Primary Isolate

Primary isolate is a pure microbial or viral sample that has been obtained from an infected individual, rather than grown in a laboratory. In chemistry and bacteriology, the verb isolate means to obtain a pure chemical, bacteriological or viral sample. The noun 'isolate' refers to the sample itself.

According to the 'Bulletin of Experimental Treatments for AIDS, Year-End, 1999' glossary, a primary isolate is "HIV taken from an infected individual, as opposed to that grown in a laboratory."

Famous quotes containing the words primary and/or isolate:

    The traditional American husband and father had the responsibilities—and the privileges—of playing the role of primary provider. Sharing that role is not easy. To yield exclusive access to the role is to surrender some of the potential for fulfilling the hero fantasy—a fantasy that appeals to us all. The loss is far from trivial.
    Faye J. Crosby (20th century)

    The genius of any slave system is found in the dynamics which isolate slaves from each other, obscure the reality of a common condition, and make united rebellion against the oppressor inconceivable.
    Andrea Dworkin (b. 1946)
