coli and Salmonella spp. Out of 200 samples collected from retail markets Durg, Raipur, Rajnandgaon Balod districts Chhattisgarh State, 76 (38) 46 (23%) were found contaminated with E. spp., respectively. Multiple antibiotic resistant (MAR) index varied between 0.00 to 0.88 0.11 for isolates, The isolates screened phenotypically ESBL production multiplex PCR targeting blaTEM, blaSHV, andblaCTX-...

ABSTRACT       Background and Objective: Extended-spectrum beta-lactamases (ESBL) are widely produced by Escherichia coli strains. The aim of this study was to determine frequency of blaOXA-1 and blaSHV genes in E.coli strains isolated from patients hospitalized in city of Rasht, Iran.        Methods: In this cross-sectional study, ...

5 Abstract Aim: To analyse the occurrence of bla genes (blaIMP, blaVIM, blaGIM, blaSIM, blaSPM, blaPER, blaKPC, and blaOXA) responsible for carbapenemresistance, as well as the presence of cephalosporin-resistance genes (blaCTX-M, blaTEM, blaSHV and blaampC ) by polymerase chain reactions (PCRs). Methods: The study was performed on routine samples subjected to culture and antibiotics susceptibi...

Presence of extended spectrum beta-lactamases (ESBL) in bacteria is a growing health concern of global significance. The local, regional, national, and international epidemiological studies for extended spectrum beta-lactamases-producing Enterobacteriaceae and their encoding genes in foods are still incomplete. The objective of this study was to determine the occurrence of extended spectrum bet...

BACKGROUND & OBJECTIVES Information about the genetic diversity of the extended-spectrum β-lactamases (ESBLs) and the clonal relationship of the organisms causing neonatal infections is limited, particularly from India where neonatal mortality is high. This study was undertaken to investigate the molecular epidemiology and risk factors associated with neonatal septicaemia caused by ESBL-produci...

Background and Objective: Beta-lactamases are the most important factors in the resistance to beta-lactam antibiotics among gram-negative bacteria, especially Klebsiella pneumoniae. Nowadays, the prevalence of infections caused by extended-spectrum β-lactamases (ESBLs)-producing K. pneumoniae is increasing, as one of the emerging health problems throughout the world. This study aimed to investi...
