Quick Takeaways:
- Pictor highlighted an independent peer-reviewed study from researchers at Texas A&M University showing that its PictVet assay detected anti-Mycoplasma bovis IgG antibodies in bovine nasopharyngeal swabs with 97.6% accuracy, 100% sensitivity, and 95.2% specificity, using a multiplex antigen panel.
- The study evaluated archived swab samples from 100 feedlot steers and demonstrated that the assay can monitor immune responses through a non-invasive sampling method, offering an alternative to blood-based testing for bovine respiratory disease (BRD) surveillance.
- Published in the journal Frontiers in Veterinary Science, the research also showed strong inter-operator reproducibility and reliable detection at low sample dilutions, adding to the growing body of evidence supporting Pictor’s targeted proteomic platform for livestock health monitoring.
Why It Matters?
The Texas A&M study positions Pictor’s PictVet assay as a highly accurate, non‑invasive tool for monitoring Mycoplasma bovis–associated immune responses in beef cattle, supporting broader use of targeted proteomics in herd health surveillance.
The multiplex IgG assay on nasopharyngeal swabs achieved about 97.6% accuracy, 100% sensitivity, and 95.2% specificity, with excellent inter‑operator reproducibility and robust detection even at low dilutions, showing it can reliably track BRD-related antibody responses from swab samples rather than blood.
