A multiple antibiotic-resistant enterobacter cloacae strain isolated from a bioethanol fermentation facility.

ABSTRACT: An Enterobacter cloacae strain (E. cloacae F3S3) that was collected as part of a project to assess antibiotic resistance among bacteria isolated from bioethanol fermentation facilities demonstrated high levels of resistance to antibiotics added prophylactically to bioethanol fermentors. PCR assays revealed the presence of canonical genes encoding resistance to penicillin (ampC) and erythromycin (ermG). Assays measuring biofilm formation under antibiotic stress indicated that erythromycin induced biofilm formation in E. cloacae F3S3. Planktonic growth and biofilm formation were observed at a high ethanol content, indicating E. cloacae F3S3 can persist in a bioethanol fermentor under the highly variable environmental conditions found in fermentors.

Antibiotic failure mediated by a resistant subpopulation in Enterobacter cloacae.

Project description:Antibiotic resistance is a major public health threat, further complicated by unexplained treatment failures caused by bacteria that appear antibiotic susceptible. We describe an Enterobacter cloacae isolate harbouring a minor subpopulation that is highly resistant to the last-line antibiotic colistin. This subpopulation was distinct from persisters, became predominant in colistin, returned to baseline after colistin removal and was dependent on the histidine kinase PhoQ. During murine infection, but in the absence of colistin, innate immune defences led to an increased frequency of the resistant subpopulation, leading to inefficacy of subsequent colistin therapy. An isolate with a lower-frequency colistin-resistant subpopulation similarly caused treatment failure but was misclassified as susceptible by current diagnostics once cultured outside the host. These data demonstrate the ability of low-frequency bacterial subpopulations to contribute to clinically relevant antibiotic resistance, elucidating an enigmatic cause of antibiotic treatment failure and highlighting the critical need for more sensitive diagnostics.

Draft genome sequence data of a tigecycline-resistant Enterobacter cloacae ST93 clinical strain isolated from bloodstream infection.

Project description:Here we report data on the draft genome sequence of a tigecycline-resistant Enterobacter cloacae ST93 clinical isolate TREC1 producing KPC-2 carbapenemase from China. The draft genome sequence of E. cloacae TREC1 consisted of 74 contigs that comprised 5,322,835?bp, and the overall GC content of this strain amounted to 54.63%. In total, 57 tRNA genes, 5 rRNA operons and 5108 protein-coding sequences were identified in the genome. TREC1 belongs to sequence type ST93. Nineteen antimicrobial resistance genes were confirmed. Antimicrobial susceptibility testing revealed that besides colistin this isolate is resistant to all antibiotics including tigecycline. This Whole Genome Shotgun project has been deposited at DDBJ/EMBL/GenBank under the accession number PJZE00000000. (http://www.ncbi.nlm.nih.gov/nuccore/PJZE00000000).

Draft Genome Sequences of Nonclinical and Clinical Enterobacter cloacae Isolates Exhibiting Multiple Antibiotic Resistance and Virulence Factors.

Project description:Enterobacter spp. have been implicated as opportunistic pathogens which over the years have gained resistance toward most of the available therapeutic drugs. We sequenced two multidrug-resistant Enterobacter cloacae isolates harboring multiple efflux pump genes. These isolates exhibited strain-specific modulation of efflux pump protein expression.

Molecular characterization of metallo-β-lactamase- producing carbapenem-resistant Enterobacter cloacae complex isolated in Heilongjiang Province of China.

Project description:BACKGROUND:Enterobacter cloacae complex (ECC) is one of the most common extended-spectrum β-lactamase and carbapenemase-producing pathogen that threatens millions of the elderly and vulnerable sick persons. The objective of this study was to perform the molecular characteristics of the carbapenem-resistant E. cloacae complex (CREC) emerged in Heilongjiang Province of China. METHODS:Six CREC strains were isolated from the patients with infectious diseases. The identities of ECC isolates were confirmed by sequencing the polymerase chain reaction (PCR) products of 16S rRNA gene. The characterization of the CREC isolates were analyzed by sequencing PCR products of the carbapenemase, ampC and fluoroquinolone resistance genes and performing multilocus sequence typing (MLST), pulsed-field gel electrophoresis (PFGE) and whole genome sequencing. RESULTS:All 6 isolates harbored multiple resistance genes. Of them, 5 carried metallo-β-lactamases and one was blaKPC-2-positive. The levofloxacin and ciprofloxacin-resistant strains had substitutions of gyrA83, gyrA87, and parC80 in the quinolone-resistance determining regions. The MLST analyses revealed that 6 isolates belonged to five sequence types (ST520, ST528, ST1119, ST1120, and ST93) while the PFGE patterns of the isolates fallen into four clusters. The strain ST1120 was found to carry two separated plasmids that encode blaNDM-1 and blaIMP-4. CONCLUSIONS:Our study, for the first time, identified a CREC strain that co-produces blaNDM-1 and blaIMP-4 in the Northeast China. Our finding emphasizes an urgent need for more intensive surveillance and precaution measures to prevent the CERC spread.

Carbapenem- and Colistin-Resistant Enterobacter cloacae from Delta, Colorado, in 2015.

Project description:Resistance to carbapenems in Enterobacteriaceae is a clinical problem of growing significance. Difficulty in treating multidrug-resistant Gram-negative organisms with conventional antibiotics has led to a renewed and increasing use of polymyxin compounds, such as colistin. Here, we report the isolation of carbapenem- and colistin-resistant Enterobacter cloacae from a polymicrobial lower extremity wound in an ambulatory patient. Whole-genome sequencing demonstrated the presence of chromosomal blaIMI-1 and blaAmpC, as well as numerous efflux pump genes.

resistome analysis of Enterobacter cloacae CY01, an extensively drug-resistant strain producing VIM-1 metallo-β-lactamase from China.

Project description:Resistome analysis of clinical VIM-1-producing Enterobacter cloacae strain CY01 from China revealed the presence of multiple resistance determinants. Two resistance plasmids were identified in CY01. The pCY-VIM plasmid was 14 kb in size and possessed a replicase gene (repA), a gene cluster encoding the partitioning function (parABC), and a carbapenemase gene (blaVIM-1). Another 5.9-kb plasmid, pCY-MdT, with an aac(6')-Ib gene, was very closely related (13 nucleotide differences) to pMdT1, a ColE1 plasmid carrying aac(6')-Ib-cr4.
