Comparison of rectal and tympanic core body temperature measurement in adult Guyanese squirrel monkeys (Saimiri sciureus sciureus)

Abstract

The tympanic thermometer designed for use in humans can be used in adult squirrel monkeys as an alternative to rectal thermometry for assessing core body temperature.

Relationship between body temperature, weight, and hematological parameters of black tufted‐ear marmosets (Callithrix penicillata)

“…In our captive adult black tufted‐ear marmosets, basal thermal values obtained via RC and SC routes were significantly higher than those recorded at the left and right TM. The former two had equivalent temperature ranges and were similar to values reported for neotropical primates, including marmosets . RC data reflect deep body temperatures, which in turn are usually higher than those detected at more superficial levels [e.g., ].…”

“…It is also important to point out that the thermal values recorded at the left and right TM were similar in range, yet lower than previous reports for this species . While the former result initially suggests a symmetrical cerebral activation during the procedure , pre‐capture baseline TM temperatures are not available and thus individual differences may confound this effect . In addition, the individuals assessed in the present study have an extensive capture and manipulation history due to clinical and experimental procedures (>20 events), which may have led to higher neural activation, brain temperatures, and blood flow, and thus lower TM temperatures .…”

“…In non‐human primates (NHP), as with most mammals, rectal (RC) thermometry is the most commonly used method to estimate core body temperature . This is an inexpensive and minimally invasive technique, yet it is also time‐ and labor‐consuming to perform, may inflict local injury particularly during repeated samplings, and commonly induces handling stress or requires the use of sedatives/anesthetics that alters baseline measurements . Alternatively, body temperature measured via easily implantable subcutaneous (SC) microchip transponders is a less invasive method that correlates with rectal temperatures of NHPs [; however, see ] and other animals [e.g., ].…”

Agreement between auricular and rectal measurements of body temperature in healthy cats

“…In veterinary medicine, auricular thermometry has been investigated in several species, including dogs, cats, non-human primates and various other laboratory animals. 5,8,9,15,16 In general, these studies indicate that animals tend to tolerate the use of these devices more readily than rectal thermometers. However, the results regarding correlation with an established method of measuring temperature are somewhat contrasting.…”

“…7 Studies in veterinary medicine have demonstrated contrasting results, 1,5,8,9 with the majority of them concluding that auricular and rectal temperatures cannot be used interchangeably.…”
