FIG 5.

Antiviral activity against 2 sH1N1 strains, Siriraj-03/2006 (oseltamivir sensitive) and SirirajICRC_SEA-3479/2008 (oseltamivir resistant), using the (A) hemagglutination inhibition (HI) assay and (B) neutralization curves as determined by neutralization (NT) assay. HI titers were derived from 6 BAL fluid samples and are shown as the geometric mean with 95% CI. The neutralization curves were derived from one BAL fluid sample that shows high HI activity. The experiment was run in duplicate, and results are shown as the arithmetic mean ± SEM. Both the HI and NT assays were run in duplicate.
