Table 1. GFP-myosin Vb tail expression inhibits RSV replication and redirects budding to the basolateral cell surface.

	Total virus yield, log10 pfu/ml*			% Apical RSV‡
Route of infection	+ Dox.	– Dox.	Fold reduction†	+ Dox.	– Dox.
Apical	4.2	1.6	398	97	24
Basolateral	5.2	4.7	3	>99	10

^*Total virus yield was calculated by separately determining the titer of virus released into the apical or basolateral supernatants (pfu/ml), adding those values, and converting the total to a log₁₀ pfu/ml value

^†Fold reduction was calculated by dividing the virus titer (pfu/ml) in the presence of doxycycline (Dox.) by that in the absence of doxycycline

^‡Percentage of apical RSV was calculated by dividing the titer of virus recovered from the apical supernatant (pfu/ml) by the combined apical and basolateral supernatant titers (pfu/ml) and multiplying the quotient by 100
