Stenotrophomonas maltophilia AHL-Degrading Strains Isolated from Marine Invertebrate Microbiota Attenuate the Virulence of Pectobacterium carotovorum and Vibrio coralliilyticus.

Mar Biotechnol (NY) 2019 Feb 14. Epub 2019 Feb 14.

Department of Microbiology, Faculty of Pharmacy, University of Granada, 18071, Granada, Spain.

Many Gram-negative aquacultural and agricultural pathogens control virulence factor expression through a quorum-sensing (QS) mechanism involving the production of N-acylhomoserine (AHL) signalling molecules. Thus, the interruption of QS systems by the enzymatic degradation of signalling molecules, known as quorum quenching (QQ), has been proposed as a novel strategy to combat these infections. Given that the symbiotic bacteria of marine invertebrates are considered to be an important source of new bioactive molecules, this study explores the presence of AHL-degrading bacteria among 827 strains previously isolated from the microbiota of anemones and holothurians.

Vibrio variations on a type three theme.

Curr Opin Microbiol 2019 Jan 31;47:66-73. Epub 2019 Jan 31.

Department of Microbiology and Immunology, University of Rochester School of Medicine and Dentistry, Rochester, NY 14642, United States. Electronic address:

Mounting evidence suggests that Type 3 Secretion Systems (T3SS) are widespread among Vibrio species, and are present in strains isolated from diverse sources such as human clinical infections, environmental reservoirs, and diseased marine life. Experiments evaluating Vibrio parahaemolyticus and Vibrio cholerae T3SS mediated virulence suggest that Vibrio T3SS pathogenicity islands have a tripartite composition. A conserved 'core' region encodes functions essential for colonization and disease in vivo, including modulation of innate immune signaling pathways and actin dynamics, whereas regions flanking core sequences are variable among strains and encode effector proteins performing a diverse array of activities.

Using the wax moth larva infection model to detect emerging bacterial pathogens.

PeerJ 2019 4;6:e6150. Epub 2019 Jan 4.

European Centre for Environment and Human Health, University of Exeter, Penryn, UK.

Climate change, changing farming practices, social and demographic changes and rising levels of antibiotic resistance are likely to lead to future increases in opportunistic bacterial infections that are more difficult to treat. Uncovering the prevalence and identity of pathogenic bacteria in the environment is key to assessing transmission risks. We describe the first use of the Wax moth larva , a well-established model for the mammalian innate immune system, to selectively enrich and characterize pathogens from coastal environments in the South West of the UK.

Infection by invasive parasites increases susceptibility of native hosts to secondary infection via modulation of cellular immunity.

J Anim Ecol 2018 Dec 13. Epub 2018 Dec 13.

AWI Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research, Coastal Ecology, Waddensea Station Sylt, List, Germany.

Parasite spillover from invasive aliens to native species increases the risk of disease emergence within native biota-either by direct harm to the new host or by indirect effects like increased risks of secondary infection. One example for such a detrimental effect is the parasitic copepod Mytilicola intestinalis that infected blue mussels Mytilus edulis after being introduced into the North Sea in the early 20th century. Since 1949, the parasite was blamed for multiple mass mortalities of infested blue mussels but evidence for a direct causal involvement of M. Read More

The structure of temperate phage-bacteria infection networks changes with the phylogenetic distance of the host bacteria.

Biol Lett 2018 Nov 14;14(11). Epub 2018 Nov 14.

GEOMAR Helmholtz Centre for Ocean Research Kiel, 24105 Kiel, Germany.

With their ability to integrate into the bacterial chromosome and thereby transfer virulence or drug-resistance genes across bacterial species, temperate phage play a key role in bacterial evolution. Thus, it is paramount to understand who infects whom to be able to predict the movement of DNA across the prokaryotic world and ultimately the emergence of novel (drug-resistant) pathogens. We empirically investigated lytic infection patterns among spp. Read More

Structure and oligomerization of the periplasmic domain of GspL from the type II secretion system of Pseudomonas aeruginosa.

Sci Rep 2018 Nov 13;8(1):16760. Epub 2018 Nov 13.

Unit for Structural Biology, Department of Biochemistry and Microbiology, Ghent University, 9052, Ghent (Zwijnaarde), Belgium.

The ability of bacteria to infect a host relies in part on the secretion of molecular virulence factors across the cell envelope. Pseudomonas aeruginosa, a ubiquitous environmental bacterium causing opportunistic infections in humans, employs the type II secretion system (T2SS) to transport effector proteins across its cellular envelope as part of a diverse array of virulence strategies. General secretory pathway protein L (GspL) is an essential inner-membrane component of the T2SS apparatus, and is thought to facilitate transduction of the energy from ATP hydrolysis in the cytoplasm to the periplasmic components of the system.

Therapeutic Potential of a New Jumbo Phage That Infects , a Widespread Coral Pathogen.

Front Microbiol 2018 24;9:2501. Epub 2018 Oct 24.

Sorbonne Universités UPMC Paris 06, CNRS, UMR7144 Adaptation et Diversité en Milieu Marin, Station Biologique de Roscoff, Roscoff, France.

Biological control using bacteriophages is a promising approach for mitigating the devastating effects of coral diseases. Several phages that infect , a widespread coral pathogen, have been isolated, suggesting that this bacterium is permissive to viral infection and is, therefore, a suitable candidate for treatment by phage therapy. In this study, we combined functional and genomic approaches to evaluate the therapeutic potential of BONAISHI, a novel phage, which was isolated from the coral reef in Van Phong Bay (Vietnam).

Water-soluble cranberry extract inhibits Vibrio cholerae biofilm formation possibly through modulating the second messenger 3', 5' - Cyclic diguanylate level.

PLoS One 2018 7;13(11):e0207056. Epub 2018 Nov 7.

Department of Biological Sciences, Clemson University, Clemson, South Carolina, United States of America.

Quorum sensing (QS) and nucleotide-based second messengers are vital signaling systems that regulate bacterial physiology in response to changing environments. Disrupting bacterial signal transduction is a promising direction to combat infectious diseases, and QS and the second messengers are undoubtedly potential targets. In Vibrio cholerae, both QS and the second messenger 3', 5'-cyclic diguanylate (c-di-GMP) play a central role in controlling motility, motile-to-sessile life transition, and virulence. Read More

Occurrence and significance of pathogenicity and fitness islands in environmental vibrios.

AMB Express 2018 Oct 30;8(1):177. Epub 2018 Oct 30.

Department of Biological Sciences, University of South Carolina, 715 Sumter St, Room 401, Columbia, SC, 29208, USA.

Pathogenicity islands (PAIs) are large genomic regions that contain virulence genes, which aid pathogens in establishing infections. While PAIs in clinical strains (strains isolated from a human infection) are well-studied, less is known about the occurrence of PAIs in strains isolated from the environment. In this study we describe three PAIs found in environmental Vibrio vulnificus and Vibrio parahaemolyticus strains, as well as a genomic fitness island found in a Vibrio diabolicus strain. Read More

Bacterial Biofilm Material Properties Enable Removal and Transfer by Capillary Peeling.

Adv Mater 2018 Nov 8;30(46):e1804153. Epub 2018 Oct 8.

Department of Mechanical and Aerospace Engineering, Princeton University, D328 E-Quad, Olden St., Princeton, NJ, 08544, USA.

Biofilms, surface-attached communities of bacterial cells, are a concern in health and in industrial operations because of persistent infections, clogging of flows, and surface fouling. Extracellular matrices provide mechanical protection to biofilm-dwelling cells as well as protection from chemical insults, including antibiotics. Understanding how biofilm material properties arise from constituent matrix components and how these properties change in different environments is crucial for designing biofilm removal strategies.

The influence of three antibiotics on the growth, intestinal enzyme activities, and immune response of the juvenile sea cucumber Apostichopus japonicus selenka.

Fish Shellfish Immunol 2019 Jan 9;84:434-440. Epub 2018 Oct 9.

Ocean School, Yantai University, Yantai, PR China.

The global abuse and misuse of antibiotics in the treatment and prevention of bacterial infections has resulted in the ubiquitous existence of these drugs in aquatic environments, which causes frequent antimicrobial resistance and pollution in ecosystems. However, the chronic effects of antimicrobial agents on aquatic animal growth and health have not been fully evaluated. In the present study, three typical antibiotics (tetracycline, erythromycin, and norfloxacin) were administered orally to juvenile sea cucumbers Apostichopus japonicus for 45 days, to mimic the long-term use of antibiotics.
