Cause Hendra. Equine Mobillivirus (EMV); member of family<br />

Paramyxoviridae which was initially called Equine Mobilivirus or<br />

EMV.<br />

Signs First discovered in 1996 when the Department of Primary<br />

Industries was researching a virus that killed two humans and a<br />

number of horses in 1994. The affected died after contracting an<br />

influenza type illness, resulting in pneumonia, respiratory and<br />

renal failure. It is not considered to be highly contagious. No<br />

gross pathology or history of attributable illness has been<br />

detected in FFs. GHFF do not appear ill with this virus.<br />

Diagnosis <strong>Flying</strong> <strong>Fox</strong> to Horse to Human. Only confirmed by histological<br />

examination after death using indirect immunofluourescence test.<br />

Treatment None known.<br />

Prevention Regular testing of captive population – segregate from wild<br />

population.<br />

Cause Menangle – Paramyxovirus – first observed in stillborn piglets.<br />

Signs Symptoms similar to severe influenza – not known how it affects<br />

FFs.<br />

Diagnosis Blood tests <strong>for</strong> antibodies.<br />

Treatment Not known at this time.<br />

Prevention Not known at this time.<br />

Wing Damage<br />

Inspection Technique<br />

Damage to the wing membrane is generally<br />

repairable with time, however, GHFFs have<br />

a tendency to self-mutilate whenever the<br />

wing membrane is damaged so an<br />

Elizabethan collar may be need to be<br />

applied in cases of severe wing membrane<br />

damage (Bellamy-T and pers obs). (Refer<br />

Annexure 13 <strong>for</strong> template). Any tear to the<br />

leading edge of the Propatagium may<br />

render the GHFF unable to fly, and as this<br />

controls the ability of their ability to close the<br />

wing properly, euthanasia may need to be<br />

considered.<br />

Turner-B discusses the complex nature of the FF wing when he notes:<br />

“The bone is thin and highly fragmented, the humerus has a decided curve to it,<br />

the integrity of which is important to maintain <strong>for</strong> functional flight.<br />

The radius is difficult to pin. The radial nerve is highly vulnerable to damage from<br />

attempting a retrograde pinning, that is, introducing the pin into the fracture site,<br />

pushing it out through the elbow and then pushing it back into the other side of<br />

the bone”. (p1)<br />
