Abstract

A total of 50 goats of smallholders and different farms from in and around Nagpur were investigated for tuberculosis 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, 4% (2/50) goats were found inconclusive by CITT and 4% positive by IFN-γ assay. However, in goats which found inconclusive in CITT, only those turned positive in IFN-γ assay. Hence, when CITT and IFN- γ used together lead to more accurate screening for tuberculosis in animals.
