Resistance and susceptibility to Listeria monocytogenes in mice was found to be related to (i) the innate ability of the nonimmune macrophages to kill or inhibit the growth of the organism during the first 24 to 48 h after infection, and (ii) the time of onset of acquired cell-mediated resistance. Resistant C57Bl/6 mice were 10 times more efficient than susceptible BALB/c mice at suppressing the early growth of Listeria in the liver. Furthermore, the onset of acquired immunity occurred 24 to 48 h earlier in C57Bl/6 than in BALB/c mice. Acquired immunity was measured by (i) fall in bacterial numbers in spleen and livers of infected mice (ii) adoptive transfer of immunity to normal mice by using spleen cells from infected mice, (iii) delayed-type hypersensitivity skin testing, and (iv) uptake of tritiated thymidine by lymphocytes in the spleen.
研究发现,小鼠对单核细胞增生李斯特菌的抗性和易感性与以下因素有关:(i)非免疫巨噬细胞在感染后最初24至48小时内杀死或抑制该菌生长的先天能力,以及(ii)获得性细胞介导抗性的起始时间。抗性C57Bl/6小鼠在抑制肝脏中李斯特菌早期生长方面比易感BALB/c小鼠效率高10倍。此外,C57Bl/6小鼠获得性免疫的起始时间比BALB/c小鼠早24至48小时。通过以下方法测定获得性免疫:(i)感染小鼠脾脏和肝脏中细菌数量的下降,(ii)用感染小鼠的脾细胞将免疫过继转移给正常小鼠,(iii)迟发型超敏皮肤试验,以及(iv)脾脏中淋巴细胞对氚化胸腺嘧啶核苷的摄取。
