Adenylate Cyclase Toxin from Bordetella pertussis Synergizes with Lipopolysaccharide To Promote Innate Interleukin-10 Production and Enhances the Induction of Th2 and Regulatory T Cells
(American Society for Microbiology, 2004-03)Adenylate cyclase toxin (CyaA) from Bordetella pertussis can subvert host immune responses allowing bacterial colonization. Here we have examined its adjuvant and immunomodulatory properties and the possible contribution ... -
Agricultural anaerobic digestion power plants in Ireland and Germany: policy and practice
(Wiley, 2016-08-24)The process of anaerobic digestion (AD) is valued as a carbon-neutral energy source, while simultaneously treating organic waste, making it safer for disposal or use as a fertilizer on agricultural land. The AD process in ... -
Antibacterial potential of an antimicrobial agent inspired by peroxidase-catalyzed systems
(Frontiers Media, 2017-05-02)Antibiotic resistance is an increasingly serious threat to global health. Consequently, the development of non-antibiotic based therapies and disinfectants, which avoid induction of resistance, or cross-resistance, is of ... -
An assessment of RNA content in Prymnesium parvum, Prymnesium polylepis, cf. Chattonella sp. and Karlodinium veneficum under varying environmental conditions for calibrating an RNA microarray for species detection
(Wiley, 2014-02-03)Traditional methods of identification and enumeration can be somewhat ambiguous when identifying phytoplankton that requires electron microscopic examination to verify specific morphological features. Members of the genus ... -
Biological phosphorus removal during high-rate, low-temperature, anaerobic digestion of wastewater
(Frontiers Media, 2016-03-03)We report, for the first time, extensive biologically mediated phosphate removal from wastewater during high-rate anaerobic digestion (AD). A hybrid sludge bed/fixed-film (packed pumice stone) reactor was employed for ... -
Bioreactor scalability: laboratory-scale bioreactor design influences performance, ecology, and community physiology in expanded granular sludge bed bioreactors
(Frontiers Media, 2017)Studies investigating the feasibility of new, or improved, biotechnologies, such as wastewater treatment digesters, inevitably start with laboratory-scale trials. However, it is rarely determined whether laboratory-scale ... -
Bordetella pertussis expresses a functional type III secretion system that subverts protective innate and adaptive immune responses
(American Society for Microbiology, 2008-01)Certain bacteria use a type III secretion system (TTSS) to deliver effector proteins that interfere with cell function into host cells. While transcription of genes encoding TTSS components has been demonstrated, studies ... -
Carboxylic acids production and electrosynthetic microbial community evolution under different CO2 feeding regimes
(Elsevier, 2020-10-15)Microbial electrosynthesis (MES) is a potential technology for CO2 recycling, but insufficient information is available on the microbial interactions underpinning electrochemically-assisted reactions. In this study, a MES ... -
Cold adaptation and replicable microbial community development during long-term low-temperature anaerobic digestion treatment of synthetic sewage
(Oxford University Press, 2018-05-25)The development and activity of a cold-adapting microbial community was monitored during low-temperature anaerobic digestion (LtAD) treatment of wastewater. Two replicate hybrid anaerobic sludge bed-fixed-film reactors ... -
Comparative genome analysis identifies novel nucleic acid diagnostic targets for use in the specific detection of Haemophilus influenzae
(Elsevier, 2015-06-23)Haemophilus influenzae is recognised as an important human pathogen associated with invasive infections, including bloodstream infection and meningitis. Currently used molecular-based diagnostic assays lack specificity in ... -
Comparison of established diagnostic methodologies and a novel bacterial smpB real-time PCR assay for the specific detection of haemophilus influenzae associated with respiratory tract infections
(American Society for Microbiology, 2015-06-23)Haemophilus influenzae is a significant causative agent of respiratory tract infections (RTI) worldwide. The development of a rapid H. influenzae diagnostic assay that would allow for the implementation of infection control ... -
Competition between the Yops of Yersinia enterocolitica for delivery into eukaryotic cells: Role of the SycE chaperone binding domain of YopE
(American Society for Microbiology, 2000-09)A type III secretion-translocation system allows Yersinia adhering at the surface of animal cells to deliver a cocktail of effector Yops (YopH, -O, -P, -E, -M, and -T) into the cytosol of these cells. Residues or codons 1 ... -
Continuous culture of Escherichia coli, under selective pressure by a novel antimicrobial complex, does not result in development of resistance
(Nature Research, 2019-02-20)We attempted to generate de novo resistance to a newly described biocidal complex, ITC (iodo-thiocyanate complex), and to levofloxacin (LVX) in Escherichia coli ATCC 25922, by means of selective chemostat culture. We ... -
Contrasting responses to nutrient enrichment of prokaryotic communities collected from deep sea sites in the Southern Ocean
(MDPI Open-Access Journals, 2013-09-13)Abstract: Deep water samples (ca. 4,200 m) were taken from two hydrologically-similar sites around the Crozet islands with highly contrasting surface water productivities. Site M5 was characteristic of high productivity ... -
Control of transfer and weak closure in fusion systems
(2010)We show that K¿ and K¿ control transfer in every fusion system on a finite p-group when p ¿ 5, and that they control weak closure of elements in every fusion system on a finite p-group when p ¿ 3. This generalizes resultsof ... -
Cross platform standardisation of an experimental pipeline for use in the identification of dysregulated human circulating MiRNAs
(Public Library of Science, 2015-09-10)Micro RNAs (miRNAs) are a class of highly conserved small non-coding RNAs that play an important part in the post-transcriptional regulation of gene expression. A substantial number of miRNAs have been proposed as biomarkers ... -
The dairy biorefinery: Integrating treatment processes for cheese whey valorisation
(Elsevier, 2020-08-28)With an estimated worldwide production of 190 billion kg per year, and due to its high organic load, cheese whey represents a huge opportunity for bioenergy and biochemicals production. Several physical, chemical and ... -
Determination of survival of wildtype and mutant Escherichia coli in soil
(Bio-protocol, 2017-07-20)E. coli resides in the gastrointestinal tract of humans and other warm-blooded animals but recent studies have shown that E. coli can persist and grow in various external environments including soil. The general stress ... -
