C57Bl/6 mice were infected with Strongyloides ratti. Susceptibility to infection was ascertained by quantifying the numbers of larvae in the faeces 1 week after infection. Resistance to infection was transferred by pooled immune serum and mesenteric lymph node (MLN) cells obtained 2 and 3 weeks after infection. There was no additive effect when immune serum and MLN cells were given together. Protection was not conferred by MLN cells 1, 4 or 6 weeks after infection nor by spleen cells taken 1--6 weeks after infection. There was, however, a mild non-specific reduction in larval excretion after transfer of either normal or immune spleen cells. These data indicate that both humoral and cell-mediated immune responses may confer resistance to infection in murine strongyloidiasis.
将C57Bl/6小鼠感染鼠类圆线虫。通过量化感染后1周粪便中的幼虫数量来确定感染易感性。感染后2周和3周获得的混合免疫血清和肠系膜淋巴结(MLN)细胞可传递抗感染能力。当免疫血清和MLN细胞同时给予时,没有相加效应。感染后1、4或6周的MLN细胞以及感染后1 - 6周获取的脾细胞均不能提供保护作用。然而,正常或免疫脾细胞转移后,幼虫排泄有轻度非特异性减少。这些数据表明,体液免疫和细胞介导的免疫反应均可赋予小鼠类圆线虫病抗感染能力。
