Immune modulation by virus-encoded secreted chemokine binding proteins [PDF]
Chemokines are chemoattractant cytokines that mediate the migration of immune cells to sites of infection which play an important role in innate and adaptive immunity. As an immune evasion strategy, large DNA viruses (herpesviruses and poxviruses) encode

Orthopoxvirus Genes That Mediate Disease Virulence and Host Tropism
In the course of evolution, viruses have developed various molecular mechanisms to evade the defense reactions of the host organism. When understanding the mechanisms used by viruses to overcome manifold defense systems of the animal organism ...

Terminal Region Sequence Variations in Variola Virus DNA
Genome DNA terminal region sequences were determined for a Brazilian alastrim variola minor virus strain Garcia-1966 that was associated with an 0.8% case-fatality rate and African smallpox strains Congo-1970 and Somalia-1977 associated with variola major (9.6%) and minor (0.4%) mortality rates, respectively.

In vitro characterization of a nineteenth-century therapy for smallpox.
In the nineteenth century, smallpox ravaged through the United States and Canada. At this time, a botanical preparation, derived from the carnivorous plant Sarracenia purpurea, was proclaimed as being a successful therapy for smallpox infections.

Time scale evolution of avipoxviruses [PDF]
Avipoxviruses are divided into three clades: canarypox-like viruses, fowlpox-like viruses, and psittacinepox-like viruses. Several molecular clock and demographic models available in the BEAST package were compared on three avipoxvirus genes (P4b ...

Alastrim Smallpox Variola Minor Virus Genome DNA Sequences
Alastrim variola minor virus, which causes mild smallpox, was first recognized in Florida and South America in the late 19th century. Genome linear double-stranded DNA sequences (186,986 bp) of the alastrim virus Garcia-1966, a laboratory reference strain from an outbreak associated with 0.8% case fatalities in Brazil in 1966, were determined except ...

Smallpox Infectious Disease [PDF]
Smallpox is a disease similar to chicken pox, but not exactly the same. Smallpox is caused by a virus called Variola and is a member of the genus orthopoxvirus. The virus is a large brick shaped DNA virus. Smallpox spreads by direct, face to face contact
