5 minute test replaces McMaster and other slide technologies
Haemonchus Contortus, “Barber’s Pole”, is a gastrointestinal parasite infecting small ruminants and camelids worldwide. Heavy infestation can lead to anemia, decreased production, quality of wool, edema, and mortality. Current methods of identification involve a lengthy process of larval cultivation taking up to 3 days to 2 weeks for results. Delayed results and treatment can greatly influence mortality rate. Parasight has developed a validated assay with results achieved in less than 20 minutes. Results are given in EPG for quantity of strongyle type ova; the Barber’s Pole assay results yield a percentage of Haemonchus Contortus, if positive.
The most commonly used method for detecting Haemonchus infection is coproculture, where the sample is incubated for 10 or more days to hatch the eggs and release larvae. The need for a highly trained analyst has meant that this test can only be performed at diagnostic labs with appropriately trained personnel.
Scientists at Parasight System have adapted the system’s fluorescence imaging technology to specifically detect and count Haemonchus eggs in sheep feces by using a special fluorescent dye that only stains this species of hookworm. As a result, the percentage of Haemonchus eggs in a sample can now be determined on-site in twenty minutes by operators with no technical experience whatsoever.
This research has been peer-reviewed and will soon be published in the International Journal for Parasitology, the leading research journal in this field.
