Newcastle disease Virus (NDV-U) Nucleic Acid Test Kit (Lyophilized)

The Newcastle Disease Virus Universal (NDV - U) Nucleic Acid Detection Reagent is a specialized diagnostic tool developed for the rapid and accurate detection of Newcastle Disease Virus (NDV). NDV is a member of the Avulavirus genus within the Paramyxoviridae family. It is a highly contagious virus that affects a wide range of avian species, including chickens, ducks, turkeys, and wild birds. Newcastle disease can cause severe respiratory, nervous, and digestive system disorders in poultry, leading to high mortality rates and significant economic losses in the poultry industry.

Clinical Applications

1. Poultry Farm Surveillance：In commercial poultry farms, regular screening of poultry is crucial for early detection of NDV. By collecting samples such as tracheal swabs, cloacal swabs, or tissue samples from chickens, ducks, and turkeys at regular intervals (e.g., monthly or quarterly), farmers and veterinarians can identify the presence of the virus in a timely manner. For example, in a large - scale chicken farm with thousands of birds, routine sampling and testing using the NDV - U nucleic acid detection reagent can help detect the virus in its early stages. Once detected, immediate isolation of infected birds, enhanced biosecurity measures, and possible culling of affected flocks can be implemented to prevent the spread of the virus within the farm.

2. Disease Diagnosis in Poultry：When poultry show symptoms such as respiratory distress, coughing, sneezing, nervous disorders (such as tremors, abnormal gait), decreased egg production, or sudden death, the NDV - U nucleic acid detection reagent serves as a vital diagnostic tool. It allows for a quick and accurate determination of whether NDV is the causative agent. In a duck - farming operation where ducks show signs of respiratory illness and some have abnormal behavior, using this reagent to test the samples can quickly confirm the presence or absence of NDV. This timely diagnosis is essential for implementing appropriate treatment and control measures, such as providing supportive care for the sick birds and strengthening biosecurity protocols to protect the remaining healthy flock.

3. Wild Bird Monitoring：Wild birds play a significant role in the natural transmission of NDV. The NDV - U nucleic acid detection reagent is used to test samples from wild birds in areas where they congregate, such as wetlands, lakes, and bird - nesting sites. Monitoring wild bird populations can help in early detection of NDV and predict potential spill - over events to domestic poultry. For instance, during the spring and autumn migrations, samples from dead or sick wild birds are collected and tested. If NDV is detected in wild birds in a particular region, it can trigger increased surveillance and preventive measures in nearby poultry farms to safeguard the domestic poultry industry.

4. Quarantine and Import/Export Control：In international trade of poultry and poultry products, the NDV - U nucleic acid detection reagent is an essential component of quarantine procedures. All incoming and outgoing poultry, hatching eggs, and processed poultry products are screened to prevent the international spread of NDV. If a positive sample is detected in imported or exported items, 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 nations and protecting their domestic poultry industries from foreign - sourced NDV infections.
