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 dia...

متن کاملPrevalence and molecular characterization of verotoxin-producing Escherichia coli O157:H7 in cattle and sheep in Shiraz-Iran
Shiga toxin producing Escherichia coli have been associated with HUS, HC and TTP in human. We found recto-anal mucosal sample in sheep as well in cattle is the main site for E. coli O157 localization. 1246 E. coli isolates from 872 both healthy and diarrheic animals were analyzed, by screening for the presence of Shiga toxin-producing (VT 1 and VT 2) and intimin (eae) genes used Multiplex PCR. ...
متن کاملFactors associated with fecal shedding of verotoxin-producing Escherichia coli O157 on dairy farms.
Fecal samples were collected from 4,361 dairy cows on 91 dairy operations between 26 February and 8 July 1996. Fecal samples were cultured for Escherichia coli O157, and positive isolates were probed for verotoxin-producing genes. A total of 52 (1.2%) fecal samples on 22 (24.2%) operations were positive for verotoxin-producing E. coli O157. Herds in which samples were collected on or after 1 Ma...
متن کاملDetection and prevalence of verotoxin-producing Escherichia coli O157 and non-O157 serotypes in a Canadian watershed.
Verotoxin-producing Escherichia coli (VTEC) strains are the cause of food-borne and waterborne illnesses around the world. Traditionally, surveillance of the human population as well as the environment has focused on the detection of E. coli O157:H7. Recently, increasing recognition of non-O157 VTEC strains as human pathogens and the German O104:H4 food-borne outbreak have illustrated the impor...
