Habitat and Function
Soil formation and stabilization
(breakdown of organic matter and development of biofilms)
Why are prokaryotic organisms important for stability and thriving of an environment?
Staphlococcus epidermis eats dead skin cells off the body
S. epidermis = food
humans = don't care
What is an example of commensalism?
- proteobacteria
- cytophaga-Fusobacterium-Bacteroides (CFB)
- spirochetes
What are the subcategories of a gram-negative stain?
actinobacteria and firmicutes
What are the two groups that gram-positive is classified into?
too small to be evaluated by the gram stain
Define atypical.
It changes and develops throughout time as the body gains and discards microbes to better fit it's needs.
What happens to the microbiome over time?
Population A: harmed
Population B: unaffected
What type of symbiotic relationship is amensalism?
rickettsia spp. and chylamydia spp.
Examples of Alphaproteobacteria
-low G+C gram-positive bacteria
-high G+C gram-positive bacteria
What are the subcategories of a gram-positive stain?
the oldest microbe to which all microbes can be traced back.
What is the last universal common ancestor?
present, appearing, or found everywhere
define ubiguitous
competitive and cooperative
What are the different interaction types between populations?
What type of bacteria is specific to the delta proteobacteria class?
sulfate-reducing bacteria (SRB)
meaning to have inconsistent stain results
Define gram variable
they only require small amounts of oxygen in their environment
what is microaerophillic bacteria?
Process of converting nitrogen gas into ammonia
What is nitrogen fixation?
microorganisms that are only temporarily found in the human body.
(they can be pathogenic organisms)
Define transient microbiata.
Which proteobacteria group is coined as having "a wide range of metabolic strategies and can survive a range of environments"?
betaproteobacteria
clostridium
streptococcus
lactobacillus
enterococcus
bacillus
staphylococcus
What are the prominent genre's of the firmicutes phylum?
bacteria exhibit a variety of morphological types, some of which are identical to other bacteria. In particular, bacteria that can express more than one morphology, including that normally associated with common species of Staphylococcus, have frequently been isolated from cancers.
Define polymorphic bacteria.
They are metabolically flexible, extremely resilient, and adaptable to new environments
What helps prokaryotes be present in every environment?
the relationship between humans and a pathogen
What is an example of parasitism?
pseudomonas
pasteurella
haemophilus
Vibrio
legionella
enterobacter family
What are the prominent genera of gammaproteobacteria?
actinobacteria
Which classification of gram - positive contains a high G+C content?
have to be within a host cell
these organisms are...
inactive metabolically when out of a host cell
can't create the ATP they need on their own
Define obligate intracellular pathogens.
