  • Primerjava aktivnosti pepsinogena v serumu govejih pitancev, pozitivnih na enzootsko govejo levkozo (EGL), in krav s čirom na siriščniku = Comparison of serum pepsinogen activity between enzootic bovine leukosis (EBL) positive beef cattle and cows with abomasal ulcers

    Serological positive reaction to enzootic bovine leukosis (EBL) were established by means of agar- gel- imunodiffusion tests applied to 25 beef cattle. The pepsinogen activity in the ... serologically-positive sera was determined by using Paynters method. The results were compared with those froma group of 30 clinically healthy EBL negative young cattle and those from a group of 10 animals with pathoanatomical abomasal ulcers. Although not statistically significant, the mean pepsinogen activity in the sera of the EBL-positive beef cattle was higher (3.35 +- 2.31 U/L) than in the control group of EBL-negative animals (2.45 +- 1.00 U/L). The sera of the group of animals with abomasal ulcers had statistically significant higher mean value of pepsinogen (6.48 +- 1.80 U/L) than both the control and EBL-positive groups. A comparison of the established mean pepsinogen values confirmed that EBL-associated lymphosarcoma-related alternations on the abomasal mucosa were not manifested in the majority of the younger animals.
