Escherichia coli Heat - labile Enterotoxin NUCLEOTIDE SEQUENCE
We report the complete DNA sequence of the Escherichia coli elt A gene, which codes for the A subunit of the heat-labile enterotoxin, LT. The amino acid sequence of the LT A subunit has been deduced from the DNA sequence of elt A. The LT A subunit starts with methionine, ends with leucine, and comprises 264 amino acids. The computed molecular weight of LT A is 29,673. The A subunit of cho...
متن کاملPlasmid-mediated properties of a heat-stable enterotoxin-producing Escherichia coli associated with infantile diarrhea.
The plasmid mediation and transmissibility of heat-stable enterotoxin production and multiple antibiotic resistance have been demonstrated for Escherichia coli O78:K80:H12 epidemiologically incriminated in a hospital outbreak of infantile diarrhea. The conjugal transfer of a 67 X 10(6) - and a 30 X 10(6)-dalton plasmid was associated with the transfer of resistances and enterotoxin production, ...
متن کاملThe Prevalence of Enteroaggregative Escherichia coli in cases of Diarrhea in Gorgan, IRAN
Abstract Background and objectives: Diarrhea is one of the main cases of morbidity and mortality among children in developing countries. Enteroaggregative Escherichia coli (EAggEC) is an emerging diarrheal pathogen that has been associated characteristically with persistent diarrhea among infants, particularly in the developing Counties. Therefore, we decided to study the prevalence of enteroag...
متن کاملProperties of synthetically produced Escherichia coli heat-stable enterotoxin.
The properties of a synthetically produced peptide composed of the same primary structure of 18 amino acids described for human Escherichia coli heat-stable enterotoxin were compared with those of purified heat-stable toxin obtained by bacterial growth. The dosage required to evoke fluid secretion in the suckling mouse and rat ligated ileal loop assays was the same for both toxins. The antigeni...
متن کاملAn outbreak of diarrhea caused by Escherichia coli serogroup O169:HNM harboring a coding gene for enteroaggregative E. coli heat-stable enterotoxin 1 (astA) in Fukui Prefecture.
