...
Background & Aims: The production of extended-spectrum-β-lactamases (ESBLs) is the main mechanism of resistance to β-lactam antibiotics. The outbreak of isolates simultaneously possessing several resistance mechanisms to β-lactam antibiotics caused a decrease in sensitivity of the confirmatory tests for ESBL. The aim of this study was the evaluation of the β-lactamase disk test method in the de...

The effectiveness of 13 antimicrobial agents against 51 clinical isolates of Nocardia was determined with use of agar dilutions and disk diffusion method. Amikacin inhibited less than 90% of isolates and, like the other aminoglycosides, showed good correlation between minimal inhibitory concentrations and sizes of zones of inhibition around the disks. Both sulfisoxazole and trimethoprim-sulfame...
conclusions the β-lactamase disk test is appropriately sensitive to detect esbls in mdr isolates of e. coli. background most urinary tract infections (utis) are caused by escherichia coli (e. coli) species. due to infections outbreaks of e. coli strains with multiple mechanisms of resistance to β-lactam antibiotics, the sensitivity of confirmatory tests to detect the extended spectrum β-lactama...
Introduction: Mupirocin, an inhibitor of bacterial isoleucyl-tRNA synthetase, has used to treat staphylococcal skin infections as well as to eliminate nasal carriage of Staphylococcus aureus. Mupirocin resistant Staphylococcus aureus strains are seen worldwide but there is no report from Iran. In the present study, by using phenotyping methods (disk diffusion and E-test) in combination with P...
The activity of sulfamethoxazole (SMX), trimethoprim (TMP), and the combination of the two was determined against a variety of anaerobic bacteria. Brucella agar was somewhat inhibitory for SMX and TMP but activity was good and equivalent in Diagnostic Sensitivity Test Agar (Oxoid) and Mueller-Hinton agar and the latter was selected for use in these studies. Agar dilution susceptibility tests sh...
We report on a computation of congruent numbers, which subject to the Birch and Swinnerton-Dyer conjecture is an accurate list up to 10. The computation involves multiplying large theta series as per Tunnell (1983). The first method, which we describe in some detail, uses a multimodular disk based technique for multiplying polynomials out-of-core which minimises expensive disk access by keeping...
