ABSTRACT
Strain EL1T was isolated from a sinus sample of an 85-year-old man with chronic refractory sinusitis complicating ethmoidal adenocarcinoma. We studied its phenotypic and genomic characteristics. This is a Gram stain-positive, anaerobic and microaerophilic coccus. Cells are catalase negative, nonmotile and non-spore forming. The major fatty acids are saturated hexadecanoic acid (34%), unsaturated 9-octadecenoic acid (32%) and 9.12-octadecadienoic acid (21%). The 1.86 Mb long genome exhibits a 29.9% G+C content and contains 1750 protein-coding and 43 RNA genes. On the basis of these data, we propose the creation of the new human-associated bacterial species Peptoniphilus lacydonensis sp. nov.

This is a Gram-positive, facultative anaerobic, rod-shaped bacterium. We describe here the features of this organism, together with its complete genome sequence and annotation. The genome size is 6 719 043 bp with 49.6% G+C content and contains 6211 protein-coding and 65 sRNA genes, including four 5S rRNA genes, one 16S rRNA gene and one 23S rRNA gene.
ABSTRACT
Strain ND3T was isolated from the genital tract of a 28-year-old woman with bacterial vaginosis. This strain exhibited a 16S rRNA gene sequence similarity of 92.4% with Sutterella wadsworthensis, the phylogenetically closest species with standing in nomenclature. Strain ND3T was a strictly anaerobic Gram-negative rod and member of the family Sutterellaceae. It exhibited a genome of 2 476 884 bp containing 2175 protein-coding and 62 RNA genes. On the basis of these data, we propose the creation of 'Dakarella massiliensis' sp. nov. with strain ND3T (= CSUR P1938 = DSM 100447) as the type strain.

ABSTRACT
An obligate aerobic, Gram-negative, nonmotile and nonsporulating rod designated Marseille P2517 was isolated from the vaginal flora. We describe its features, annotate the genome and compare it to the closest species. The 16S rRNA analysis shows 93.03% sequence similarity with Weeksella virosa, the phylogenetically closest species. Its genome is 2 434 475 bp long and presents 38.16% G+C. On the basis of these data, it can be considered as a new genus in the Flavobacteriaceae family, for which we proposed the name Vaginella massiliensis gen. nov., sp. nov. The type strain is Marseille P2517T.

ABSTRACT
Strain FF10(T) (= CSUR P1489 = DSM 100884) was isolated from the oral cavity of a lizard (Varanus niloticus) in Dakar, Senegal. Here we used a polyphasic study including phenotypic and genomic analyses to describe the strain FF10(T). Results support strain FF10(T) being a Gram-positive coccus, facultative anaerobic bacterium, catalase-negative, non-motile and non-spore forming. The sequenced genome counts 2.46 Mb with one chromosome but no plasmid. It exhibits a G+C content of 40.4% and contains 2471 protein-coding and 45 RNA genes. On the basis of these data, we propose the creation of Streptococcus varani sp. nov.

ABSTRACT
SETTING: All India Institute of Medical Sciences and Rajan Babu Institute of Pulmonary Medicine and Tuberculosis, New Delhi, India. OBJECTIVE: To investigate the association of vitamin D receptor (VDR) polymorphisms and serum 25(OH)D with susceptibility to, and response to treatment of, multidrug-resistant tuberculosis (MDR-TB) in comparison with drug-susceptible pulmonary TB (DS-PTB) and healthy controls. DESIGN: Cross-sectional study. METHODS: A total of 897 participants from northern India were consecutively enrolled into three groups (MDR-TB 354, DS-PTB 338, controls 205). Genotypic and allelic frequencies of FokI, BsmI and TaqI VDR polymorphisms, and serum 25(OH)D, calcium and intact parathyroid hormone were measured in all participants. In those with active TB, disease severity, time to sputum smear and culture conversion were correlated with VDR genotype and biochemical parameters. RESULTS: FokI Ff genotype and TaqI t allele correlated positively with MDR-TB; Ff genotype and f allele of FokI frequency were higher in both TB groups. BsmI Bb genotype correlated inversely with MDR-TB. Serum 25(OH)D concentrations were significantly lowest in MDR-TB, correlating inversely with time to sputum smear conversion. CONCLUSIONS: VDR gene polymorphisms and hypovitaminosis D may predispose to MDR-TB. Lower serum 25(OH)D may increase time to MDR-TB sputum smear negativity.
