Enterotoxigenic Escherichia coli (ETEC) in farm animals.
Animal diseases due to enterotoxigenic Escherichia coli (ETEC) typically appear as severe watery diarrhoea during the first few days of life (also a few days after weaning in pigs). ETEC adhere to the small intestinal microvilli without inducing morphological lesions and produce enterotoxins acting locally on enterocytes. This action results in the hypersecretion (of water and electrolytes) and...
متن کاملFrom cholera to enterotoxigenic Escherichia coli (ETEC) vaccine development
It was shown earlier that immune responses against cholera toxin (CT) as well as Vibrio cholerae lipopolysaccharide (LPS) or whole bacterial cells (WC) were protective and that these different antibody specificities co-operated synergistically for protection against experimental cholera. Similarly, antibodies against the heat-labile toxin (LT) and major colonization factors (CFs) of enterotoxin...
متن کاملEffect of bacteriophage in enterotoxigenic Escherichia coli (ETEC) infected pigs.
We evaluated effect of enterotoxigenic Escherichia coli (ETEC) specific lytic phage CJ12 in ETEC infected pigs. Phage was mixed with feed at a ratio of 1:1,000 (0.1%). One week after initially providing phage mixed feed, pigs were challenged orally with 10(11) CFU of ETEC and body weight, diarrhea score, bacterial CFU and phage PFU in the feces were measured. Pigs of phage treated groups C (10(...
متن کاملDraft genomes of four enterotoxigenic Escherichia coli (ETEC) clinical isolates from China and Bangladesh
BACKGROUND Enterotoxigenic Escherichia coli (ETEC) is an important pathogen that causes childhood and travelers' diarrhea. Here, we present the draft genomes of four ETEC isolates recovered from stool specimens of patients with diarrhea in Beijing, China and Dhaka, Bangladesh, respectively. RESULTS We obtained the draft genomes of ETEC strains CE516 and CE549 isolated in China, and E1777 and ...
متن کاملLeoA, B and C from Enterotoxigenic Escherichia coli (ETEC) Are Bacterial Dynamins
Escherichia coli (ETEC) strain H10407 contains a GTPase virulence factor, LeoA, which is encoded on a pathogenicity island and has been shown to enhance toxin release, potentially through vesicle secretion. By sequence comparisons and X-ray structure determination we now identify LeoA as a bacterial dynamin-like protein (DLP). Proteins of the dynamin family remodel membranes and were once thoug...
