TABLE 1.

Replication of a minor-group and a major-group virus in two cell lines^a

Virus	Titer at indicated h p.i. in:
	HeLa cells				HEp-2 cells
	0	24	48	72	0	24	48	72
HRV2	2.7 × 104	1.6 × 107	5.7 × 105	8.5 × 103	2.3 × 104	2.8 × 107	8.5 × 105	4.6 × 104
HRV89	2.0 × 104	2.9 × 106	3.1 × 105	2.5 × 104	5.6 × 103	8.5 × 104	4.1 × 105	1.2 × 106

^aCells were challenged with HRVs at a MOI of 1, and the viral titer was determined after the times specified. Underlined values indicate that the cells had lysed.
