Volume 22 • Issue 03 • 2018 Figure 17: Mycotic dermatitis - facial Figure 18: Fetal heart failure with abdominal distention (arrow). Mycotic dermatitis (figure 16 & 17)- cutaneous lesions have a site predilection for periorbital areas, shoulders, back and flanks. Occasionally the fetus may aspirate organisms from the amniotic fluid initiating a bronchopneumonia. Endometrial lesions are less severe than in the placenta and usually long-term fertility of these animals is not affected. Fetal heart failure (figure 18) is associated with late stage abortion with gross external abnormalities of abdominal distention (ascites), with a fluid wave elicited on abdominal palpation. Primary differentials would include micronutrient imbalances, infectious myocarditis and mycotoxins. These findings would indicate that the fetus needs to be closely inspected for evidence of cardiac failure during the dissection and internal examination of the fetus. CPD AC/1942/18 1.

Which of the following is considered the most common cause of meconium staining of the fetus? a. Fetal pyrexia. b. Fetal hypoxia. c. Pyrexia of the dam. d. Endometritis. e. Placentitis. SMS code: a38356 3. Which of the following statements about hemoparasite induced abortion would be considered false? a. Abortion may occur following invasion of the fetus by hemoparasites. b. Maternal pyrexia does not cause abortion. c. Babesiosis is a significant cause of abortion in Africa. d. Anaplasmosis is a significant cause of abortion in Africa. e. Invasion of the fetus by hemoparasites induces fetal pathology. 4. Which of the following non-infectious causes of abortion can be associated with fetal arthrogryposis (contracted tendons)? a. Selenium deficiency. b. Mycotoxins. c. Prussic acid poisoning. 9
