{"doi":"10.1099/ijsem.0.006017","title":"Amygdalobacter indicium gen. nov., sp. nov., and Amygdalobacter nucleatus sp. nov., gen. nov.: novel bacteria from the family Oscillospiraceae isolated from the female genital tract","abstract":"Four obligately anaerobic Gram-positive bacteria representing one novel genus and two novel species were isolated from the female genital tract. Both novel species, designated UPII 610-J T and KA00274 T , and an additional isolate of each species were characterized utilizing biochemical, genotypic and phylogenetic analyses. All strains were non-motile and non-spore forming, asaccharolytic, non-cellulolytic and indole-negative coccobacilli. Fatty acid methyl ester analysis for UPII 610-J T and KA00274 T and additional isolates revealed C 16 : 0 , C 18 : 0 , C 18:1 ω9c and C 18:2 ω6,9c to be the major fatty acids for both species. UPII 610-J T had a 16S rRNA gene sequence similarity of 99.4 % to an uncultured clone sequence (AY724740) designated as Bacterial Vaginosis Associated Bacterium 2 (BVAB2). KA00274 T had a 16S rRNA gene sequence similarity of 96.5 % to UPII 610-J T . Whole genomic DNA mol% G+C content was 42.2 and 39.3 % for UPII 610-JT and KA00274 T , respectively. Phylogenetic analyses indicate these isolates represent a novel genus and two novel species within the Oscillospiraceae family. We propose the names Amygdalobacter indicium gen. nov., sp. nov., for UPII 610-J T representing the type strain of this species (=DSM 112989 T , =ATCC TSD-274 T ) and Amygdalobacter nucleatus gen. nov., sp. nov., for KA00274 T representing the type strain of this species (=DSM 112988 T , =ATCC TSD-275 T ).","journal":"INTERNATIONAL JOURNAL OF SYSTEMATIC AND EVOLUTIONARY MICROBIOLOGY","year":2023,"id":343357,"datarank":0.0,"base_score":0.0,"endowment":0.0,"self_citation_contribution":0.0,"citation_network_contribution":0.0,"self_endowment_contribution":0.0,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":14,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.8488,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2023-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":293735,"name":"Michele N.
