Formative qs Flashcards
What are the most likely DDs in this sheep liver
hydatidosis (echinococcus granulosus) - most likely
Caseous lymphadenitis (Corynebacterium pseudotuberculosis)
Alveolar echinococcosis
Describe the zoonotic risk of hydatidosis
No zoonotic risk via direct contact with sheep
Risk is from contact with faeces of infected dogs (fed infected raw offal)
How can dogs be treated for hydatidosis to prevent zoonotic spread?
treat them monthly/every six weeks with praziquantel
A liver is rejected for hydatidosis on farm. What ABP category is this and why does this matter?
Cat 2
ABP legislation also applies to farm

What pathogens causes American Foulbrood in honey bees?
Paenibacillus larvae
What intervention strategy is the most effective in order to reduce the zoonotic risk posed by hydatidosis?
