Viral load in mice. (a–d) Viral load of lung, brain, blood, and feces samples. Data are expressed as the means ± SEMs, , , . The viral RNA in homogenized samples was extracted, and the amount of the M gene was measured by RT-qPCR with absolute quantification. The viral load was calculated by referring to the standard curve and expressed as log10 copies/g.
