Project 4. Genetic analyses of host connectivity and cross-species transmission
• Hyp. 4.1. Host species will be a better predictor of Brucella abortus genetic similarity than geographic
location reflecting a limited amount of cross-species transmission.
• Hyp. 4.2. Few seropositive elk from unfed populations will be immigrants from the supplemental
feedgrounds reflecting high levels of on-site transmission.
Project 4. Genetic estimates of transmission & origins of infected elk
Estimating the relationships between
host density, transmission, and
prevalence implicitly assumes that the
disease dynamics are driven by
local/internal processes rather than
immigration from other populations or
spill-over from other hosts. We will
use genetic analyses of B. abortus
isolates and elk to assess the amount
of elk movement among populations
and B. abortus transmission among
species and populations.
