Citation style for this article: Jansen A, Kielstein JT. The new face of enterohaemorrhagic Escherichia coli infections. The unprecedented outbreak of Shiga toxin/vero-toxin-producing Escherichia coli (STEC/VTEC) O104:H4 in Germany in May and June 2011 displayed several novel epidemiological, microbiological and clinical features. Infection with STEC/VTEC, also referred to as enterohaemorrhagic...
Population-based surveillance for Vero cytotoxin-producing Escherichia coli (VTEC) O157 has been carried out in Wales since 1990. The annual incidence has remained stable during the 9-year period (mean: 1.6 cases per 100,000 population); the rate is highest in children younger than 5 years of age. Blood in the stool is reported in fewer than half the cases, indicating the importance of screenin...
prevalence of verotoxin-producing escherichia coli (vtec) in a survey of dairy cattle in najaf, iraq
background and objectives: dairy cattle have been implicated as principal reservoir of verotoxin-producing escherichia coli (vtec), with undercooked ground beef and raw milk being the major vehicles of food borne outbreaks. vtec has been implicated as an etiological agent of individual cases and outbreaks in developed countries. this study was designed to determine the prevalence of vetec in di...
Diarrhea is an important hygienic problem in under development countries. Among pathogenic agents Escherichia coli is the most etiologic agent of diarrhea in children below five years old. Some E. coli strains produce cytotoxins that have cytopathic effect on vero cell and identified as verotoxin. This study performs for resolve frequency of Vero Toxigenic Escherichia coli...
مقاله حاضر در راستای کشف وجود یا عدم وجود رابطه تحولات پارامترهای یون‌سپهری با پدیده هواشناختی بارش، تغییرات بیشینه‌های روزانه محتوای کلی الکترونی قائم (VTEC) یون‌سپهری حاصل از پردازش داده‌های خام دو ایستگاه GPS را با تغییرات بارش ثبت شده در دو ایستگاه همدیدی واقع در محل ایستگاه‌های GPS، که در بازه زمانی مورد بررسی از نظر میزان بارش تفاوت قابل توجهی داشتند، مورد تحلیل و مقایسه قرار داده است. ای...
In the summer of 2009, an outbreak of verocytotoxigenic Escherichia coli O157 (VTEC O157) was identified in visitors to a large petting farm in South East England. The peak attack rate was 6/1000 visitors, and highest in those aged <2 years (16/1000). We conducted a case-control study with associated microbiological investigations, on human, animal and environmental samples. We identified 93 ca...
در سال های اخیر در برخی نقاط جهان رابطه پدیده های هواشناختی به خصوص چرخندهای حاره ای با یون سپهر، به طرق گوناگون مورد مطالعه قرار گرفته است. این مقاله نیز در راستای کشف وجود یا عدم وجود رابطه یون سپهر با پدیده هواشناختی بارش، تغییرات بیشینه های محتوای کلی الکترونی قائم (vtec) یون سپهری حاصل از پردازش داده های دو ایستگاه gps را، در شرایط آرام ژئومغناطیسی، با تغییرات بارش ثبت شده در دو ایستگاه هم...
diarrhea is an important hygienic problem in under development countries. among pathogenic agents escherichia coli is the most etiologic agent of diarrhea in children below five years old. some e. coli strains produce cytotoxins that have cytopathic effect on vero cell and identified as verotoxin. this study performs for resolve frequency of vero toxigenic escherichia coli (vtec) in kerman city...
reduced rainfall in many parts of the world have prompted scientists to try to manipulate, in different ways, to the nature, causing precipitation from accumulated water in the atmosphere. atmospheric ionization is a new method for producing precipitation and has attracted much attention. in this regard, in recent years, in some regions of the world, in different ways, the relation between mete...
This study analyses the relationship between meteorological phenomena and outbreaks of waterborne-transmitted vero cytotoxin-producing Escherichia coli (VTEC) in the Republic of Ireland over an 8-year period (2005-2012). Data pertaining to the notification of waterborne VTEC outbreaks were extracted from the Computerised Infectious Disease Reporting system, which is administered through the nat...
