Time‐Resolved Effects of Cold Atmospheric Plasma on E. coli GW‐AmxH19 Transcriptome and Proteome in an Emulated Wastewater Environment

PROTEOMICS, EarlyView.
ABSTRACT Cold atmospheric plasma (CAP) is effective against a variety of microorganisms. Here, we described effects on an Escherichia coli strain isolated from hospital wastewater caused by treatment with physical plasma. E. coli GW‐AmxH19 was incubated in artificial wastewater and treated for 15 min with CAP.

Leucine-Responsive Regulatory Protein Lrp and PapI Homologues Influence Phase Variation of CS31A Fimbriae [PDF]

Journal of Bacteriology, 2014
ABSTRACTCS31A, a K88-related surface antigen specified by theclpoperon, is a member of the type P family of adhesive factors and plays a key role in the establishment of disease caused by septicemic and enterotoxigenicEscherichia colistrains. Its expression is under the control of methylation-dependent transcriptional regulation, for which the leucine ...

Chaperone-usher fimbriae of Escherichia coli [PDF]

, 2013
Chaperone-usher (CU) fimbriae are adhesive surface organelles common to many Gram-negative bacteria. Escherichia coli genomes contain a large variety of characterised and putative CU fimbrial operons, however, the classification and annotation of ...

Nonthermal plasma approaches for combating implant‐associated infections: A compendious review

VIEW, EarlyView.
Implant‐associated infections pose serious clinical challenges. Non‐thermal plasma (NTP) modifications overcome this bottleneck in distinct ways relative to traditional sterilization methods. Gas‐phase plasmas generate highly energetic species, UV radiation and reactive oxygen/nitrogen species (RONS), which alter the implant surface properties.

Egy virulencia regulátor mutáns Salmonella enterica törzs mint kereszt-immunitást biztosító orális vakcina jelölt vizsgálata = Investigation of a virulence regulator mutant strain of Salmonella enterica as a candidate for live oral vaccine providing cross-immunity [PDF]

, 2008
Kutatásaink során egy Salmonella rfaH mutánst mint potenciális vakcina jelöltet vizsgáltunk több aspektusból. Mivel az RfaH fehérje egy transzkripciós regulátor, vizsgáltuk, hogy mely virulencia faktorokra kifejtett hatása okozza a vakcina törzs ...

Evolutionary and Epidemiological Characterization of Multidrug‐Resistant Escherichia coli Isolated From Pangolins in China

Integrative Zoology, EarlyView.
ABSTRACT Malayan pangolin populations have fallen to a critically endangered level, and illegal trafficking of wild pangolins is a global problem. Little is known about antimicrobial‐resistant bacteria (MDRB) harbored by pangolins, although pangolins are frequently consumed as food or used in traditional medicine. In this study, we report for the first

Maturation of fimbria precursor protein by exogenous gingipains inPorphyromonas gingivalisgingipain-null mutant [PDF]

FEMS Microbiology Letters, 2007
Porphyromonas gingivalis expresses several virulence factors such as fimbriae and proteases, termed gingipains, which are enzymes that process precursor fimbriae proteins. Thus, gingipain-null mutants lack mature fimbriae. Membrane vesicle-depleted supernatants (VDS) containing soluble gingipains were prepared as an exogenous gingipain fraction ...

Chaperone-usher fimbriae in a diverse selection of Gallibacterium genomes [PDF]

, 2014
BackgroundFimbriae are bacterial cell surface organelles involved in the pathogenesis of many bacterial species, including Gallibacterium anatis, in which a F17-like fimbriae of the chaperone-usher (CU) family was recently shown to be an important ...

Orchestrated molecular changes of proliferative, migratory‐fibrillar, synaptic, and postmigratory compartments align with precocious cortex‐type specification in the early human pallium

Journal of Anatomy, EarlyView.
Early human cortical development is organized by transient cellular compartments that define cortical types before mature layers form. Analysis of the human fetal pallium (7.5–15 PCW) shows distinct spatiotemporal trajectories for the archicortex, mesocortex, and neocortex, with delayed but accelerated differentiation in allocortical regions.

Porcine Milk Fat Globule Membrane Proteins that Bind to F4ac Fimbriae and prevent attachment of Escherichia coli to enterocytes [PDF]

, 2012
Post-weaning diarrhea (PWD) in pigs is caused by enterotoxigenic Escherichia coli (ETEC) which is often controlled by antibiotic feed supplements with the potential risk of generation of antibiotic resistant bacteria.
