                    Snippet: Virus isolation and titration was performed only from the nasal swabs collected from the seeder pigs prior to commingling, and from tissues at necropsy on MDCK cell monolayers [37] . Supernatants showing cytopathic effect (CPE) were titrated using ten-fold serial dilution and expressed as a log 10 TCID 50 /mL calculated by the Spearman-Kärber method [39] ......
