Epidemiology, molecular characterisation and toxin regulation of enterotoxigenic Escherichia coli (ETEC) isolated from children with diarrhoea
… emphasis on enterotoxigenic Escherichia coli (ETEC), as well as the role of host environmental factors in the regulation of the ETEC enterotoxins. We studied the prevalence, seasonality, antibiotic resistance and severity of disease of diarrhoeas caused by DEC in children aged less than five …

Studies on the Expression and Regulation of Enterotoxins and Colonization Factors in Enterotoxigenic Escherichia coli (ETEC)
Enterotoxigenic Escherichia coli (ETEC) is one of the most common causes of acute watery diarrhoea in developing countries, particularly among local children less than five years and is also the most common cause of diarrhoea in travellers to ETEC endemic areas. The infection is transmitted by …

A Multiepitope Subunit Vaccine for Enterotoxigenic Escherichia Coli (ETEC) Expressing LT, STA, STB, and STX2E Toxins
<p>Enterotoxigenic Escherichia coli (ETEC) are the main cause of diarrhea in young animals (and humans). Neonatal and post-weaning diarrhea causes significant economic losses to swine and other livestock producers worldwide. Currently, there is no effective vaccine to protect young animals, such as …

Investigations of enterotoxigenic E. Coli (ETEC) intestinal colonization in neonatal mice and human shedding of panchol, a new live attenuated oral cholera vaccine
… Vibrio cholerae and Enterotoxigenic E. Coli (ETEC) are enteropathogens that are global causes of cholera and traveler’s diarrhea which are responsible for millions of diarrhea cases every year. ETEC and cholera are primarily found in Sub-Saharan Africa and Asia, particularly in nations with …

Whole Genome Sequencing of Enterotoxigenic Escherichia coli
Enterotoxigenic Escherichia coli (ETEC) infections are a common cause of diarrhea but little is known about the evolution and genomic composition of ETEC. The main aim of this thesis was to generate a large collection of whole genome sequenced ETEC isolates to study the evolution of such bacteria …

Studies of Carbohydrate-Binding Proteins from Enterotoxigenic Escherichia coli
… and vaccines. Enterotoxigenic Escherichia coli (ETEC) is a well-known causative agent of diarrheal disease. The first step in the pathogenesis of ETEC infections is adhesion of the bacterium to the small intestinal epithelium, mediated by colonization factors (CFs). Two of the most common CFs are …

Interaction of enteroluminal neutrophils and the Escherichia coli heat-stable enterotoxin b with porcine small intestine
… strains of enterotoxigenic Escherichia coli (ETEC) attracted greater numbers of neutrophils into the lumen and wall of the intestine than did a nonenteropathogenic strain of E. coli. Ligated loops of small intestine in 8-week-old pigs were used in attempts to identify the attributes of ETEC …

Effect of feeding fumaric or citric acid on weanling pig performance and selected intestinal digesta measurements at varying times postweaning
… with 10¹⁰ enterotoxigenic E. coli (0157:K88) (ETEC) at d 3, 7 and 14 postweaning. Organic acids had no measurable effect on intestinal pH, Cl- or VFA profile. ETEC challenge increased jejunum lactic acid concentration, lower colon VFA concentration and severity of scouring. Postweaning age …

Impact of dietary fiber and exogenous carbohydrases in weaned pigs
… caused by enterotoxigenic Escherichia coli (ETEC) is an economically important disease in the swine industry. Previous results regarding the impact of soluble versus insoluble fiber on PWD in weaned pigs have been conflicting. This highlights the need to better understand the mechanisms by …

Development of a Subunit Vaccine Against Bovine Diarrhea Caused by K99 Enterotoxigenic Escherichia coli and Bovine Viral Diarrhea Virus
… industry. Enterotoxigenic Escherichia coli (ETEC), particularly strains expressing K99 (F5) fimbriae and heat-stable type I (STa) enterotoxin is the predominant bacterial cause of diarrhea in calves; whereas bovine viral diarrhea virus (BVDV) causes diarrhea and other illness to cattle at all …

Screening for Pathogenic Escherichia Coli in the Chattahoochee River, Columbus, Georgia
… PCR protocol for the human, bovine, and avian ETEC. Our results show that most isolated <em>E. coli</em> strains are not 0157:H7 or ETEC. However, nested PCR specific for human enterotoxigenic <em>E. coli</em> amplified target sequences in some tested colonies, which may indicate humans as a …

Plant-based Multicomponent Vaccines against Enteric Diseases
… cholera, rotavirus and enterotoxigenic E.coli (ETEC), we have constructed transgenic potato plants that synthesize the cholera toxin B and A2 subunits, the rotavirus enterotoxin NSP4 22 amino acid epitope and the ETEC fimbrial antigen CFA/L To use cholera toxin as a carrier molecule for delivery …

Development and characterization of Shigella multiepitope fusion antigen (MEFA) for a broadly protective subunit vaccine against shigellosis with extended utility against enterotoxigenic Escherichia coli.
… against enterotoxigenic Escherichia coli (ETEC), which was referred to as ShecVax. Upon co-administration in mice, Shigella MEFA and MecVax synergistically induced robust antibody responses against both Shigella and ETEC antigens, with significant neutralization ability against bacterial …

Immunomodulatory effects of whole yeast cells and capsicum in weanling pigs challenged with pathogenic escherichia coli
… the experiment. The pigs challenged with ETEC showed clear signs of infection, such as diarrhea and F18 E.coli at 5 days post-inoculation (DPI), while the control animals showed no signs of infection and had no detectable levels of F18 E. coli throughout the study. Both capsicum and whole …

Characterization of E. coli strains from rural communities in the Vhembe District (Limpopo South Africa)
… using Colilert® Quanti-trays®/2000 method to detect the presence of Escherichia coli. Positive E. coli samples were further identified using multiplex polymerase chain reaction (m-PCR) to determine the pathogenic strains of E. coli. Transmission pathways were established using identified …

Characterization, Stabilization and Formulation Design of IgG and Secretory IgA Monoclonal Antibody Candidates during Storage and Administration
… mAbs against enterotoxigenic Escherichia coli (ETEC) is examined with the idea that passive immunization by pathogen-specific immunoglobulins, by oral delivery to infants, is promising approach to provide “instant” protection against ETEC. Secretory IgA (sIgA) is of particular interest because …

Utilizing High Temporal Resolution Stable Isotope, Sap-Flux, and Eddy Covariance Measurements to Partition Daily Evapotranspiration in an Oak Woodland
… the stable isotope technique compared to T/ETEC or T/ET0. When normalizing fT for either δ18O and δ2H, the overestimation was reduced to 4 - 12%, suggesting there may be a systematic bias to the CGM leading to overestimation of fT in natural systems. When comparing δ18O and δ2H within the …
