| Abstract: | Acute disseminated intravascular coagulation (DIC) was diagnosed in a 3 1/2 year old cow of the Simmental breed. The cow was little less than 6 months pregnant and was admitted to the clinic because of severely disturbed general health. The most important clinical findings were increased heart and breathing rate, rectal temperature of 39.9 degrees C, nosebleed and petechiae on the nasal mucosa. Additionally, the cow showed petechiae on the vaginal mucosa, haemorrhage from the rectum lasting several hours after rectal examination and severe haemoglobinuria. Haematological and biochemical examinations showed increased liver enzymes and severe changes in all coagulation parameters (platelet count, PT, PTT, thrombin time, fibrinogen, fibrin degradation products). Based on the mentioned findings the diagnosis DIC was made. Possible causes were severe necrotic endometritis and placentitis combined with fetal death. High counts of Escherichia coli and Clostridium perfringens were determined in liver, lung and abomasal contents of the aborted fetus as well as in the placenta. Uterine secretion contained Actinomyces pyogenes besides. |
