Summary of SARS-CoV Pulmonary Viral Load in Common Marmoset by Quantitative PCR (Experiment 2)

Experiment day	PCR-positive lung samples (%)*	Average concentration^† (log₁₀ copies/g tissue)	Peak concentration (log₁₀ copies/g tissue)
Day 4	12 of 15 (80%)	5.0	7.9
Day 7	8 of 15 (53%)	4.3	5.6
Total	20 of 29 (69%)	4.7	7.9

Combined results from routine processing and direct tissue RNA extractions.

^†

This calculation includes maximum possible negative (threshold) values for samples that were negative by PCR.
