In our murine pneumococcal meningitis model, however, WBB6F1-KitW/Wv developed disease comparable to their WT littermates WBB6F1-Kit+/+: The clinical scores, body temperatures, and the meningitis-associated losses in body weight did not differ significantly between both mouse strains (Figures 4A–C). Here, KIT is linked to pneumococcal meningitis.
