Introduction: Plasma cholinesterase activity levels of various species may be of interest to toxicologists or pathologists working with chemicals that interfere with the activity of plasma cholinesterase. Methods: We used a pH titration method to measure the plasma cholinesterase activity of six mammalian species. Results: Plasma cholinesterase activity varied up to 50-fold between species: sheep (88. ±. 45. nM acetylcholine degraded per ml of test plasma per minute), cattle (94. ±. 35), western grey kangaroos (126. ±. 92), alpaca (364. ±. 70), rats (390. ±. 118) and horses (4539. ±. 721). Discussion: We present a simple, effective technique for the assay of plasma cholinesterase activity levels from a range of species. Although labour-intensive, it requires only basic laboratory equipment.
