Strain FF6(T) was isolated from the cervical abscess of a 4-year-old Senegalese boy, in Dakar, Senegal. MALDI-TOF MS did not provide any identification. This strain exhibited a 95.17% 16S rRNA sequence identity with Necropsobacter rosorum. Using a polyphasic study including phenotypic and genomic analyses, strain FF6(T) was an aero-anaerobic Gram-negative cocobacillus, oxidase positive, and exhibited a genome of 2,493,927 bp (1 chromosome but no plasmid) with a G+C content of 46.2% that coded 2,309 protein-coding and 53 RNA genes. On the basis of these data, we propose the creation of Necropsobacter massiliensis sp. nov.

Background: Left ventricular diastolic dysfunction (LVDD) is an important precursor of heart failure (HF), but little is known about its relationship with gut dysbiosis and microbial-related metabolites. By leveraging the multi-omics data from the Hispanic Community Health Study/Study of Latinos (HCHS/SOL), a study with population at high burden of LVDD, we aimed to characterize gut microbiota associated with LVDD and identify metabolite signatures of gut dysbiosis and incident LVDD.
Results: We included up to 1996 Hispanic/Latino adults (mean age: 59.

Our team in Europe has developed the routine clinical laboratory identification of microorganisms by matrix-assisted laser desorption ionization time-of-flight (MALDI-TOF) mass spectrometry (MS). To evaluate the utility of MALDI-TOF MS in tropical Africa in collaboration with local teams, we installed an apparatus in the Hôpital Principal de Dakar (Senegal), performed routine identification of isolates, and confirmed or completed their identification in France. In the case of discordance or a lack of identification, molecular biology was performed.
