In order to evaluate genetic variation between rabbit haemorrhagic disease virus (RHDV) isolates and to derive phylogenetic relationships, 56 virus isolates collected from various parts of France over a 7 year period (1988 to 1995) were examined. Analyses were carried out by direct nucleotide sequencing of PCR fragments of three genomic regions encoding the(More)
Commensal bacteria often have an especially rich source of glycan-degrading enzymes which allow them to utilize undigested carbohydrates from the food or the host. The species Ruminococcus gnavus is present in the digestive tract of ≥90% of humans and has been implicated in gut-related diseases such as inflammatory bowel diseases (IBD). Here we analysed the(More)
Two myxoma virus-rabbit hemorrhagic disease virus (RHDV) recombinant viruses were constructed with the SG33 strain of myxoma virus to protect rabbits against myxomatosis and rabbit viral hemorrhagic disease. These recombinant viruses expressed the RHDV capsid protein (VP60). The recombinant protein, which is 60 kDa in size, was antigenic, as revealed by its(More)
The gastrointestinal mucus layer is colonized by a dense community of microbes catabolizing dietary and host carbohydrates during their expansion in the gut. Alterations in mucosal carbohydrate availability impact on the composition of microbial species. Ruminococcus gnavus is a commensal anaerobe present in the gastrointestinal tract of >90% of humans and(More)
The metabolism of S. Typhimurium within infected host cells plays a fundamental role in virulence since it enables intracellular proliferation and dissemination and affects the innate immune response. An essential requirement for the intracellular replication of S. Typhimurium is the need to regenerate ATP. The metabolic route used to fulfil this(More)
BACKGROUND AND PURPOSE In the neurosurgery setting, incidence of surgical site infections (SSI) are considered as low to moderately low (1 to 10%). These infections are nevertheless a major problem because of the associated morbidity and mortality. A SSI survey system has been initiated in our neurosurgical unit. We report the incidence of SSI and(More)
The effect of antigen challenge on the airway responses to substance P and on the epithelial neutral endopeptidase (NEP) activity was investigated in aerosol sensitized guinea-pigs. In vivo, bronchial responses to aerosolized substance P were similar to the responses observed in antigen-challenged guinea-pigs and in the control groups. In contrast, when the(More)
