Abstract:
A confirmatory diagnosis of turkey pox was done based on clinical signs and symptoms. A total of 10 poults were investigated and clinical specimens for histopathology as well as scab lesions were collected from clinically suspected field cases for molecular detection of turkey pox. Histopathological examination, Polymerase chain reaction (PCR) and Gene sequencing was performed for confirmatory diagnosis. External gross lesions of infected turkey birds showed cutaneous lesions mainly nodular, papular, pustular, erosion during diseased condition and crust lesions at recovery stages mainly around the eye, head, wattle, snood, beak and neck. All histopathological observation includes infiltration of inflammatory cells. The most pathognomonic histopathological lesions intracytoplasmic inclusions bodies (Bollinger bodies) were found. Outbreak samples gave positive for PCR test of turkey pox virus and phylogenitic analysis revealed 99.9% of homology with other Indian strain of the virus.
