Reducing the public health risk of Escherichia coli O157 exposure by immunization of cattle.
The One Health approach investigates the complexities surrounding the interplay between the animal, human and environmental domains. Zoonotic pathogens, such as Escherichia coli (E. coli) O157, which have animal reservoirs, also have direct impact on public health. Cattle are the primary reservoir of E. coli O157, however infection with this bacterium is asymptomatic. Infected cattle appear hea...
متن کاملPredicting the public health benefit of vaccinating cattle against Escherichia coli O157.
Identifying the major sources of risk in disease transmission is key to designing effective controls. However, understanding of transmission dynamics across species boundaries is typically poor, making the design and evaluation of controls particularly challenging for zoonotic pathogens. One such global pathogen is Escherichia coli O157, which causes a serious and sometimes fatal gastrointestin...
متن کاملDraft risk assessment of the public health impact of Escherichia coli O157:H7 in ground beef.
An assessment of the risk of illness associated with Escherichia coli O157:H7 in ground beef was drafted in 2001. The exposure assessment considers farm, slaughter, and preparation factors that influence the likelihood of humans consuming ground beef servings containing E. coli O157:H7 and the number of cells in a contaminated serving. Apparent seasonal differences in prevalence of cattle infec...
متن کاملThe Importance of Escherichia coli O157:H7 in Foodborn Infection
Enterohemorrhagic Escherichia coli O157: H7 is one of the most important causes of bloody diarrhea. This bacterium is able to make bloody diarrhea or Hemorrhagic Colitis (HC) through verotoxin or shigatoxin production, and in acute forms it may lead to Hemolytic Uremic Syndrome (HUS) or Thrombotic Thrombocytopenic Purpurea (TTP). Contamination with E. coli O157:H7 usually happens after consumpt...
متن کاملPCR detection of Escherichia coli O157:H7 directed from slaughtered cattle in Shiraz, Iran
Escheric hia coli O157:H7 lives in the intestines of healthy cattle, and can contaminate meat during slaughtering pr actices . Detection of the low infectious dosage of bacterium requires a sensitive method. We developed polymerase chain reaction (PCR) assays to detect the gene Stx2 irrespective of the bacterial serotype. In this study, the detection limit of the PCR protocol in detecting Stx...
