Abstract
- Scanning electron microscopy demonstrated that the cecum of the guinea-pig is colonized by numerous spiral-shaped bacteria; these microorganisms, which adhere to mucosa at one end, were found exclusively on the brush border of the surface epithelium. The membranes of sectioned bacteria have a set of electron-dense bands girdling the tip adhered to epithelium. Freeze-fracture replicas of the bacteria revealed the prokaryote-eukaryote junction as a set of ridges on the P-face of outer membrane; the numerous particles of E-face were arranged in parallel rows; on the other hand, the apical plasma membrane and subjacent cytoplasm of epithelium occupied by the spiral-shaped bacteria did not show a structural counterpart. Observations suggest that one end of the spiral-shaped bacteria possesses specialized membrane components that permit specific attachment to the apical surface of epithelial cells.
