statement of problem: surface disinfection is an important aspect of infection control in dentistry. a new generation of quaternary ammonium components (qacs) is gaining popularity as high-level disinfectants. two types of qac sprays, uniseptaquick and solarsept, are being widely used by iranian dentists. purpose: the aim of this study was to evaluate the clinical efficiency of unisepta quick a...

Background: Pseudomonas aeruginosa, as an etiological agent, has a prominent infection role in serious burned patients. Burned patients usually treated with antiseptic ointments such as silver sulfadiazine (SSD). This study evaluated the effectiveness of 1% SSD and different concentrations of silver nitrate solution (SNS) on resistant isolates of P. aeruginosa. Methods: Three groups of P. aerug...

the objective of this study was to determine the phenotypic characteristics of kpc-producing pseudomonas aeruginosa and acinetobacter baumannii isolates. a case report study was performed at a tertiary burn care centre in tehran,  iran.  nine  isolates  of pseudomonas  aeruginosa  and  acinetobacter baumannii from a hospitalized case were isolated. the identity of isolates was confirmed and the...

PURPOSE To report the treatment of therapy-resistant Pseudomonas aeruginosa keratitis with topical piperacillin/tazobactam. METHODS Retrospective report of 3 cases. RESULTS Three patients with P. aeruginosa keratitis were unresponsive to various antimicrobials. Resolution of all 3 cases of keratitis occurred upon commencement of topical piperacillin/tazobactam. CONCLUSION Therapy-resistan...

Resistance to extended-spectrum cephalosporins complicates treatment of Pseudomonas aeruginosa infections. To elucidate risk factors for cefepime-resistant P. aeruginosa and determine its association with patient death, we conducted a case-control study in Philadelphia, Pennsylvania. Among 2,529 patients hospitalized during 2001-2006, a total of 213 (8.4%) had cefepime-resistant P. aeruginosa i...

BACKGROUND The contaminated contact lens provides Pseudomonas aeruginosa an ideal site for attachment and biofilm production. Continuous contact of the eye to the biofilm-infested lens can lead to serious ocular diseases, such as keratitis (corneal ulcers). The biofilms also prevent effective penetration of the antibiotics, which increase the chances of antibiotic resistance. METHODS For this...

OBJECTIVES To assess the prevalence, levels of antimicrobial susceptibility and resistance mechanisms of Pseudomonas. METHODS A total of 445 clinical isolates and 200 environmental isolates were collected from three hospitals in Minia, Egypt. The MICs of different antibiotics were determined using the agar dilution method. The isolates were tested for beta-lactamase production and for the pre...

conclusions p. aeruginosa and s. marcescens can be good candidates for the detoxification of cr (vi) in soltan abad river. results the results indicated that pseudomonas aeruginosa and serratia marcescens were the most resistant bacteria with mics of 200 and 150 mg/l, respectively. both bacteria completely reduced 25 and 50 mg/l of cr (vi) in 36 hours and 48 hours, respectively. the growth rate...

L-656,575 (OCP-9-176) is a novel oxacephem superior to ceftazidime in in vitro activity against clinical isolates of Enterobacter species, methicillin-susceptible Staphylococcus aureus and Staphylococcus epidermidis, and multiply-resistant Pseudomonas aeruginosa. Our results suggest that L-656,575 has a high affinity for penicillin binding proteins of Pseudomonas and may bind preferentially to ...
