Abstract
Aim: A
detailed histopathological examination of the
samples collected from morbid jungle crow was
performed to know the cause of death.
Materials
and Methods: Gross as well as histopathological
examination was conducted. The suspected tissues get
processed by formalin fixation and paraffin
embedding technique.
Result: On gross
examination, dry pox lesions were seen on the
external body surface whereas no internal lesions
were observed. However on histopathological
examination, the keratin layer of the epidermis was
found to be intact and there was extensive
proliferation of subdermal connective tissue
infiltrated with polymorph mononuclear (PMN) cells.
There was marked ballooning of keratinocytes.
Swollen keratinocytes had enlarged pleomorphic and
hyper-chromatic nuclei. Several keratinocytes also
showed presence of eosinophilic intracytoplasmic
inclusions (Bollinger bodies) which was considered
confirmatory.
Conclusion: Avipoxvirus
infection was noticed in a jungle crow. On
histopathological study, proliferation of subdermal
connective tissue, swollen keratinocytes,
pleomorphic and hyper-chromatic nucleus and
eosinophilic intracytoplasmic inclusions were
noticed.
