Avian Influenza Universal (AIV-U) Nucleic Acid Test Kit (Lyophilized)

The Avian Influenza Universal (AIV - U) Nucleic Acid Detection Reagent is a vital tool for the rapid and accurate detection of avian influenza virus (AIV). AIV, belonging to the Orthomyxoviridae family, is a highly variable virus with numerous subtypes classified based on the antigenic properties of its surface glycoproteins, hemagglutinin (HA) and neuraminidase (NA). This universality of the reagent lies in its ability to target conserved regions within the AIV genome, enabling the detection of multiple AIV subtypes, including both low - pathogenic and highly - pathogenic strains.

Clinical Applications

1. Epidemic Surveillance：In poultry - rearing areas, including large - scale commercial farms, backyard flocks, and live - bird markets, regular surveillance using the AIV - U Nucleic Acid Detection Reagent is crucial. By collecting samples from a representative number of birds at regular intervals, veterinarians and public health officials can monitor the presence and prevalence of AIV. Early detection of AIV, especially highly - pathogenic strains, can trigger immediate preventive measures. For example, in regions where avian influenza outbreaks are common, weekly or monthly sampling and testing of poultry can help in early identification of virus circulation, enabling the implementation of quarantine measures, enhanced biosecurity protocols, and vaccination strategies if applicable.

2. Disease Diagnosis in Poultry：When poultry exhibit symptoms such as respiratory distress, decreased egg production, sudden death, or abnormal behavior, the AIV - U Nucleic Acid Detection Reagent serves as a rapid diagnostic tool. Prompt diagnosis is essential for effective disease management. By quickly identifying AIV as the causative agent, farmers can take steps to isolate infected birds, cull affected flocks if necessary, and disinfect the farm environment to prevent further spread. For instance, in a chicken farm where a significant number of hens show a sudden drop in egg production and some have respiratory symptoms, the use of this reagent can quickly determine whether AIV is the culprit, allowing for timely intervention.

3. Wild Bird Monitoring：Wild birds, especially migratory waterfowl, are important reservoirs and potential vectors for the spread of AIV. The AIV - U Nucleic Acid Detection Reagent is used to test samples from wild birds during their migration periods or in areas where they congregate. Monitoring wild bird populations helps in understanding the natural circulation of AIV and predicting potential spill - over events to domestic poultry. For example, in wetlands and bird - nesting areas, samples from dead or sick wild birds are collected and tested using this reagent. If AIV is detected, it can prompt increased surveillance in nearby poultry farms and the implementation of preventive measures to protect the domestic poultry industry.

4. Import - Export Quarantine：In international trade of poultry and poultry products, the AIV - U Nucleic Acid Detection Reagent plays a crucial role in quarantine procedures. All incoming and outgoing poultry, hatching eggs, and processed poultry products are screened to prevent the international spread of AIV. If a positive sample is detected, the relevant products can be detained, destroyed, or subjected to further testing and treatment to ensure that the virus does not cross national borders. This helps in maintaining the biosecurity of countries and protecting their domestic poultry industries from foreign - sourced AIV infections.
