Case Study Detail: PBFD Outbreak Management
Background: A large psittacine breeding facility experienced suspected PBFD (Beak and Feather Disease Virus) outbreak. SENO conducted comprehensive qPCR testing on 120 birds across 15 species.
| Parameter | Detail |
|---|
| Samples tested | 120 oral swabs |
| Testing method | BFDV qPCR (TaqMan probe) |
| Positivity rate | 22.5% (27/120) |
| Viral load range | 10² – 10⁶ copies/µL |
| Species affected | Cockatoos (highest), African Greys (moderate), Macaws (lowest) |
| Outbreak outcome | Quarantine protocols implemented; 90% of negative birds remained negative at 6-month follow-up |
Case Study Detail: Breeding Pair Optimization
Background: A commercial parrot breeder with 50+ breeding pairs sought to optimize pair formation by confirming sex and disease status before introducing new birds.
| Metric | Before SENO Testing | After SENO Testing | Improvement |
|---|
| Incorrect pairings | ~15% | < 1% | 14× reduction |
| Failed breeding attempts | ~25% | ~10% | 2.5× reduction |
| Disease transmission between cages | 3-5 cases/year | < 1 case/year | 4× reduction |
| Annual hatch rate | ~60% | ~80% | 33% increase |
| Revenue (3-year projection) | Baseline | ~40% increase | Significant |
Case Study Detail: DNA Fingerprinting Theft Recovery
Background: 15 high-value racing pigeons were stolen from a prominent breeder in Europe. Police recovered 12 birds from a suspect, but visual identification was inconclusive. SENO performed DNA fingerprinting on all recovered birds and reference samples from the owner.
| Evidence Item | Result |
|---|
| DNA fingerprint panel | 15-plex STR markers |
| Match probability | < 10⁻¹⁰ (effectively unique) |
| Number of matches confirmed | 11 of 12 recovered birds positively identified |
| Legal outcome | Successful prosecution, birds returned to owner |
| Client recovery value | €75,000+ (insurance valuation) |
