Transcriptional profiling of C. difficile 630E strain vs. an Hfq antisense after 7.5h of growth inTYt. Two-conditions experiments, 630E strain vs. Hfq antisense grown in TYt, 4 biological replicates for each condition.
ORGANISM(S): Peptoclostridium difficile 
Clostridium difficile is an emergent human pathogen and the most common cause of nosocomial diarrhea. Our recent deep-sequencing data strongly suggest the importance of RNA-based mechanisms for the control of gene expression in C. difficile. The RNA chaperon protein Hfq is a key component of post-tr...

Summer mortality of the Pacific oyster Crassostrea gigas is the result of a complex interaction between oysters, their environment and pathogens. Heredity appears to be a major factor determining the sensitivity of oysters to summer mortality, allowing resistant (R) and susceptible (S) lines to be p...
ORGANISM(S): Crassostrea gigas 
Background Triploidy can occur in all species but is often lethal in birds and mammals. In amphibian, invertebrates and numerous species of fishes, triploid animals are viable and undistinguishable from diploid individuals. Gametogenesis is often affected and most animals are sterile for at least o...

Mechanisms allowing P. freudenreichii adaptation to digestive stresses have been only studied in vitro so far. Our aim was therefore to study P. freudenreichii metabolic adaptation to intra-colonic conditions in situ. We maintained a pure culture of P. freudenreichii CIRM-BIA1, contained in a dialys...
ORGANISM(S): Propionibacterium freudenreichii 
Background The Pacific oyster Crassostrea gigas (Mollusca, Lophotrochozoa) is an alternative and irregular protandrous hermaphrodite. Little is known about the genetic and phenotypic bases of sex determinism in oysters, and little more about the molecular pathways regulating reproduction. We have re...
ORGANISM(S): Crassostrea gigas 
Originating from Northeast Asia, the Pacific oyster Crassostrea gigas has been introduced into a large number of countries for aquaculture purpose. Following introduction, the Pacific oyster has turned into an invasive species in an increasing number of coastal areas, notably in Northern Europe. To ...
