Preclinical Service for Orf Virus (Sore Mouth Infection) Therapeutic Development &Diagnostic Advancement

Overview

The Orf virus (ORFV) is part of the Poxviridae family and features a large double-stranded DNA genome that extends for about 140 kilobases and includes 132 genes. The virus genome features stable central regions required for replication and morphogenesis, and its terminal regions exhibit variation that contributes to virulence and immune evasion. The ORFV virus leads to contagious eczema known as Orf, which mostly infects sheep and goats but also shows zoonotic potential for human infection. While Orf typically remains harmless, Orf develops into a serious condition for young animals, which leads to economic difficulties in livestock farming. ORFV displays diverse strain variations that enable it to infect hosts repeatedly. The virus deploys multiple immune evasion mechanisms, which involve producing anti-inflammatory proteins while it suppresses interferon-stimulated gene expression and modifies JAK/STAT signaling pathways. The virus affects apoptotic pathways to prevent immune system elimination and attracts increasing attention from immunological researchers. Creative Biolabs offers full preclinical research services for virus studies through viral vector development and recombinant protein production, along with antibody generation, as well as in vitro and in vivo efficacy tests and immunological assays. Our organization offers specialized, high-quality solutions to expedite research for vaccine development as well as diagnostic and antiviral drug creation.

Accelerated ORFV (Sore Mouth Infection) Preclinical Research Services (Therapeutics & Diagnostics)

• For Therapeutics Development

In Vitro Antiviral Efficacy Assays

• Cytotoxicity assays: Potential antiviral drugs require toxicity evaluation using host cell assays like MTT and LDH.
• Viral replication inhibition: Researchers tested how compounds affect viral replication through different stages, including entry and assembly.
• Viral load measurement: We measure viral quantities in cell cultures that received treatment as well as untreated ones through PCR analysis or viral titer assays.
• Immunofluorescence assays: Immunofluorescence assays serve to detect viral antigens or protein expression within infected cells while testing candidate interference with viral replication.
• Plaque reduction assay: The test evaluates how well a candidate can decrease the formation of viral plaques across a layer of cells.

In Vivo Efficacy Studies (Animal Models)

• Efficacy studies: The study tracks how the candidate treatment affects viral load reduction, lesion size diminution, and survival rates in animal models.
• Pharmacokinetics (PK) studies: The pharmacokinetics study involves measuring how the therapeutic drug moves through the body by observing its absorption, distribution, metabolism, and excretion (ADME).
• Toxicity studies: The research focuses on examining safety concerns and possible adverse effects of the therapeutic agent during animal testing.
• Immunological response: Evaluate the treatment-induced immune response through antibody production and cytokine profiles to understand its effectiveness against the virus.
• Pathological analysis: Researchers analyze tissue samples to detect indications of inflammation, along with viral load and tissue damage.

• For Diagnostics Development

Antigen Detection Assays

• Antigen-based ELISA: The test identifies precise viral antigens, including proteins such as B2L and other structural viral proteins.
• Immunofluorescence Assay (IFA): The assay identifies viral antigens present in infected cells by employing antibodies that have been tagged with fluorescent markers.
• Rapid Diagnostic Tests (RDTs): LFAs are specifically created for use at the point-of-care or in field conditions.
• Western Blotting: This method detects specific viral antigens present in tissue or blood samples from infected hosts.

Nucleic Acid Detection Assays

• Real-time PCR (qPCR): Real-time PCR (qPCR) represents the definitive method for measuring viral DNA levels in clinical specimens.
• RT-PCR: The RT-PCR method normally applies to RNA virus research but can help detect viral RNA produced during active replication cycles of DNA viruses such as Orf.
• The ddPCR technique is a quantitative PCR method that achieves high sensitivity through the division of samples into thousands of droplets before DNA amplification in each one.
• Whole Genome Sequencing: NGS is a technique that enables researchers to sequence the complete Orf virus genome to analyze the specific strain and identify any genetic mutations.

Antibody Detection Assays (Serology)

• IgM/IgG ELISA: The serological test identifies recent infection through IgM antibodies and past infection or immunity through IgG antibodies.
• Western Blotting: This technique identifies antibodies specific to Orf virus proteins present in serum or plasma samples.
• IFA for antibody detection: The assay is versatile enough to measure specific IgM/IgG antibodies found in patient serum samples.
