    Health hazards to wild birds and risk factors associated with anthropogenic food provisioning.
    Philos Trans R Soc Lond B Biol Sci 2018 May;373(1745)
    Institute of Zoology, Zoological Society of London, Regent's Park, London NW1 4RY, UK.
    Provision of supplementary food for wild birds at garden feeding stations is a common, large-scale and year-round practice in multiple countries including Great Britain (GB). While these additional dietary resources can benefit wildlife, there is a concomitant risk of disease transmission, particularly when birds repeatedly congregate in the same place at high densities and through interactions of species that would not normally associate in close proximity. Citizen science schemes recording garden birds are popular and can integrate disease surveillance with population monitoring, offering a unique opportunity to explore inter-relationships between supplementary feeding, disease epidemiology and population dynamics.

    MBio 2018 Mar 6;9(2). Epub 2018 Mar 6.
    Institute for Microbiology and Infection, School of Immunology and Immunotherapy, Institute for Biomedical Research, University of Birmingham, Birmingham, United Kingdom
    Antibodies acquired after vaccination or natural infection with Gram-negative bacteria, such as invasiveserovar Typhimurium, can protect against disease. Immunization with naturally shed outer membrane vesicles from Gram-negative bacteria is being studied for its potential to protect against many infections, since antigens within vesicles maintain their natural conformation and orientation. Shedding can be enhanced through genetic modification, and the resulting particles, generalized modules for membrane antigens (GMMA), not only offer potential as vaccines but also can facilitate the study of B-cell responses to bacterial antigens.

    Here, we hypothesized that the microbial gut flora of animals/pests living in polluted environments, produce substances to thwart bacterial infections. The overall aim of this study was to source microbes inhabiting unusual environmental niches for potential antimicrobial activity. Two cockroach species, Gromphadorhina portentosa (Madagascar) and Blaptica dubia (Dubia) were selected. Read More
