Abstract:
:The infectious entry pathway of duck hepatitis B virus (DHBV) was investigated with primary duck hepatocytes. Virus uptake was measured by a selective PCR technique which allows for the detection of a successful infection without the need for viral replication or gene expression. To test whether DHBV uptake occurs by endocytosis, the effects of energy depletion were analyzed. The requirement for an acidic intracellular pH was tested with the lysosomotropic agent ammonium chloride. The data show that energy depletion prevents the uptake of DHBV into primary hepatocytes whereas ammonium chloride has no effect. From these data, we conclude that DHBV is taken up by its host cells by endocytosis. However, in contrast to that of most other enveloped viruses, escape of DHBV from the endocytotic route does not depend on an acidic intracellular compartment.
