Fig. 4.—Types of Spore-formation in Schizomycetes. (After Zopf.)
A. Various stages in the development of the endogenous spores in a Clostridium—the small letters indicate the order.
B. Endogenous spores of the hay bacillus.
C. A chain of cocci of Leuconostoc mesenterioides, with two "resting spores," i.e. arthrospores. (After van Tieghem.)
D. A motile rodlet with one cilium and with a spore formed inside.
E. Spore-formation in Vibrio-like (c) and Spirillum-like (a b, a) Schizomycetes.
F. Long rod-like form containing a spore (these are the so-called "Köpfchenbacterien" of German authors).
G. Vibrio form with spore. (After Prazmowski.)
H. Clostridium—one cell contains two spores. (After Prazmowski.)
I. Spirillum containing many spores (a), which are liberated at b by the breaking up of the parent cells.
