Chicken Infectious Bursal Virus (IBDV) Nucleic Acid Test Kit (Lyophilized)

Infectious Bursal Disease Virus (IBDV) is a highly contagious pathogen that has a significant impact on the poultry industry, especially in young chickens. It belongs to the family Birnaviridae. The virus primarily targets the bursa of Fabricius, an important immune organ in chickens. Infected chickens often show a series of symptoms. Acute cases are characterized by sudden onset, with chickens experiencing depression, ruffled feathers, anorexia, and diarrhea. The bursa of Fabricius becomes swollen, hemorrhagic, and may later atrophy, leading to immunosuppression. This immunosuppression makes the chickens more susceptible to other infections, resulting in increased mortality rates and reduced growth performance. Economic losses are substantial, including costs associated with treatment, culling, and decreased productivity.

Clinical Applications

1. Poultry Farm Surveillance：In commercial poultry farms, regular screening using the IBDV nucleic acid detection kit is essential for early detection of the virus. Samples such as bursa tissue, cloacal swabs, or blood are collected from chickens at regular intervals (e.g., weekly for chicks within the first few weeks after hatching and monthly for older chickens). For example, in a large - scale broiler chicken farm, samples are collected from different age - groups of chickens. If IBDV is detected in a group of young chicks, immediate isolation of the infected birds can be carried out. Enhanced biosecurity measures are then implemented, including strict disinfection of the poultry houses, improved ventilation, and restricted movement of personnel and equipment to prevent further spread within the farm.

2. Disease Diagnosis in Poultry：When chickens show symptoms such as depression, diarrhea, or abnormal growth, the IBDV nucleic acid detection kit serves as a crucial diagnostic tool. It allows for a quick and accurate determination of whether IBDV is the causative agent. In a layer chicken farm where some young chickens are experiencing these symptoms, using this kit to test the samples can quickly confirm the presence or absence of IBDV. This timely diagnosis is essential for implementing appropriate treatment and control measures. Although there is no specific antiviral treatment for IBDV, supportive care like electrolyte supplementation can be provided to the sick birds, and steps can be taken to prevent the spread of the virus to the remaining healthy flock.

3. Vaccine Efficacy Monitoring：In poultry farms that have implemented IBDV vaccination programs, the detection kit plays a vital 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 IBDV or show a high viral load, it may indicate vaccine failure or exposure to a variant strain of the virus. This information can guide farmers to adjust their vaccination strategies, such as choosing a different vaccine strain or adjusting the vaccination schedule.

4. Quarantine and Import/Export Control：In international trade of poultry and poultry products, the IBDV nucleic acid detection kit is an important part of quarantine procedures. All incoming and outgoing poultry, hatching eggs, and processed poultry products are screened to prevent the international spread of IBDV. 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 IBDV infections.
