Chlamydia pneumoniae,

 a bacterium that causes respiratory infections, is probably
under-diagnosed. There is also interest in its possible role in the aetiology of
coronary heart disease.

Sorry Jim Bob, I Wrote the wrong word!

Chlamydia Antibodies

I hate to disappointed you but antibodies are proteins produced by B cells , Karen.

ALL fixed was reading a test and wrote the test and not the bacteria, thanks for calling it to my attention!

Helicobacter pylori is a spiral shaped bacterium. It lives on the gastric epithelium under the mucus layer of the stomach and duodenum. The bacterium is thought to damage this mucus layer, which is the stomach and duodenum's natural protection from gastric acids. Local inflammation caused by the bacterial infection and exposure to these acids can damage the lining of the stomach and duodenum, eventually leading to ulceration and possibly gastric cancer.

Had this bug and diagnosed it myself to my GP having watched a programme about its discovery

Lactobacillus acidophilus

Our friendly bacteria, living in most of you right now.We can classify it as a probiotic :)

Bdellovibrio - the world's fastest swimmers - capable of 60 body lengths per second, which is faster even than a jet.

Fred
OK, I'm not saying what this bacterium does but I'm perfectly certain that there a re a whole host of bacteria that live in the body which nobody has ever noticed, studied or named.
I propose to call the most Northerly of these "Fred".
Obviously, if someone names that one, then the title Fred will have to go to the next unnamed bug South.
For those who want a more conventional answer, how about Propionibacterium acnes?

Conan the bacterium

One of the newly discovered bacteria types is a relative of Deinococcus radiodurans, one of the hardiest organisms alive.


D. radiodurans is a so-called extremophile because it thrives in extreme environments that would kill most organisms, such as radioactive waste dumps and hot springs. While a radiation dose of 10 grays (Gy) would kill a human, D. radiodurans can take up to 5,000 Gy with no visible effect. It can survive heat, cold, vacuum, and acid. It is so resilient scientists nicknamed it "Conan the Bacterium," after the fictional barbarian warrior.

It's unclear, however, whether the new D. radiodurans relative is likewise resistant to radiation, said David Relman, a microbiologist and immunologist at Stanford University and principal investigator in the study.

"This thing could be a totally different and novel bacteria, but only because its closest relative is famous for being incredibly radioresistant would we even think this one might be as well," Relman told LiveScience.

Relman said the next step is to observe the stomachs of volunteers over time to determine whether the newly identified stomach bacteria actually live there or whether they're just passing through.

"It could be possible that we have a continuous flow of organisms through the stomach and that very few of these are staying put," Relman said.
