background and objective: nowadays, incidence of antibiotic-resistance among pathogenic bacteria has increased due to indiscriminate use of antimicrobial drugs for treatment of diseases, especially urinary tract infections. medicinal plants are also of great importance as antibacterial agents. therefore, the aim of this study was to determine the antibacterial effect of ethanolic extract of net...
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 ...
Introduction & Objective: Urinary Tract Infection (UTI) is one of the most common infections during childhood and E-Coli is the more predominant pathogen recovered in UTI. Disk Diffusion agar test is a method of choice because it is cost effective, simple, and now routinely used for detection of antibiotic susceptibility. A rapid increase in antibiotic resistance in our region made the auth...
Background and Aim: Streptococcus sanguinis (S. sanguinis) is one of the effective bacteria in the formation of caries and periodontal diseases which are caused by dental plaque. Currently, the use of natural honey (NH) is considered as a method of reducing S. sanguinis and S. mutans in saliva, which results in reducing the dental plaque. The purpose of this study was to evaluate the effects o...
سابقه و هدف: استافیلوکوک اورئوس یکی از مهم ترین عفونت های بیمارستانی می باشد که روز به روز بر مقاومت آنتی بیوتیکی آن به گروه بتالاکتام و وانکومایسین افزوده می شود. در این مطالعه ضمن بررسی فراوانی سوش های استافیلوک اورئوس بیمارستانی مقاوم به اگزاسیلین و وانکومایسین، میزان همخوانی دو روش disk diffusion و e test در تعیین حساسیت آنتی بیوتیکی مورد بررسی قرار گرفت.روش بررسی: در این مطالعه مقطعی، 100ن...
methicillin-resistant staphylococcus aureus (mrsa) is the main cause of hospital infection emerged over the last decades. rapid detection of mrsa is important for patient care and proper usage of infection control. detection of meca genes (encoding resistance to methicillin and other similar antibiotics) and nuc genes (encoding staphylococcal thermostable nuclease) by pcr method is now consider...
We compared results of disk diffusion antifungal susceptibility testing from Candida sp. strains passaged on CHROMagar and on potato dextrose agar. The overall categorical agreements for fluconazole and voriconazole disk testing were 95% and 98% with 0% and 0.5% very major errors, respectively. Disk diffusion testing by the CLSI (formerly NCCLS) M44-A method can be performed accurately by takin...
Introduction: Staphylococcus aureus is an important cause of severe infections in hospital and community and can cause significant mortality and morbidity in patients. In this study, the susceptibility and resistance pattern of Staphylococcus aureus to common antibiotics was investigated by disk diffusion, MIC (Minimal-inhibitory concentration) determination with E-test and D-test Methods: This...
Polymyxin, Colistin, Disk diffusion, E-test, MDR, XDR Background: The widespread multidrug-resistant Gram-negative bacilli (GNB)has necessitated the evaluation of the use of older antimicrobials such as polymyxins being the last resort drugs for the treatment of life-threatening nosocomial infections. Objectives: We conducted the present study to evaluate simple disk diffusion method (the routi...
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...
