Chicken Infectious Bronchitis Virus (AIBV) Nucleic Acid Test Kit (Lyophilized)

Avian Infectious Bronchitis Virus (AIBV), a member of the Coronaviridae family, is a highly contagious virus that significantly impacts the poultry industry. It primarily targets the respiratory, urogenital, and gastrointestinal tracts of chickens. AIBV infections can cause a wide range of symptoms. In the respiratory system, it leads to tracheal rales, coughing, sneezing, and nasal discharge. In the urogenital system, it can result in decreased egg production, poor egg quality, and nephritis in laying hens. In young chicks, it may cause stunted growth and high mortality rates. These symptoms, combined, lead to substantial economic losses due to reduced productivity, increased mortality, and costs associated with disease control.

Clinical Applications

1. Poultry Farm Surveillance：In commercial poultry farms, regular screening using the AIBV nucleic acid detection reagent is essential for early detection of the virus. By collecting samples such as tracheal swabs, cloacal swabs, or tissue samples from chickens at regular intervals (e.g., every 2 - 3 weeks), farmers and veterinarians can identify the presence of AIBV in a timely manner. For example, in a large - scale broiler chicken farm, samples are collected from different age - groups of chickens. If AIBV is detected in a group of young chicks, 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 such as respiratory distress, abnormal egg production, or stunted growth, the AIBV nucleic acid detection reagent serves as a vital diagnostic tool. It allows for a quick and accurate determination of whether AIBV is the causative agent. In a layer chicken farm where hens are experiencing a decline in egg - laying performance and some show signs of respiratory illness, using this reagent to test the samples can quickly confirm the presence or absence of AIBV. This timely diagnosis is essential for implementing appropriate treatment and control measures. Although there is no specific antiviral treatment for AIBV, supportive care can be provided to the sick birds, and measures 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 AIBV 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 AIBV or show a high viral load, it may indicate vaccine failure or exposure to a heterologous 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 AIBV 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 AIBV. 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 AIBV infections.
