Chicken Infectious Laryngotracheitis Virus (AILTV) Nucleic Acid Test Kit (Lyophilized)

Avian Infectious Laryngotracheitis Virus (AILTV), belonging to the family Herpesviridae, is a highly contagious pathogen that severely affects the poultry industry. It primarily targets the upper respiratory tract of chickens, causing significant damage to the tracheal mucosa. The symptoms of AILTV infection are quite distinct. Infected chickens typically experience severe respiratory distress, characterized by gasping, coughing, and the production of bloody mucus. This can lead to a high mortality rate, especially in severe cases. Additionally, the disease can cause a sharp decline in egg production in laying hens, resulting in substantial economic losses for poultry farmers.

Clinical Applications

1. Poultry Farm Surveillance：In commercial poultry farms, regular screening using the AILTV nucleic acid detection reagent is crucial for early detection of the virus. By collecting samples from chickens at regular intervals (e.g., every 1 - 2 weeks), farmers and veterinarians can identify the presence of AILTV in a timely manner. For example, in a large - scale broiler chicken farm, samples are collected from different chicken houses. If AILTV is detected in a particular area, immediate isolation of the infected birds can be carried out, and enhanced biosecurity measures can be implemented. This includes strict disinfection of the poultry houses, proper ventilation improvement, and restricted movement of personnel and equipment to prevent further spread within the farm.

2. Disease Diagnosis in Poultry：When chickens show symptoms of severe respiratory distress, such as gasping, coughing up blood - tinged mucus, or a sudden drop in egg production in laying hens, the AILTV nucleic acid detection reagent serves as a vital diagnostic tool. It allows for a quick and accurate determination of whether AILTV is the causative agent. In a layer chicken farm where some hens are experiencing these symptoms, using this reagent to test the samples can quickly confirm the presence or absence of AILTV. This timely diagnosis is essential for implementing appropriate treatment and control measures. Although there is no specific antiviral treatment for AILTV, supportive care can be provided to the sick birds, such as humidifying the air to ease breathing difficulties. Measures can also be taken to prevent the spread of the virus to the remaining healthy flock.

3. Vaccine Efficacy Monitoring：In poultry farms that have implemented AILTV vaccination programs, the detection reagent plays a crucial role in monitoring vaccine efficacy. Periodically testing vaccinated chickens can help determine if the vaccine has effectively induced an immune response and reduced the viral load. If vaccinated birds still test positive for AILTV or show a high viral load, it may indicate vaccine failure or exposure to a highly - virulent strain of the virus. This information can guide farmers to adjust their vaccination strategies, such as changing the vaccine type or the vaccination schedule.

4. Quarantine and Import/Export Control：In international trade of poultry and poultry products, the AILTV 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 AILTV. If a positive sample is detected in imported or exported items, the relevant products can be detained, and further testing or treatment can be carried out 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 AILTV infections.
