hanging-drop culture a culture in which the material to be cultivated is inoculated into a drop of fluid attached to a coverglass inverted over a hollow slide.
primary culture a cell or tissue culture made by direct transfer from a natural source to an artificial medium.
selective culture one grown on a medium, usually solid, that has been supplemented to encourage the growth of a single species of microorganism. It may also include substances that inhibit the growth of other species.
shake culture a culture made by inoculating warm liquid agar culture medium in a tube and shaking to distribute contents evenly. Incubation of the resolidified culture allows the development of separated colonies; especially adaptable to obligate anaerobes.
slant culture one made on the surface of solidified medium in a tube which has been tilted to provide a greater surface area for growth.
culture-specific syndrome folk illnesses that are unique to a particular culture or geographical area. Each illness has a cluster of symptoms, signs, and behavioral changes that are recognized by members of the culture; usually, they also have a range of symbolic meanings and culturally agreed-upon treatments.
