Dear Dr Mason,

I understand that you have experience with the life cycles and pathology
associated with infestation with both Paralephostrongylus tenuis and
Elaphostrongylus cervi.  Recently, we necropsied a recumbent llama on
histoptahology, an extensive haemorrhagic and necrotising leucomyelopathy
was found in the spinal cord from which nematode-like larvae were identified
in the white matter.  I understand tha P. tenuis have been known to cause
this condition in North America, but as we have no white-tailed deer in the
UK, I am unsure as to whether this is likely to be the parasite involved.
We certainly have red deer and E. cervi is known to infest them here.  Is E.
cervi ever recorded as having infested llamas?

Any advice you can give would be very much appreciated.

Yours sincerely,
