Enumeration of Bacteroides species in human faeces by fluorescent in situ hybridisation combined with flow cytometry using 16S rRNA probesLionel Rigottier-Gois
Institut National de la Recherche Agronomique, Unité d Ecologie et de Physiologie du Système Digestif, Domaine de Vilvert, Jouy en Josas Cedex, France
Syst Appl Microbiol 26:110-8. 2003..This work showed that fluorescent in situ hybridisation is a tool appropriate for a high-resolution analysis of the species composition of complex ecosystems and especially of the Bacteroides group within the faecal microbiota...
Molecular analysis of the digestive microbiota in a gnotobiotic mouse model during antibiotic treatment: Influence of Saccharomyces boulardiiMarie Claude Barc
Departement de Microbiologie, Universite Paris Sud XI, Faculte de Pharmacie, EA 4043, Unité sous contrat INRA Ecosystème Microbien Digestif et Santé, 92296 Chatenay Malabry Cedex, France
Anaerobe 14:229-33. 2008..This quicker recovery of normal intestinal microbiota equilibrium after antibiotic therapy could be a mechanism for S. boulardii preventive effect on antibiotic-associated diarrhea in humans...
Modulation of Lactobacillus casei in ileal and fecal samples from healthy volunteers after consumption of a fermented milk containing Lactobacillus casei DN-114 001RifViolaine Rochet
Unité d Ecologie et Physiologie du Système Digestif, INRA, Bat 405, Domaine de Vilvert, 78350 Jouy en Josas, France
Can J Microbiol 54:660-7. 2008..This is related to a high stability in the composition of dominant groups of the gut microbiota. Data from ileal samples are scarce and our study confirms the potentiality for interaction between probiotics and the human immune system...
Survival of Bifidobacterium animalis DN-173 010 in the faecal microbiota after administration in lyophilised form or in fermented product - a randomised study in healthy adultsViolaine Rochet
Unité d Ecologie et Physiologie du Système Digestif, Institut National de la Recherche Agronomique, Jouy en Josas, France
J Mol Microbiol Biotechnol 14:128-36. 2008..In conclusion, we show that the lyophilised form of B. animalis DN-173 010 survives transit and could represent a more convenient form to administer for long-term clinical trials...
Validation of fluorescent in situ hybridization combined with flow cytometry for assessing interindividual variation in the composition of human fecal microflora during long-term storage of samplesViolaine Rochet
Institut National de la Recherche Agronomique, Unité d Ecologie et Physiologie du Système Digestif, Bat 405, INRA, Domaine de Vilvert, 78352 Jouy en Josas Cedex, France
J Microbiol Methods 59:263-70. 2004..It represents an extended time compared with the 2-month period currently recommended. This will give more flexibility for applying this technology in epidemiological studies including a large number of samples...
Design and validation of 16S rRNA probes to enumerate members of the Clostridium leptum subgroup in human faecal microbiotaChristophe Lay
Institut National de la Recherche Agronomique, , , Domaine de Vilvert, 78352 Jouy en Josas Cedex, France
Environ Microbiol 7:933-46. 2005..The cluster Faecalibacterium prausnitzii was the dominant component of the C. leptum subgroup and 20% of the latter subgroup remained unidentified at the species level...
Effects of orally administered Lactobacillus casei DN-114 001 on the composition or activities of the dominant faecal microbiota in healthy humansViolaine Rochet
Institut National de la Recherche Agronomique, Unité d Ecologie et Physiologie du Système Digestif, Batiment 405, Domaine de Vilvert, 78 352 Jouy en Josas Cedex, France
Br J Nutr 95:421-9. 2006..casei DN-114 001 was accompanied by a high, transient increase in the quantity of this strain in the faeces of all of the subjects without markedly affecting biochemical or bacteriological factors...
Survival and metabolic activity of selected strains of Propionibacterium freudenreichii in the gastrointestinal tract of human microbiota-associated ratsAnnaig Lan
INRA, Agrocampus Rennes, UMR1253, Science et Technologie du Lait et de I Oeuf, F 35000 Rennes, France
Br J Nutr 97:714-24. 2007..Such alterations may have an impact on gut health and will thus be taken into consideration for further in vivo investigations on probiotic potentialities of P. freudenreichii...
The key role of segmented filamentous bacteria in the coordinated maturation of gut helper T cell responsesValerie Gaboriau-Routhiau
INRA, U910, Unité Ecologie et Physiologie du Système Digestif, Domaine de Vilvert, 78350 Jouy en Josas, France
Immunity 31:677-89. 2009..This bacterium, already known as a potent inducer of mucosal IgA, likely plays a unique role in the postnatal maturation of gut immune functions. Changes in the infant flora may thus influence the development of host immune responses...
Composition and metabolism of the intestinal microbiota in consumers and non-consumers of yogurtElise Alvaro
Unité d Ecologie et de Physiologie du Système Digestif, Institut National de la Recherche Agronomique, Jouy en Josas, France
Br J Nutr 97:126-33. 2007..0001 and r 0.43, P=0.018, respectively). Apart from these effects, which can be considered beneficial to the host, no other major differences could be detected regarding the composition and metabolic activity of intestinal microbiota...
Isoflavones and functional foods alter the dominant intestinal microbiota in postmenopausal womenThomas Clavel
Institut National de la Recherche Agronomique, , Jouy-en-Josas, France
J Nutr 135:2786-92. 2005..In conclusion, this is the first human study that shows changes in the diversity and composition of dominant bacterial communities in response to dietary supplementation with hormone-related compounds combined with functional foods...
