We evaluated the Xpert MRSA/SA SSTI real-time PCR assay (Cepheid, Sunnyvale, CA) directly on perioperative bone and joint samples. The sensitivity and specificity for detection of methicillin-susceptible Staphylococcus aureus (MSSA), methicillin-resistant Staphylococcus aureus (MRSA), and methicillin-resistant coagulase-negative Staphylococcus were, respectively, 100% and 98.3%, 100% and 100%, ...

The emergence of bacterial antibiotic resistance is a growing problem, yet the variables that influence the rate of emergence of resistance are not well understood. In a microfluidic device designed to mimic naturally occurring bacterial niches, resistance of Escherichia coli to the antibiotic ciprofloxacin developed within 10 hours. Resistance emerged with as few as 100 bacteria in the initial...

A total of 100 chicken samples (breast and thigh), 50 fresh carcass samples, 25 local frozen samples and 25 imported frozen samples were analyzed and the antibiotic residues were estimated by using Four Plate Test (FPT). Results revealed that 90 %, 88 % and 72 % of fresh, local frozen and imported frozen samples were positive for residues of different antibiotics, respectively. Samples were pos...

In this research, for the first time in Iran, Deferoxamine test for differential diagnosis between Staph. epidermidis and Staph. hominis of other gram­positive cocci is introduced. Besides, the comparative results of the susceptibility rates of Staph. aureus (220 Spp.) and Enterococci ( 110 Spp.) to a new glycopeptide antibiotic (SK&Fl04662) and other 12 antibiotics are presented by Disk-Agar D...

Material and Methods: Children as dental patients, a study The records of 100 children between age 2-10 years visiting a pediatric dental clinic for various pulpal and periapical conditions were evaluated. A total of 364 procedures (pulp therapies such as pulpotomy and pulpectomy, and extractions) were carried out in the children for different pulpal and periapical pathologies (irreversible pul...

The activity of 6-[d(-)-alpha-carboxy-3-thienylacetamido] penicillanic acid, BRL2288, was determined against Pseudomonas aeruginosa and various gram-negative bacilli. The majority of Pseudomonas strains (89%) were inhibited by 100 mug of the antibiotic per ml. BRL2288 is twofold more active than carbenicillin against Pseudomonas at 100 mug/ml or less. Among Enterobacteriaceae tested, 87% Entero...

Empirical antibiotic therapy in seriously ill patients requires careful selection of antibiotics. This study was planned to determine the pattern of bacterial infections and culture sensitivities in patients admitted to a medical intensive care unit (ICU). Patients with positive bacterial cultures from specimens of blood, urine, endo-tracheal tube, suction catheter, and tracheal aspirates were ...

conclusions based on our findings, p. aerugionsa is a major causative agent of wound infections and amikacin could be considered as a more effective antibiotic for treatment of the burned patients. background nowadays, the treatment of burned patients is difficult because of the high frequency of infection with antibiotic resistance bacteria. objectives this study was conducted to evaluate the ...

This study compared the utilization and cost of antibacterial agents in surgical units of 2 government hospitals in Palestine. The consumption and cost of drugs was estimated in the units over a 1-month period in 2010 using the anatomical therapeutic chemical classification and defined daily doses (DDD) per 100 bed-days. The total consumption of antibacterial agents was 414.1 DDD and 591.5 DDD ...

Staphylococcus epidermidis isolates containing subpopulations resistant to 100 microgram of methicillin per ml were found on the chests of only 3 of 80 (4%) patients before cardiac surgery, whereas these highly resistant staphylococci were isolated from the chest wounds of 43 of 80 (54%) patients 5 days postoperatively. The percentage of patients colonized with methicillin-resistant S. epidermi...
