RESUMEN

We report here the main characteristics of Coprococcus phoceensis strain Marseille-P3062T (CSUR P3062). The 16S rDNA sequencing and matrix-assisted laser desorption/ionization time-of-flight mass spectrometry spectrum analysis were used to identify and characterize this new anaerobic bacterial species, which was isolated from the left colon cleansing of a 25-year-old French man with Crohn's disease.

RESUMEN

A strictly anaerobic, motile, non-spore-forming, Gram-negative, rod-shaped bacterium designated Marseille-P3110T was isolated from the left colon cleansing of a 76-year-old Frenchwoman. Its 16S ribosomal RNA (rRNA) gene showed a 93.2% similarity level with the 16S rRNA of Dielma fastidiosa strain JC13, the closest species with a validly published name. The genome of Marseille-P3110T is 2 607 061 bp long with 35.99% G+C content. Of the 2642 predicted genes, 2582 were protein-coding genes and 60 were RNAs, including five 16S rRNA genes.

RESUMEN

Culturomics is a concept developing different culture conditions in order to enlarge our knowledge of the human microbiota through the discovery of previously uncultured bacteria. This enabled us to isolate six new species of the Bacteroides genus: Bacteroides mediterraneensis strain Marseille-P2644, Bacteroides ihuae strain Marseille-P2824, Bacteroides togonis strain Marseille-P3166, Bacteroides ndongoniae strain Marseille-P3108, Bacteroides ilei strain Marseille-P3208 and Bacteroides congonensis strain Marseille-P3132. Those bacteria are Gram-negative anaerobic bacilli. We describe here their phenotypic features, together with phylogenetic analysis, matrix-assisted laser desorption/ionization time-of-flight mass spectrometry spectrum, fatty acid composition, and genome sequencing and annotation.

RESUMEN

The taxonogenomic approach, including the culturomics techniques, is now currently used to isolate and characterize new bacteria. These approaches notably allowed us to discover six new species of the Actinomyces genus: Actinomyces ihuae strain SD1, Actinomyces bouchesdurhonensis strain Marseille-P2825, Actinomyces urinae strain Marseille-P2225, Actinomyces marseillensis strain Marseille-P2818, Actinomyces mediterranea strain Marseille-P3257 and Actinomyces oralis strain Marseille-P3109. Each is the type strain of the corresponding bacterial species. 16S ribosomal RNA gene sequence comparison was used to classify these strains among the Actinomyces genus. These strains are all Gram positive, rod shaped and facultative aerobic. We describe the main characteristics of each bacterium and present their complete genome sequence and annotation.

RESUMEN

OBJECTIVES: We aimed to assess the prevalence and risk factors for Chagas disease (CD) in Latin American immigrants and to evaluate the accuracy of diagnostic tests. Moreover, we offered to all positive subjects a complete free-of-charge clinical/instrumental evaluation as well as benznidazole treatment in order to stage the disease and verify drug tolerability. METHODS: A cross-sectional survey of CD among Latin Americans living in Milan and its metropolitan area was conducted between July 2013 and July 2014. Blood samples were tested for serologic evidence of CD together with a questionnaire covering demographic and clinical-epidemiological information. RESULTS: Forty-eight (9.6%) of the 501 tested subjects were conclusively diagnosed as having CD. The highest prevalence of CD was among those from Bolivia (43/169, 25.4%) and El Salvador (4/68, 5.9%). Older age (adjusted odds ratio (aOR)] 1.05, p =0.004), a Bolivian origin (aOR 8.80; p =0.003), being born in the department of Santa Cruz (aOR 3.72, p =0.047), having lived in mud houses (aOR 2.68; p =0.019), and having an affected relative (aOR 12.77, p =0.001) were independently associated with CD. The ARCHITECT Chagas test showed the highest sensitivity (100%) and specificity (99.8%). Twenty-nine of the subjects with CD (60.4%) underwent disease staging, 10 of whom (35.7%) showed cardiac and/or digestive involvement. Benznidazole treatment was associated with high frequency of adverse reactions (19/27, 70.4%) and permanent discontinuation (8/27, 29.6%). CONCLUSIONS: CD is highly prevalent among Bolivians and Salvadorans living in Milan. Regions with a large Latin American immigrant population should implement programmes of active detection and treatment.

RESUMEN

Strain Marseille-P2645T was isolated in a colon sample from a Frenchwoman who underwent a colonoscopy. Bacterial cells were Gram negative, non-spore forming, mobile and strictly anaerobic. The genome of strain Marseille-P2645T is 3 950 441 bp long and contains 3374 protein-coding genes. The DNA G+C content is of 51.66 mol%. Strain Marseille-P2645T exhibited a 92.9% sequence similarity with Bacteroides helcogenes strain P36-108T (GenBank accession no. CP002352), the phylogenetically closest species with standing in nomenclature. Strain Marseille-P2645T (= CSUR P2645 = DSM 103034) is therefore a candidate as a type species of a new genus belonging to the Bacteroidaceae family, for which the name of Mediterranea massiliensis gen. nov., sp. nov., is proposed.
