Plasma cytokine concentrations following intravenous inoculation with CVB3.

<p>Concentrations of single cytokines IFN-g (panel A), TNF-a (Panel B), and IL-6 (panel C) are demonstrated. Mean cytokine concentrations for the two animals receiving high dose (10⁷ pfu) CVB-H3 by i.v. (▪) or the single animal infected by enteral infection (<b>○</b>) are shown. Mean cytokine concentration +/− SEM for animals receiving low dose (10⁶ pfu) CVB-H3 (▴) or CVB-MCH (Δ) by i.v. are shown
