In the last article, we concluded that our gut microbiome helps us with three main functions. They help us digesting foods, protect us from pathogens and enhance our immune system. To understand how exactly the gut microbiome helps the immune … Continue reading The gut microbiome protecting its host
You probably have been following me on my blog or on social media for a while now. And maybe you remember reading my words “be nice to your bacteria” somewhere. And you probably also thought “what does she mean by … Continue reading What is the gut microbiome and why should I care?
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
All living cells require iron to live, this includes bacteria and human cells, because iron has essential functions in the cellular metabolism. The problem is, that free iron is actually toxic, so that each organism needs to make sure iron … Continue reading What the presence of iron tells a bacterium about its location
Throughout summer I had a not so nice encounter with the least favourite of all doctors – the dentist. While she was tampering with my teeth, I realised I barely know anything about those bacteria that cause this nasty disease … Continue reading What bacteria do to our teeth
This week will be all about another one of my favourite killing devices bacteria invented. This one is called CDI for contact-dependent growth inhibition, which means bacteria kill (inhibit the growth of) other bacteria when they are close to each … Continue reading Death on a stick
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
