Abstract
The materials used in experimentation must be clearly defined as to their purity. Experimental animals are standardized by specifying species, strain, sex, age, diet, housing and microflora; for these factors are important for obtaining clear results and for correct interpretations of the results obtained. Considerable efforts have been directed toward producing and controlling animals as pure materials for experimentation. Germfree (GF) rodents that are caesarean-derived into a sterile isolator, fed a sterilized diet and maintained aseptically, are desirable subjects for some types of experimentation because they have proven to be free from bacteria, protozoa, fungi and mycoplasma (1, 2, 3, 4). In the field of virology, possibly other fields (such as oncology, serology, and pathology) it is important to obtain “Virus-defined” or “virus-free” animals as reliable experimental tools.
