Subject:
bacteria; equipment; microfiltration; temperature; vegetables
Abstract:
... A commercial “concentrating pipette” was scrutinized from the perspective of sample volume reduction to augment native bacterial quantitation and identification within food samples. Aspects related to the elution protocol were evaluated for their impact on bacteria recovery. The results demonstrated there was no significant effect from different diluents/eluents on the relative recovery rate. Furt ...

Abstract:
... Salmonella enterica and Escherichia coli are important human pathogens that frequently contain plasmids, both large and small, carrying antibiotic resistance genes. Large conjugative plasmids are known to mobilize small Col plasmids, but less is known about the specificity of mobilization. In the current study, six S. enterica and four E. coli strains containing large plasmids were tested for thei ...

Abstract:
... Improvements in mass spectrometry technology to include instrument duty cycle, resolution, and sensitivity suggest mass spectrometry as a highly competitive alternative to conventional microbiological proteomic techniques. Targeted mass spectral analysis, sans prior empirical measurements, has begun to solely use the enormous amount of available genomic information for assay development. An in sil ...

Abstract:
... DNA sequencing and other DNA-based methods are now broadly used for detection and identification of bacterial foodborne pathogens. For the identification of foodborne bacterial pathogens, taxonomic assignments must be made to the species or even subspecies level. Long-read DNA sequencing provides finer taxonomic resolution than short-read sequencing. Here, we demonstrate the potential of long-read ...

Varying levels of CsgD-dependent curli/biofilm expression are restored to strains bearing prophage insertions in mlrA by mutation of regulatory genes affecting csgD . Our previous study identified strong biofilm- and curli-producing variants in O15 ...

Abstract:
... Biofilm formation in most Escherichia coli strains is dependent on curli fimbriae and cellulose, and the production of both varies widely among pathogenic strains. Curli and cellulose production by colonies growing on agar are often identified by their affinity for Congo red dye (CR). However, media composition and incubation temperature can affect dye affinity and impose limitations on red phenot ...
