Abstract
Results of a polyphasic taxonomic study on an unknown Gram-negative, facult atively anaerobic, coccobacillus-shaped organism isolated from an infected human gall bladder are presented. Phenotypic and molecular taxonomic studie s revealed the organism to be close to, but distinct from, organisms design ated CDC (Centers for Disease Control and Prevention) group DF-3. The unkno wn bacterium was readily distinguished from reference strains of Bacteroide s, Prevotella, Porphyromonas and related taxa by 16S rRNA gene sequencing, biochemical tests, analysis of cellular long-chain fatty acids and electrop horetic analysis of whole-cell proteins. Based on the results of the presen t study, it is proposed that the unknown bacterium be classified in a new g enus, Dysgonomonas, as Dysgonomonas gadei sp. nov. (type strain CCUG 42882( T) = CIP 106420(T)). In addition, a new species, Dysgonomonas capnocytophag oides sp. nov., is proposed to accommodate strains previously belonging to CDC group DF-3. The type species of the genus Dysgonomonas is Dysgonomonas gadei.
