Accumulating evidence demonstrates that viruses are the most abundant biological entities on the planet. They outnumber bacteria by approximately 10 to 1 and there are an estimated >1030 tailed bacteriophages globally! The result is an obvious selective pressure for bacteria to acquire resistance to phage attack and for phage to acquire counter defence mechanisms. Indeed, many mechanisms of phage resistance are known, ranging from bacterial cell surface alterations, through restriction and modification, to abortive infection
Our research goal is to understand the interactions between mobile genetic elements, such as bacteriophages and plasmids, and their bacterial hosts. Our main interest is in phage resistance mechanisms.
