Characterization of a vancomycin-resistant Enterococcus faecium isolate and a vancomycin-susceptible E. faecium isolate from the same blood culture

Objectives: To characterize two Enterococcus faecium isolates with different resistance phenotypes obtained from the same blood culture. Methods: The isolates were identified by MALDI-TOF MS and antimicrobial susceptibility testing (AST) was performed using a VITEK (R) 2 AST P592 card and Etest. WGS was performed on the MiSeq and MinION sequencer platforms. Core-genome MLST (cgMLST) and seven-Loci MLST were performed. Plasmid anaLysis was performed using S1-PFGE followed by Southern-blot hybridization. Results: Both E. faecium isolates were ST203. AST revealed that one was a vancomycin-resistant E. faecium (VREfm) isolate and the other was a vancomycin-susceptible E. faecium (VSEfm) isolate. The VREfm isolate harboured the vanA gene cluster as part of a Tn1546-type transposon encoded on a 49 kb multireplicon (repl, rep2 and rep7a) plasmid (pAML0157.1). On the same plasmid, ant(6)-Ia, cat-Like and erm(B) were encoded. The VSEfm isolate harboured a rep2 plasmid (pAML0158.1), 12 kb in size, which was present in full length as part of pAML0157.1 from the VREfm isolate. The vanA-encoding pAML0157.1 was a chimera of the rep2 pAML0158.1 and a second DNA segment harbouring vanA, ant(6)-Ia, erm(B) and cat-Like, as well as the replicons repl and rep7a. By cgMLST analysis, the VREfm and VSEfm isolates were identical. Conclusions: Our results demonstrate that the VREfm and VSEfm blood culture isolates represented ST203 and were identical. The investigated heterogeneous resistance phenotypes resulted from the acquisition or Loss of plasmid segments in the enterococcal isolates. These data illustrate that mobile genetic elements may contribute to the spread of vancomycin resistance among enterococci and to the genotypic and phenotypic variation within clonal isolates

CobWeb 1.0: machine learning toolbox for tomographic imaging

Despite the availability of both commercial and open-source software, an ideal tool for digital rock physics analysis for accurate automatic image analysis at ambient computational performance is difficult to pinpoint. More often, image segmentation is driven manually, where the performance remains limited to two phases. Discrepancies due to artefacts cause inaccuracies in image analysis. To overcome these problems, we have developed CobWeb 1.0, which is automated and explicitly tailored for accurate greyscale (multiphase) image segmentation using unsupervised and supervised machine learning techniques. In this study, we demonstrate image segmentation using unsupervised machine learning techniques. The simple and intuitive layout of the graphical user interface enables easy access to perform image enhancement and image segmentation, and further to obtain the accuracy of different segmented classes. The graphical user interface enables not only processing of a full 3-D digital rock dataset but also provides a quick and easy region-of-interest selection, where a representative elementary volume can be extracted and processed. The CobWeb software package covers image processing and machine learning libraries of MATLAB® used for image enhancement and image segmentation operations, which are compiled into series of Windows-executable binaries. Segmentation can be performed using unsupervised, supervised and ensemble classification tools. Additionally, based on the segmented phases, geometrical parameters such as pore size distribution, relative porosity trends and volume fraction can be calculated and visualized. The CobWeb software allows the export of data to various formats such as ParaView (.vtk), DSI Studio (.fib) for visualization and animation, and Microsoft® Excel and MATLAB® for numerical calculation and simulations. The capability of this new software is verified using high-resolution synchrotron tomography datasets, as well as lab-based (cone-beam) X-ray microtomography datasets. Regardless of the high spatial resolution (submicrometre), the synchrotron dataset contained edge enhancement artefacts which were eliminated using a novel dual filtering and dual segmentation procedure

Susceptibility of Clinical Enterobacterales Isolates With Common and Rare Carbapenemases to Mecillinam

Purpose: To investigate the susceptibility of carbapenemase-producing Enterobacterales (CPE) to mecillinam based on the recently updated European Committee on Antimicrobial Susceptibility Testing (EUCAST) breakpoints for uncomplicated Urinary Tract Infection (uUTI). Methods: The challenge collection consisted of 105 molecularly characterized Enterobacterales [Klebsiella spp. (N = 49), Escherichia coli (N = 30), Enterobacter cloacae (n = 13), Citrobacter freundii (N = 9), Proteus mirabilis (N = 3), and Raoultella ornithinolytica (N = 1)]. Isolates produced OXA-48 (N = 18), OXA-48-like (N = 18), VIM (N = 22), NDM (N = 22), KPC (N = 12), IMI (N = 9), IMP (N = 6), GES (N = 1), OXA-58 (N = 2) or combinations thereof (N = 5). MICs of carbapenems were determined by agar gradient diffusion (AGD). MICs of mecillinam were assessed by agar dilution (reference method) and compared to disk diffusion (DD) and AGD. Results: Overall 23/105 CPE (21.9%) were susceptible to mecillinam. Susceptibility was observed in E. coli (N = 12), E. cloacae (N = 7), and Klebsiella pneumoniae (N = 4) producing IMI, OXA-48, OXA-48-like, and NDM-1 carbapenemases. MIC50 for mecillinam in all isolates was 128 mg/L while MIC50 for meropenem was 8 mg/L. Lower MICs for mecillinam were found in IMI (MIC50 8 mg/L) and OXA-48-like (MIC50 16 mg/L) producers. The comparison of the different susceptibility methods showed very major errors of 12.2% with AGD and 8.5% with disk diffusion when compared to the reference method. Conclusion: Mecillinam susceptibility was restricted to isolates producing IMI-, OXA-48-like, and NDM-1 carbapenemases and was documented despite high carbapenem MICs in some isolates. Mecillinam could be a promising oral antimicrobial in uUTI caused by E. coli and E. cloacae isolates carrying IMI- and OXA-48-like carbapenemases; however, susceptibility testing by AGD and disk diffusion remains problematic

Gaussia princeps luciferase (Gluc) as reporter for transcriptional activity, protein secretion and protein-protein interactions in Salmonella enterica serovar Typhimurium

Gaussia princeps luciferase (Gluc) is widely used as a reporter in eukaryotes, but data about its applicability in bacteria is very limited. Here we show that a codon-optimized Gluc gene can be efficiently expressed in Salmonella enterica sv. Typhimurium (S. Typhimurium). To test different Gluc variants as transcriptional reporters, we used the siiA promoter of Salmonella Pathogenicity Island (SPI)-4 driving expression of either episomal or chromosomally integrated Gluc. Most reliable results were obtained from lysates of single-copy Gluc reporter strains. Given the small size, high activity and co-factor independence of Gluc, it might be especially suited to monitor secretion of bacterial proteins. We demonstrate its usefulness by luminescence detection of fusion proteins of Gluc and C-terminal portions of the SPI-4-encoded, type I-secreted adhesin SiiE in supernatants. The SiiE C-terminal moiety including immunoglobulin (Ig) domain 53 is essential and sufficient mediating type I-dependent secretion of Gluc. In eukaryotes, protein-protein interaction studies based on split Gluc protein complementation assays (PCA) could be established. We adapted these methods for use in Salmonella, demonstrating the interaction between the SPI-1-encoded effector SipA and its cognate secretion chaperone InvB. In conclusion, the versatile Gluc can be used to address a variety of biological questions, thus representing a valuable addition to the toolbox of modern molecular biology and microbiology
