How does vaccinia virus replicate?
Vaccinia virus (VV) is an enveloped, double-stranded DNA virus of approximately 200 kb. This virus replicates in the cytoplasm, bringing with its infectious particle the enzymes required for DNA replication and transcription of its genes. VV has a broad host range.
Where does vaccinia virus replicate?
Vaccinia virus (vv), a member of the poxvirus family, is unique among most DNA viruses in that its replication occurs in the cytoplasm of the infected host cell.
Is adenovirus a DNA or RNA virus?
Adenoviruses are medium-sized (90-100 nm), non-enveloped icosohedral viruses with double-stranded DNA. More than 50 types of immunologically distinct adenoviruses can cause infections in humans.
Is Orthomyxovirus a DNA virus?
Unlike replication of other RNA viruses, orthomyxovirus replication depends on the presence of active host cell DNA. The virus scavenges cap sequences from the nascent mRNA generated in the nucleus by transcription of the host DNA and attaches them to its own mRNA.
Is monkey pox a virus?
What Is Monkeypox? A rare illness in the same family as smallpox, it happens when you’re infected with the monkeypox virus. Scientists first noticed the disease in 1958 in a group of lab monkeys used for research. Monkeypox has also been found in certain rodents and other primates in Africa.
What diseases does adenovirus cause?
Adenoviruses can cause a wide range of illnesses such as
- common cold or flu-like symptoms.
- sore throat.
- acute bronchitis (inflammation of the airways of the lungs, sometimes called a “chest cold”)
- pneumonia (infection of the lungs)
- pink eye (conjunctivitis)
Which disease is caused by Orthomyxovirus?
The orthomyxoviruses (influenza viruses) constitute the genus Orthomyxovirus, which consists of three types (species): A, B, and C. These viruses cause influenza, an acute respiratory disease with prominent systemic symptoms.
Why is it called Orthomyxovirus?
The family Orthomyxoviridae comprises the genera Influenzavirus A, Influenzavirus B, Influenzavirus C, Thogotovirus, Quaranjavirus, and Isavirus. The name of the family is derived from the Greek myxa, meaning mucus, and orthos, meaning correct or right.
Why is it called monkey pox?
Monkeypox was first discovered in 1958 when two outbreaks of a pox-like disease occurred in colonies of monkeys kept for research, hence the name ‘monkeypox.
Does monkey pox leave scars?
The rash begins as maculopapular lesions of 2-5 mm in diameter and spreads in a centrifugal pattern. The skin lesions progress through papular, vesicular, pustular, and crust phases over a period of 14-21 days. The lesions slough off and leave scars.
