prokaryotic diversity genus charts Flashcards
what are the 5 classes of proteobacteria
alphaproteobacteria
betaproteobacteria
gammaproteobacteria
deltaproteobacteria
epsilonproteobacteria
list some alphaproteobacteria
agrobacterium
bartonella
brucella
caulobacter
ehrlichia
hyphomicrobium
methylocystis
rhizobium
rickettsia
unique characteristics of agrobacterium
plant pathogen, one species, a. tumefaciens, causes tumors in plants
unique characteristics of bartonella
facultative intracellular bacteria, transmitted by lice, fleas, cause trench fever and cat scratch disease inhumans
unique characteristics of brucella
facultative intracellular bacteria, transmitted by contaminated milk from infected cows, cause brucellosis in cattle and humans
unique characteristics of caulobacter
Used in studies on cellular adaptation and differentiation because of its peculiar life cycle (during cell division, forms “swarm” cells and “stalked” cells)
unique characteristics of ehrlichia
Obligatory intracellular bacteria; can be transported from cell to cell; transmitted by ticks; cause ehrlichiosis (destruction of white blood cells and inflammation) in humans and dogs
unique characteristics of hyphomicrobium
Similar to Caulobacter
unique characteristics of methylocystis
Nitrogen-fixing aerobic bacteria
unique characteristics of Rhizobium
Nitrogen-fixing bacteria that live in soil and form symbiotic relationship with roots of legumes (e.g., clover, alfalfa, and beans)
unique characteristics of Rickettsia
Obligate intracellular bacteria; transmitted by ticks; may cause Rocky Mountain spotted fever and typhus, cannot synthesize their own ATP
list betaproteobacteria
bordetella
burkholderia
leptothrix
neisseria
thiobacillus
unique characteristics of bordetella
Aerobic, very fastidious; B. pertussis causes pertussis (whooping cough)
unique characteristics of Burkholderia
Aerobic, aquatic, cause diseases in horses and humans (especially patients with cystic fibrosis); agents of nosocomial infections
unique characteristics of leptothrix
Aquatic; oxidize iron and manganese; can live in wastewater treatment plants and clog pipes
unique characteristics of Neisseria
Require moisture and high concentration of carbon dioxide; oxidase positive, grow on chocolate agar; pathogenic species cause gonorrhea and meningitis
