Susceptibility of in vitro produced hatched bovine blastocysts to infection with bluetongue virus serotype 8.

10(4.9) TCID50 of the virus resulted in active viral replication in between 25 and 100% of the cells at 72 h post exposure. The infected blastocysts also showed growth arrest as evidenced by lower total ...

Fine quantification of avian influenza H5N1 escape mutant quasispecies populations using mutation-specific real-time PCR.

Analysis, RNA Species Specificity Virus Cultivation Abstract: Influenza viruses have a rapid replication cycle, using enzymes without proofreading capacity and generating multiple virus quasispecies during ...

Development of specific enzyme-linked immunosorbent assays to evaluate the duck immune response after experimental infection with H5N1 and H7N1 low pathogenic avian influenza viruses.

mucosal surface may play an important role not only in protection but also in limitation of the primary replication at the portal of entry and shedding of the virus. With this aim, specific enzyme-linked ...

The reduction of CSFV transmission to untreated pigs by the pestivirus inhibitor BPIP: a proof of concept.
