Aim: The present study was conducted to record the association of extended spectrum β-lactamases (ESBLs) producing enteric bacteria with diarrhea of poultry birds in Mizoram, India. Materials and Methods: Fecal samples were collected from poultry birds with the history of diarrhea from different parts of Mizoram. Samples were processed for isolation and identification of Escherichia coli, Salmo...

OBJECTIVES The multiresistance plasmid pKP96 from Klebsiella pneumoniae was sequenced completely and analysed concerning its genetic environment and distributing of antimicrobial resistance genes. METHODS The complete sequence of the plasmid was determined using a whole-genome shotgun approach. MICs of 13 antimicrobial agents were determined using Etests. A conjugation experiment was performe...

Abstract Background and objectives: The increase of ESBL producing E.coli can create a tremendous difficult y for the health system. These isolates leads to rapid transmission of causative genes to other clinically important bacteria and synchronously increased resistant to other antibiotics. This study was carried out to determine the prevalence of this isolate and related genes in Gorgan, Nor...

Background and purpose: Production of beta-lactamase enzymes by bacteria, especially Extended-spectrum β-lactamases (ESBLs) is one of the major problems worldwide. ESBLs are mostly located on bacterial plasmids and it is recognized that SHV, TEM, and CTX-M are prevailing among them. The aim of this study was to determine the ability to produce ESBLs genes based on molecular method among non-fer...
