S.YR 1986 T1 Cross-reactions in cell mediated Immunity induced by atypical mycobacteria JF Journal of Medical Microbiology, VO 21 IS 1 SP 35 OP 38 DO https://doi.org/10.1099/00222615-21-1-35 PB Microbiology Society, SN 1473-5644, AB Summary Cross-reactivity in the delayed hypersensitivity response to mycobacteria of different Runyon groups was tested in Swiss white mice immunised with live mycobacteria. All the strains tested gave cross-reactions and, generally, slow growers gave stronger cross-reactions with other slow growers than with rapid growers and vice versa. Sonicates of cross-reacting mycobacteria were also tested for their ability to generate activated macrophages in mice immunised with Mycobacterium avium. All the mycobacterial sonicates generated activated macrophages but a sonicate of Salmonella typhi did not. The sonicate of M. tuberculosis H37Rv also generated activated macrophages, which indicates that there might be protective cross-reactions between M. tuberculosis and atypical mycobacteria., UL https://www.microbiologyresearch.org/content/journal/jmm/10.1099/00222615-21-1-35
