microbilogy study guide Flashcards
state of active growth of microorganisms
vegetative state
typical method of bacteria reproduction in which cell divides that into two equal parts
binary fission
cannot be destroyed by extreme heat or cold and is an abnormal pathogenic protein
prion
the state of being soiled by contact with infectious organisms
contamination
study of microorganisms
microbiology
capable of producing disease
pathogen
needs oxygen ,requiring the presence of air or free oxygen
aerobic
unit of measurement that is extremely small 1/25000 in and 1/1000 milimeter
micron
bacteria that can live in the absence of atmospheric oxygen , doesn’t require oxygen
anaerobic
capable of forming a thick wall around themselves enabling them to survive in adverse conditions
endospores
measure of alkanity or acidity on a scale
PH
how are staph infections spread
Direct contact with infected individual or by touching contaminated surfaces
give one example of a fungus infection
athletes foot , ringworm of the scalp , candida, thrush and vulvovaginitis
what is a staphylococcus classified as
gram positive
what is not gram positive
pseudomonas aeruginosa
four examples of gram positive bacteria
staphylococcus
streptococcus
enterococcus
mycobacterium tuber/leprae
clostridium bo/pe
bacillius anthracis
geobacillus specices
incubation period for ebola after exposure
2-21 days
what can e.coli cause
diarrhea, utis,pneumonia and respitory /illness
what can be found on hair & skin , useful to break down sewage and can produce toxins
microbes
HAI
healthcare- associated infections
how do you identify bacteria
shape, color change and oxygen needs
neisseria gonorrhoeae is most likely to grow where
mucus membrane of the reproductive system
which virus is not tranmitable by an airborne droplet
ebola
list of difficulty cleaning prions
prions are difficult to remove or deactivate so cleaning and sterilizing are ineffective
pseudomonas aeruginosa shape
rod shaped bacillius
this bacteria is normally found in soil
acinetobacter
difficulties of cleaning items contaminated w prions
:disposable items should be used in thiscase
:heat sensitive items should not be used they will likely be destroyed
high risk tissue
what is a prion
CJD
