Studies on the immunopathologic mechanisms of intestinal lesion formation in turkey poults infected with hemorrhagic enteritis virus
… and immunopathologic mechanisms through which hemorrhagic enteritis virus (HEV) induces intestinal lesion formation associated with clinical infection is unknown. These studies were designed to 1) determine differences in age susceptibility to HEV infection and parameters which best indicate …

Real Time PCR-Based Infectivity Assay and Characterization of Cell Surface Receptors for Turkey Hemorrhagic Enteritis Virus
Turkey hemorrhagic enteritis virus (THEV) is responsible for the hemorrhagic enteritis (HE) disease in commercial turkeys through infections by its virulent strains. HE is an acute condition characterized by depression, immunosuppression, bloody droppings, intestinal hemorrhage, and death. THEV …

The Effect of Social Stress and Vitamin C on Immunity and Response to Hemorrhagic Enteritis Virus in Turkeys
Hemorrhagic Enteritis (HE) vaccine is perhaps the most commonly used vaccine in the turkey industry. Although it provides protection against clinical disease, the vaccine is still thought to produce transient immunosuppression. In the field, HE still remains a significant concern for turkey …

The use of transgenic tobacco as a production and delivery system for a vaccine against hemorrhagic enteritis virus of turkeys
Hemorrhagic enteritis virus (HEV) causes an acute viral disease in turkeys characterized by bloody diarrhea and death. Current live HEV virus vaccines are immunosuppressive and predispose turkeys to secondary bacterial infections. Data indicates that the capsid proteins (fiber, penton base, hexon) …

Characterization of Avirulent Turkey Hemorrhagic Enteritis Virus: A Study of the Molecular Basis for Variation in Virulence and the Occurrence of Persistent Infection
Hemorrhagic enteritis is a disease of turkeys caused by virulent strains of Turkey Hemorrhagic Enteritis Virus (THEV) resulting in depression, splenomegaly, intestinal hemorrhage, immunosuppression, and mortality. Avirulent strains that do not produce intestinal lesions and mortality are used in …

The roles of multiple infectious agents in the predisposition of turkeys to colibacillosis
… through field case studies. They include hemorrhagic enteritis (HE) virus, Newcastle disease virus, and Bordetella avium. Further retrospective serologic studies affirmed the role of these primary agents and uncovered the potential involvement of Mycoplasma meleagridis. Trials were …

Molecular characterization of economically important poultry viruses in western Canada
… Reovirus (ARV), Chicken Astrovirus (CAstV), and Hemorrhagic Enteritis Virus (HEV) are important enteric pathogens affecting poultry production around the world. These agents are the causative agents of Viral Arthritis (VA), White Chick Syndrome (WCS), and Hemorrhagic Enteritis (HE), respectively. …

Characterization of Atypical Hemolytic Ornithobacterium rhinotracheale Isolates and Comparison with the Normal Non-Hemolytic Phenotype
… (n=175). Additionally, the seroprevalence for hemorrhagic enteritis virus (vaccine induced), Bordetella avium, and paramyxovirus-1 was 100%, 74.8%, and 6.3% respectively. No significant interactions were detected. The type strain of ORT is characteristically non-hemolytic at least for 96 hours …
