Trial for isolation and characterization of poxvirus from turkeys

Abstract: Turkeys showing lesion of pox infection were subjected to postmortem examination and samples were collected for isolation of the causative agent. An isolate was successfully recovered from the cutaneous pox lesions in embryonated chicken eggs. The isolate was tested in comparison with virulent fowl poxvirus for pathogenicity in susceptible birds ( turkey , fowls and ducks).
It was found that it produced pock lesion on the chorioallantoic membrane of ECE and specific takes at the site of inoculation by the wing-web method in fowls and ducks, and generalized proliferative nodules on the unfeathered parts of inoculated turkeys. On the other hand inoculated of fowl poxvirus in the same birds ( turkeys , fowls and ducks ) induced generalized pox lesions which appeared on turkeys and fowls , while the ducks did not produce any reaction. These results confirmed the identity of the isolate as turkeys poxvirus. Further confirmation that the isolate belongs to avian poxviruses was achieved by histopathological examination of samples collected from organs of experimentally infected turkeys and detection of the virus antigen in the organs of experimentally infected turkeys by the indirect fluorescent antibody technique.
