In this study we have monitored the stress of Iberian ibex at individual level within the course of an experimental
infection with Sarcoptes scabiei mites. For this purpose we have measured faecal 11-ketoetiocholanolone (11-k)
using high-performance liquid chromatography coupled with tandem mass spectrometry (HPLC-MS/MS). We
used linear mixed models to explore the effects of host sex and age, clinic (mange status) and time (number of
days post-infection) on the concentration of faecal 11-k. The most parsimonious model included clinic, time and
host age, which explained 76.6% of the variance of the response variable. Moreover, the concentration of faecal
11-k varied greatly between individuals. Our results evidence the stressor nature of the disease and highlight the
negative effects on hosts due to cortisol release and activity.
