NewsResearchers take step towards creating Salmonella vaccine
A study of a new method to deliver a Salmonella vaccine found that when tested with real-world strains of Salmonella, the vaccine created antibodies against this microbe in the mice – which equips the animals with a defense mechanism against the pathogen.

NewsJumbo phages deploying secret handshakes could usher in new antibiotics
Jumbo phages create a restricted space inside bacteria where they can copy their DNA while surrounded by a protective shield. A new study reveals that the shield works via a set of ’secret handshakes’, allowing only a specific set of useful proteins to pass through.
