Practice exam questions
Ǫuestion 1 (12 minutes/ 10 marks)
Australia classifies itself as ‘rabies-free’, yet a few international virologists question
whether this is strictly correct. Explain the basis for this ambiguity and explain in what
way the practical manifestation of any rabies-like disease is very different in Australia to
countries overseas where rabies is generally classified as endemic.
Answer guidance/key points for response:
• Australia has the Australian bat lyssavirus
• Bats are the reservoir host
• The virus is genetically very close to the rabies virus, and the outcome of human
infection is the same
• Administration of standard rabies vaccine appears protective against Australian bat
lyssavirus in humans
• The virus/disease does behave differently to (classical) rabies in some important
respects:
, — Human infection is incredibly rare – only 3 people are known to have been
infected
— All 3 people are understood to have become infected through direct contact
(bite, scratch) from bats
— Thus – there is no transmission via other affected animals (e.g. dingos), and
no sustained transmission among wildlife or domestic dogs to provide an
ongoing human and animal risk
— (Two horses are known to have been infected)
Ǫuestion 2 (12 minutes/ 10 marks)
For several years, Victoria had ‘breed-specific’ legislation, armed at reducing the risk of
aggressive acts by dogs towards humans or other dogs by placing restrictions on certain
breeds. These laws have now been replaced. Explain why breed-specific legislation may
be relatively ineffective at addressing issues of severe dog aggression.
Answer guidance/key points for response:
• Breeds exist as a continuum within the one species, and it can be difficult or
impossible to determine the ‘breed’ of a particular animal.
— For some breeds, no agreed ‘breed standards’ exist
• Dog aggression is linked to many factors – and environmental inffuences (previous
experience etc) are strong
— there may be behavioural differences between breeds, but we have not
discovered major genes for aggression
