Immunohistochemical demonstration of varied bacterial antigens ((a) BCG, (b) Bacillus cereus, (c) Treponema pallidum, (d) MPT64, (e) LAM, and (f) PAB). The cytoplasm of macrophages infiltrating around the fat droplet exhibits clear cross-reactivity with varied bacterial antigens. Immunoreactivity of T. pallidum antigens is relatively weak.
