Smallpox replication cycle

WebVariola is a highly infectious member of the DNA poxvirus family. Smallpox disease is characterized by pain, fever, and a severe blistering of the skin that leaves disfiguring marks, particularly on the face of the infected individual (refer to Plate 1-1 ). Smallpox infection is fatal in 30% of cases. WebPoxvirus replication takes place in cytoplasmic inclusions. Infecting virions are partly uncoated by cellular enzymes and then fully uncoated by viral enzymes released from the …

Poxviruses include the Variola virus, which causes smallpox, a highly infectious and deadly disease.

WebIntermediate phase: Intermediate genes are expressed, triggering genomic DNA replication at approximately 100 minutes post-infection. Late phase: Late genes are expressed from 140 min to 48 hours post-infection, producing all structural proteins. WebReplication of the poxvirus is accomplished in several stages. Initially, the virus binds to a receptor present on the surface of host cell. So far the receptors for the poxvirus are not …

WebSeveral stages are involved in the replication of poxviruses. First, the virus bind to the receptor on the host surface; Glycosaminoglycan’s (GAGs) is supposed to be the receptors of the pox virus. After the virus attached to the receptor on the surface of the host cell, it forced to enter to cytoplasm and removal of its coating takes place. WebPoxviruses are large, enveloped viruses that replicate in the cytoplasm and encode proteins for DNA replication and gene expression. Hairpin ends link the two strands of the linear, double-stranded DNA genome.

WebPoxviruses can reproduce only within a host cell. The infection process produces many progeny that are replicas of the parent virus. The first step in the cycle of infection is attachment of the invading virion to the surface of …
