  • 'Designer' Bacteria May Lead to Better Vaccines
    Researchers at the University of Texas at Austin have developed a menu of 61 new strains of genetically engineered bacteria that may improve the efficacy of vaccines for diseases such as flu, pertussis, cholera and HPV. The strains of E. coli, which were described in a ...More

  • Gut Bacteria's Collection of Genomes is Unique, Remains Stable Over Time
    We all have E. coli bacteria in our gut but each of us carries a version that is genetically slightly different. The same can be said of most gut microbes: our own gut metagenome, that is the sum of all the genomes of all our gut microbes, appears to be really specific to ...More

  • Bacteria Hijack Host Cell Process, Create Their Own Food Supply to Become Infectious
    Bacteria that cause the tick-borne disease anaplasmosis in humans create their own food supply by hijacking a process in host cells that normally should help kill the pathogenic bugs, scientists have found. This bacterium, Anaplasma phagocytophilum (Ap), secretes a protein ...More
