OBJECTIVE To compare the tuberculin test and IFNγ production induced by culture filtrate proteins(CFPs) and Mycobacterium tuberculosis-specific CFP-10 antigens in rh...
Monocytes isolated from the peripheral blood of tuberculin-positive and tuberculin-negative donors were exposed to PPD, extensively washed, and incubated with autologous or homologous lymphocytes. Lymphocyte transformation was measured morphologically and by incorporation of (14)C-labeled thymidine. Monocytes from tuberculin-positive subjects induced transformation of autologous lymphocytes in ...

BACKGROUND Repeat tuberculin skin tests may be false positive due to boosting of waned immunity to past mycobacterial exposure. We evaluated whether an ELISPOT test could identify tuberculosis (TB) contacts with boosting of immunity to non-tuberculous mycobacterial exposure. METHODOLOGY/PRINCIPAL FINDINGS We conducted tuberculin and ELISPOT tests in 1665 TB contacts: 799 were tuberculin test ...
P ERIODIC REPORTS HAVE EMPHASIZED the lack of stability of repeated tuberCulin skin tests in children. Kunofsky and Katz1 reported on two large groups in two schools for mental defectives. Reversion rates of 4 to 19 per cent were found.
