Studied by 1 personkoch’s postulates
take blood away from organism with illness
grow pathogen from the infected organism on an agar plate to form colonies
put pathogen into another healthy organism, this organism should get same disease
take blood from this ill organism and find the same pathogen
Gram - bacteria
do not retain violent colour when stained because extra outer membrane, more dangerous, more resistant to antibiotics = more harder to kill
coccus
spheres
bacillus
rod shape
spirillum
corkscrew shape
diplo
pair
staphylo
clumps
strepto
chain
gram + bacteria
stained purple, didn’t have extra cell membrane for protection, easier to kill
vaccines
major weapon in preventing viral disease
provide acquired immune response to pathogen
resemble pathogen but do not cause illness
antiviral drugs
prevent viral replication/assembly
useful against rapidly mutating viruses (HIV)
inactivated vaccine
pathogen killed by chemical, heat, radiation
most require booster shot to maintain immunity
eg. polio, rabies
attenuated vaccine
pathogen is active but weakened, preventing disease
most require single dose
