Dispersal of Mycobacterium tuberculosis via the Canadian fur trade.
Patterns of gene flow can have marked effects on the evolution of populations. To better understand the migration dynamics of Mycobacterium tuberculosis, we studied genetic data from European M. tuberculosis lineages currently circulating in Aboriginal and French Canadian communities. A single M. tuberculosis lineage, characterized by the DS6(Quebec) genomic deletion, is at highest frequency am...
متن کاملLoss of genetic diversity in sea otters (Enhydra lutris) associated with the fur trade of the 18th and 19th centuries.
Sea otter (Enhydra lutris) populations experienced widespread reduction and extirpation due to the fur trade of the 18th and 19th centuries. We examined genetic variation within four microsatellite markers and the mitochondrial DNA (mtDNA) d-loop in one prefur trade population and compared it to five modern populations to determine potential losses in genetic variation. While mtDNA sequence var...
متن کاملThe oldest known fur seal.
The poorly known fossil record of fur seals and sea lions (Otariidae) does not reflect their current diversity and widespread abundance. This limited fossil record contrasts with the more complete fossil records of other pinnipeds such as walruses (Odobenidae). The oldest known otariids appear 5-6 Ma after the earliest odobenids, and the remarkably derived craniodental morphology of otariids of...
متن کاملThe Fur Transcription Regulator and Fur-Regulated Genes in Clostridium botulinum A ATCC 3502
Clostridium botulinum is a spore-forming bacterium that can produce a very powerful neurotoxin that causes botulism. In this study, we have investigated the Fur transcription regulators in Clostridium botulinum and Fur-regulated genes in Clostridium botulinum A ATCC 3502. We found that gene loss may be the main cause leading to the different numbers of Fur transcription regulators in different ...
