A total of 300 cross-bred dairy cattle in Beni-Suef and El-Fayoum Governorates were screened for bovine tuberculosis using single intradermal (SID) cervical tuberculin test. 18 out of 300 (6%) tested cattle were found tuberculin positive. Blood samples from the positive reactors were tested by ELISA. ELISA plates were coated by either bovine purified protein derivative (PPD) or short term culture filtrate (ST-CF) antigens. The test sensitivity was compared at different serum dilutions. At serum dilution of 1/40, all of the 18 tuberculin positive samples, (100%), were ELISA positive using both ST-CF and PPD antigens, but at 1/80 dilution, 13 (72.22%) and 12 (66.66%) samples; at 1/160, 11 (61.11%) and 11 (61.11%) and finally at 1/320, 10 (55.55%) and 9 (50%) were ELISA positive on using ST-CF and PPD as a coating antigens respectively
