Diagnosis of Bovine Tuberculosis in Lactating Cattle and Buffaloes by Comparative Intradermal Tuberculin Test and Bovine Gamma-Interferon Immunoassay
Abstract:
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-γ assay. CITT was performed using avian and bovine PPD and IFN-γ assay by Mycobacterium bovis gamma interferon test kit. Overall, 14.5% and 11.5% animals were found positive by CITT and IFN-γ assay, respectively. However, 22.5% animals were detected TB positive through combination of both the tests. So, both CITT and IFN-γ assay, when used together lead to more accurate screening for bovine TB in dairy herd.
