The infectivities of 66 Listeria monocytogenes isolates were assessed by intragastric inoculation of mice. Eight were poorly infective. Serovars 4b and 1/2 were more infective than serovars 3 and 4nonb. A noninfective isolate was cleared more rapidly from the cecum than were infective isolates, suggesting that survival in the gut may relate to infectivity.
通过给小鼠进行胃内接种来评估66株单核细胞增生李斯特菌分离株的感染性。其中8株感染性较差。血清型4b和1/2比血清型3和4非b的感染性更强。一株非感染性分离株从盲肠清除的速度比感染性分离株更快,这表明在肠道中的存活可能与感染性有关。
