Bacteria firing powerful spikes

This week we will talk about one of my favourite bacterial devices. It is the bacterial killing machine, the type 6 secretion system, that I explained in detail in my very first post Bacteria killing each other. If you don’t remember well what is was, it is worth going back to refresh your memory, as we’re now looking closer into this fascinating nanomachine. This post is based on a journal article which was just published and which I would like to share with you here. It was also the longest and most tedious chapter of my thesis, so I have … Continue reading Bacteria firing powerful spikes

Bacteria changing blood types

In this article I want to talk about a mechanism that, when I read about it, completely fascinated me.

But as always, let’s start with the basics. We have four different blood types based on the sugars that are on the surface of our blood cells (I am not going to talk about rhesus factors here). These sugar blocks are generally called antigens, because they are recognised by … Continue reading Bacteria changing blood types
