==Sections/Classes==
The proteobacteria are divided into five sections, referred to by the [[Greek letters]] alpha through epsilon, again based on rRNA sequences. These are often treated as classes. Note the Gamma Proteobacteria are [[paraphyly|paraphyletic]] to the Beta Proteobacteria. Not All Are
===Alphaproteobacteria===
Line 118 ⟶ 108:
===Gammaproteobacteria===
[[
The Gammaproteobacteria comprise several medically and scientifically important groups of bacteria, such as the [[Enterobacteriaceae]], [[Vibrionaceae]] and [[Pseudomonadaceae]]. An exceeding number of important pathogens belongs to this class, e.g. ''[[Salmonella]]'' ([[enteritis]] and [[typhoid fever]]), ''[[Yersinia]]'' (plague), ''[[Vibrio]]'' (cholera), ''[[Pseudomonas aeruginosa]]'' (lung infections in hospitalised or [[cystic fibrosis]] patients).
===Deltaproteobacteria===
The Deltaproteobacteria comprise a branch of predominantly aerobic genera, the fruiting-body-forming [[myxobacteria]], and a branch of strictly anaerobic genera, which contains most of the known [[sulfate-reducing bacteria|sulfate-]] (''Desulfovibrio'', ''Desulfobacter'', ''Desulfococcus'', ''Desulfonema'', etc.) and [[sulfur-reducing bacteria]] (e.g. ''Desulfuromonas'') alongside several other anaerobic bacteria with different physiology (e.g. ferric iron-reducing ''[[Geobacter]]'' and syntrophic ''Pelobacter'' and ''Syntrophus'' species).
===Epsilonproteobacteria===
[[
The Epsilonproteobacteria consist of only a few genera, mainly the curved to spirilloid ''[[Wolinella]]'', ''[[Helicobacter]]'', and ''[[Campylobacter]]''. They all inhabit the digestive tract of animals and humans and serve as [[symbiosis|symbionts]] (''Wolinella'' in [[cattle|cows]]) or [[pathogen]]s (''Helicobacter'' in the stomach, ''Campylobacter'' in the duodenum).
