Bovine Infectious Rhinotracheitis Virus (IBRV) Nucleic Acid Test Kit (Lyophilized)

Symptoms

• Respiratory Form: Infected cattle often exhibit fever, with temperatures reaching 39.5 - 42°C (103.1 - 107.6°F). There is nasal discharge, which may start as clear and later become mucopurulent. Coughing, sneezing, and labored breathing are common. In severe cases, cattle may experience difficulty breathing, with open - mouth panting and increased respiratory rate.

• Genital Form: In bulls, there may be inflammation of the prepuce and penis, with the appearance of vesicles and ulcers. In cows, vulvovaginitis can occur, accompanied by a mucopurulent vaginal discharge. There may also be a decrease in fertility, with an increased incidence of abortions, especially in the second trimester of pregnancy.

• Ocular Form: Conjunctivitis is a typical symptom, with redness, swelling, and discharge from the eyes. In some cases, corneal opacity may develop, which can affect the animal's vision.

• Meningoencephalitic Form: This form is less common but more severe. Affected calves may show neurological symptoms such as depression, incoordination, muscle tremors, and even convulsions.

Clinical Applications

• Early Diagnosis: The IBRV nucleic acid detection reagent allows for the rapid and accurate detection of the virus in the early stages of infection. For example, when cattle show initial symptoms such as fever and nasal discharge, veterinarians can use this reagent to quickly confirm whether IBRV is the cause, enabling timely treatment and isolation of infected animals to prevent the spread of the disease.

• Herd Screening: Regular screening of cattle herds using this reagent is essential for monitoring the health status of the herd. It can detect subclinical infections, helping to identify and manage carrier animals. This is particularly important in large - scale dairy and beef cattle operations to maintain the overall health and productivity of the herd.

• Quarantine and Import - Export Control: Before introducing new cattle into a herd or for international trade, IBRV nucleic acid testing is often required. This helps prevent the introduction of the virus into disease - free areas and ensures the compliance of exported cattle with international health standards.

• Vaccine Efficacy Evaluation: After vaccination, the reagent can be used to assess the effectiveness of the vaccine by detecting the presence of the virus in vaccinated animals. If a significant number of vaccinated cattle still test positive for IBRV, it may indicate that the vaccine is not providing adequate protection, and adjustments to the vaccination strategy may be needed.
