Development of an immunoenzyme test system for detecting antibodies to commercial strains of feed yeasts

ELISA as a specific and highly sensitive test system was used for the examination of large groups of workers employed in the production of fodder protein to detect antibodies to the production strains of fodder yeast. The results yielded by ELISA correlated well with those obtained by the serological luminescent techniques, but antibody titers determined by means of ELISA are 10-20 times higher.
