conclusions considering the high prevalence of esbl genes (bla ctx-m, 87%; and bla tem, 82%), fluoroquinolones may be used as an alternative drug in treatment, although resistance to this family is increasing as well. as a result, this increasing trend should be prevented using appropriate guidelines for prescription. background escherichia coli is the most important as well as the most common ...

Objective: To investigate antimicrobial resistance mechanisms of isolated bacterial strains, and their correlation with virulence profile.Method: The cross-sectional study was conducted in January 2020 at outpatient health centres Kafrelsheikh Governorate Egypt, comprised urine samples from patients regardless age gender. Midstream were collected into sterile swaps which kept ice-cooled boxes u...

AIM The aims of this study were to investigate the phenotypic and genotypic of extended-spectrum β-lactamase (ESBL) and metallo-β-lactamases (MBLs) and determine phylogenetic background E. coli isolates from fecal samples of patients with diarrhea in Kerman, southeast of Iran. BACKGROUND The emergence of ESBLs and MBLs-producing E. coli caused problems in antibiotic treatments. E. coli strain...

BACKGROUND Infections are the major cause of morbidity and mortality in children with cancer. Gaining a favorable prognosis for these patients depends on selecting the appropriate therapy, which in turn depends on rapid and accurate microbiological diagnosis. This study employed real-time PCR (qPCR) to identify the main pathogens causing bloodstream infection (BSI) in patients treated at the Pe...

BACKGROUND CTX-M-producing Escherichia coli strains are regarded as major global pathogens. METHODOLOGY/PRINCIPAL FINDINGS The nucleotide sequence of three plasmids (pEC_B24: 73801-bp; pEC_L8: 118525-bp and pEC_L46: 144871-bp) from Escherichia coli isolates obtained from patients with urinary tract infections and one plasmid (pEC_Bactec: 92970-bp) from an Escherichia coli strain isolated from...

The presence of plasmid-mediated quinolone resistance genes [i.e., qnrA, qnrB, qnrS, aac(6')-Ib-cr, and qepA] was evaluated among 42 bla(KPC)-containing Klebsiella pneumoniae isolates collected in the eastern United States. One isolate carried the bla(KPC-3) and qnrB19 genes on the same conjugative plasmid, whereas another carried the bla(KPC-3) and qnrA1 genes on separate plasmids.

OBJECTIVES This study was designed to demonstrate the prevalence of the newly discovered carbapenem-hydrolysing class D enzymes, OXA-51-type and OXA-58, among clinical isolates of Acinetobacter spp. METHODS A total of 72 isolates from six centres were studied. Isolates were screened by PCR with specific primers for bla(OXA-51-type) and bla(OXA-58). PCR products were sequence-analysed. Plasmid...

The nucleotide sequences of 59 bla(TEM) genes encoding inhibitor-resistant TEM enzymes showed great genetic variability and were associated with different types of promoters. These findings led us to suggest an updated bla(TEM) gene nomenclature based on the origin of the bla(TEM) gene (bla(TEM-1A), bla(TEM-1B), bla(TEM-1C), bla(TEM-1D), bla(TEM-1E), and bla(TEM-1F)) and the promoter type.

OBJECTIVES To analyse the metallo-β-lactamase (MBL) genes and their genetic environments in clinical isolates of Achromobacter xylosoxidans. METHODS From January 2004 to December 2010, four MBL-producing, multidrug-resistant (MDR) A. xylosoxidans strains were isolated and analysed at a tertiary care university hospital in Japan. Species-level identification was confirmed by 16S ribosomal RNA ...

Introduction: A total of (116) diarrhea-sufficient patient samples gathered from February 15, 2019 to April 2019. Methodology: Using colonial morphology, microscopic examination, biochemical testing, and the 20 R API Enter systems, bacteria were able be identified. Ultimate "PCR" identification E. coli ("MDH" gene). Result: Rendering results obtained according morphological, cultural characters...
