| Prokaryotes do/do not reproduce sexually | DO NOT |
| what are the 5 classes in Gram NEG. phyla | Proteobacteria; Spirochete; CFB group; Planctomycetes; Phototropic bacteria |
| Alphaproteobacteria are olgiotrophs meaning? | LOW nutrient enviorments; intracellular; NEED host |
| Rickettsia | rocky mountain fever + typhus fever |
| Chlamydia | lymphogranuloma venereum |
| Betatrophic are eutrophic meaning? | they NEED nutrients |
| Bordetella | whooping cough + kennel cough |
| Neisseria gonorrhea | gonorrhea STD |
| Neisseria meningitides | bacterial meningitis |
| Gammaproteobacteria | 3 genus? |
| Pseudomonas aeruginosa | infection wounds, respiratory & urinary tract |
| Pasteurella haemolytica | severe pneumonia in animals |
| Haemophilus influenzia | upper & lower respiratory infections |
| Vibrio spp | alkaline enviorments (ocean ports & lagoons) |
| Vibrio cholera | cholera due to water contamination |
| Legionella pneumophilia | Legionnaires disease + contamination of water |
| enterobacter family includes? | E.coli & salmonella spp |
| Coliforms | complete fermentation of lactose |
| Non-coliforms | incomplete or no fermentation of lactose |
| E.coli | mutualistic + shinga toxin |
| Deltaproteobacteria | small; sulfate reducing bacteria |
| Desulfovibrio orale | periodontal disease |
| Bdellovibrio | aerobes; motile parasitic that infects other bacteria |
| Myxobacteria | soil dweling slime bacteria |
| Epsilonproteobacteria | smallest class, micriaerophilic |
| Campylobacter spp. | food poisoning |
| Helicobacter spp. | causes ulcers & stomach cancer |
| 2) Spirochetes | thin + extremely hard to stain & culture + axial filament similar to flagella |
| Treponema pallidum | syphilis |
| Borrelia burgodorferi | Lyme disease |
| CFB group stands for what? | Cytophaga, Fusobacterium, Bacteroides |
| Cytophaga spp. | gliding system for motility |
| Fusobacteria spp. | inhabit mouth and can cause various oral diseases |
| Bacteroides spp. | 30% of gut microbiome; lower levels correlated with obesity |
| Planctomycetes | aquatic environments: fresh, salt, and brackish; Reproduce via budding not binary fission |
| Sessile cells | immobile w/ holdfast appendage |
| Swarmer cells | motile, unable to reproduce |
| Phototrophic Bacteria | Grouped based on function; Utilize sunlight as main source of energy; photosynthesis |
| Oxygenic | produce O2 |
| Anoxygenic | DO NOT produce O2 |
| Cyanobacteria | highly adaptable and diverse; chlorophyll; uses as biosorbents and human nutrition |
| Microsystis spp. | toxic algal blooms |
| Anoxygenic photosynthesizers | Purple sulfur bacteria - Purple non-sulfur bacteria – use only hydrogen Green sulfur bacteria – oxidize sulfide Green non-sulfur bacteria – oxidize non-sulfide substrates |
