Immunogenicity characterization of genetically fused or chemically conjugated heat-stable toxin (STa) toxoids of enterotoxigenic Escherichia coli (ETEC) in mice and pigs.

FEMS Microbiol Lett 2019 Feb 17. Epub 2019 Feb 17.

Department of Diagnostic Medicine/Pathobiology, Kansas State University College of Veterinary Medicine, Manhattan, Kansas, USA.

Enterotoxigenic Escherichia coli (ETEC) producing type Ib heat-stable toxin (STa) are a top cause of children's diarrhea and travelers' diarrhea, thus STa needs to be targeted in ETEC vaccine development. However, since this 19-amino acid STa is poorly immunogenic, the effort to genetically fuse or chemically couple to carrier proteins has been made to enhance STa immunogenicity. In this study, we selected one genetic fusion and one chemical conjugate to comparatively evaluate STa immunogenicity. Read More

Maria Wiese

FEMS Microbiol Lett 2019 Feb 15. Epub 2019 Feb 15.

Department of Food Science, University of Copenhagen, Frederiksberg, Denmark.

The increasing efforts to substitute antibiotics and improve animal health combined with the acknowledgement of the role of gut microbiota in health, have led to an elevated interest in the understanding on how fibre with prebiotic potential, such as pectin, can improve animal growth and health via direct or gut microbiota mediated effects. Various reports exist on the antiviral and antibacterial effects of pectin, as well as its potency as a modulator of the immune response and gut microbial community. Comprehensive insights into the potential of pectin to improve animal growth and health are currently still hampered by heterogeneity in the design of studies. Read More

FEMS Microbiol Lett 2019 Feb;366(3)

School of Life and Environmental Sciences, Molecular Bioscience Building G08, Cnr Maze Crescent and Butlin Avenue, The University of Sydney, NSW 2006, Australia.

The insertion sequence IS26 plays a major role in the mobilization, expression and dissemination of antibiotic resistance genes in Gram-negative bacteria. Though IS26 is abundant in sequenced genomes and in plasmids that harbour antibiotic resistance genes, only a few minor variations in the IS26 sequence have been recorded. The most common variant, IS26* (also known as IS15Δ1), encodes a Tnp26 transposase with a single amino acid substitution, G184N in the catalytic domain. Read More

Vaginal microbiota transplantation for the treatment of bacterial vaginosis: A conceptual analysis.

FEMS Microbiol Lett 2019 Jan 31. Epub 2019 Jan 31.

Institute of Translational Medicine, Nanchang University, Nanchang, Jiangxi 330031, PR China.

Bacterial vaginosis (BV), caused by the vaginal dysbacteriosis as well as the excessive growth of pathogenic bacteria, is a pathological condition of the vagina; its treatment using the antibiotics metronidazole or clindamycin often causes high recurrence rates. Considering the similar physiological environments of the intestinal tract and vaginal tract, as well as the pathological mechanism of intestinal infection and vaginal infection, we first propose the conception of vaginal microbiota transplantation (VMT) and discuss its potential use in BV. This review focuses on the pathology of BV and the side effects caused by its standardised treatment. Read More

Microbial uptake by the respiratory epithelium: Outcomes for host and pathogen.

FEMS Microbiol Rev 2019 Jan 18. Epub 2019 Jan 18.

Manchester Fungal Infection Group, Faculty of Biology, Medicine and Health, University of Manchester, M13 9NT, UK.

Intracellular occupancy of the respiratory epithelium is a useful pathogenic strategy facilitating microbial replication and evasion of professional phagocytes or circulating antimicrobial drugs. A less appreciated but growing body of evidence indicates that the airway epithelium also plays a crucial role in host defence against inhaled pathogens, by promoting ingestion and quelling of microorganisms, processes which can become subverted to favour pathogen activities and promote respiratory disease.To achieve a deeper understanding of beneficial and deleterious activities of respiratory epithelia during antimicrobial defence, we have comprehensively surveyed all current knowledge on airway epithelial uptake of bacterial and fungal pathogens.

NIOZ, Royal Netherlands Institute for Sea Research, Department of Marine Microbiology and Biogeochemistry, and Utrecht University, P.O. Box 59, NL-1790 AB Den Burg, The Netherlands.

Archaea-a primary domain of life besides Bacteria-have for a long time been regarded as peculiar organisms that play marginal roles in biogeochemical cycles. However, this picture changed with the discovery of a large diversity of archaea in non-extreme environments enabled by the use of cultivation-independent methods. These approaches have allowed the reconstruction of genomes of uncultivated microorganisms and revealed that archaea are diverse and broadly distributed in the biosphere and seemingly include a large diversity of putative symbiotic organisms, most of which belong to the tentative archaeal superphylum referred to as DPANN.

The genetic diversity and evolution of diatom-diazotroph associations highlights traits favoring symbiont integration.

FEMS Microbiol Lett 2019 Jan;366(2)

Stockholm University, Department of Ecology, Environment and Plant Sciences, Stockholm, 10691, Sweden.

Diatom diazotroph associations (DDAs) are a widespread marine planktonic symbiosis between several diatom genera and di-nitrogen (N2)-fixing bacteria. Combining single cell confocal microscopy observations and molecular genetic approaches on individual field collected cells, we determined the phylogenetic diversity, distribution and evolution of the DDAs. Confocal analyses coupled with 3-D imaging re-evaluated the cellular location of DDA symbionts. Read More

Effect of sublethal concentrations of ceftriaxone on antibiotic susceptibility of multiple antibiotic-resistant Salmonella strains.

FEMS Microbiol Lett 2019 Jan;366(2)

MOST-USDA Joint Research Center for Food Safety, School of Agriculture & Biology, and State Key Lab of Microbial Metabolism, Shanghai Jiao Tong University, Shanghai 200240, China.

The aim of this study was to determine whether sublethal concentrations of ceftriaxone could alter antibiotic resistance patterns in Salmonella strains. Three multiple antibiotic-resistant Salmonella isolates and the control strain ATCC 13076 were subjected to induction experiments by stepwise increases in sublethal concentrations of ceftriaxone. Sublethal levels of ceftriaxone induced antibiotic resistance but not control Salmonella isolates to ceftriaxone and to other antibiotics. Read More

Regulatory roles of pyruvate-sensing two-component system PyrSR (YpdAB) in Escherichia coli K-12.

FEMS Microbiol Lett 2019 Jan;366(2)

Department of Frontier Bioscience, Hosei University, Kajino-cho 3-7-2, Koganei 184-8584, Tokyo, Japan.

When the rate of production of metabolites in bacteria exceeds the amounts needed for cell growth, excess metabolites are secreted into the extracellular environment. Upon entry into poor nutrient conditions, overflowed exometabolites are reused to continue cell growth and survival. At present, however, the genetic system for utilization of exometabolites is poorly understood even for the best-characterized model prokaryote Escherichia coli. Read More

Salmonella enterica serovar Typhimurium ATCC 14028S is tolerant to plant defenses triggered by the flagellin receptor FLS2.

FEMS Microbiol Lett 2019 Jan 2. Epub 2019 Jan 2.

Department of Bacteriology, University of Wisconsin-Madison, Madison, WI, USA.

Salmonellosis outbreaks associated with sprouted legumes have been a food safety concern for over two decades. Despite evidence that Salmonella enterica triggers biotic plant defense pathways, it has remained unclear how plant defenses impact Salmonella growth on sprouted legumes. We used Medicago truncatula mutants in which the gene for the flagellin receptor FLS2 was disrupted to demonstrate that plant defenses triggered by FLS2 elicitation do not impact the growth of Salmonella enterica serovar Typhimurium ATCC 14028S.

Short exposure to oxygen and sulfide alter nitrification, denitrification, and DNRA activity in seasonally hypoxic estuarine sediments.

FEMS Microbiol Lett 2019 Jan;366(1)

Department of Geology, Lund University, Solvegatan 12, SE-223 62 Lund, Sweden.

Increased organic loading to sediments from eutrophication often results in hypoxia, reduced nitrification and increased production of hydrogen sulfide, altering the balance between nitrogen removal and retention. We examined the effect of short-term exposure to various oxygen and sulfide concentrations on sediment nitrification, denitrification and DNRA from a chronically hypoxic basin in Roskilde Fjord, Denmark. Surprisingly, nitrification rates were highest in the hypoxic and anoxic treatments (about 5 μmol cm-3 d-1) and the high sulfide treatment was not significantly different than the oxic treatment.
