Hematopoietic consequences of SFFV-cEPOR viruses in infected mice. (A) Hematocrits of mice infected with SFFV-cEPOR (•, left) or SFFV-cEPORYF (▴, right) measured serially following inoculation. Each symbol represents a value from an individual animal, and the dashed line indicates the normal hematocrit of an adult mouse. (B) Spleen weights of mice infected with SFFV-cEPOR or SFFV-cEPORYF determined after euthanizing the mice at the end of the experiment. Each symbol represents a value from an individual animal, and the dashed line indicates the normal spleen weight of an adult mouse.
