In all the samples, TTSuV1 DNA was detected by real time PCR as previously described (Brassard et al., 2010; Segales et al., 2009). TaqMan PCR assays were performed in25 mL reaction mixture comprising 2.5 mL extracted DNA and 22.5 mL master mix, which was made with the BrilliantI QPCR Core Reagent Kit (Stratagene) and contained 5.0 mmol/L MgCl2, 300 nmol/L QCOM forward primer,150 nmol/L QCOM reverse primer, and 300 nmol/L TaqManprobe. PCR amplification was performed with a Stratagene Mx 3005p system (Brassard et al., 2010). Student’s t test was used to compare viral loads.
