Barbour AH, Rampling A, Hormaeche CE. Variation in the infectivity of Listeria monocytogenes isolates following intragastric inoculation of mice. Infect Immun. 2001;69(7):4657-60.
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.
