Cytochalasin D does not reduce virus yields

Cell type	Virus yield, pfu × 10−5/ml
	9 h.p.i.		24 h.p.i.
	−CytoD	+CytoD	−CytoD	+CytoD
MDCK	68	87	110	96
MDBK	7.1	7.8	15	21

Vero C1008	0.7	2.1	1.4	4.5
BHK-21	4.8	3.2	13	17

Infection was carried out either in the absence of cytochalasin D or in the presence of cytochalasin D at 10 μg/ml. pfu, Plaque-forming units.
