Two hundred lactating animals (158 cattle and 42 buffaloes) of organized and unorganized farms were investigated for the bovine TB using comparative intradermal tuberculin test (CITT) and IFN-y assay. CITT was performed using avian and bovine PPD and IFN-y assay by Mycobacterium bovis gamma interferon test kit. Overall, 14.5% and 11.5% animals were found positive by CITT and IFN-y assay, respectively. However, 22.5% animals were detected TB positive th rough combination of both th e tests. So, both CITT and IFN-y assay, wh en used togeth er lead to more accurate screening for bovine TB in dairy h erd.
