Journal ArticleDOI
GABA Production by Human Intestinal Bacteroides spp.: Prevalence, Regulation, and Role in Acid Stress Tolerance.
Nize Otaru,Nize Otaru,Kun Ye,Denisa Mujezinovic,Laura Berchtold,Florentin Constancias,Fabián A. Cornejo,Adam Krzystek,Tomas de Wouters,Christian Braegger,Christophe Lacroix,Benoit Pugin +11 more
TL;DR: It is shown that the production of GABA is regulated by pH, and that the GAD-system acts as a protective mechanism against acid stress in Bacteroides, mitigating cell death and preserving metabolic activity, and may represent the only amino acid-dependent acid tolerance system in Bactseroides.
Journal ArticleDOI
Colorectal cancer-associated Streptococcus infantarius subsp. infantarius differ from a major dairy lineage providing evidence for pathogenic, pathobiont and food-grade lineages.
Dasel W. M. Kaindi,Wambui Kogi-Makau,Godfrey Lule,Bernd Kreikemeyer,Pierre Renault,Bassirou Bonfoh,Bassirou Bonfoh,Nize Otaru,Thomas Schmid,Leo Meile,Jan Hattendorf,Jan Hattendorf,Christoph Jans +12 more
TL;DR: Phylogenetic relationships of East African human (EAH) isolates to those of dairy and pathogenic origin were analysed to better estimate potential health implications via FDP consumption and shared ancestry for the EAH and WAD clade could support the separation of pathogenic, pathobiont/commensal and food lineages.
Journal ArticleDOI
Risk factors for the carriage of Streptococcus infantarius subspecies infantarius isolated from African fermented dairy products.
Kossia D. T. Gboko,Sylvain G. Traoré,Aimé R. Sanhoun,Jérôme Kirioua,Nize Otaru,Fabienne Kurt,Fabienne N. Jaeger,Julia Isenring,Dasel W. M. Kaindi,Bernd Kreikemeyer,Pierre Renault,Jan Hattendorf,Leo Meile,Christoph Jans,Roland Nguetta,Bassirou Bonfoh +15 more
TL;DR: Analysis of Sii population structure through the SBSEC multi locus sequence typing assay revealed a close relationship across human and dairy isolates, possibly linked to a Kenyan human isolate.
Journal ArticleDOI
Traditional milk transformation schemes in Côte d'Ivoire and their impact on the prevalence of Streptococcus bovis complex bacteria in dairy products.
Aimé R. Sanhoun,Sylvain G. Traoré,Kossia D. T. Gboko,Jérôme Kirioua,Fabienne Kurt,Nize Otaru,Patriz Iten,Dasel W. M. Kaindi,Bernd Kreikemeyer,Pierre Renault,Daouda Dao,Jan Hattendorf,Jan Hattendorf,Leo Meile,Marina Koussemon,Christoph Jans,Bassirou Bonfoh,Bassirou Bonfoh +17 more
TL;DR: The observed production practices and the high diversity of Sii/SBSEC supports in-depth investigations on Sii ecology niche, product safety and related technology in the dairy value chain potentially affecting large population groups across sub-Saharan Africa.
