Are There Bacteria in Your Brain?
A surprising new result catches the attention of the neuroscience community.

Rosalinda Roberts had gotten used to seeing weird shapes in the brain. Over three decades of looking at brain tissue under an electron microscope, she’d regularly come across “unknown objects”—specks and blobs in her images that weren’t supposed to be there, and didn’t seem to relate to the synapses and structure that she was studying. “I’d just say, ‘well I’m not going to pay attention to that’ ” she explains. That’s all changed now.
Finding bacteria in the brain is usually very bad news. The brain is protected from the bacterial menagerie of the body by the blood-brain barrier, and is considered a sterile organ. When its borders are breached, things like encephalitis and meningitis can result. Which made it all the more surprising when Roberts, along with Charlene Farmer and Courtney Walker, realized that the unknown objects in their slides were bacteria.

Many of them were caught mid-stride, entering neurons or penetrating axons. Others were in the process of dividing. They were picky, too, strongly preferring some regions of the brain over others. The surrounding brain tissue showed no signs of inflammation. If the bacteria were in the brain while the individual was alive, they were not pathogenic.

If it’s confirmed—contamination has not been definitively ruled out—the work opens up new avenues of research into the microbiome and disease. The group presented their results this month at the annual Society for Neuroscience meeting this month, and Nautilus caught up with Roberts last week.

So .... Pretty much every body part we thought was sterile isn't!?

I'm fascinated by the idea they're not causing inflammation up there. What if they are even beneficial?

Increasingly it seems we are not so much an organism as an eco system and I honestly think it will be very hard for a lot of people to accept that a functioning human is at least partly bug.

It is crazy to think that anything on this planet is sterile.
But then all diseases which we at the moment say it is all in your mind aren't possible anymore because pathogens/bugs are the real cause.
This includes autism and all "psychological diseases".
I guess they are all caused by (not yet found) pathogens.
