These patients have been considered to be less responsive to interferon-based therapies and represent a therapeutic challenge due to reciprocal viral interference.8 It appears that high levels of HBV-deoxyribonucleic acid (DNA) contributes to chronic liver damage and development of cirrhosis in HCV-infected patients.11 Therefore, it is important to determine a relation between pre-treatment variables and its effect on interferon therapy in HCV/HBV co-infected patients.
Whilst the UK grid, by virtue of excellence in fundamental design, and power system hardware of the best quality, and, arguably, has the highest reliability of any grid system in the world, its control depends almost entirely on information technology systems and software which is not, and cannot be, entirely invulnerable to viral interference.
Besides the antigenic variation, other factors can interfere on efficacy of a vicinal program, among them, the viral interference. This phenomenon can occur among different serotypes of the same virus, for example IBDV with intermediate and pathogenic strains [21] and it can also occur between different viruses, as between infectious bronchitis virus (IBV) and Newcastle disease virus (NDV) [22] or avian pneumovirus [23].Therefore, the major purpose of this investigation is to study the immunosuppressive effects of IBD vaccines schedule being used in Pakistan on the ND vaccine.

He believes rhinovirus may have blocked the spread of swine flu via a process called viral interference.
The lowest sample dilution that could be evaluated without significant cytotoxicity or viral interference was 1:3 for PRY, 1:30 for XMuLV, 1:300 for BVDV, and 1:300 for BPV These results were used to perform appropriate dilutions on the spiked thrombin load samples in order to eliminate any potential for cytotoxicity and viral interference with the assay.
