Abstract

A phenotypic mixing (PM) test for detecting and assaying avian leukosis viruses (ALV) of the A, B, C, and D subgroups is described. An ALV and Rous sarcoma virus RSV-0) are phenotypically mixed by co-cultivating on C/O (cells susceptible to all subgroups of ALV) cells for a certain period. Then the RSV with the new virus property is assayed on C/E cells (cells resistant to infection with subgroup E leukosis/sarcoma viruses). The test is relatively simple and rapid, and its results are unequivocal. It is as sensitive as the more lengthy complement-fixation test (COFAL). The system is suitable for detecting avian leukosis viruses in samples such as heparinized blood, plasma, and embryo extracts.
