Poxviruses are enveloped, linear, double-stranded DNA viruses in the order Caudovirales and family Poxviridae
. Poxviruses are the largest and most complex of all viruses and are divided into two subfamilies: the Chordopoxvirinae (with eight genera) and the Entomopoxvirinae (with three genera).
Avipoxviruses (family Poxviridae
) enter the body through a break in the mucous membrane or skin and cause disease that has 1 of 3 main presentations: dry (cutaneous), wet (dipththeretic), and systemic.

Avipoxviruses are large, enveloped DNA viruses that belong to the genus Avi poxvi rus in the Chordopoxvirinae subfamily of the family Poxviridae
. These viruses cause disease in a large number of bird species and are generally named after the species from which the virus was first isolated and characterized (1).
Vaccinia virus (VACV) is the prototype member of the family Poxviridae
, genus Orthopoxvirus, whose infection results in vesiculopustular and scab lesions, mainly in cattle and man (BULLER & PALUMBO, 1991).
Nucleotide sequence comparison of a polymerase chain reaction amplified 4.5 kb HindIII fragment of the genome of flamingo poxvirus (F1PV) revealed very high homology (99.7%) with condor poxvirus (CPV), followed by approximately 92% similarity with canary poxvirus (CNPV) and Hawaiian goose poxvirus (HGPV), but less similarity (approximately 69%) to fowl poxvirus (FPV), the type species of the genus Avipoxvirus of the family Poxviridae
. As in the cases with CPV, CNPV, and HGPV, genetic analysis of F1PV revealed an absence of 3 corresponding FPV open reading frames (ORF199, 200, and 202) and an absence of any reticuloendotheliosis virus (REV) sequences in this region.
family comprises large double-stranded DNA viruses that infect a wide range of invertebrate and vertebrate animals, including humans (1).
Orthopoxviruses (family Poxviridae
, genus Orthopox-virus) cause several zoonotic diseases worldwide, including diseases caused by monkeypox virus in Africa, cowpox virus mainly in Europe, and vaccinia virus (VACV) in South America and Asia (1).

Kaposi sarcoma was suspected initially, but on hospital day 5, a skin biopsy showed large intracellular eosinophilic inclusion bodies pathognomonic for infection with cowpox virus (family Poxviridae
, genus Orthopoxvirus).
