“…Furthermore, in both Figs 1 and 2, strain Marseille-P4126 T was clustered with Fannyhessea vaginae strains. So, this suggested that strain Marseille-P4126 T belongs to a new species in the genus Fannyhessea rather than the genus Atopobium , as previously suggested [8]. However, as this strain was deposited in only one culture collection, we could not formally propose its reclassification as a new species into the genus Fannyhessea .…”

“…Finally, we identified in the phylogenetic analysis three other previously published strains, Marseille-P2300 T , Marseille-P3359 T and Marseille-P4126 T , proposed to belong to the new species ‘ Olsenella timonensis ’ [6], ‘ Olsenella congonensis ’ [7] and ‘ Atopobium massiliense ’ [8], respectively, and re-evaluated their taxonomic status.…”

Five novel bacterial strains, Marseille-P1476T (=CSURP1476T=DSM 100642T), Marseille-P3256T (=CSURP3256T=CECT 9977T), Marseille-P2936T (=CSURP2936T=DSM 103159T), Marseille-P2912T (=CSURP2912T=DSM 103345T) and Marseille-P3197T (=CSURP3197T=CCUG 71847T), were isolated from various human specimens. These five strains were not identified at the species level by matrix-assisted laser desorption/ionization time of flight mass spectrometry. Following 16S rRNA gene sequence comparisons with the GenBank database, the highest nucleotide sequence similarities of all studied strains were obtained to members of the paraphyletic genus Olsenella . A polyphasic taxono-genomic strategy (16S rRNA gene-based and core genome-based phylogeny, genomic comparison, phenotypic and biochemical characteristics) enabled us to better classify these strains and reclassify Olsenella species. Among the studied strains, Marseille-P1476T, Marseille-P2936T and Marseille-P3197T belonged to new species of the genus Olsenella for which we propose the names Olsenella massiliensis sp. nov., Olsenella phocaeensis sp. nov. and Olsenella urininfantis sp. nov., respectively. Strains Marseille-P2912T and Marseille-P3256T belonged to a new genus for which the names Thermophilibacter provencensis gen. nov., sp. nov. and Thermophilibacter mediterraneus gen. nov., sp. nov. are proposed, respectively. We also propose the creation of the genera Parafannyhessea gen. nov., Tractidigestivibacter gen. nov. and Paratractidigestivibacter gen. nov. and the reclassification of Olsenella umbonata as Parafannyhessea umbonata comb. nov., Olsenella scatoligenes as Tractidigestivibacter scatoligenes comb. nov., and Olsenella faecalis as Paratractidigestivibacter faecalis comb. nov.

“…As an opportunistic pathogen, Rothia could cause endocarditis, meningitis, and bacteremia in people with low immunity [ 24 ]. Atopobium was the causative agent of bacterial vaginitis, which could also cause bacteremia in people with low immunity [ 25 , 26 ]. Some other reports on the respiratory tract of PTB are different from our data, such as Zelin Cui [ 19 ] reported that Stenotrophomonas , Cupriavidus , Pseudomonas , Thermus , Sphingomonas and other foreign bacteria are unique to the airway of PTB; Yuhua Zhou reported [ 17 ]: the dominant genus of bacteria in the tuberculosis patient’s lower respiratory tract is Cuprophyll rather than Streptococcus .…”

Airway microecology in rifampicin-resistant and rifampicin-sensitive pulmonary tuberculosis patients

Background Pulmonary tuberculosis is a chronic infectious disease of the respiratory system. It is still one of the leading causes of death from a single infectious disease, but it has been stuck in the study of a single pathogen. Recent studies have shown that many diseases are associated with disruption of the native microbiota. In this study we investigated the occurrence of tuberculosis and the correlation between drug resistance and respiratory flora. High-throughput 16 S rRNA gene sequencing was used to characterize the respiratory microbiota composition of 30 tuberculosis (TB) affected patients and compared with 30 healthy (H) controls. According to their Gene Xpert results, 30 pulmonary tuberculosis patients were divided into 12 persons in the drug-sensitive group (DS0) and 18 persons in the drug-resistant group (DR0). The microbial flora of the two were compared with the H group. Results The data generated by sequencing showed that Firmicutes, Proteus, Bacteroides, Actinomyces and Fusobacterium were the five main bacterial phyla detected, and they constituted more than 96% of the microbial community. The relative abundances of Fusobacterium, Haemophilus, Porphyromonas, Neisseria, TM7, Spirochetes, SR1, and Tenericutes in the TB group was lower than that of the H group, and Granulicatella was higher than the H group. The PcoA diagrams of the two groups had obvious clustering differences. The Alpha diversity of the TB group was lower than that of the H group, and the Beta diversity was higher than that of the H group (P < 0.05). The relative abundance of Streptococcus in the DS0 group was significantly higher than that in the DR0 group (P < 0.05). Conclusion Pulmonary tuberculosis can cause disorders of the respiratory tract microbial flora, in which the relative abundance of Streptococcus was significantly different between rifampicin-sensitive and rifampicin-resistant patients.

“…It was first discovered in rat faeces in 2009 and was categorized as a member of the Porphyromonadaceae family based on 16S rRNA gene sequence analysis [ 1 ]. To date, there are seven species isolated as part of the Butyricimonas genus: B. virosa , B. synergistica , B. paravirosa , B. faecihominis , B. phoceensis , B. faecalis , and B. vaginalis [ 1 , 2 , 3 , 4 , 5 ]. B. virosa is the only pathogenic species within the genus.…”

Butyricimonas virosa is a Gram-negative bacillus, which was first discovered in rat faeces in 2009. To date, only seven human infections have been reported in literature. To our knowledge, this is the first reported case of peritoneal dialysis (PD)-related peritonitis due to B. virosa. A 65-year-old Chinese man presented to the hospital with complaints of dizziness and vomiting. On admission, the drained peritoneal dialysate was cloudy. He was empirically treated as a case of PD-related peritonitis with intraperitoneal (IP) cefazolin, ceftazidime, and gentamicin. B. virosa was isolated from peritoneal fluid sample and the antibiotics were changed to IP imipenem and amikacin. Three weeks after completion of the antibiotics, the patient presented again with cloudy peritoneal dialysate and blood stained diarrhoea. IP imipenem and amikacin were recommenced. Multiple peritoneal dialysate samples were sent to the microbiology laboratory, but this time no microorganism was isolated. Colonoscopy examination revealed the presence of extensive rectosigmoidal ulcerations. IP imipenem was replaced with IP piperacillin-tazobactam when the patient developed imipenem-associated neurotoxicity at Day 9 of treatment. The patient recovered fully after completing 3 weeks of IP piperacillin-tazobactam and 2 weeks of IP amikacin. This is the first reported case of PD-related peritonitis due to B. virosa. Susceptibility data for B. virosa are scarce, but a 3-week course of IP piperacillin-tazobactam, imipenem, or meropenem could be potentially useful in treating PD-related peritonitis caused by this organism.
