A broad community of independent scientific researchers and scholars challenges recent claims a consensus over the safety genetically modified organisms (GMOs). In following joint statement, claimed is shown to be an artificial construct that has been falsely perpetuated through diverse fora. Irrespective contradictory evidence in refereed literature, as documented below, claim there now on GMOs continues widely often uncritically aired. For decades, hotly controversial topic much debated...
Biocides, such as herbicides, are routinely tested for toxicity but not sublethal effects on microbes. Many biocides known to induce an adaptive multiple-antibiotic resistance phenotype. This can be due either increase in the expression of efflux pumps, a reduced synthesis outer membrane porins, or both. Exposures Escherichia coli and Salmonella enterica serovar Typhimurium commercial formulations three herbicides-dicamba (Kamba), 2,4-dichlorophenoxyacetic acid (2,4-D), glyphosate...
Bacteriophages infecting Salmonella spp. were isolated from sewage using soft agar overlays containing three serovars and assessed with regard to their potential control food-borne salmonellae. Two distinct phages, as defined by plaque morphology, structure host range, obtained a single sample of screened sewage. Phage FGCSSa1 had the broadest range six eight isolates neither two Escherichia coli isolates. Under optimal growth conditions for S. Enteritidis PT160, phage infection resulted in...
An agroecosystem is constrained by environmental possibility and social choices, mainly in the form of government policies. To be sustainable, an requires production systems that are resilient to natural stressors such as disease, pests, drought, wind salinity, human constructed economic cycles trade barriers. The world becoming increasingly reliant on concentrated exporting agroecosystems for staple crops, vulnerable national local decisions affect resilience these systems. We chronicle...
Antimicrobial resistance (AMR) threatens human and ecological health worldwide. Unless major changes occur across the human, animal environmental sectors, problem will continue to expand. An important component of AMR that deserves greater attention is influence emerging organic contaminants (EOCs) – ubiquitous compounds found, amongst others, in pharmaceuticals, personal care products, food, industrial agricultural plastics building materials. EOCs are widely used can accumulate environment...
Postsegregational killing (PSK) systems consist of a tightly linked toxin–antitoxin pair. Antitoxin must be continually produced to prevent the longer lived toxin from cell. PSK on plasmids are widely believed benefit plasmid by ensuring its stable vertical inheritance. However, experimental tests this “stability” hypothesis were not consistent with predictions. We suggest an alternative explain evolution PSK: that have been selected through benefiting host in environments where compete...
Antibiotic resistance in our pathogens is medicine's climate change: caused by human activity, and resulting more extreme outcomes. Resistance emerges microbial populations when antibiotics act on phenotypic variance within the population. This can arise from either genotypic diversity (resulting a mutation or horizontal gene transfer), differences expression due to environmental variation, referred as adaptive resistance. Adaptive changes increase fitness allowing bacteria survive at higher...
Abstract TiO 2 photocatalyst is of interest for antimicrobial coatings on hospital touch-surfaces. Recent research has focused visible spectrum enhancement photocatalytic activity. Here, we report with a high degree nanostructure, deposited stainless steel as solid layer more than 10 μm thick by pulsed-pressure-MOCVD. The coating exhibits rarely-reported microstructure comprising anatase and rutile in composite amorphous carbon. Columnar single crystals are segmented into 15–20 nm plates,...
Changing the nature, kind and quantity of particular regulatory-RNA molecules through genetic engineering can create biosafety risks. While some genetically modified organisms (GMOs) are intended to produce new molecules, these may also arise in other GMOs not express them. To characterise, assess then mitigate potential adverse effects arising from changes RNA requires changing current approaches food or environmental risk assessments GMOs. We document assessment advice offered government...
Herbicides are frequently released into both rural and urban environments. Commercial herbicide formulations induce adaptive changes in the way bacteria respond to antibiotics. Salmonella enterica sv. Typhimurium Escherichia coli were exposed common co-formulants of formulations, S. was active ingredients dicamba, 2,4-D glyphosate determine what commercial caused this effect. Co-formulants Tween80 carboxymethyl cellulose induced response, but pattern responses differed from ingredients,...
Helicobacter pylori is highly susceptible to bismuth, a heavy metal with antimicrobial activity linked its effect on bacterial iron uptake. Three strains of H. were analyzed for indicators limitation following exposure the MIC colloidal bismuth subcitrate (MIC(CBS)). Similar morphologic and outer membrane changes observed growth in iron-limiting medium at MIC(CBS) that inhibited all three strains. These changes, which also iron-limited bacteria, alleviated by addition cultures. ATP levels,...
To isolate and characterize bacteriophages (phages) that infect the foodborne pathogen Bacillus cereus.Two phages were isolated from soil based on their ability to form plaques four indicator hosts including thuringiensis subsp. israelensis, three isolates of B. cereus. The purified characterized by morphology, host range, single-step growth curves restriction enzyme digestion profiles. appeared be Myoviridae family structure in electron micrographs. lysed bacteria several species, produced...
CRISPR/Cas9, a potent genetic engineering tool widely adopted in agriculture, is capable of introducing new characteristics into plants on large scale and without conventional breeding methods. Despite its remarkable efficiency, concerns have arisen regarding unintended consequences uncontrolled environments. Our aim was to assess potential activity organisms that could be exposed genome editing We developed three scenarios, using irrigation, fumigation fertilization as delivery methods,...
