b ackground: methicillin-resistant staphylococcus aureus (mrsa) is the one of most commonly isolated organisms from clinical samples which can cause life- threatening infections. the emergence and spread of antibiotic resistance makes the treatment of these infections more complicated. in this study, we aimed to determine  the  patterns  of  antibiotic  resistance  among  mrsa  isolates  from t...

OBJECTIVES Trimethoprim/sulfamethoxazole is commonly used to treat melioidosis. Antimicrobial susceptibility testing using the disc diffusion method is commonly used in melioidosis-endemic areas, but may overestimate resistance to trimethoprim/sulfamethoxazole. PATIENTS AND METHODS We performed disc diffusion and Etest on isolates from the first positive culture for all patients presenting to...

BACKGROUND A few studies are available comparing either minimum inhibitory concentration (MIC) values with the Clinical and Laboratory Standards Institute (CLSI) disc diffusion method or MIC with the Australian Gonococcal Surveillance Program (AGSP) method. AIM This study was conducted with the aim to identify the most feasible and cost-effective method for antimicrobial susceptibility testin...

objective: sea cucumber is a traditional food and medical item and has been reported to exhibit antioxidant, antifungal, anti tumoral and antibacterial bioactivity. the objective of this study is to describe the antibacterial activity of 4 extracts of holoturia. sp (sea cucumber), collected from hengam island of persian gulf. materials and methods: methanol, hexane, aqueous and chloroform extr...

In the present study, we have encountered about 100% sensitivity to Ciprofloxacin by disc diffusion method but Nalidixic acid resistance was about 89%. Interestingly, 80 out of 93 isolates of Salmonella typhi (86.02%) and 37 out of 38 isolates of Salmonella paratyphi A (97.36%) were Nalidixic acid resistant; MIC for Ciprofloxacin being more than 1 μg/ml. This implies that Nalidixic acid resista...

background and objectives: methicillin-resistant staphylococcus aureus (mrsa) is a well-known pathogen with a worldwide distribution. given the increasing rate of mrsa infections, implementing of reliable, accurate and rapid testing for diagnosis of mrsa is necessary. the aim of this study was to compare four diagnostic methods for detection of mrsa isolates. materials and methods: from decembe...

UNLABELLED Cefoxitin is a potent inducer of the mecA regulatory system. It is being recommended for detection of methicillin resistance in Staphylococcus aureus (MRSA) when using disk diffusion testing. The aim of our study was to evaluate the efficacy of cefoxitin disc diffusion test to characterize MRSA and compare it with oxacillin agar screening and detection of mecA gene by PCR. MATERIAL...
