    Summary Infectious pancreatic necrosis virus (IPNV) attaches to CHSE-214 cells through two types of cell components: specific and non-specific ones. Competition experiments with inactivated IPNV showed that IPNV requires specific components to productively infect cells. Just a low amount of adsorbed IPNV enters the cell. After 20 minutes, part of the adsorbed IPNV was internalized into acid compartments. Also, the viruses adsorbed on the cell surface require similar periods of time to escape from the neutralization of antibodies.

    Summary.  The temporal subcellular localization of the structural proteins VP2 and VP3 of infectious pancreatic necrosis virus was analyzed with monoclonal antibodies conjugated with fluorochromes. Early in the infection both proteins were colocalized in the cytosol, at later times, VP2 was visualized as inclusion bodies around the nuclei of the cells and, sometimes, it was found in elongated tubular structures that might correspond to the type I tubules seen in cells infected with another Birnavirus. As VP2 is a glycosylated protein we determined its subcellular localization compared with that of ER and Golgi probes. These results suggest that VP2 is glycosylated freely in the cytoplasm.

    Summary.  The early events in the infection of unenveloped viruses are still rather unknown and puzzling. However, as in the case of enveloped viruses, the acid pH of endosomes can be important to trigger the virus entry into the cytosol. To test if the infectious pancreatic necrosis virus (IPNV), an unenveloped virus, requires acid endosomal pH to infect cells, we assayed the effect of Bafilomycin A1 on IPNV replication. Concentrations of the antibiotic which inhibited the endosomal acidification of the host cells were unable to affect IPNV replication in CHSE-214 cells; therefore, the acid pH of endosomes seems not to be a mandatory condition for the entry of IPNV into cells.
