Experiments were focused on the prevention of diarrhoea in weaned piglets by means of enterotoxigenic strains of Escherichia coli (ETEC) with colonizing factors K88 (F4). The process of immunization consisted of intramuscular administration of ETEC strain bacterin one day prior to weaning and oral administration of a live culture of non-pathogenic E. coli strain containing colonizing factors (O...

millions of diarrheal disease is made by enterotoxigenic e. coli (etec) each year, specifically in developing countries. in the pathogenesis of etec infections, the first phase is sticking of the bacterium to the minute intestinal epithelium, as a result of colonization factors (cfs) mediation and subsequently generate enterotoxins. these cfs in accordance with their structure are diverged into...

Synthetic oligonucleotides, complementary to unique sequences in the heat stable enterotoxin gene of Escherichia coli specific for humans, were prepared with a 30-atom spacer arm and a 3' terminal sulfhydryl group which was coupled to bromoacetyl-derivatized alkaline phosphatase. The resulting direct enzyme-linked oligonucleotide probes, containing one enzyme molecule per oligonucleotide, succe...

objectives: enterotoxigenic escherichia coli (etec) is one of the most common agents of diarrhea among other bacterial agents. designing and producing vaccine against these bacteria is one of the major purposes of world health organization (who). due to presence of diverse clones of etec strains in the world, the use of global vaccines for etec infection is controversial. b subunit of heat labi...

Foodborne diseases occur worldwide, including those acquired through the consumption of contaminated meat. This study aimed to investigate the prevalence of enterotoxigenic Staphylococcus aureus, Salmonella and Escherichia coli pathotypes in different meat types. Forty meat samples fresh (n=35) and frozen (n=5) were purchased from local markets in Jenin district, Palestine. Multiplex PCR was us...

The DNA colony hybridization assay was used to identify enterotoxigenic Escherichia coli among E. coli isolated from 803 swine with diarrhea at 10 farms in Thailand. Between 5 September and 8 December 1981, enterotoxigenic E. coli were identified in 40% of 58 litters of piglets under 10 days old and 17% of 29 litters between 10 and 21 days old with diarrhea at farms at four different locations ...

Experimental or naturally acquired subclinical infections with rotavirus caused a significant increase in mortality of infant mice after challenge with enterotoxigenic Escherichia coli B44.

Diarrhoeal diseases are one of the most important causes of illness and death all over the world. In Nigeria, the aetiology of diarrhoeagenic bacteria and the virulence of various Escherichia coli pathotypes have not been well-studied because most currently-published data were from the southwestern axis of the country. In total, 520 stool samples were collected from infants, young children, and...

Mortality and morbidity associated with Escherichia coli cause economic losses to the swine industry. Enterotoxigenic strains of E. coli affecting nursery-age pigs have become more difficult to treat because of increased antibiotic resistance, and alternatives to antibiotics are currently being sought. Our laboratory developed a defined culture of commensal bacteria of porcine gastrointestinal ...
