Microorganism in the Environment Flashcards
Bacteria reproduce by splitting into two is known as
binary fission
one kind of bacteria in a culture media
pure culture
culture media selective to grow specific organism
selective media
indicators that they are producing acids/alkalines
dyes
is useful in isolation and differentiation of the various gram-negative bacilli and enteric bacilli, generally known as coliforms and fecal coliforms respectively.
acyl methylene blue agar
Invasion of a host by a microorganism with subsequent establishment and multiplication of the agent.
infection
accidental transfers of organisms from one natural environment to another.
contamination
Sources of infectious agents / contaminants are humans, animals and non-living materials.
contamination
is an individual mass of bacterial growth on the surface of the agar.
colony
All the bacteria in a ____came from one single bacteria, and thus all are identical to one another.
colony
when grown on a medium, shows specific growth appearance or characteristics.
bacterium
It varies with the type of agar/broth medium, nutrients, and dyes present in the medium
colony
different forms of bacteria
punctiform
circular
irregular
