culture | propagation of a mass of mo's in a lab culture medium |
culture medium | mixture of nutrients on which mo's are grown in the lab |
false-negative | test result denoting that condition is absent when it is actually present |
false-positive | test result denoting that a condition is present when it is actually absent |
fastidious | extremely delicate, difficult to culture, & involving specialized growth requirements |
immunization | process of becoming protected from a disease through vaccination |
