Oxygen uptake in green iguana (Iguana iguana) injected with bacteria

Abstract

1. 1.|Green iguanas (I. iguana) were maintained at a constant body temperature of 35.5[deg]C and injected with either saline or a dose of bacteria which had been previously shown to induce a fever by 3 h post-injection.2. 2.|There were no significant differences in the oxygen uptake between the lizards injected with saline and bacteria.3. 3.|We conclude that green iguanas do not increase their internal heat production as an effector response to the raised thermoregulatory "set-point" that occurs during fever.
