Bovine Parainfluenza Virus Type 3 (BPIV-3) Nucleic Acid Test Kit (Lyophilized)

Symptoms

• Respiratory Distress: Infected cattle typically display symptoms such as coughing, which can be persistent and dry initially, and may later become productive with the presence of mucus. There is often an increased respiratory rate, and the animals may exhibit labored breathing, especially during exertion or when lying down.

• Nasal Discharge: A clear to mucopurulent nasal discharge is common. In the early stages, the discharge is usually clear, but as the infection progresses, it may turn yellowish - green and become thicker.

• Fever: Affected cattle usually develop a fever, with body temperatures ranging from 39.5°C to 41°C (103.1°F to 105.8°F). The fever may last for several days and is often accompanied by general malaise.

• Ocular Symptoms: Some infected cattle may show conjunctivitis, characterized by redness, swelling, and a watery discharge from the eyes.

Clinical Applications

• Rapid Diagnosis in Outbreaks: During respiratory disease outbreaks in cattle herds, the BPIV - 3 nucleic acid detection reagent is crucial for quickly identifying the virus as the causative agent. For example, when multiple cattle in a herd simultaneously show symptoms of cough, fever, and nasal discharge, this reagent can help veterinarians rapidly diagnose whether BPIV - 3 is involved, enabling prompt implementation of appropriate control measures.

• Differential Diagnosis: It aids in differentiating BPIV - 3 from other similar - acting bovine respiratory pathogens such as BRSV, IBRV, and BVDV. Since the symptoms of these diseases can be similar, accurate diagnosis is essential for targeted treatment. For instance, if a calf presents with respiratory symptoms, testing for BPIV - 3 can help rule out other viruses and guide specific treatment strategies.

• Herd Health Monitoring: Regular screening of cattle herds using this reagent is an important part of herd health management. It can detect subclinical infections, allowing for the identification and management of carrier animals. This is particularly important in intensive cattle - raising operations to maintain the overall health and productivity of the herd.

• Vaccine Efficacy Assessment: After vaccination against BPIV - 3, the reagent can be used to evaluate the effectiveness of the vaccine. By detecting the presence of the virus in vaccinated animals, veterinarians can determine if the vaccine is providing adequate protection. If a significant number of vaccinated cattle still test positive for BPIV - 3, it may indicate the need to adjust the vaccination protocol.
