| prevalence of hepatitis e virus antibodies in canadian swine herds and identification of a novel variant of swine hepatitis e virus. | swine hepatitis e virus is a newly identified potentially zoonotic virus from pigs of particular concern for possible direct transmission to a human xenotransplant recipient by organ transplantation. in the present study, prevalence of serum antibodies to hepatitis e virus was examined in canadian swine herds. a total of 998 serum samples collected from 6-month-old healthy slaughter hogs were examined by enzyme immunoassay and western blot analysis for antibodies to the recombinant open reading ... | 2001 | 11687465 |
| avian hepatitis e virus in an outbreak of hepatitis--splenomegaly syndrome and fatty liver haemorrhage syndrome in two flaxseed-fed layer flocks in ontario. | two commercial layer chicken flocks that were fed a flax-based diet beginning at 28 weeks of age for the production of omega-3 fatty-acid-enriched eggs experienced increased mortality when the birds reached 37 weeks. the average weekly mortality was 0.34% over a 20-week period, with peak mortality of 0.9% for 1 week. reduced feed consumption, reduced body weight gain and poor peak production were noticed prior to the onset of increased mortality. a total of 245 birds were necropsied and 78% of t ... | 2006 | 16990151 |
| molecular characterization of hepatitis e virus detected in swine farms in the province of quebec. | swine hepatitis e virus (hev) could be a zoonotic agent for hev infection in humans. in canada, approximately 60% of 6-mo-old commercial pigs are seropositive for hev; the prevalence is higher in the provinces of quebec and ontario. a study was set up to evaluate the presence of swine hev in quebec farms and to compare the strains detected in fecal samples with human and swine hev strains reported worldwide. fecal samples were collected randomly from may 2003 to january 2004 from 70 swine farms ... | 2008 | 18214158 |
| preliminary molecular epidemiological investigation of hepatitis e virus sequences from québec, canada. | our study objective was to describe the canadian hepatitis e virus (hev) sequences currently cataloged in genbank from three populations: commercially raised pigs, retail pork, and locally acquired hepatitis e cases, and to interpret the molecular evidence they provide. we searched the genbank for any/all canadian hev sequences from these populations, and identified highly similar matches using the basic local alignment search tool (blast) algorithm, studying sequences of the partial orf2 gene. ... | 2015 | 25555901 |
