Introduction : The widespread use of β -lactam antibiotic has lead to the development of resistance to this group of antibiotics in bacterial pathogens due to β -lactamase production. This study was undertaken to determine the AmpC β -lactamase production in pathogens isolated from hospitalized patients at selected university hospitals of Tehran. Materials & Methods: Non-repeat clinical iso...
OBJECTIVES Widespread use of β-lactam antibiotics could cause resistance to this group of antibiotics in pathogenic bacteria through the production of the enzyme β-lactamases. The aim of this study is to determine the molecular detection of AmpC β-lactamases among clinical Escherichia coli isolated from Ilam hospitals in Ilam, Iran. METHODS One hundred and twelve clinical isolates of E. coli ...
The widespread use of β-lactam antibiotics has lead to the development of resistance to this group of antibiotics in bacterial pathogens due to various types of β lactamase production. Amongst the mechanisms of resistance to third generation cephalosporins, production of extended spectrum β-lactamases (ESBLs) and AmpC β lactamases is the most common1. Since both ESBL and AmpC β-lactamase are en...
Resistance to 3rd generation cephalosporins in Salmonella has been attributed to the production of extended spectrum β-lactamases (ESBLs), but AmpC and KPC or metallo β-lactamase (MBL) mediated resistance have also been reported1. ESBLs reported in Salmonella spp. are the derivatives of TEM, SHV, CTX-M and PER type β-lactamase families1. We isolated Salmonella enterica ser. Typhimurium (B9903) ...
BACKGROUND Uropathogenic Escherichia coli are increasingly becoming resistant to flouroquinolones and to other commonly available antimicrobials. We sought to investigate the genetic basis for fluoroquinolone and extended spectrum beta-lactam (ESBL) resistance in 17 fluoroquinolone-resistant (MIC of levofloxacin and ciprofloxacin >32 microg/ml) E. coli isolated from patients with urinary tract ...
Introduction Extended-spectrum β-lactamases (ESBLs), including the AmpC type, are important mechanisms of resistance among Klebsiella pneumoniae and Escherichia coli isolates. Objective The aim of the study was to investigate the occurrence of AmpC-type β-lactamase producers isolated from two hospitals in Tripoli, Libya. Methods All clinical isolates (76 K. pneumoniae and 75 E. coli) collec...
abstract this paper discusses several commonly used models for strategic marketing¹ including market environmental analysis methods (i.e. swot and pest analysis) and strategic marketing tools and techniques (i.e. boston matrix and shell directional policy matrix)and shows how these models may help a firm to achieve its strategic goals. at first, the main reason for doing this research is de...
as the canon is shaped by white male standards rewriting the canonical works of literature is one of the ways through which postcolonial writers subvert the authority of the masters. writing in the language of the masters the colonized writers use the very suppressive tool in the hands of the masters i.e. their language to question the validity of their norms. regarded by most critics to be the...
The emergence and spread of resistance in Enterobacteriaceae are complicating the treatment of serious nosocomial infections and threatening to create species resistant to all currently available agents. Approximately 20% of Klebsiella pneumoniae infections and 31% of Enterobacter spp infections in intensive care units in the United States now involve strains not susceptible to third-generation...
Despite the discovery of novel beta-lactamases such as extended-spectrum beta-lactamases (ESBLs), imported AmpC, and carbapenem-hydrolyzing beta-lactamases at least a decade ago, there remains a low level of awareness of their importance and how to detect them. There is a need to increase the levels of awareness of clinical laboratories about the detection of newer beta-lactamases. Therefore, a...
