Significats de avian hev en anglès

Avian HEV was recently discovered in chickens with hepatitis-splenomegaly syndrome in the USA.

Antibodies against avian HEV and ALV-J in these serum samples were detected using iELISAs.

This study provides insights for prevention and control of avian HEV infection in chicken flocks.

In this study, we analyzed the effect of caged versus cage-free housing arrangements on avian HEV transmission.

The iELISA was used to evaluate the seroprevalence of avian HEV in poultry farms in the Shandong province.

However, circulating avian HEV was confirmed on these farms using tests to detect avian HEV IgG antibodies and RNA.

This study also provides full genomic data for better understanding the evolutionary relationships of avian HEV circulating in China.

The results indicated that all three cDNA clones of avian HEV are infectious both in vitro and in vivo.

The iELISA that was developed in this study can be used for detection of immunoglobulin G antibodies against avian HEV.

Avian HEV has been identified as the aetiological agent of big liver and spleen disease or hepatitis-splenomegaly syndrome in chickens.

Altogether, the results presented in this study suggest that more attention should be paid to avian HEV and its potential disease manifestation.

In the study, the seroprevalence of avian HEV and ALV-J in these flocks emerging the disease from Shandong and Shaanxi provinces were investigated.

Conclusions: These results suggest that reduction of contact with feces as seen in the caged arrangement of housing chickens can reduce avian HEV transmission.

Therefore, the experimental and field data indicate that avian HEV infection acting alone could account for observed decreases in egg production in laying hens.

The objective of this study was to construct and characterize an infectious cDNA clone of avian HEV for future studies of HEV replication and pathogenesis.
