Background:
It would be clinically advantageous to develop a method of body temperature evaluation in cynomolgus macaques (Macaca fascicularis) that did not require sedation, restraint, surgical manipulation, or expensive equipment.
Methods:
Body temperatures of 51 cynomolgus macaques were taken with rectal thermometry and non-contact infrared thermometry (NIFT) on the shoulder, face, abdomen, and axillary region.
Results And Conclusions:
Body temperature measurements from NIFT were statistically different (P < 0.0001) from rectal thermometry. In addition, there was greater between- and within-subject variability in values using NIFT. There was no correlation between any sites of the NIFT and rectal thermometry. It was concluded that NIFT was not a valid alternative to rectal thermometry in cynomolgus macaques.

Glass-bulb Thermometer:
Glass-bulb thermometers are hollow glass tubes with a bulb tip containing liquid such as ethanol or mercury. Historically, glass bulb mercury thermometers were the standard device to measure body temperature. Today, mercury thermometers are prohibited in many countries due to the hazardous effects of mercury and the risk of exposure if the glass bulb breaks. In general,...
