Cryptococcosis in domestic animals in Western Australia: a
retrospective study from 1995-2006.

School of Veterinary and Biomedical Sciences, Murdoch University,
Perth, Western Australia.
A retrospective study of cryptococcosis in domestic animals residing
in Western Australia was conducted over an 11-year-period (from 1995
to 2006) by searching the data base of Murdoch University Veterinary
Teaching hospital and the largest private clinical pathology
laboratory in Perth. Cryptococcosis was identified in 155 animals: 72
cats, 57 dogs, 20 horses, three alpacas, two ferrets and a sheep.
There was no seasonal trend apparent from the dates of diagnosis.
Taking into account the commonness of accessions to Murdoch
University, cats were five to six times more likely to develop this
disease than dogs, and three times more likely than horses, while
horses were almost twice as likely as dogs to become infected. Amongst
the feline cohort, Ragdoll and Birman breeds were over-represented,
while in dogs several pedigree breeds were similarly overrepresented.
Dogs and horses tended to develop disease at an early age (one to five
years), while cats were presented over a much wider range of ages. In
cats and dogs the upper respiratory tract was the most common primary
site of infection, while horses and alpacas tended to have lower
respiratory involvement. The most striking finding of the study was
the high frequency with which C. gattii was identified, with
infections attributable to this species comprising 5/9 cats, 11/22
dogs, 9/9 horses and 1/1 alpaca, where appropriate testing was
conducted. Preliminary molecular genotyping suggested that most of the
C. gattii infections in domestic animals (9/9 cases) were of the VGII
genotype. This contrasts the situation on the eastern seaboard of
Australia, where disease attributable to C. gattii is less common and
mainly due to the VGI genotype. C. gattii therefore appears to be an
important cause of cryptococcosis in Western Australia.

Adult deafness induces somatosensory conversion of ferret auditory
cortex.
Allman BL, Keniston LP, Meredith MA.
Department of Anatomy and Neurobiology, Virginia Commonwealth
University School of Medicine, Richmond, VA 23298.
In response to early or developmental lesions, responsiveness of
sensory cortex can be converted from the deprived modality to that of
the remaining sensory systems. However, little is known about capacity
of the adult cortex for cross-modal reorganization. The present study
examined the auditory cortices of animals deafened as adults, and
observed an extensive somatosensory conversion within as little as 16
days after deafening. These results demonstrate that cortical cross-
modal reorganization can occur after the period of sensory system
maturation.
