Unique chromosomal regions associated with virulence of an avian pathogenic Escherichia coli strain.
We have found an avian pathogenic Escherichia coli (APEC) plasmid, pAPEC-O2-ColV, which contains many of the genes associated with APEC virulence and also shows similarity in content to a plasmid and pathogenicity island of human uropathogenic E. coli (UPEC). To test the possible role of this plasmid in virulence, it was transferred by conjugation along with a large R plasmid, pAPEC-O2-R, into ...
Antibiotic resistance among avian bacterial isolates is common and is of great concern to the poultry industry. Approximately 36% (n = 100) of avian, pathogenic Escherichia coli isolates obtained from diseased poultry exhibited multiple-antibiotic resistance to tetracycline, oxytetracycline, streptomycin, sulfonamides, and gentamicin. Clinical avian E. coli isolates were further screened for th...
BACKGROUND Previous studies have suggested that fluoroquinolone-resistant strains of Escherichia coli that infect humans probably emerged as a consequence of using fluoroquinolones in poultry. This study aims to provide further insight into the possible avian origin of fluoroquinolone-resistant extraintestinal pathogenic E. coli (ExPEC) strains that infect humans. METHODS We compared the phyl...
