The aim of the studies was to determine the usefulness >f the ELISA test to detect antibodies against EBB virus n the milk of cows from the Wroclaw voivodship, where he test is to be used for the routine examination of milk. The results of this test were compared with blood sera ;xaminations by the ID test. The studies were done on 29 nilk samples including 17 bulk milk samples. A kit of ,Leukotest” acc. to Bommeli was used. Except for 4 cases, he results of both tests were identical. Positive results in he ELISA test obtained with milk samples negative in he ID test point to a high sensitivity of ELISA. The results obtained confirmed the usefulness of the ID :est with blood sera to detect and control EBB. On the 'arms where the program of EBB eradication has been ntroduced, the latest negative results in the ID test have jeen in most cases confirmed by ELISA. ELISA, as one )f the serological diagnostic methods, can be used to :xamine bulk milk in large farms free of EBB.
