When compared to naive mice, numbers of B220+ B lymphocytes were significantly higher in CCUG 30485 strain infected mice, both at days six and 16 p.i. (p<0.0001 and p<0.05, respectively; Fig 3C), and 16 days following C1 strain infection (p<0.0005; Fig 3C). The gene discussed is PTPRC; the disease is infection.
