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.
