Fig. 1From: Borrelia burgdorferi induces a type I interferon response during early stages of disseminated infection in miceArthritis development in infected mice. Groups of 15 C3H/HeJ mice were inoculated intradermally by needle with 1×104 spirochetes of B. burgdorferi strains B515 or B331, or with medium (control). Tibiotarsal joints were measured on days 0, 7, 14, 21, and 28 post-infection. Measurements are shown as the mean value of each experimental group, with bars indicating the standard deviation. ****, P < 0.0001 relative to the control and B331-infected groupsBack to article page
