Bacteria can be major problems for human health. One of the reasons for that is because they have the ability to form biofilms. What is a biofilm you ask? I am glad you’re here. Bacterial biofilms are defined as a … Continue reading Bacteria building houses
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
As you might well be aware of by now, our body is full of bacteria. All those little bugs that usually live there are together called the human microbiota. They are the reason why you are never truly alone 😉 Basically on all our surfaces, like the skin, in our nose, mouth, in our urogenital or gastrointestinal tract live bacteria. The skin and the mucosa in our nose and mouth are like a barrier for bacteria to keep them out of our body. This means that our internal organs are basically sterile, no bacterium there to be found… Or are … Continue reading How bacteria get (too) attached
How do bacteria find food? It is an important question as everything and also bacteria need to intake food/nutrients to survive and grow. Think about how you get food. First of all you realise that you are hungry, then you need to know where your next food source is, which can be either your fridge or the nearest take away, and then you move towards it. Bacteria do it very similarly. Interestingly, most bacteria can move or swim towards a nutrient as soon as they are hungry and they know where to find food. This process of bacterial movement according … Continue reading Towards the goodies!
What would be a microbiology blog without discussing antimicrobial resistances or AMRs? Everybody has probably heard about them in recent news, but what exactly are they and what is the problem with them? So far I have only written about … Continue reading About antimicrobial resistances and their problems
I am a big fan of all the research about how bacteria interact with each other and also with us. This is why my first article in this blog was about how bacteria kill their enemies. However, this article is … Continue reading How bacteria feed each other in times of hunger
While the last article was about the project I studied in the past, this one will be about the project I am currently working on. Generally, it is about how bacteria sense the presence of iron in an environment where there is only little iron present. Okay, let’s start from the beginning. One reason why I am so fascinated with bacteria, is because they can basically survive in all kinds of different environments. However, these changing environments require proper preparations. Just as you would put on some layers of warm clothes in winter when you go outside, they need to adapt to … Continue reading Bring in the iron!
Most people have only ever heard of those bad bacteria that make us sick and give us diarrhoea or pneumonia. However, few people actually know that those little bugs are all around us. They live in every corner of our body, they can be basically found everywhere in nature, be it in the forest, in the sea or in volcanoes. They are also amazing flatmates, sitting on your toilet, in the kitchen or in your bed. Now for example, imagine an environment within our body which is full of nutrients and metals, like our gut. A real paradise for bacteria … Continue reading Bacteria killing each other
