Question 1

Answer 1

Pyometra

Question 2

Answer 2

Coliform mastitis glandular necrosis and marked subcutaneous oedema

Question 3

Answer 3

Question 6

What is Taylorella equigenitalis and what disease does it cause?

Answer 6

• Gram negative bacteria
• Causative agent of Contagious equine metritis (CEM) in mares
• Stallions are asymptomatic carriers

Question 7

Uterine contamination with commensals or pathogens is common postpartum in which species?

Answer 7

All species

Question 8

Uterine contamination with commensals or pathogens is common post-mating in which species?

Answer 8

Only in species with no mucus plug over the cervix, where ejaculation occurs directly into the uterus

• Mare
• Sow
• Bitch

Question 9

True/false: the mare, sow and bitch can develop mating induced endometritis.

Answer 9

True.

• They can also develop endometritis without mating if bacteria ascend through the open cervix during oestrus.

Question 10

How do commensal organisms infiltrate the uterus postpartum? How does metritis develop?

Answer 10

• As the placenta detaches, deeper layers of the uterus are exposed
• Commensals can infiltrate the endometritis
• When the organisms penetrate deeper layers (myometrium) this becomes metritis
