Human colostrum contains IgA antibodies reactive to colonization factors I and II of enterotoxigenic Escherichia coli.
Diarrhea is an important cause of morbidity and mortality amongst infants of low socio-economic levels in developing countries and in travelers who visit such areas. Enterotoxigenic E. coli strains express two sets of virulence-associated factors: enterotoxins (heat-stable toxins or heat-labile toxins) and colonization factors. Studies have shown that breast-feeding protects infants against inf...
متن کاملAncestral lineages of human enterotoxigenic Escherichia coli.
Enterotoxigenic Escherichia coli (ETEC) is a common cause of diarrhea among children living in and among travelers visiting developing countries. Human ETEC strains represent an epidemiologically and phenotypically diverse group of pathogens, and there is a need to identify natural groupings of these organisms that may help to explain this diversity. Here, we sought to identify most of the impo...
متن کاملAdditive protective effects of colostral antipili antibodies in calves experimentally infected with enterotoxigenic Escherichia coli.
With oral infection of calves by an enterotoxigenic Escherichia coli strain carrying K99, F41, and FY adhesins, colostrums from cows vaccinated against either K99+F41 or FY did not provide protection, but a mixture of the two colostrums did. The association of antibodies directed against the different adhesins is more effective than antibodies directed against one adhesin alone for colostral pr...
متن کاملClonal Relatedness of Enterotoxigenic and Enteropathogenic Escherichia coli Isolates from Diverse Human, Foods and Calf Sources
Background: Foodborne infection caused by EnterotoxigenicEscherichia coli (ETEC) and Enteropathogenic Escherichia coli (EPEC) is one of the major health problems, particularly in the developing countries. Therefore, it is vital to identify the origin of food contamination to plan control strategies efficiently. Method: A tota...
متن کاملIdentification of Enterotoxigenic Escherichia coli
Alkaline phosphatase-conjugated (AP) 26-base oligonucleotide DNA probes were compared with the same probes labeled with y_32p for the identification of heat-labile (LT) and heat-stable (ST) enterotoxigenic Escherichia coli (ETEC). The AP oligonucleotide probes were as sensitive as the radiolabeled (RL) probes in detecting LT and STA-2 target cell DNA, but the AP ST probe, which differed from ST...
