Phylogenetic groups and pathogenicity island markers in fecal Escherichia coli isolates from asymptomatic humans in China.
The study of phylogenetic groups and pathogenicity island (PAI) markers in commensal Escherichia coli strains from asymptomatic Chinese people showed that group A strains are the most common and that nearly half of all fecal strains which were randomly selected harbor PAIs.

متن کاملDistribution of pathogenicity island (PAI) markers and phylogenetic groups in diarrheagenic and commensal Escherichia coli from young children
AIM This case-control study investigated the various PAI markers, phylogenetic groups and antimicrobial susceptibility among DEC and commensal E. coli isolates. BACKGROUND Diarrheagenic Escherichia coli (DEC) is an emerging agent among pathogens that cause diarrheal diseases and represents a major public health problem in developing countries. The major difference in virulence among DEC patho...
متن کاملThe pathogenicity islands (PAIs) of the uropathogenic Escherichia coli strain 536: island probing of PAI II536.
Pathogenicity islands (PAIs) represent distinct pieces of DNA that are present in the genomes of pathogenic bacteria but absent from the genomes of related nonpathogenic strains. They carry (often more than one) virulence genes and are linked to transfer RNA (tRNA) loci. In addition, they carry mobility genes and direct repeats at their ends and are often unstable [1]. The first PAIs have been ...
متن کاملPathogenicity island sequences of pyelonephritogenic Escherichia coli CFT073 are associated with virulent uropathogenic strains.
Urinary tract infection is the most frequently diagnosed kidney and urologic disease, and Escherichia coli is by far the most common etiologic agent. Defined blocks of DNA termed pathogenicity islands have been found in uropathogenic strains to carry genes not generally found in fecal strains. We have identified one of these regions of DNA within the chromosome of the highly virulent E. coli CF...
