Abstract:
AIM: The present study investigates the production of extended-spectrum beta-lactamases (ESBL) and the formation of biofilm among different bacterial pathogens. METHODS: The study conducted prospective analysis on bacteria isolates (Gram-negative) from patients who have diagnosed with infections with bacteria between October 2020 and January 2022. RESULTS: The results showed that there were 53 biofilm producers in Escherichia coli. In contrast, Pseudomonas aeruginosa was observed to have the highest percentage, with 32/40 (80%) isolates being biofilm producers. The least number of isolates wer

Abstract:
Extended-spectrum β-lactamases (ESBL) in enterobacteria are recognized worldwide as a great hospital problem. In this study, 127 ESBL-producing Enterobacteriaceae isolated in one year from inpatients and outpatients at a public teaching hospital at São Paulo, Brazil, were submitted to analysis by PCR with specific primers for blaSHV, blaTEM and blaCTX-M genes. From the 127 isolates, 96 (75.6%) Klebsiella pneumoniae, 12 (9.3%) Escherichia coli, 8 (6.2%) Morganella morganii, 3 (2.3%) Proteus mirabilis, 2 (1.6%) Klebsiella oxytoca, 2 (1.6%) Providencia rettgeri, 2 (1.6%) Providencia stuartti, 1 (

Abstract:
Mesophilic Morganella morganii (n=6) and psychrotolerant M. morganii-like isolates from various seafoods (n=13), as well as clinical M. morganii isolates (n=3), were characterized by using a polyphasic approach including multi-locus sequencing. Based on the phylogenetic analysis, the 22 strains were divided into two distinct groups comprising mesophilic and psychrotolerant isolates, respectively. This classification was supported by DNA–DNA hybridization studies, whereby a psychrotolerant isolate (strain U2/3T) showed 41.0 and 17.8 % relatedness to the type strains of the mesophilic species Mo

Introduction. The bla CTX-M-3 gene has rarely been reported in Morganella morganii strains and its genetic environment has not yet been investigated. Aim. To identify the bla CTX-M-3 gene in M. morganii isolated from swine and characterize its genetic environment. Methodology. A M. morganii isolate (named MM1L5) from a deceased swine was identified using matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) and subjected to antimicrobial susceptibility testing. The bla genes were detected and then the genetic location and environment of bla CTX-M-3 were in

Abstract:
Morganella morganii, a spoilage bacterium in fermented foods, produces harmful biogenic amines (BAs). Although Lactiplantibacillus plantarum is widely used to inhibit spoilage bacteria, the inhibition pattern and inhibition mechanism of M. morganii by Lpb. plantarum are not well studied. In this study, we analysed the effects of the addition of Lpb. plantarum cell-free supernatant (CFS) on the growth and BA accumulation of M. morganii and revealed the mechanisms of changes in different BAs by using RNA sequencing transcriptome analysis. The results showed that Lpb. plantarum CFS could signific

An antagonism was observed between cefoxitin and aztreonam by the diffusion method. Transformation of the transconjugant E. coli strain with plasmid pNH5 carrying the ampD gene (whose product decreases the level of expression of ampC) resulted in an eightfold decrease in the MIC of cefoxitin.

Morganella morganii is a Gram-negative opportunistic Enterobacteriaceae pathogen inherently resistant to colistin. This species causes various clinical and community-acquired infections. This study investigated the virulence factors, resistance mechanisms, functional pathways, and comparative genomic analysis of M. morganii strain UM869 with 79 publicly available genomes. The multidrug resistance strain UM869 harbored 65 genes associated with 30 virulence factors, including efflux pump, hemolysin, urease, adherence, toxin, and endotoxin.

Abstract Through this investigation, we establish the mechanism and physical characterization of zinc (II) sequestration by Morganella morganii ACZ05 strain, which was isolated and characterized from soil polluted by effluents from electroplating industries. As far as we know, there is very little literature concerning zinc biosorption using an environmental strain of M. morganii. The SEM analysis shows the dark porous gaps in the aggregated cell-matrix of test bacterial biomass which is inferred as water channels usually seen in biofilms, as compared to metal-unexposed control.

Abstract:
The purpose of this study was to characterize blaCTX-M plasmids originating from bovine Escherichia coli and investigate their contribution to bacterial host fitness. In this study 52 bovine Escherichia coli strains collected between March and October 2007 encoding blaCTX-M, an extended spectrum β-lactamase (ESBL) gene conferring resistance to 3rd generation cephalosporins, were characterized. The majority of strains belonged to E. coli commensal phylogroups A and B1 expressing a multi-drug resistance (MDR) phenotype and harboured multiple plasmids of which 90% were transferred by conjugation.
