economic burden of clostridium difficile in five hospitals of the florence health care system in italy.despite the awareness about the increasing rates of clostridium difficile infection (cdi) and the economic burden arising from its management (prolonged hospitalization, laboratory tests, visits, surgical treatment, environmental sanitation), few studies are available in italy on the economic costs directly attributable to the cdi. the florence health care system has designed a study with the aim of describing the costs attributable to the cdi and defines the incremental economic burden associat ...201526604846
memory of germinant stimuli in bacterial spores.bacterial spores, despite being metabolically dormant, possess the remarkable capacity to detect nutrients and other molecules in their environment through a biochemical sensory apparatus that can trigger spore germination, allowing the return to vegetative growth within minutes of exposure of germinants. we demonstrate here that bacterial spores of multiple species retain memory of transient exposures to germinant stimuli that can result in altered responses to subsequent exposure. the magnitud ...201526604257
the aged gut in inflammatory bowel diseases.senescence is accompanied by various anatomical and functional alterations starting from mastication and deglutition and consequent modifications of nutrition. in addition, the widespread use of proton pump inhibitors and non-steroidal anti-inflammatory drugs in aged subjects weakens the gastric barrier, thus contributing to easier entry of microbes into the gastrointestinal tract. the microbiota of the elderly is less stable than that of younger adults, therefore, gut dysbiosis is more frequent ...201526603728
binding and entry of clostridium difficile toxin b is mediated by multiple domains.clostridium difficile is responsible for a number of serious gastrointestinal diseases caused primarily by two exotoxins, tcda and tcdb. these toxins enter host cells by binding unique receptors, at least partially via their combined repetitive oligopeptides (crops) domains. our study investigated structural determinants necessary for binding and entry of tcdb. deletion analyses identified tcdb residues 1372-1493 as essential for cytotoxicity in three cell lines. consistent with this observation ...201526602083
