During 2005, 66 carbapenem-resistant isolates of Acinetobacter baumannii were collected from seven tertiary-care hospitals participating in a nationwide surveillance network in Colombia. The isolates were multidrug resistant and produced the carbapenemases OXA-23 and OXA-51. Forty-five belonged to four clones while 21 were unique pulsotypes. One clone was present in two hospitals within one cit...
Twenty-two consecutive carbapenem-resistant enterobacterial isolates were recovered from patients hospitalized between January and April 2013 in different units at a university hospital in Istanbul, Turkey. These were Klebsiella pneumoniae isolates producing the carbapenemases OXA-48, NDM-1, and KPC-2, Enterobacter cloacae isolates producing NDM-1, and Escherichia coli isolates producing OXA-48...
In the title compound, C19H15N3O2·H2O, the oxa-diazole ring and the quinoline unit are almost coplanar, making a dihedral angle of 7.66 (8)°. The dihedral angle between the benzene ring and the quinoline system is 25.95 (8)° while that between the benzene and the oxa-diazole rings is 18.88 (9)°. The water mol-ecule is hydrogen bonded to an oxa-diazole N atom and to the quinoline N atom. In the ...
background and objectives: carbapenem resistant a. baumannii is an emerging cause of nosocomial infections. the aims of this study were identification of the most prevalent of carbapenem resistant genes, molecular typing and antimicrobial evaluation of a.baumannii in intensive care units. materials and methods: two hundred and six a. baumannii were isolated from tracheal tube discharge of hospi...
سابقه و هدف: اسینتوباکتر جزء باکتریهای گرم منفی، هوازی، غیر تخمیری به صورت کوکسی یا کوکوباسیل است که به عنوان پاتوژن فرصت طلب بیمارستانی به تعداد زیادی از آنتی بیوتیک ها مقاوم است. هدف از این مطالعه تعیین فراوانی بتالاکتامازهای وسیع الطیف (esbl) تیپهای oxa-2 وoxa-10 و اینتگرون کلاس یک در سویه های اسینتوباکتر بومانی جدا شده از بیماران بیمارستان امام رضا شهر تبریز می باشد.مواد و روشها: این مطالعه...
background and objective: acinetobacter baumannii is an aerobic non-motile gram-negative bacterial pathogen that is resistant to most antibiotics. carbapenems are the most common antibiotics for the treatment of infections caused by this pathogen. mechanisms of antibiotic-resistance in a. baumannii are mainly mediated by efflux pumps-lactamases. the aim of this study was to determine antibiotic...
The in vitro activity of the novel antimicrobial peptide dendrimer G3KL was evaluated against 32 Acinetobacter baumannii (including 10 OXA-23, 7 OXA-24, and 11 OXA-58 carbapenemase producers) and 35 Pseudomonas aeruginosa (including 18 VIM and 3 IMP carbapenemase producers) strains and compared to the activities of standard antibiotics. Overall, both species collections showed MIC50/90 values o...
N-acylethanolamines (NAEs) involve a family of lipid molecules existent in animal and plant, with N-palmitoylethanolamide (PEA) that arouses great attention owing to its anti-inflammatory, analgesic and neuroprotective activities. Because PEA is produced on demand and exerts pleiotropic effects, the modulation of specific amidases for NAEs (and in particular NAE-hydrolyzing acid amidase NAAA, w...
Background & Aims: Considering the importance of drug resistance among pathogenic bacteria and their treatment problems, this study aimed to determine the prevalence of extended-spectrum beta-lactamases (ESBLs), including TEM, SHV, and OXA genes among the isolated Escherichia coli and Klebsiella pneumoniae obtained from urine specimens of kidney transplant patients. Materials & Methods: The ba...
We are interested in the allosteric modulation of neuronal nicotinic acetylcholine receptors (nAChRs). We have postulated that the anthelmintic morantel (Mor) positively modulates (potentiates) rat α3β2 receptors through a site located at the β(+)/α(-) interface that is homologous to the canonical agonist site (J Neurosci 29:8734-8742, 2009). On this basis, we aimed to determine the site specif...
