Infections with intestinal helminth and bacterial pathogens, such as enteropathogenic Escherichia coli, continue to be a major global health threat for children. To determine whether and how an intestinal helminth parasite, Heligomosomoides polygyrus, might impact the TLR signaling pathway during the response to a bacterial enteropathogen, MyD88 knockout and wild-type C57BL/6 mice were infected...
Escherichia coli 08 was the most frequent coliform isolated from the blood and liver of morbid and dead neonatal, colostrum-free piglets raised under extremely sanitary conditions. This strain accounted for 67 per cent of the typable E. coli. The next most numerous strain occurred at a frequency of 6 per cent. Hence, E. coli 08 was considered the main coli enteropathogen in our experimental, is...
Escherichia albertii is a recently recognized close relative of Escherichia coli. This emerging enteropathogen possesses a type III secretion system (T3SS) encoded by the locus of enterocyte effacement, similar to enteropathogenic and enterohemorrhagic E. coli (EPEC and EHEC). Shiga toxin-producing strains have also been identified. The genomic features of E. albertii, particularly differences ...
BACKGROUND Hafnia alvei is an opportunistic pathogen involved in various types of nosocomical infections. The species has been found to inhabit food and mammalian guts. However, its status as an enteropathogen, and whether the food-inhabiting strains could be a source of gastrointestinal infection remains obscure. In this report we present a draft genome of H. alvei strain FB1 isolated from fis...
The association of heat-stable enterotoxin (STa) produced by enterotoxigenic Escherichia coli 431 with isolated rat intestinal epithelial cells and brush border membranes was characterized. Specific binding of strain 431 125I-STa to a single class of specific high-affinity receptors was saturable and temperature dependent and reached a maximum between 5 and 10 min. A 1,000-fold excess of unlabe...
Over the past eight years, 70 countries have introduced rotavirus vaccines into their National Immunisation Programs and this has resulted in a rapid and dramatic impact on morbidity and mortality associated with all-cause and rotavirus-related gastroenteritis (GE). In Brazil, one of the worldwide early adopter countries of universal rotavirus vaccination, a significant decline in GE-related ho...
