Turkeypox Virus

Overview of Turkeypox

Turkeypox virus (TPV) is an enveloped double-stranded DNA virus with a large linear genome of approximately 300 kb in size. TPV is a member of the Poxviridae family and belongs to the genus Avianpoxvirus. There are other nine well-known species in the poxviridae family, including: fowlpox virus, juncopox virus, mynahpox virus, psittacinepox virus, sparrowpox virus, starlingpox virus, pigeonpox virus, canarypox virus, and quailpox virus.

Hot Topcis of Turkeypox Virus

• TPV has caused severe economic losses in meat contamination, weight loss, and reduced egg production in Indian turkey flocks.
• TPV is one of the highly contagious diseases infecting all ages, genders and breeds, and is caused by double-stranded DNA viruses belonging to the poxviridae and coronaviridae subfamily in the genus avipoxvirus with a genome size of 188.53 kb.
• Vaccination of turkey flocks with fowl pox vaccine has been routine in some areas for many years. Vaccine viruses are usually administered via the wing-net or thigh route.

Visual Examples of Turkeypox Virus

• All of the turkeys showed clinical symptoms, turkeys exhibit lethargy, loss of appetite, and lethargy. At necropsy, dead turkeys show numerous round to irregularly sized raised nodules (scabs) 1-3 cm in diameter on the skin around the head, eyelids, and beak.

• Histopathological examination of the crusts revealed epidermal hyperplasia and severe balloon degeneration, intracytoplasmic eosinophilic inclusions, and a sparse infiltration of inflammatory cells, with heterophiles predominant. Cytological examination revealed pink round inclusions in clear vacuoles.
