FIG 2.

Immunogen-specific IgM, IgG, and IgA were detected in sera recovered from chinchillas after TCI. Blood was collected 9 days after receipt of the second of two immunizing doses delivered a week apart and prior to NTHI challenge. Serum was assessed for relative quantity of immunogen-specific IgM, IgG, and IgA by ELISA. There was no statistically significant difference in the total quantities of antibody induced by TCI via band-aid among the cohorts. The geometric mean ± SD for each antibody isotype is shown.
