B IO 205 Topic 6 Study Guide
Questions and answ er s w ith
accur ate r ationales(PASSED)
Pasteur - answer Aseptic techniques inspired Joseph Lister
Carbolic acid - answer Joseph Lister applied carbolic acid (phenol) directly onto
damaged tissues- prevent infections
sterilization - answer -process of killing or removing all of the microorganisms in or
on a material
-sterile item is free of microbes, endospores, and viruses
disinfection - answer -eliminates most pathogens
-disinfectants are biocides
sanitation - answer -substantially reduce microbial population that meets
accepted health standards
antiseptic - answer used on living tissues
static - answer inhibiting, not killing, microbes
, cidal - answer kills microbes
pasteurization - answer brief heating to reduce number of spoilage organisms,
destroy pathogens (food)
soap - answer aids in mechanical removal of organisms
nosocomial infections - answer patients more susceptible to infection
pathogens more likely found in hospital setting
Pseudomonas - answer resistant to and can actually grow in some disinfectants
non-enveloped viruses - answer more resistant to disinfectants
mycobacterium spp. - answer mycolic acid- resistant
a common organisms that grow in certain chemical disinfectants is: - answer
pseudomonas
factors that affect microbial death rate - answer pH, temperature, presence of
organics, biofilm more resistant
moist heat kills microorganisms by: - answer irreversibly denatures proteins in
microbes, breaks H bonds, and changes shape of enzymes
