Awanui Veterinary is pleased to launch Fast Worm ID – Gastrointestinal Nematode (GIN) PCR. We developed this new diagnostic test in partnership with, and with funding from, Beef + Lamb New Zealand. It provides veterinarians with earlier species-level insight into parasite infections in sheep and cattle.
How does GIN PCR work?
This DNA-based test identifies gastrointestinal nematode species directly from faecal samples, with results available in approximately three working days. Traditional larval culture is limited by turn-around time and practical constraints, particularly in time-sensitive or low egg count situations. By detecting parasite DNA directly, GIN PCR enables earlier identification of the species contributing to infection.
Gastrointestinal nematodes continue to present a significant clinical and production challenge. Species such as Haemonchus contortus in sheep and Ostertagia ostertagi in cattle can contribute to production loss and clinical disease prior to increases in faecal egg counts. Earlier species identification supports more informed and proactive parasite management decisions.
Igor Obradovic, Head of Business Development at Awanui Veterinary, says the test addresses a key gap in current diagnostic approaches. “GIN PCR provides veterinarians with earlier species-level insight, particularly in situations where timing or practical limitations reduce the usefulness of larval culture. It supports more timely and informed treatment decisions.”
How do I use GIN PCR?
GIN PCR is a semi-quantitative assay, reporting relative parasite burden rather than eggs per gram. Interpret results alongside faecal egg counts and clinical findings to provide a comprehensive assessment of parasite burden and significance. The test does not yet provide a fully quantitative result and is not currently suitable for faecal egg count reduction testing (FECRT).
We developed and validated under New Zealand conditions and it integrates into existing diagnostic workflows using standard faecal samples. Its ability to detect low levels of parasite DNA makes it particularly useful in cattle, and in early or low egg count scenarios.
GIN PCR complements existing diagnostic methods. It provides a practical option for rapid species identification when timing and specificity are important.
Species insight. Faster decisions.
This new tool is now available through Awanui Veterinary laboratories nationwide.
