    • The outer longitudinal layer of the colon thins out into three discontinuous longitudinal bands known as tiniae coli (bands of the colon).

  • Histology of the Large Intestine

    • The large intestine has taeniae coli and invaginations (the intestinal glands), unlike the small intestines.
    • The longitudinal layer of the muscularis is reduced to three strap-like structures known as the taeniae coli—bands of longitudinal muscle fibers, each about 1/5 in wide.
    • A photograph of the large bowel (sigmoid colon) that shows multiple diverticula on either side of the longitudinal muscle bundle (Taenia coli).

  • Anatomy of the Large Intestine

    • The large intestine is much wider, and the longitudinal layers of the muscularis are reduced to three, strap-like structures known as the taeniae coli.
    • On the surface of the large intestine, bands of longitudinal muscle fibers called taeniae coli, each about 0.2 inches wide, can be identified.

  • Transcytosis

    • Shiga toxin secreted by entero-hemorrhagic E. coli has been shown to be transcytosed into the intestinal lumen.

  • Bacterial Flora

    • Escherichia coli is one of the many species of bacteria present in the human gut.

  • Polyps in the Colon

    • Multiple adenomatous polyps often result from familial polyposis coli or familial adenomatous polyposis, a condition that carries a very high risk of colon cancer.

  • Gallstones

    • Presence of gallstones in the gallbladder may lead to acute cholecystitis (an inflammatory condition characterized by retention of bile in the gallbladder) and may often result in a secondary infection by intestinal microorganisms, predominantly Escherichia coli and Bacteroides species.

  • Peritonitis

    • In most cases of perforation of a hollow viscus, mixed bacteria are isolated from the infection; the most common agents include Gram-negative bacilli like E. coli and anaerobic bacteria.
