Serum insulin levels in infected and control mice. A: Insulin levels in infected and control mice during the course of infection. B: Insulin levels after injection of beta-adrenergic agonist (Ar). Note the reduced insulin response after stimulation of the adipocyte β-adrenergic receptor in infected mice. C: Insulin levels after injection of L-arginine (LR). Note the reduced insulin response after LR stimulation in infected mice. In all experiments: n = 4; P < 0.05. All determinations were made on mice that were fasted for at least 7 hours.
