When the virus attacks again, the bacterium quickly makes an RNA copy from the DNA archive and arms a secret weapon - a protein called Cas9.
When it finds a 100% perfect match, it is activated and cuts out the virus DNA, making it useless, protecting the bacterium against the attack.
And so Clostridium difficile is the bacterium there that causes a terrible, terrible infection in the colon that can sometimes result in the entire colon needing to be removed.

After infection with the bacterium Yersinia Pestis, lymph nodes swell and sometimes burst; victims often get high fevers and vomit blood; gangrene can cause extremities and facial features to turn black with necrosis, hence "the Black Death."

And so by our interest in the lab to find new molecules that could have a role in the bacterium Streptococcus pargenes, we came across a very neat mechanism that allows us to really recognize the virus that infects the bacterium in a very, very specific manner at the level of the genome of the virus.

However, an analysis of DNA from victims in northern and southern Europe published in 2010 and 2011 indicates that the pathogen responsible was the Yersinia pestis bacterium, causing several forms of the plague.

He injected a bacterium commonly found in soil into mice to see what affect this would have on them.

Imagine a bacterium as a very complex machine with thousands of complex processes going on that keep it alive and active.

And they, unlike the neutrophils, don't die once they've killed a bacterium.

Pluto, a bacterium.
Jupiter would be the size of a dust mite on that page, and Pluto a bacterium.
