   referred to in:

   • animal, animate being, beast, brute, creature, fauna - a living organism characterized by voluntary movement
   • flora, plant, plant life - (botany) a living organism lacking the power of locomotion
   associated with:

   • virulence, virulency - extreme harmfulness (as the capacity of a microorganism to cause disease)
   • transmitter, vector - any agent (person or animal or microorganism) that carries and transmits a disease
   • bacteremia, bacteriaemia, bacteriemia - transient presence of bacteria (or other microorganisms) in the blood
   • highly infective - (of a microorganism) extremely infective
   • motile - (of spores or microorganisms) capable of movement
   • immotile, nonmotile - (of spores or microorganisms) not capable of movement
   is a type of: being, organism - a living thing that has (or can develop) the ability to act or function independently
   subtypes:

   • monad - (biology) a single-celled microorganism (especially a flagellate protozoan)
   • intestinal flora - harmless microorganisms (as Escherichia coli) that inhabit the intestinal tract and are essential for its normal functioning
   • virus - (virology) ultramicroscopic infectious agent that replicates itself only within cells of living hosts; many are pathogenic; a piece of nucleic acid (DNA or RNA) wrapped in a thin coat of protein
   • moneran, moneron - organisms that typically reproduce by asexual budding or fission and whose nutritional mode is absorption or photosynthesis or chemosynthesis
   • bacteria, bacterium - (microbiology) single-celled or noncellular spherical or spiral or rod-shaped organisms lacking chlorophyll that reproduce by fission; important as pathogens and for biochemical properties; taxonomy is difficult; often considered to be plants
   • bug, germ, microbe - a minute life form (especially a disease-causing bacterium); the term is not in technical use
   • pathogen - any disease-producing agent (especially a virus or bacterium or other microorganism)
   • protoctist - any of the unicellular protists
   • protist, protistan - free-living or colonial organisms with diverse nutritional and reproductive modes
