aerobic
genus Pseudomonas divided into five groups based on rRna
Produce a fluorescent pigment
important sewage treatment
animal and plant pathogens
human pathogens cause urinary tract infections, complicate burns and cause food spoilage (psuedomonas aeruginosa)
Vibrio (gamma)
unusual bioluminescen bacteria due to enzyme lukiferase
free-living in water or live in fish
Vibrio cholerae: serious human pathogen causes cholera
Vibrio angullarum causes diseases in fish.

Escherichia
proteus
salmonella
shigella
Pasteurellales (gamma)
pasture ella had a farm full of livestock and rabbits. she became their owner, stopped feeding them, they got small and then stopped moving (nonmotile).
What does Haemophilus influenza cause, same as Neisseria meningiditis?
meningitis because it infects mucous membranes.
Delta Proteobacteria
bdellovibrio
myxobacteria
Desulfovibrionales
(some members are predetory)
use elemental sulfur and oxidized sulfur molecules as electron acceptors in anaerobic respiration
great importance to sulfur cycling in nature
anaerobic habitats rich in decaying materials:sediments, sewage
Bdellovibrio bacteriovorus (delta)
adell is predatory; has long sheathed flagellum (tail) very fast, when she is in the predatory phase and she can also have kids so he has a reproductive phase.
Myxococcalis (myxobacteria) (delta)
Aerobic soil bacteia
chemoheterotrophs
gliding motility (to reach nutrients in soil)
life cycle involves fruiting bodies when no nutrients available (dormant at times in same situation)
May be predatory
What are the epsilon proteobacteria?
Helicobacter pylori
campilobacter jejuni
Campilobacter jejuni (microaerophilic)
causees gastroenteritis (common cause of food posoning) and septicemia in humans
