Spleens collected from C57BL/6 mice infected with this strain showed fewer cytokines/chemokines expressed early and showed a sustained increased expression of IL-6, IP10, and MIG with an early (2 days post-infection) transient increase of IFN-γ (Fig 9B) When cytokines/chemokines expressed in lungs of C57BL/6 mice exposed to HBPUB10134a were examined (Fig 10B), there was clearly an earlier and more intense immune response than in lungs of BALB/c mice exposed to HBPUB10134a (Fig 10A). Here, CXCL10 is linked to infection.
