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 ...
discussion our results indicated that agar screening was superior to oxacillin disk agar diffusion. a comparison between the antibiotic sensitivity patterns of the mrcns and the methicillin-susceptible coagulase-negative staphylococci (mscns) showed that the mrcns were predominantly multiple-drug resistant isolates as the simultaneous resistance rate to 4 or more antibiotics in the mrcns and ms...
background and objectives: urinary tract infections (utis) are of the most common bacterial diseases worldwide. we investigate the antibiotic susceptibility patterns of escherichia coli (e. coli) strains isolated from pediatric patients with community acquired urinary tract infection (uti) to find a clinical guidance for choosing a right empirical antibiotic in these patients. materials and met...
BACKGROUND Coagulase-negative staphylococci (CNS) are a common cause of nosocomial infections. In recent years, an increase in the incidence of methicillin-resistant coagulase-negative staphylococci (MRCNS) has led to the severity of the disease. OBJECTIVES The aim of this study was to isolate and identify MRCNS strains by oxacillin disk agar diffusion, oxacillin agar screening, and polymeras...
Introduction & Objective: UTI is one of the most common bacterial infections and Ecoli is known as an important cause of UTIs. Since bacterial resistances of antibiotics are increasing, reliable methods of antimicrobial resistance detection are of paramount importance in treatment and management of UTIs. The objective of the present study is to compare and to evaluate the performance of disk ...
Antimicrobial susceptibility testing for Helicobacter pylori is increasingly important due to resistance to the most used antimicrobials agents. Only agar dilution method is approved by CLSI, but it is difficult to perform routinely. We evaluated the reliability of E-test and disk diffusion comparing to agar dilution method on Helicobacter pylori antimicrobial susceptibility testing. Susceptibi...
BACKGROUND AND PURPOSE A simplified antifungal disk diffusion test using Mueller-Hinton agar containing 2% glucose and methylene blue 5 microg/mL (GM-MH, Clinical and Laboratory Standards Institute [CLSI] M44-A) has proved to correlate well with the standard reference test. A new azole, voriconazole, has recently been approved for clinical therapy in Taiwan. This study investigated the reliabil...
Different antimicrobial susceptibility testing methods to detect low-level vancomycin resistance in enterococci were evaluated in a Scandinavian multicenter study (n=28). A phenotypically and genotypically well-characterized diverse collection of Enterococcus faecalis (n=12) and Enterococcus faecium (n=18) strains with and without nonsusceptibility to vancomycin was examined blindly in Danish (...
مقدمه: درسالهای اخیر شاهد گزارشات زیادی از پیدایش ایزوله های انتروباکتر مقاوم به آنتی بیوتیکهای بتالاکتام هستیم. بتالاکتامازهای وسیع الطیف (esbls) از مهمترین مکانیسمهای مقاومت به این داروها محسوب میشوند. هدف از این مطالعه تعیین شیوع esbls در ایزوله های مقاوم، به روش double disk approximation test (ddat) وتعیین فراوانی ژن blaper-1 است. مواد و روش ها: 100ایزوله انتروباکتر از بیماران بستری در بی...
