Group of proteobacteria from which mitochondra and chloroplasts are thought to be derived
alphaproteobacteria
An organism that requires high carbon dioxide levels
capnophile
Genus of facultative anaerobes that live in human intestines, typically without causing disease- however there are some strains that are pathogenic such as O157:H7
Escherichia coli
This genus of bacteria are microaerophilic and are associated with chickens, can be transferred to humans in undercooked meat causing severe enteritis (diarrhea)
Campylobacter
Genus of Gram positive organism that causes tuberculosis
Mycobacterium
genus of nitrogen fixing bacteria, live in plant roots to help plant get nitrogen
Rhizobium
An organism that must be inside a host cell to reproduce
Obligate intracellular parasite
Genus that produces blue and yellow pigments which sometimes appear green in pus draining from wounds or in culture, pathogen of particular concern for surgical wounds or burns or chronic ulcers
Pseudomonas
This microaerophilic genus of bacteria have been associated with causing stomach ulcers and even stomach cancer
Helicobacter pylori
Low G+C gram positive genus that may produce hemolysins
Streptococcus
Term to describe that the bacterium requires high level of nutrients
eutroph or eutrophic
Relationship where one organism benefits and one is unaffected
commensalism
Serratia marcescens
This spirochete genus of nonproteobacteria is the etiology (cause) of syphilis
Treponema pallidum
Approximately how long ago did bacteria emerge on Earth?
3.5-4.0 billion years ago!!!
Genus of bacteria that causes whooping cough (gold star if you know species too!)
Bordetella pertussis
Term to describe an organism with complex nutritional requirements that may be difficult to provide in a laboratory setting
fastidious
This class of proteobacteria are the sulfur reducing bacteria that may form spores
deltaproteobacteria
This photosynthetic bacterium is anoxygenic, meaning that it performs photosynthesis without producing oxygen.
(Such organisms use reduced electron donors like hydrogen sulfide, hydrogen gas, or ferrous iron, resulting in byproducts like elemental sulfur instead of oxygen.)
Chlorobium
What genus is considered a polyextremophile and can even withstand radiation!?
Deinococcus radiodurans
Genus that causes gonorrhea and some forms of meningitis
Neisseria
Term to describe that an organism requires oxygen
aerobic
This genus of bacteria is a curved rod that reduces sulfur and has been used to clean up radioactive waste
This genus of oxygenic photosynthesizers are a type of cyanobacteria, these do not cause disease but can create "blooms" when excess fertilizer runs off into water systems
Microcystis
What genu of Archaea can withstand a high saline concentration, allowing it to live in salt lakes and some marine environments?
Halobacterium
