Some Features of Campylobacter sputorum subsp. mucosalis subsp. nov., nom. rev. and Their Taxonomic Significance

Abstract

Strains of C. sputorum ssp. mucosalis isolated from intestinal adenomatosis from several sources were studied. The results supported the contention that this organism should be regarded as a distinct subspecies of C. sputorum. Since the name of this organism was not included on the Approved Lists of Bacterial Names, it is proposed as a revived name. The type strain is FS253/72 (= NCTC 11000). The guanine-plus-cytosine content of the DNA of this organism supports its inclusion within the genus Campylobacter but in its hydrogen dependence this organism shows clear similarities to the human oral vibrios and to Vibrio succinogenes. C. sputorum ssp. mucosalis possesses an unusual type c cytochrome and in this way it appears to differ from V. succinogenes. It may be differentiated readily from other members of the species C. sputorum by salt and glycine tolerance tests or by serological techniques.
