Development and assessment of a rapid method to detect Escherichia coli O26, O111 and O157 in retail minced beef.
A molecular-based detection method was developed to detect Escherichia coli O26, O111 and O157 in minced (ground) beef samples. This method consists of an initial overnight enrichment in modified tryptone soya broth (mTSB) and novobiocin prior to DNA extraction and subsequent serogrouping using a triplex PCR. This method has a low limit of detection and results are available within 24 hours of ...
متن کاملValidation of a method for simultaneous isolation of Shiga toxin-producing Escherichia coli O26, O103, O111, and O145 from minced beef by an international ring-trial.
An isolation method described by Possé et al. (FEMS Microbiol Lett 2008;282:124-131) was satisfactorily validated in an international ring-trial using artificially contaminated minced beef samples. Until now, no validated method existed for the simultaneous isolation of Shiga toxin-producing Escherichia coli serogroups O26, O103, O111, and O145 in food. Twelve laboratories from five European co...

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...

Susceptibilities to fourteen antimicrobial agents important in clinical medicine and agriculture were determined for 752 Escherichia coli isolates of serotypes O26, O103, O111, O128, and O145. Strains of these serotypes may cause urinary tract and enteric infections in humans and have been implicated in infections with Shiga toxin-producing E. coli (STEC). Approximately 50% of the 137 isolates ...
متن کاملAntimicrobial resistance of Escherichia coli O26 and O111 isolates from cattle and their characteristics.
The present study was to investigate antimicrobial resistance profiles of Escherichia coli O26 and O111 from cattle and to characterize the virulence genes of the resistant isolates. This paper reports the high prevalence of antimicrobial resistant E. coli O26 and O111 from cattle. Among 37 E. coli O26 and 25 E. coli O111 isolates from the fecal specimens obtained from cattle, 26 (70%) and 15 (...
