Animal reservoir mystery solved
A new assay that uses mitochondrial DNA that mutates faster than nuclear DNA has allowed scientists at Washington University in St. Louis to identify one of the major animal reservoirs for the ehlichioses, STARI and other tick-borne diseases in the southeastern United States. The animal turned out to be the eastern gray squirrel.
Emerging tick-borne diseases: a domestic ecological mystery
A new test allows scientists to discover whether ticks are carrying disease-causing bacteria and which animals provided their last blood meal. Results suggest three emerging diseases in the St. Louis area are carried by lone star ticks feeding on record-high populations of white-tailed deer.
