|Abstract:||Culture filtrate proteins (CFPs) of M. bovis were produced by culturing the organism for a period of 3 weeks. These CFPs elicited a good delayed hypersensitivity (DTH) reaction in cattle and guinea pig. However, CFPs showed least cross–reactivity when tested in guinea pigs sensitized with M. bovis BCG and M. phlei. CFPs were found to be well recognized by T–cells of single intradermal test (SIDT) positive cattle and were also sero-reactive. Lymphocyte transformation assay revealed the culture filtrate antigens as major T-cell antigens. CFPs induced a good interferon gamma release as compared to conventional antigen, PPD, thereby highlighting their diagnostic capabilities.|
