[Cholinesterase activity of sperm from rams infected with Brucella ovis].

Studied were the indices of cholinesterase activity of semen taken from 23 normal rams and 23 rams infected with Brucella ovis, the latter being positive by the complement-fixation test and showing a varying deterioration of the semen production. The results obtained were processed biometrically. Established were dependable differences. The cholinesterase activity of semen of brucellosis-affected rams proved four times higher than that of normal rams' semen: 39.45 +/- 5.49 microleter TO2 for 1 hour as against 174.15 +/- 9.97 microleter. A reverse correlation was established between the values of the cholinesterase activity, and the pH value and the percent of pathologic forms of spermatozoa.
