Identification of β-Lactamase-Negative-Ampicillin Resistance Strains of Escherichia coli in 150 Isolates from Urinary Tract Infection and Fecal Flora in Kerman
β-lactamases are enzymes which inactivate the β-lactam antibacterial agents and are one of the major causes of resistance against these drugs. Recently there are reports on the isolation of bacteria which does not produce β-lactamase, but are resistant to penicillins. In the present study, β-laclamase production was determined using iodometric method on 150 ampicillin resistance Escherichia col...
متن کاملتعیین الگوی مقاومت ایزولههای بالینی اشریشیاکلی مولد بتالاکتامازهای وسیعالطیف نوع AmpC براساس خصوصیات فنوتیپی و ژنوتیپی
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...
متن کاملSurvey of hospital environment regarding the presence of Staphylococcus aureus producing β-lactamase
Staphylococcus aureus is a common cause of hospital-acquired infections. This bacterium is resistant to β-lactam antibiotics. The aim of this study was to evaluate the prevalence of S. aureus strains producing enzymes capable of destroying β-lactam antibiotics in a hospital environment. This descriptive and analytic study was performed in Besat Hospital, Sanandaj, Iran, 2016, on 158 swabs colle...
متن کاملPrevalence of Extended-Spectrum β-lactamase and Integron Gene Carriage in Multidrug-Resistant Klebsiella Species Isolated from Outpatients in Yazd, Iran
Background: Community-acquired infections by multidrug-resistant (MDR), extended-spectrum β-lactamase (ESBL) producing Klebsiella species (Klebsiella spp.) is of major concern worldwide. Antibiotic resistance, production of extended-spectrum β-lactamases (ESBLs), and carbapenemases, as well as the presence of classes 1, 2, and 3 integrons in outpatient isolates of Klebsiella collected from Yazd...
متن کاملQuantum Mechanical Approach for the Catalytic Mechanism of Dinuclear Zinc Metallo-β-lactamase by Penicillin and Cephalexin: Kinetic and Thermodynamic Points of View
Metallo-β-lactamases (MβL) catalyzing the hydrolytic cleavage of the four-membered β-lactam ring in broad spectrum of antibiotics and therefore inactivating the drug; However, the mechanism of these enzymes is still not well understood. Electronic structure and electronic energy of metallo-β-lactamase active center, two inhibitors of this enzyme including penicillin and cephalexin, and differen...
