Christensenella massiliensis, a new bacterial species isolated from the human gut

AbstractWe describe the main characteristics of Christensenella massiliensis, strain Marseille-P2438T (CSUR P2438), isolated from a stool specimen of a 66-year-old patient

Genome sequence and description of Clostridium niameyense sp. nov., isolated from a human with marasmus in Nigeria

International audienceClostridium niameyense sp. nov. strain MT5 is the type strain of C. niameyense sp. nov., a new species within the genus Clostridia. C. niameyense is a Gram-positive, anaerobic bacillus. The strain MT5 (= CSUR P1468 = DSMZ 100441), whose genome is described here, was isolated from a faecal sample collected from a patient with anorexia and marasmus living in Nigeria. The genome is 2 542 841 bp long with 27.44% G + C content and consists of six scaffolds

“Streptomyces massilialgeriensis” sp. nov., a new bacterial species isolated from an extremely saline soil collected from the dry lake of Ank el Djamel in Algeria

We report here the main characteristics of “Streptomyces massilialgeriensis” strain S35T (CSUR = P3927), a new bacterial species within the Streptomyces genus, isolated from an extremely saline soil sample collected from the site of Garaet Ank Djemel in the Wilaya of Oum El Bouaghi, Algeria. Keywords: Culturomics, dry lake, saline soil, “Streptomyces massilialgeriensis”, taxono-genomic

‘Flaviflexus massiliensis’, a new bacterial species isolated from the human gut

Herein, we report the main characteristics of ‘Flaviflexus massiliensis’ strain SIT4T (CSURP1300), a new bacterium that was isolated from the stool specimen of a 2-year-old girl from Niger suffering from kwashiorkor

Bacterial culture through selective and non-selective conditions : the evolution of culture media in clinical microbiology

Microbiology has been largely developed thanks to the discovery and optimization of culture media. The first liquid artificial culture medium was created by Louis Pasteur in 1860. Previously, bacterial growth on daily materials such as some foods had been observed. These observations highlighted the importance of the bacteria's natural environment and their nutritional needs in the development of culture media for their isolation. A culture medium is essentially composed of basic elements (water, nutrients), to which must be added different growth factors that will be specific to each bacterium and necessary for their growth. The evolution of bacterial culture through the media used for their culture began with the development of the first solid culture medium by Koch, allowing not only the production of bacterial colonies, but also the possibility of purifying a bacterial clone. The main gelling agent used in solid culture media is agar. However, some limits have been observed in the use of agar because of some extremely oxygen-sensitive bacteria that do not grow on agar media, and other alternatives were proposed and tested. Then, the discovery of antimicrobial agents and their specific targets prompted the emergence of selective media. These inhibiting agents make it possible to eliminate undesirable bacteria from the microbiota and select the bacteria desired. Thanks to a better knowledge of the bacterial environment, it will be possible to develop new culture media and new culture conditions, better adapted to certain fastidious bacteria that are difficult to isolate

‘Halomonas massiliensis’ sp. nov., a new halotolerant bacterium isolated from the human gut
