4 Bacteria - Eubacteria Ancient fossils 3.5 billion years b.p.
Archetype for prokaryotic organisms Phototrophs Chemoautotrophs Heterotrophs Saprobes Parasites (bacteria benefit, host harmed) Commensals (bacteria benefit, host unharmed) Mutualists (bacteria and host both benefit) Unicellular, colonial, filamentous Bacillus, coccus, spirillum

6 to Domains Archaea and Eukarya
Domain Prokarya Kingdom Bacteria Proteobacteria Chlamydias Spirochetes Gram Positive Cyanobacteria to Domains Archaea and Eukarya Universal Ancestor

7 Domain Prokarya Kingdom Bacteria  Proteobacteria Gram-negative
photoauto-, chemoauto-, hetero-trophs symbionts, parasites Rhizobium-legumes: N2 fixation Agrobacterium-host: Recombinant DNA Rickettsias: Rocky Mountain Fever likely source of mitochondrion by endosymbiosis Universal Ancestor

8 Domain Prokarya Kingdom Bacteria  Proteobacteria Gram-negative
photoauto-, chemoauto-, hetero-trophs nutritionally diverse Nitrosomonas in soil: NH NO2- ammonium nitrite Universal Ancestor

9 Domain Prokarya Kingdom Bacteria  Proteobacteria Gram-negative
photoauto-, chemoauto-, hetero-trophs Photosynthetic: Chromatium CO2 + H2S CH2O + S(solid) Heterotrophic: Legionella-Legionnaires’ disease Enterics: Escherichia coli in your intestine Salmonella food poisoning Vibrio cholerae cholera Universal Ancestor

10 Domain Prokarya Kingdom Bacteria  Proteobacteria Gram-negative
photoauto-, chemoauto-, hetero-trophs Myxobacteria: slime secretion, aggregation, spores Bdellovibrios: rapid locomotion 100m/sec penetrate prey bacteria 100 rps Universal Ancestor

11 Domain Prokarya Kingdom Bacteria  Proteobacteria Gram-negative
photoauto-, chemoauto-, hetero-trophs Helicobacter pylori: human stomach ulcers Universal Ancestor

12 Domain Prokarya Kingdom Bacteria Proteobacteria Chlamydias
Gram-negative parasites inside animal cells Chlamydia trachomatis: blindness Non-gonococcal urethritis: common STD (most-common in USA!) Universal Ancestor

13 Domain Prokarya Kingdom Bacteria Proteobacteria Chlamydias Spirochetes
Helical heterotrophs to 0.25 mm long but very thin! Rotational bacterial filament Free-living and pathogens: Treponema pallidum = syphilis Borrelia burgdorferi = Lyme disease Universal Ancestor

14 Gram Positive: very diverse
Domain Prokarya Kingdom Bacteria Proteobacteria Chlamydias Spirochetes Gram Positive: very diverse Actinomycetes: branched chains tuberculosis, leprosy Soil: Streptomyces antibiotics Solitary: Bacillus, Clostridium anthrax, botulism Staphylococcus: clusters Streptococcus: chains “hospital diseases” Mycoplasmas 0.1m walking pneumonia Universal Ancestor

15 Domain Prokarya Kingdom Bacteria Proteobacteria Chlamydias Spirochetes
Gram Positive Cyanobacteria likely source of chloroplast by endosymbiosis unicell, colony, filament photoautotrophs: CO2 + H2O O2 + CH2O heterocysts: N2 fixation N2 + H+ + ATP NH4+ Universal Ancestor
