TABLE 3.

SIV RNA expression in the LNs of i.v. infected macaques at 14 days p.i.

Animal	Inoculum (TCID₅₀, i.v.)^a	No. of RNA-positive cells per^b:
Animal	Inoculum (TCID₅₀, i.v.)^a	Section	mm²
AT 88	1 × 10², wt	348.5	52
AR 80	1 × 10², wt	234.5	16.1
AT 62	2.35 × 10⁴, delta	17.25	3.15
AT 84	2.35 × 10⁴, delta	8.2	0.4
AR 83	2.35 × 10⁴, delta	15	0.72
AR 85	2.35 × 10⁴, delta	132	6.5

wt, wild-type virus; delta, delta nef virus.

Average numbers of RNA-positive cells (by ISH) at day 14. LNs were biopsied at days 2, 5, 7, and 14. However, negligible numbers of SIV-positive cells were detected before day 14 (ranging from 0.08 to 2.25 SIV-positive cells per mm² or 0.5 to 38 SIV-positive cells per section at day 7).
