Table 2. Detailed results of microneutralisation assays against TOSV and PUNV.

		Punique virus					Total

Bold values corresponded to sera reflecting infection by PUNV, stared values to sera demonstrating infection by TOSV and underlined values to sera for which cross-neutralisation precluded definitive conclusion.
