Background and Objective: Methicillin-resistant Staphylococcus aureus (MRSA) is one of the most common microorganisms that is recovered from clinical bacterial isolates. Clinical and Laboratory Standards Institute (CLSI) recommends usage of cefoxitin when using the disk diffusion method to determine resistance against methicillin for S. aureus. The aim of our study was to evaluate the efficacy ...
Background and Objective: Since the preparation of antibacterial materials in dentistry is very noticeable, therefore, we tried to evaluate this effect on Streptococcus mutans by addition of silica nanoparticles to LCGI (light curing glass ionomer). Materials and Methods: In this in vitro study, we had five LCGI experimental groups that contained 0, 0.2, 0.5, 1, and 2% (w/w) of silica nanopa...
Antibiotic resistance of Intensive Care Unit (ICU) born aerobic gram-negative bacteria was evaluated during a six months period at a teaching hospital in Tehran, and determination of the validity of the results obtained from disc diffusion tests, using discs manufactured in Iran. Disc susceptibility tests using Iranian and standard discs (diffusion discs available in international markets) were...
background and objectives: staphylococcus aureus is one of the main causatives of bovine mastitis. resistance of some strains to methicillin, can complicate the treatment of its infections. on the other hand, enterotoxin production is also im- portant. therefore, the aim of our study was to investigate the methicillin resistance and enterotoxin production in s. aureus isolates caused bovine m...
sagebrush genus (artemisia scoparia) is the one of the most important genus of asteraceae family. it has numerous values because of medicine properties. sagebrush genus has numerous application in traditional medicine from ancient times. in this research, the isolation and identification of essential oil and antibacterial activity of artemisia scoparia have been studied. samples were collected ...
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...
Fastidious organisms present problems in antimicrobial susceptibility testing related to particular cultural requirements or slow growth. Methods for commonly isolated fastidious organisms, including haemolytic streptococci, Neisseria spp. and Haemophilus spp., are included in the description of the standardized disc diffusion method. However, some further information is given here for Haemophi...

Sagebrush genus has numerous application in traditional medicine from ancient times. In this research, the isolation and identification of essential oil and antibacterial activity of Artemisia scoparia have been studied. Samples were collected ...
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...
conclusions: with respect to the obtained results and regarding to the daily increase of the resistant microbial strains to the commercial antibiotics, it can be concluded that these extracts can be proper candidates of antibacterial substance against pathogenic bacterial species especially s. aureus, e. coli, k. pneumoniae and s. epidermidis. results: the extract of c. fistula was effective ag...
