pathology of various brain disorders in cattle. The data collected from the
autopsy records maintained at the Centre of Excellence in Pathology, Mannuthy
and fifty-two samples of brain obtained from both the slaughtered cattle and
autopsy cases formed the basis of the, study. Gross lesions were not so evident
except for the meningeal congestion, which accounted to 70 per cent of the
cases. Congestion and haemorrhages were found consistently in the slaughtered
cattle, which could be attributed to stunning effect. The other major lesions
were well appreciated by detailed histopathological examination of ten different
areas of the brain in each of the cases. These included vascular changes,
neuronal degeneration, inflammatory changes, gliosis, pigmentation and
neoplasia. Two cases revealed intra neuronal cytoplasmic inclusions of which
one was due to rabies and the other was attributedto viral etiology. Bovine
spongiform encephalopathy was not found to be present in any of the cases in
the present study. Based on the observations made here, it was suggested that
diagnosis of rabies by impression smear examination alone is not sufficient and
needs examination by FAT or Immunoperoxidase techniques. The incidence of
pathological disorders encountered was relatively high. Thus, the need and
scope for investigation into the pathological disorders of bovine brain were
highlighted.
