The next
challenge facing the invading bacteria involves colonization
of the intestine through attachment (Lucas and Lee,
2000). The Salmonella cells must also be able to undergo
proliferation as well as evade any further barriers, such
as pH or acid shock that may try to hamper their colonization
(Lucas and Lee, 2000). The preferred entry point
for Salmonella is the Peyer’s patches in the distal ileum
(Jones, 1997).
