Abstract : The objective of this study was to investigate methods of decontaminating early goat embryos that had been infected in vitro with bluetongue virus (BTV). Embryos were isolated from in vivo-fertilized BTV-free goats. Zona pellucida (ZP)-intact 8 to 16 cell embryos were cocultured for 36 h in an insert over a Vero cell monolayer infected with BTV serotype 8. The embryos were then treated with one of five different washing procedures. The treatment standard (TS) comprised phosphate-buffered saline (PBS) + 0.4% BSA (five times over for 10 s), Hank's +0.25% trypsin (twice for 45 s), and then PBS + 0.4% BSA again (five times for 10 s). The four other washing procedures all included the same first and last washing steps with PBS but without BSA (five times for 10 s) and with PBS + 0.4% BSA (five times for 10 s), respectively. The intermediate step varied for each washing procedure. Treatment 1 (T1): 0.25% trypsin (twice for 45 s). Treatment 2 (T2): 0.25% trypsin (twice for 60 s). Treatment 3 (T3): 0.5% trypsin (twice for 45 s). Treatment 4 (T4): 1% hyaluronidase (once for 5 min). After washing, the embryos were transferred and cocultured with BTV indicator Vero cell monolayers for 6 h, to detect any cytopathic effects (CPE). The effectiveness of the different washing techniques in removing the virus was evaluated by RT-qPCR analysis. The TS, T1, T3, and T4 trypsin or hyaluronidase treatments did not eliminate BTV; Treatment 2 eliminated the virus from in vitro infected goat embryos.
