Genome sequences and phylogenetic analysis of K88- and F18-positive porcine enterotoxigenic Escherichia coli.
Porcine enterotoxigenic Escherichia coli (ETEC) continues to result in major morbidity and mortality in the swine industry via postweaning diarrhea. The key virulence factors of ETEC strains, their serotypes, and their fimbrial components have been well studied. However, most studies to date have focused on plasmid-encoded traits related to colonization and toxin production, and the chromosomal...

متن کاملComplete Genome Sequences of Two Porcine Enterotoxigenic Escherichia coli Strains
Enterotoxigenic Escherichia coli (ETEC) is one of the main causes of illness and death in neonatal and recently weaned pigs. Here, we sequenced the genomes of two ETEC strains that were previously used as inactivated vaccines in China.
متن کاملBromelain protects piglets from diarrhoea caused by oral challenge with K88 positive enterotoxigenic Escherichia coli.
BACKGROUND K88 positive enterotoxigenic Escherichia coli (K88+ ETEC) is an important cause of diarrhoea in young piglets. K88+ ETEC pathogenesis relies on attachment to specific glycoprotein receptors located on the intestinal mucosa. Proteolytic treatment of these receptors in vitro and in vivo prevents attachment of K88+ ETEC to piglet small intestines and may be of clinical use to prevent K8...
متن کاملPhylogenetic and molecular insights into the evolution of multidrug-resistant porcine enterotoxigenic Escherichia coli in Australia.
This study investigated the phylogeny and molecular epidemiology of Australian porcine enterotoxigenic Escherichia coli (ETEC) isolates (n=70) by performing multilocus sequence typing (MLST), random amplified polymorphic DNA (RAPD) analysis, virulence gene analysis, plasmid, bacteriocin, integron and antimicrobial resistance gene typing, and antimicrobial susceptibility phenotyping. Isolates of...
