Document Summary
Vibrio, rickettsias, and spirilla: vibrio and photobacterium, Vibrio cholera is human pathogen which causes cholera, Disease is usually associated with poor water sanitation. Also a number of vibrio strains that aren"t pathogenic: some of these organism are bioluminescent and associated with fish. Bioluminescence requires the luciferase enzyme, which is produced as a result of gene expression at high population concentration: rickettsia: Mitochondria evolve from organisms that probably had similar relationships with their host cell, Organism that are classified based on their spiral cell shape but they"re very phylogenetically diverse grouping, Budding and stalked bacteria and gliding myxobacteria: budding and stalked: Grouped based together on their cell type or division. Unequal cell division in which the division occurs in one region of the cell where a bud forms. Most are alpha but some beta and gammas. Will often have extrusions from the cell, Sometimes have holdfast that help keeping the organism attached to the solid surface.
