Domain/Kingdom: Bacteria
firmicutes (morphology)
"strong skin". gram positive cell wall but some lack cell walls. a few can stain gram negative because they have a porous pseudo-outer membrane. LOW G+C GRAM POSITIVE BACTERIA. endospore formers, rods or cocci, can form chains
chlamydiae monophyletic group
chlamydiae, bacteriodetes, actinobacteria, spirochetes
infection cycle of chlamydia
Elementary body and reticulate body. the elementary body (spore, infectious) enters a cell, transforms into an RB, replicates, reforms EB's, released from cell
morphology of actinobacteria
HIGH G+C CONTENT GRAM POSITIVE BACTERIA. filamentous
one of the most common parasitic microbes
alphaproteobacteria
rhizobia belong to which phylum
alphaproteobacteria
groups in phylum proteobacteria are/aren't monophyletic
are NOT
genra of bacteriodetes
bacteriodes, provotella, porphyromonas
chlamydiae is sister to
bacteriodetes
porphyromonas gingivits
bacteriodetes that causes gingivitis
phylum that contains b bacteria that cause gonnorhea
betaproteobacteria
alphaproteobacteria interesting facts and diseases
endosymbiotic origin of mitochondria. rickettsia causes typhoid and rocky mountain spotted fever
phylum that contains campylobacter and helicobacter
epsionproteobacteria
what phylum does staphylococcus belong to
firmicute
what is the most ancestral phylum of bacteria
firmicutes
which phyla of microorganisms dominate the mammalian gut
firmicutes (100%) and bacteriodetes
bacteriodes and provotella
found in the gut
important genra of actinobacteria FRANK gave PSEUDO STREPTOMY MYC
frankia, streptomyces, mycobacterium, pseudonocardia
phylum that contains enterobacteriales and morphology, example of genra that are human pathogens
gammaproteobacteria. gram negative bacilli, pseudomonas, vibrio
morphology of proteobacteria
gram negative, flagella
Staphylococcus aureus
gram positive cocci, causes many different diseases
habitat and metabolism of firmicutes
habitat: soil, skin, mucous membrane, gut. metabolism: heterotrophic, anaerobic using SLP (except bacillus)
spirochetes morphology (2 interesting features)
helically coiled cells, gram negative, unique internal flagella between cell membrane and outer membrane
metabolic diversity of proteobacteria
heterotrophs and autotrophs, mostly facultative or obligate anaerobes
distinguishing importance of proteobacteria
include most of the well-studied bacteria such as E. coli
connection between bacteriodetes and microbiota
leaner individuals tended to have more bacteriodetes
pseudonocardia
mutualist of fungus-growing ants
major genra in firmicutes ENTER: MY CLOth BAg has COkESS
mycoplasma, clostridium, bacillus (anthraces, subtitles, thuringensis), listeria, staphylococcus lactobacillus, enterococcus, streptococcus
importance of actinobacteria
pharmaceuticals. antibiotics and anticancer drugs
importance of cyanobaceria
photosynthesis, important primary producers that fix 25% of earth's carbon, also fix nitrogen. most likely responsibly for earth's atmosphere becoming rich in oxygen
frankia
plant mutualists that fix nitrogen
important genus of cyanobacteria -occur in water- CHLORine
prochlorococcus
streptomyces
produce antibiotics
actinobacteria activity in soils (3 things)
produce geosmin which gives an earthy smell, help in decomposition of organic matter, symbionts of insects
what phylum does E. coli belong to
proteobacteria
proteobacteria monophyletic group
proteobacteria, acidobacteria, cyanobacteria
microbe implicated in lung infections of CF patients
pseudomonas aruginosa
MRSA
resistant to beta lactam antibiotics
bacteriodetes morphology
rod shaped
characteristics of bacteriodetes
sacharolytic. degrade complex polysaccharides
where do bacteriodetes occur
soil, sea water, symbionts of animals, sediments
where are actinobacteria found
soils.
treponema pallidum
spirochete that causes syphilis
what phylum does treponema palladium belong to and what disease does it cause
spirochete, syphillus
borrelia bugdorferi
spirochete: lyme disease
treponema spp
spirochete: symbionts of termites
actinobacteria are sister to
spirochetes
necrotizing fasciitis
staph aureus involved in up to 1/3 of cases
genra of spirochetes TREe BORR
treponema, borrelia
mycobacterium
tuberculosis
cyanobacteria morphology
very diverse morphoology
