Editor’s Selections: Infection by injection, Arctic bacterial genes make for a safe vaccine, and five ways that honey kills bacteria

Editor's Selections 17 Comments
By Vincent Racaniello

Vincent RacanielloVincent Racaniello selects several notable posts each week from molecular and cellular biology and virology. He blogs at virology blog.

  • Bacteria produce little needles, also known as type III secretion systems, for injecting toxins into cells. These systems are not required for survival of opportunistic bacteria such as P. aeruginosa, but their absence reduces virulence.
  • Developing vaccines to protect against lethal bacterial pathogens requires a balance between a robust immune response and absence of disease. Introduction of genes into pathogens from Arctic bacteria leads to death at physiological temperatures and a safe and efficacious vaccine.
  • Honey has been known since ancient times to have antibacterial activity. The reason why is a combination of five factors: hydrogen peroxide, sugar, methylglyoxal, bee defensin 1, and acid.

I’ll be back next Friday with more selections.
