Inactivation of highly transmissible livestock and avian viruses including influenza A and Newcastle disease virus for molecular diagnostics. Front Vet Sci 2024; 11:1304022. [PMID: 38515532 PMCID: PMC10955088 DOI: 10.3389/fvets.2024.1304022] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/29/2023] [Accepted: 02/06/2024] [Indexed: 03/23/2024] Open
Abstract
There is a critical need for an inactivation method that completely inactivates pathogens at the time of sample collection while maintaining the nucleic acid quality required for diagnostic PCR testing. This inactivation method is required to alleviate concerns about transmission potential, minimize shipping complications and cost, and enable testing in lower containment laboratories, thereby enhancing disease diagnostics through improved turn-around time. This study evaluated a panel of 10 surrogate viruses that represent highly pathogenic animal diseases. These results showed that a commercial PrimeStore® molecular transport media (PSMTM) completely inactivated all viruses tested by >99.99%, as determined by infectivity and serial passage assays. However, the detection of viral nucleic acid by qRT-PCR was comparable in PSMTM and control-treated conditions. These results were consistent when viruses were evaluated in the presence of biological material such as sera and cloacal swabs to mimic diagnostic sample conditions for non-avian and avian viruses, respectively. The results of this study may be utilized by diagnostic testing laboratories for highly pathogenic agents affecting animal and human populations. These results may be used to revise guidance for select agent diagnostic testing and the shipment of infectious substances.

Front Vet Sci 2021; 8:665128. [PMID: 34055953 PMCID: PMC8160231 DOI: 10.3389/fvets.2021.665128] [Citation(s) in RCA: 27] [Impact Index Per Article: 9.0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/07/2021] [Accepted: 04/16/2021] [Indexed: 12/20/2022] Open
Abstract
The bovine viral diarrhea virus (BVDV) consists of two species and various subspecies of closely related viruses of varying antigenicity, cytopathology, and virulence-induced pathogenesis. Despite the great ongoing efforts to control and prevent BVDV outbreaks and the emergence of new variants, outbreaks still reported throughout the world. In this review, we are focusing on the molecular biology of BVDV, its molecular pathogenesis, and the immune response of the host against the viral infection. Special attention was paid to discuss some immune evasion strategies adopted by the BVDV to hijack the host immune system to ensure the success of virus replication. Vaccination is one of the main strategies for prophylaxis and contributes to the control and eradication of many viral diseases including BVDV. We discussed the recent advances of various types of currently available classical and modern BVDV vaccines. However, with the emergence of new strains and variants of the virus, it is urgent to find some other novel targets for BVDV vaccines that may overcome the drawbacks of some of the currently used vaccines. Effective vaccination strategy mainly based on the preparation of vaccines from the homologous circulating strains. The BVDV-E2 protein plays important role in viral infection and pathogenesis. We mapped some important potential neutralizing epitopes among some BVDV genomes especially the E2 protein. These novel epitopes could be promising targets against the currently circulating strains of BVDV. More research is needed to further explore the actual roles of these epitopes as novel targets for the development of novel vaccines against BVDV. These potential vaccines may contribute to the global eradication campaign of the BVDV.

Abstract
A high-passage rabbit kidney RK-13 cell line (HP-RK-13[KY], originally derived from the ATCC CCL-37 cell line) used in certain laboratories worldwide is contaminated with noncytopathic bovine viral diarrhea virus (ncpBVDV). On complete genome sequence analysis, the virus strain was found to belong to BVDV group 1b.

Analysis of a pair of END+ and END- viruses derived from the same bovine viral diarrhea virus stock reveals the amino acid determinants in Npro responsible for inhibition of type I interferon production.

Abstract
The Exaltation of Newcastle disease virus (END) phenomenon is induced by the
inhibition of type I interferon in pestivirus-infected cells in vitro,
via proteasomal degradation of cellular interferon regulatory factor (IRF)-3 with the
property of the viral autoprotease protein Npro. Reportedly, the amino acid
residues in the zinc-binding TRASH motif of Npro determine the difference in
characteristics between END-phenomenon-positive (END+) and
END-phenomenon-negative (END−) classical swine fever viruses (CSFVs). However,
the basic mechanism underlying this function in bovine viral diarrhea virus (BVDV) has not
been elucidated from the genomic differences between END+ and END−
viruses using reverse genetics till date. In the present study, comparison of complete
genome sequences of a pair of END+ and END− viruses isolated from
the same virus stock revealed that there were only four amino acid substitutions (D136G,
I2623V, D3148G and D3502Y) between two viruses. Based on these differences, viruses with
and without mutations at these positions were generated using reverse genetics. The END
assay, measurements of induced type I interferon and IRF-3 detection in cells infected
with these viruses revealed that the aspartic acid at position 136 in the zinc-binding
TRASH motif of Npro was required to inhibit the production of type I interferon
via the degradation of cellular IRF-3, consistently with CSFV.

Abstract
Field isolates of BVDV which do not show the exaltation of Newcastle disease virus (END)
phenomenon (END–) are rarely reported. In this study, 45 BVDV field isolates
from cattle in Hokkaido prefecture in Japan were analyzed by the reverse plaque formation
method, the END method and observation of cytopathic effects. END– virus was
detected in 34 of 45 isolates (75.6%), although 35 of 45 field isolates contained END
phenomenon positive virus as the predominant virus population. We propose that
END– viruses are widely distributed in the field and that it is possible that
the mixture of biologically distinct BVDV correlates with the appearance of disease in
infected animals.
