Integrated Preclinical Research Service for Quailpox Virus Therapeutics & Diagnostics

Overview

The Quailpox virus (QPXV) belongs to the Avipoxvirus genus within the Poxviridae family and mainly targets quail birds, along with other types of game birds. Quailpox presents as a contagious disease featuring both cutaneous and diphtheritic lesions. The cutaneous form appears as nodular lesions on unfeathered areas like the beak and eyelids, while the diphtheritic form impacts the mouth and upper respiratory tract, leading to respiratory distress and possible death. Infected birds transmit the disease through physical interaction, and mechanical vectors like mosquitoes and mites carry the infection. Wild and domesticated quail populations face severe risks from quailpox virus because it decreases growth rates and feed efficiency while increasing death rates. Host-specific virus outbreaks still affect both game bird industries and the populations of ecological birds. The diagnostic process for Quailpox virus includes clinical observation in conjunction with histopathology examination and both virus isolation and PCR methodologies. Creative Biolabs provides complete preclinical research services for Quailpox virus that include in vitro antiviral screening, along with vaccine development and in vivo efficacy and safety studies using suitable avian models. Our team provides expertise in virology, immunology, and pathology, which supports your R&D pipeline starting from early discovery phases through IND-enabling studies. Our dedication to scientific excellence and regulatory compliance enables us to provide high-quality data that boosts the progress of your infectious disease research initiatives.

Accelerated Quailpox Virus Preclinical Research Services

• For Therapeutics Development

In Vitro Antiviral Efficacy Assays

• Cytotoxicity Screening: Tests to determine the potential toxicity of the drug candidate in cultured cells, ensuring it doesn't harm normal cells while targeting the virus.
• Viral Replication Inhibition Assays: Measuring the ability of a drug to reduce the replication of Quailpox virus in infected cell lines.
• EC50/IC50 Determination: Determines the effective concentration of the therapeutic required to inhibit viral replication by 50%, a key indicator of the drug's potency.
• Time-of-Addition Assays: Studies to identify at which stage of the viral lifecycle the therapeutic acts (e.g., entry, replication, or release stages).
• Mechanism of Action (MOA) Studies: Detailed analysis of how the drug impacts the viral life cycle (e.g., viral entry inhibition, protease inhibition, or RNA interference).

In Vivo Efficacy Studies (Animal Models)

• Animal Model Selection: Using appropriate models, often small mammals like mice or rabbits, to assess drug efficacy.
• Viral Load Monitoring: Measuring the viral load in the animal after drug treatment. Blood or tissue samples are collected to evaluate the extent of viral infection in organs and tissues.
• Dose-Response Studies: Establishing the optimal therapeutic dose for the drug by testing multiple doses in the animal model.
• Survival Studies: Tracking the survival rate of animals treated with the drug compared to untreated controls, which is a fundamental endpoint for antiviral efficacy.
• Histopathology Studies: Examining tissues from infected animals to assess the degree of virus-induced pathology (e.g., tissue damage, inflammation) and the impact of treatment.

• For Diagnostics Development

Antigen Detection Assays

• Enzyme-Linked Immunosorbent Assay (ELISA): This is commonly used to detect QPXV antigens in infected tissues or fluids. It involves using antibodies specific to viral proteins that can bind and produce a measurable signal.
• Immunohistochemistry (IHC): Tissue samples from infected animals are processed to detect viral antigens using labeled antibodies.
• Lateral Flow Assays: These rapid tests can be used to detect QPXV antigens in samples like blood, saliva, or nasal swabs.
• Western Blotting: This technique identifies specific QPXV proteins in a sample based on molecular weight and antibody recognition, providing detailed information about viral proteins present.

Nucleic Acid Detection Assays

• Real-Time PCR (qPCR): A more advanced version of PCR that allows for quantitative detection of QPXV RNA or DNA in a sample.
• Nested PCR: This is a variant of PCR used for detecting low levels of viral DNA/RNA. It involves two rounds of amplification, improving sensitivity for samples with minimal viral presence.
• In Situ Hybridization (ISH): This method uses labeled nucleic acid probes to detect specific viral RNA or DNA sequences within tissue samples, allowing for precise localization of viral genetic material in tissues.
• Loop-Mediated Isothermal Amplification (LAMP): A more recent technique for nucleic acid amplification that works at a constant temperature and provides rapid detection of viral nucleic acids, useful for field diagnostics.

Antibody Detection Assays (Serology)

• Western Blotting for Antibodies: This can be used to confirm the presence of antibodies against specific QPXV proteins.
• Indirect Immunofluorescence Assay (IFA): This technique involves the use of fluorescently-labeled antibodies that bind to host antibodies specific to QPXV.
• Neutralization Assays: These tests measure the ability of antibodies in the serum to neutralize the virus, providing a more functional measure of immune response.
• Virus Neutralization Test (VNT): This assay involves mixing animal or human serum with live QPXV and observing whether the serum can prevent viral replication in cell cultures.
