Of note, infection of neonatal mice with RRV significantly inhibited the recovery of colons with adequate DNA reads, with colonization documented in ≤ 20% of RRV-infected mice at day 3 (RR = 0.24, or 4.1 times less colonization in RRV infection; P < 0.001) and day 10 (RR = 0.77, 1.3 times less colonization in RRV infection; P < 0.01) when compared to control in WT and Cxcr2-/- mice (Table 1). The gene discussed is CXCR2; the disease is infection.
