“…The opposing school holds that the two reactions are intrinsically different and postulate that they are mediated by different T-cell subsets or lymphokines. Thus, from animal studies, Stanford et al (1981) drew a distinction between a macrophage-activating reaction, termed the Listeria-type reaction, that causes a skin-test reaction that peaks at 24 h, and the necrotic Koch-type reaction that peaks at about 48 h. Similar reactions are seen in man Stanford & Lema 1983). Rook (1983 c) has postulated that the Koch-type reaction is the result of a 'second signal', probably a lymphokine, delivered to the activated macrophage causing it to release a tissue necrosis factor.…”

“…Por outro lado, trabalhos assinalam que reações à prova tuberculínica de pequeno tamanho -tipo Listéria -estariam associadas ao efeito protetor do BCG, significando portanto imunidade, enquanto as de maior tamanho indicariam menor proteção ou seqüela de tuberculose. Estas são as reações do tipo Koch 6,7 .…”

“…Levando em conta que as reações do tipo Koch e do tipo Listéria, foram identificadas em crianças que apresentaram induração igual ou superior a 4mm, pode-se inferir a aplicação prática deste tipo de leitura, mesmo naquelas que seriam consideradas não reatoras, pelo teste de Mantoux 6 .…”

“…The smallest induration size considered for assessment was 5 mm. The qualitative assessment of Koch (turgid) and Listeria (non turgid) type of reactions was carried out according to the criteria of Stanford et al 3 The reaction was designated Koch's type of response ( Fig.1) if any 3 of the following changes were recorded.…”
