Avian Influenza H7 (AIV-H7) Nucleic Acid Test Kit (Lyophilized)

Clinical Applications

1. Poultry Farm Surveillance and Prevention：For large - scale poultry farms, regular surveillance using the AIV - H7 nucleic acid detection reagent is crucial for early - warning and prevention of virus introduction and spread. By collecting samples such as tracheal and cloacal swabs from poultry at regular intervals, farmers and veterinarians can detect the presence of AIV - H7 in a timely manner. For example, in a turkey - rearing farm, samples are collected weekly from a randomly selected group of turkeys. If AIV - H7 is detected, immediate isolation of the infected birds can be carried out, and enhanced biosecurity measures can be implemented, including strict disinfection of the farm facilities, restricted movement of personnel and vehicles, and possible culling of the affected flocks to prevent further spread within the farm.

2. Disease Diagnosis in Poultry：When poultry exhibit symptoms like respiratory distress, reduced feed intake, abnormal behavior, or a sudden increase in mortality, the AIV - H7 nucleic acid detection reagent serves as a vital diagnostic tool. It allows for a quick and accurate determination of whether the H7 subtype of avian influenza virus is the causative agent. In a duck - farming operation where ducks show signs of coughing, sneezing, and a decrease in egg production, using this reagent to test the samples can quickly confirm the presence or absence of AIV - H7. 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, especially migratory species, play a significant role in the natural transmission of AIV - H7. The detection reagent is used to test samples from wild birds in areas where they gather, such as wetlands, estuaries, and bird - resting sites. Monitoring wild bird populations can help in early detection of AIV - H7 and predict potential spill - over events to domestic poultry. For instance, during the annual migration of waterfowl, samples from dead or sick wild birds are collected and tested. If AIV - H7 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 from potential infections.

4. Quarantine and Import/Export Control：In international trade of poultry and poultry products, the AIV - H7 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 cross - border spread of AIV - H7. 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 enter or leave the country. This helps in maintaining the biosecurity of nations and protecting their domestic poultry industries from foreign - sourced AIV - H7 infections.
