Autor: Victoria Mesa, Johanne Delannoy, Laurent Ferraris, Laure Diancourt, Christelle Mazuet, Frédéric Barbut, Julio Aires
Publikováno v: Microbiology Spectrum, Vol 11, Iss 6 (2023)
ABSTRACT Clostridium neonatale was described as a new species within the Clostridium genus cluster I sensu stricto. It was recovered from the gut microbiota of infants and has been associated with necrotizing enterocolitis (NEC), a severe gastrointes

Publikováno v: Gut Microbes, Vol 15, Iss 1 (2023)
ABSTRACTBacterial colonization in the gut plays a pivotal role in neonatal necrotizing enterocolitis (NEC) development, but the relationship between bacteria and NEC remains unclear. In this study, we aimed to elucidate whether bacterial butyrate end

Publikováno v: PLoS ONE, Vol 14, Iss 2, p e0212568 (2019)
BackgroundPremature neonates (PN) present multiple risk factors for high frequencies and high levels of colonization by C. difficile, yet data is missing about this specific pediatric population. Here, we investigated PN C. difficile carriage and col

Clostridia in premature neonates' gut: incidence, antibiotic susceptibility, and perinatal determinants influencing colonization.
Autor: Laurent Ferraris, Marie José Butel, Florence Campeotto, Michel Vodovar, Jean Christophe Rozé, Julio Aires
Publikováno v: PLoS ONE, Vol 7, Iss 1, p e30594 (2012)
BackgroundAlthough premature neonates (PN) gut microbiota has been studied, data about gut clostridial colonization in PN are scarce. Few studies have reported clostridia colonization in PN whereas Bacteroides and bifidobacteria have been seldom isol

Publikováno v: PLoS ONE, Vol 5, Iss 6, p e11083 (2010)
BACKGROUND: Fecal calprotectin has been proposed as a non-invasive marker of intestinal inflammation in inflammatory bowel disease in adults and children. Fecal calprotectin levels have been reported to be much higher in both healthy full-term and pr
