introduction: biofilm producing staphylococcus aureus is known as one of the major causative agents of infections, failure of implanted devices and persistent infection among hospitalized patients . the aim of the present study was to determine the frequency of biofilm producing s. aureus isolates amongst the clinical specimens. methods: this cross-sectional study was conducted during 2012 to 2...

conclusions the rapid dissemination of non clonal multi-resistant ctx-m-1 producing e. coli isolates approved the need for further studies in our medical centers. results a total of 140(70%) non-duplicate esbl positive e. coli were determined. imipenem and amikacin were effective against 100% and 85% of all tested isolates respectively. co-resistance of esbl positive isolates to erythromycin, t...

Objective: There are few therapeutic options for treatment of multidrug resistant Klebsiella pneumoniae isolates as a hospital infectious agent (nosocomial infection). The aim of this study was to evaluate the antibacterial activity of Zataria multiflora Boiss extracts against ESBL-producing Klebsiella pneumoniae strains. Materials and Methods: This study was conducted on 100 K. pneumoniae isola...

Objective(s) Extensive use of quinolones has been associated with raising level of resistance. In the current, we focused on assessing the prevalence of Escherichia coli resistance to quinolones and frequency of qnrA, qnrB and qnrS in non ESBLs (extended spectrum beta-lactamases) and ESBLs producing E. coli with blaSHV and blaTEM. Materials and Methods One hundred and fifty E. coli isolates ...

The present study was conducted to detect the occurrence, serotype, genotype, phylogenetic relationship and antimicrobial resistance pattern of STEC from healthy goats of West Bengal, India. From the 125 faecal samples collected from healthy goats, 245 isolates were identified as Escherichia coli. The E. coli harbouring any gene for Shiga toxins (stx1/stx2) was detected in 36 (14.7%) of the 245...

background :   this study was to evaluate the prevalence of ctx-mand tem type esbls-producing k. pneumoniae and determination of mdr, xdr, and pdr phenotypes of these isolates as well as find out the genetic relationship and molecular typing of these isolates using phenotypic and genotypic methods. methods :   non-repetitive 96 k. pneumonia isolates were isolated from hospitalized patients in a...
