In the Leaf River Herd, preliminary results suggest a prevalence of B. tarandi in 89% of animals targeted (n=9) due to their poor general condition when compared to a prevalence of 28% in samples randomly collected (n=53) and those obtained from hunters for the years 2007-2008.

In the George River Herd, preliminary results (n= 57) suggest a prevalence of B. tarandi of 15.8% in randomly collected caribou and those obtained from hunters for the years 2007-2008.

In the Bluenose West Herd, preliminary results suggest a prevalence of B. tarandi of 59 % (n=17) in randomly collected caribou and those obtained from hunters for the years 2007-2008.

In the Bathurst Herd, preliminary results suggest a prevalence of B. tarandi of 40 % (n=89) in randomly collected caribou and those obtained from hunters for the years 2007-2008.

In the Southampton Herd, preliminary results suggest a prevalence of B. tarandi of 12 % (n=17) in randomly collected caribou and those obtained from hunters for the years 2007-2008.

B. tarandi was not detected in the 46 examined samples taken from the Akia-Maniitsoq herd in Greenland.

Results also suggest that factors influencing prevalence might be the season, the gender, the age and the geographical location. These preliminary results will be evaluated in the comprehensive epidemiologic analysis
