Dynamic Distribution of Muscovy duck reovirus in the Challenged Ducks Detected by RT-PCR

Dynamic distribution of muscovy duck reovirus in the challenged ducks was detected by RT-PCR.When one-day-old muscovy ducks were challenged with muscovy ducks reovirus MW9710 strain,viral RNA could be detected in the liver and spleen in three days,but not done in 32 days.The detection rate was the highest in 7 to 14 days.in six kinds of tissues,The viral RNA could be detected,the highest detection rate was liver(68.9%),and spleen(62.2%)heart(48.9%)kidney(46.7%),pancreas(35.6%) in order,but that of anus was lowest(17.8%).The results displayed dynamic distribution of muscovy duck reovirus.
