Sažetak

The objective of this study was to describe changes in the coagulation and fibrinolytic systems of Holstein-
Friesian (H-F) heifers infected naturally with Chlamydia spp. in Kazakhstan. Blood coagulation and morphology
tests were performed in 30 heifers, including 20 infected animals (experimental group I) and 10 clinically
healthy and uninfected animals (control group II). In the laboratory tests, the following blood parameters
were determined: prothrombin time (PT), activated partial thromboplastin time (APTT), thrombin time (TT),
antithrombin III activity (ATIII), fibrinogen (FBG), D-dimer (D-D) concentrations, thrombocyte counts (PLT)
and leukocyte counts (WBC). Decreased PT and APTT values in the blood plasma of heifers infected with
Chlamydia spp. were indicative of intensified procoagulant activity in such an acute infection. Increased ATIII
activity could point to the activation of the anticoagulant system to prevent excessive fibrin production in
diseased animals. The results indicate that the hemostatic system was activated in heifers with symptoms of
chlamydiosis, and regulatory mechanisms prevented the development of life-threatening conditions such as
thrombosis or disseminated intravascular coagulation (DIC).Śő
