The bacterial armoury

In many of my previous posts I talked about how bacteria fight each other using one of their many killing devices (for example here or here). I also described a few strategies of how bacteria deliver toxins into competing bacteria (like here or here). And I always say that these toxins are the ones that finally kill the prey bacterium. So the questions I want to answer this week are: what does this toxin do once it reached the prey bacterium? How does a toxin kill a bacterium? And why is the toxin-producing bacterium not killed by the toxin? Please … Continue reading The bacterial armoury

Tiny Biological Needles: How Some Bacteria Are Able to Infect Their Targets

Hi there! My name is Danny Ward and I am a PhD student at the John Innes Centre and the University of East Anglia in Norwich, England. Today, I’m going to be telling you a little about what research I am working on, any why it is important. As the title suggests, I work on tiny biological needles. Tiny biological needles? Yes, you did indeed read that correctly! For many, we know that certain bacteria can cause disease but exactly how they are able to infect their targets often remains a mystery. One such system, responsible for promoting bacterial infection, … Continue reading Tiny Biological Needles: How Some Bacteria Are Able to Infect Their Targets
