Tuberculosis strain spread by the fur trade reveals stealthy approach of epidemics
Date:4/11/2011

rived strains made scant inroads into the native population. That lack of transmission was likely due to a lack of social interaction between the settlers and the natives, and preserved the dominance of the French Canadian strain.

Pepperell and Feldman said it is too early to tell how applicable the results of their study will be in other settings, as not enough is known about the factors affecting tuberculosis migration in general.

"This approach of looking at the genetics in concert with epidemiology is fairly new in the world of bacterial research," Pepperell said. "I would say in terms of the overall research on TB, it is a little bit like the organism itself.

"TB research has had a very long latent period, and now we are kind of getting into an expansion phase, which is a really good thing."
