At 3 day post-infection, higher mRNA levels of C-C motif chemokine ligand 2 (CCL2), C-C motif chemokine ligand 3 (CCL3) and C-X-C motif chemokine ligand 10 (CXCL10) were found in the liver of mice infected with the WT strain as compared to mice infected with the ΔspvB strain (Figure 4e–g). The gene discussed is CXCL10; the disease is infection.
