^aNeuronal cultures infected with 10⁶ PFU of either CS5 or gH⁻TK⁻IE110LacZ per well. 

^bCMV IE1 reporter promoter driving lacZ expression in CS5-infected wells. 

^cOne well per data point was fixed and dually immunostained for β-gal and β-tub, and the number of neurons (β-tub⁺) was counted. 

^dPercentage of neurons showing β-gal expression. 

^eIE110 reporter promoter driving lacZ expression in gH⁻TK⁻IE110LacZ-infected wells. 

^fND, not determined.
