Morphology Pectinatus
CELLULAR  
Staining Gram-negative
Morphology Slightly curved rods, 0.7-0.8 um in diameter and 2.0-32 um or more in length, with rounded ends; they occur singly, in pairs, and only rarely in short chains. Shorter, younger cells do not show a helical shape, but the elongated older cells tend to form helices. After cultures have passed the stationary and declining phases, round cell forms are often observed
Motility Young cells move very actively, giving the appearance of an "X" shape as they swim. Older and longer cells have a snakelike motion as they move. Flagella emanate from only one side of a cell. Flagella are not limited to the center portion of the concave side of the cell as they are in the genus Selenomonas. The number of flagella per cell depends upon the cell size and its condition, but generally ranges from 1 to 23 or more.
