Distribution 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...

results we found a high number of pai markers such as pai icft073, pai iicft073, pai i536, pai iv536, pai ii j96 and pai ii536 significantly associated with upec. the pai iv536 was the most detected ones among fecal e. coli isolated from healthy people while pai i536, pai ii536 and pai ij96 were not seen. pcr phylogenetic groups typing revealed that uropathogenic strains were mainly found in b2...
متن کاملPhylogenetic 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.

پس ازفروپاشی شوروی،رشد منابع نفت و گاز، آسیای میانه و قفقاز را در یک بازی ژئوپلتیکی انرژی قرار داده است. با در نظر گرفتن این منابع هیدروکربنی، این منطقه به یک میدانجنگ و رقابت تجاری برای بازی های ژئوپلتیکی قدرت های بزرگ جهانی تبدیل شده است. روسیه منطقه را به عنوان حیات خلوت خود تلقی نموده و علاقمند به حفظ حضورش می باشد تا همانند گذشته گاز طبیعی را به وسیله خط لوله مرکزی دریافت و به عنوان یک واس...
15 صفحه اولThe 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 کاملLongitudinal Comparison of Antibiotic Resistance in Diarrheagenic and Non-pathogenic Escherichia coli from Young Tanzanian Children
Enteroaggregative, enteropathogenic, and enterotoxigenic Escherichia coli contribute significantly to the burden of diarrheal infections particularly in developing countries. Antibiotic resistance is increasingly common among bacterial pathogens including pathogenic E. coli. We assessed the relationship between pathogenic E. coli carriage and resistance to six antibiotics in E. coli isolated fr...
