Primary mammary tumor burden in mock and HV-68 infected mice. At death or at day 44 following tumor cell transplantation, groups of mice (N = 10) were euthanized and primary mammary tumor tissue excised and weighed. Panel A shows mean tumor weights (± standard deviations). Panel B shows the ratio of average body weight to average tumor weight (± standard deviations) as a measure of tumor burden.
