Immunosuppression following stress has been implicated as a contributing factor in infectious diseases of koalas and it has been suggested that faecal cortisol measurement may be a suitable non-invasive methodology for quantifying stress. This study used an adrenocorticotropic stimulation test to induce secretion of cortisol. Measurement in serum samples showed an elevation of serum cortisol for at least 4 h post injection, but there was no corresponding peak in corticosterone or cortisol concentrations in extracts from the faeces. There was a sudden rise in cortisol levels that was probably related to contamination with urine. The authors conclude that rigorous validation is needed for each species when attempting to use faecal cortisol as an index of stress.
