Effect of incubation temperature and serum content in agar overlay on plaque production by foot-and-mouth disease virus. 1967

C H Campbell

The numbers of plaques produced by foot-and-mouth disease virus in primary cultures of calf kidney cells conditioned to 24, 30, and 37 C were essentially the same if virus was absorbed at 37 C. Adsorption was as effective at 30 as at 37 C in cultures conditioned to the respective temperature, but 24 C was less effective under this condition. However, when the adsorption temperature for cultures conditioned to 37 C was decreased to 30 or 24 C, fewer plaques were produced than in cultures conditioned to and maintained at the lower temperatures during absorption. Comparison of the number of plaques produced in cultures overlaid with nutrient agar containing from 0.5 to 10% bovine serum revealed no difference in relation to serum concentration. However, plaque size was related directly to the concentration of serum in the overlay.

UI	MeSH Term	Description	Entries
D003470	Culture Media	Any liquid or solid preparation made specifically for the growth, storage, or transport of microorganisms or other types of cells. The variety of media that exist allow for the culturing of specific microorganisms and cell types, such as differential media, selective media, test media, and defined media. Solid media consist of liquid media that have been solidified with an agent such as AGAR or GELATIN.	Media, Culture
D005537	Aphthovirus	A genus of the family PICORNAVIRIDAE infecting mainly cloven-hoofed animals. They cause vesicular lesions and upper respiratory tract infections. FOOT AND MOUTH DISEASE VIRUS is the type species.	Equine rhinitis A virus,Equine rhinovirus 1,Aphthoviruses
D000362	Agar	A complex sulfated polymer of galactose units, extracted from Gelidium cartilagineum, Gracilaria confervoides, and related red algae. It is used as a gel in the preparation of solid culture media for microorganisms, as a bulk laxative, in making emulsions, and as a supporting medium for immunodiffusion and immunoelectrophoresis.
D013696	Temperature	The property of objects that determines the direction of heat flow when they are placed in direct thermal contact. The temperature is the energy of microscopic motions (vibrational and translational) of the particles of atoms.	Temperatures

D046508	Culture Techniques	Methods of maintaining or growing biological materials in controlled laboratory conditions. These include the cultures of CELLS; TISSUES; organs; or embryo in vitro. Both animal and plant tissues may be cultured by a variety of methods. Cultures may derive from normal or abnormal tissues, and consist of a single cell type or mixed cell types.
