سودوموناس آئروژینوزا یک پاتوژن فرصت طلب است که از عوامل مرسوم عفونت های بیمارستانی میان کودکان و بزرگسالان می باشد این باکتری معمولاً نسبت به آنتی بیوتیک های معمول با مکانیسم های ذاتی یا اکتسابی مقاوم هستند در بیشتر موارد کارباپنم ها مثل ایمی پنم انتخاب نهایی در درمان است بنابراین سویه های مقاوم به کارباپنم در شکست درمانی بسیار مهم هستند. هر تغییر در پورینoprd باعث تغییر در نفوذپذیری غشا می شود ...

Eighteen Enterobacteriaceae and Pseudomonas aeruginosa strains, 16 of them with well-defined beta-lactam resistance mechanisms, were sent to 52 Spanish microbiology laboratories. Interpretative categories for 8 extended-spectrum beta-lactams were collected. Participating laboratories used their own routine susceptibility testing procedures (88% automatic systems, 10% disk diffusion, and 2% agar...

All (236) Pseudomonas aeruginosa isolates resistant to imipenem and/or meropenem collected during a multicenter (127-hospital) study in Spain were analyzed. Carbapenem-resistant isolates were found to be more frequently resistant to all beta-lactams and non-beta-lactam antibiotics than carbapenem-susceptible isolates (P < 0.001), and up to 46% of the carbapenem-resistant isolates met the criter...

We investigated the mechanisms of resistance to carbapenems, aminoglycosides, glycylcyclines, tetracyclines, and quinolones in 90 multiresistant clinical strains of Acinetobacter baumannii isolated from two genetically unrelated A. baumannii clones: clone PFGE-ROC-1 (53 strains producing the OXA-58 β-lactamase enzyme and 18 strains with the OXA-24 β-lactamase) and clone PFGE-HUI-1 (19 strains s...

BACKGROUND Pain tolerance is subject to considerable inter-individual variation, which may be influenced by a number of genetic and non-genetic factors. The mu, delta and kappa opioid receptors play a role in pain perception and are thought to mediate different pain modalities. The aim of this study was to explore associations between pain thresholds and gender and genetic variants in the three...

Carbapenem-resistant bacteria represent a significant treatment challenge due to the lack of active antimicrobials available. MK-7655 is a novel β-lactamase inhibitor under clinical development. We investigated the combined killing activity of imipenem and MK-7655 against four imipenem-resistant bacterial strains, using a mathematical model previously evaluated in our laboratory. Time-kill stud...

OBJECTIVES Although Pseudomonas aeruginosa from cystic fibrosis patients are well known for their antibiotic resistance, isolates that are highly susceptible to multiple drug classes have also been encountered. In this study, hypersusceptible P. aeruginosa isolates were analysed for changes in intrinsic resistance mechanisms to explain the observed phenotype. METHODS P. aeruginosa strains PA3...
