Ch, Chain of chromatic rodlets running from trophonucleus to kinetonucleus.
Mixed zoogloea found as a pellicle on the surface of vegetable infusions, &c.; it consists of various forms, and contains cocci (a) and rodlets, in series (b and c), &c. (x 540).
Rods or rodlets: slightly or more considerably elongated cells which are cylindrical, biscuit-shaped or somewhat fusiform.
(After de Bary.) a, a chain of motile rodlets still growing and dividing (bacilli).
The rodlets after three hours' culture in a drop of aqueous become septate later, and spores are developed in the segments.
Motile rodlets (X 1000).
Vegetative cells cylindric (rodlets), ellipsoid or ovoid, and straight.
Sporogenous rodlets cylindric, not altered in shape: - Bacillus (Cohn), non-motile; Bactrinium (Fischer), motile, with one polar flagellum (monotrichous); Bactrillum (Fischer), motile, with a terminal tuft of cilia (lophotrichous); Bactridium (Fischer), motile, with cilia all over the surface (peritrichous) .
Sporogenous rodlets, spindle-shaped: - Clostridium (Prazm.), motile (peritrichous).
Sporogenous rodlets, drumstick-shaped: - Plectridium (Fischer), motile (peritrichous).
C. Typical filaments and rodlets in the slimy sheaths.
It had grown and divided and broken up into eight rodlets (B); C shows further development at 8 P.M., D at 9.30 P.M.
