Effects of a chromated-copper-arsenate wood preservative on the bacterial degradation of pentachlorophenol.

abstract：:Lyme disease is a tick-borne disease that is emerging in Canada. The disease is caused by spirochetes of the Lyme borreliosis group, which is expanding as new species are discovered. In Canada, Lyme disease risk has so far been assessed primarily by detection of Borrelia burgdorferi sensu stricto. Of Ixodes scapularis...
