The activity of a catalythic centre of brain acetylcholine esterase (AChE, EC 3.1.1.7), serum choline esterase (ChE, EC 3.1.1.8) and liver choline esterases (AChE, ChE) of rats, livestock as well as the protein contents in their brain and liver were assessed. It was proven that the differences in catalythic centre for serum ChE were statistically significant (exepting ChE of rats and sheep). The catalythic centre differences for brain AChE were significant in only 12 cases and insignificant in the remaining 24 cases. This conclusion confirmed and enlarged the conclusions of a number of authors who support mainly that there exists a similarity of many properties of AChE, which was evident from investigations of the enzyme from different, mainly laboratory, animals. The possibility has been discussed that the established correlation between brain AChE activity and the animals' resistance to organophosphates May be used as a criterion for introducing new organophosphate insecticides.
