Experimental design and transmission events per experiment and density treatment for SNV transmission experiments in deermice in outdoor enclosures near Butte, Montana, 2007–2008^†.

Exp = experiment; High = high density treatment; low = low-density treatment. †Each enclosure had one donor mouse. aSee Figure 1. bAdjusted; number of susceptible mice used to calculate transmission incidence. cExcludes 1 mouse never recaptured after initial release into the enclosure. dExcludes 3 mice never recaptured after initial release, 2 susceptible mice from low-density enclosure in which the infection status of donor was unclear, and 1 mouse which we cannot rule out as being exposed prior to release in the enclosures. eIncludes 3 substitute susceptible mice that were released into the enclosures to replace dead mice and 1 escapee to keep population densities constant. fExcludes 3 mice never recaptured after initial release into the enclosure.
