Volunteer challenge with enterotoxigenic Escherichia coli that express intestinal colonization factor fimbriae CS17 and CS19.
Human challenges with enterotoxigenic Escherichia coli (ETEC) have broadened our understanding of this important enteropathogen. We report findings from the first challenge studies using ETEC-expressing colonization factor fimbria CS17 and CS19. LSN03-016011/A (LT, CS17) elicited a dose-dependent effect, with the upper dose (6 × 10(9) organisms) causing diarrhea in 88% of recipients. WS0115A (L...
متن کاملF1C fimbriae play an important role in biofilm formation and intestinal colonization by the Escherichia coli commensal strain Nissle 1917.
Bacterial biofilm formation is thought to enhance survival in natural environments and during interaction with hosts. A robust colonizer of the human gastrointestinal tract, Escherichia coli Nissle 1917, is widely employed in probiotic therapy. In this study, we performed a genetic screen to identify genes that are involved in Nissle biofilm formation. We found that F1C fimbriae are required fo...
متن کاملExpression of P fimbriae of uropathogenic Escherichia coli strains.
The occurrence of P fimbriae in a total of 222 uropathogenic Escherichia coli (UPEC) strains was investigated. Out of the total, 31 (14%) were P fimbriated. Of 24 pyelonephritogenic E. coli strains, three (13%) with P fimbriae occurred in children with clinical pyelonephritis, and of 198 E. coli strains 29 (15%) occurred in children with cystitis. Prevalence of P fimbriae of E. coli strains was...
متن کاملColonization of rectovaginal Escherichia coli and group B streptococci in mothers and on infants\' body surface and their related risk factors
Background: Microorganisms that cause early neonatal sepsis are usually already colonized rectovaginal area in mothers. The most common of these organisms is group B streptococci (GBS) and intestinal gram-negative bacteria mostly Escherichia coli (E.coli). The use of prophylactic antibiotics against GBS has increased in recent years. This study aimed to determine the current situation and frequ...
متن کاملThe Role of Long Polar Fimbriae in Escherichia coli O104:H4 Adhesion and Colonization
A renewed interest in Shiga toxin-producing Escherichia coli (STEC) strains was sparked due to the appearance of an outbreak in 2011, causing 3,816 diarrheal cases and some deaths in Europe. The causative strain was classified as enteroaggregative E. coli of serotype O104:H4 that had acquired Shiga toxin genes. The ability of STEC O104:H4 to cause disease relies greatly on the bacteria's capaci...
