Caedibacter caryophila sp. nov. lives in the macronucleus of certain strains of Paramecium caudatum. The type strain is 221, carried in P. caudatum C221. C. caryophila is distinguished from other caedibacteria on the basis of host specificity, R body morphology, behavior of R bodies, and guanine-plus-cytosine content of its deoxyribonucleic acid.
