Facing a constant battle against Porcine Reproductive and Respiratory Syndrome (PRRS) in swine herds? The challenge of monitoring vaccination success and differentiating between vaccinated and truly infected animals has always been a hurdle. But what if there was a way to gain a clearer picture? Let’s dive into how the new virotype PRRSV EU Vax RT-PCR Kit from INDICAL BIOSCIENCE is changing the game.
This innovative kit marks a significant advancement, being the first of its kind to detect and differentiate all major live-attenuated PRRSV-1 vaccines in a single run. This breakthrough offers crucial advantages for veterinarians, diagnostic laboratories, and swine producers, providing timely, actionable data to improve herd health management.
Why is monitoring vaccination status so important? PRRSV is a major economic burden in pig production, causing reproductive losses in sows and respiratory issues in young pigs. With PRRSV-1 prevalent across Europe, vaccination programs are a standard practice. However, determining if vaccination is truly effective is critical.
When PRRSV RNA is detected, veterinarians need to know if the animals are shedding the wild-type virus, indicating infection, or if it’s just the vaccine strain. Without this distinction, it’s impossible to accurately assess herd status or quickly respond to potential risks.
So, what makes the virotype PRRSV EU Vax RT-PCR Kit stand out? Traditional methods like sequencing can be expensive, time-consuming, and may lack sensitivity, especially with low viral loads. This kit provides a practical, rapid alternative.
Here are the key features that set it apart:
- Comprehensive Vaccine Coverage: Designed to simultaneously detect and differentiate all major live-attenuated PRRSV-1 (EU) vaccines currently used in Europe, a market first.
- Rapid Results: Get results in just 67 minutes* from the RT-PCR run.
- High Sensitivity: Detect down to 5 copies per sample, offering high confidence even with low viral loads.
- Built-in Process Control: Includes an exogenous internal control to monitor amplification in each run.
- Flexible Sample Types: Validated for serum, plasma, saliva, tissue, and processing fluids, making it versatile for veterinary diagnostic labs.
*Runtime may vary depending on PCR cycler and settings used.
How does this benefit herd health management? This assay offers several tangible benefits for herd health and diagnostic operations:
- Efficient DIVA Capability: When used with the virotype PRRSV 2.0 RT-PCR Kit (detects both PRRSV-1 and PRRSV-2 genotypes), it supports DIVA (Differentiating Infected from Vaccinated Animals) strategies, differentiating between vaccine strains and wild-type virus.
- Faster Decision-Making: With a runtime of just over an hour and high sensitivity, diagnostic labs can deliver quicker results, enabling producers to respond faster to potential herd infections, vaccination failures, or management gaps.
- Cost-Effective Workflow: Reduces the need for sequencing, which can be costly and unreliable for low-viral-load samples, allowing labs to allocate resources more efficiently. Differentiation in a single run saves both time and materials.
- Strengthened Confidence in Vaccination Programs: Provides objective data to both producers and veterinarians, supporting confident decisions on adjusting vaccination schedules, implementing biosecurity measures, or pursuing further diagnostics.
- Supports Traceability and Biosecurity: Supports traceability, auditing, and risk management in the pork value chain in increasingly stringent regulatory and market environments.
In conclusion: For the swine industry, where PRRS remains a persistent and costly threat, diagnostic innovation is essential. The virotype PRRSV EU Vax RT-PCR Kit offers a new level of precision, allowing laboratories and producers to more confidently monitor vaccine performance, distinguish between vaccine and infection, and make timely decisions that protect herd health and productivity.
By integrating rapid, high-sensitivity differentiation of PRRSV-1 (EU) vaccine strains into routine workflows, the kit supports improved surveillance, better vaccination strategies, and, ultimately, stronger herd resilience.
