Ten proteobacteria:
- Neisseria gonorrhoeae
- Campylobacter jejuni
- Pelagibacter ubique
- Bdellovibrio bacteriovorus
- Helicobacter pylori
- Thiomargarita namibiensis
- Legionella longbeachae
- Vibrio vulnificus
- Haemophilus influenzae
- Caulobacter crescentus
astrablue wanted to see Vibrio vulnificus mentioned in a list, because she has a thing for pathogens. This is, incidentally, the second member of genus Vibrio to appear in one of my lists; Vibrio fischeri made an appearance in a list of species of bacteria that have mutualistic or commensalistic relationships with humans or animals. Not that I need to remind any of you about that particularly scintillating list.
I was going to include a little paragraph here explaining what proteobacteria are, but to hell with it. Just go read the Wikipedia article.
