BACKGROUND Macrophage activation by cytokines provides only a partial explanation of antimycobacterial immunity in man. Because cytolytic T lymphocytes have been shown to contribute to immunity in animal models of intracellular infection, the generation of mycobacterial antigen specific cytotoxic T cells was examined in the peripheral blood of patients with tuberculosis. METHODS Subjects comp...
139 children with bacteriological or histological proof of active tuberculosis were given the Mantoux tuberculin test while they were inpatients at Port Moresby General Hospital.

Fever was uncommon but in 15 of 21 patients the ESR was elevated. Leucocytosis was noted in seven of 20 patients. Autoantibodies were r...
We have previously shown that young adults living in a rural area of northern Malawi showed greater gamma interferon (IFN-gamma) responses to purified protein derivatives (PPD) prepared from environmental mycobacteria than to PPD from Mycobacterium tuberculosis. In order to define the mycobacterial species to which individuals living in a rural African population have been exposed and sensitize...

In this month's Journal, Dr. Rangel-Frausto and colleagues add to accumulating evidence reinforcing the pressing need to develop a workable alternative t...
