Two new bacteria isolated from vagina of a patient with vaginosis: Atopobium massiliense sp. nov. and Butyricimonas vaginalis sp. nov.

Two new bacterial strains, Marseille-P4126 (=CSURP4126) and Marseille-P4593 (=CSURP4593), were isolated from the vaginal sample of a French woman with vaginosis. These strains were identified and characterized using the taxonogenomics method. The findings from phylogenetic tree interpretation, phenotypic criteria and genomic analysis provided here distinctly display that Atopobium massiliense sp. nov. and Butyricimonas vaginalis sp. nov. are new members of the genus Atopobium and Butyricimonas, respectively.

Description of Clostridium cagae sp. nov., Clostridium rectalis sp. nov. and Hathewaya massiliensis sp. nov., new anaerobic bacteria isolated from human stool samples.

Using culturomics methods, three strains were isolated, identified and characterized following the taxonogenomics concept. Clostridium cagae strain Marseille-P4344T (=CSURP4344), Clostridium rectalis strain Marseille-P4200T (=CSURP4200) and Hathewaya massiliensis strain Marseille-P3545T (=CSURP3545) were isolated from human stool samples. The phylogenetic reconstruction, phenotypic criteria and genomic analyses were carried out and demonstrated that these three bacteria are different from previously known bacterial species with standing in nomenclature and were classified as new members of the Clostridiaceae family.
