Implication

Experimental study demonstrates increased Salmonella typhimurium shedding in cecum-altered chickens, indicating ceca are nonessential for establishing intestinal infection.

Key Points

To evaluate whether the ceca are essential for establishing and maintaining Salmonella typhimurium intestinal infection in chickens.
Orally inoculated intact control chickens and surgically altered chickens (having ligated or surgically removed ceca) with Salmonella typhimurium and ferric oxide marker.
Monitored infection progression and transit dynamics by collecting and analyzing serial samples of feces and cecal contents.
Salmonellae first appeared in feces within 1.5 to 22 hours, compared to 3 to 5 hours for ferric oxide, whereas bacteria were not isolated from cecal contents until 24 hours post-inoculation.
Chickens with ligated or surgically removed ceca exhibited higher fecal shed rates than intact controls, providing no evidence that ceca are required to establish or sustain infection.
