Etymology
N.L. n. <i>cecum</i> [from Latin <i>caecum</i> (or <i>cecum</i>) <i>intestinum</i>, caecum], caecum; L. suff. -<i>cola</i> (from L. n. <i>incola</i>), dweller, inhabitant; N.L. n. <i>cecicola</i>, caecum-dweller.
Ecology
Source
isolated from mouse cecal mucosa. The type strain was isolated from scrapings of the cecal mucosa of a conventional laboratory mouse (ICr/Br Swiss; Harlan-Sprague-Dawley, Indianapolis, Ind.).
Morphology
Cells are non-spore-forming, slightly curved rods (0.5 × 2.5-5 µm), and occur singly and in pairs. Actively motile at 37°C in anaerobic broth by means of 20 to 35 flagella which are inserted along the concave side and occasionally along one end of the cell. The flagella appear as a single, subterminal fascicle when cells are examined by phase-contrast microscopy. Surface colonies are white, mucoid, granular in appearance, 1.5 to 3 mm in diameter, and circular with smooth edges.
