3D still showing rabies virus structure. Rhabdoviruses have helical symmetry, so their infectious particles are approximately cylindrical in shape. They are characterized by an extremely broad host spectrum ranging from plants [citation needed] to insects [citation needed] and mammals; human-infecting viruses more commonly have icosahedral symmetry and take shapes approximating regular polyhedra.
Lyssavirus (from the Greek λύσσα lyssa "rage, fury, rabies" and the Latin vīrus) [1] [2] is a genus of RNA viruses in the family Rhabdoviridae, order Mononegavirales. Mammals, including humans, can serve as natural hosts. [3] [4] The genus Lyssavirus includes the causative agent (rabies virus) of rabies. [5]
In the lytic cycle, the viral DNA exists as a separate free floating molecule within the bacterial cell, and replicates separately from the host bacterial DNA, whereas in the lysogenic cycle, the viral DNA is integrated into the host genome. This is the key difference between the lytic and lysogenic cycles.
Viruses may undergo two types of life cycles: the lytic cycle and the lysogenic cycle. In the lytic cycle, the virus introduces its genome into a host cell and initiates replication by hijacking the host's cellular machinery to make new copies of the virus. [12] In the lysogenic life cycle, the viral genome is incorporated into the host genome.
The Gammaherpesvirinae subfamily is associated with episomal latency established in cells of the immune system, such as B-cells in the case of Epstein–Barr virus. [3] [4] Epstein–Barr virus lytic reactivation (which can be due to chemotherapy or radiation) can result in genome instability and cancer. [5]
Lysogenic cycle, compared to lytic cycle Lysogenic Cycle:1. The prokaryotic cell is shown with its DNA, in green. 2. The bacteriophage attaches and releases its DNA, shown in red, into the prokaryotic cell. 3. The phage DNA then moves through the cell to the host's DNA. 4. The phage DNA integrates itself into the host cell's DNA, creating ...
Temperate phages can switch between a lytic and lysogenic life cycle. Lytic is more drastic, killing the host whereas lysogenic impacts host cells genetically or physiologically. [4] [5] [6] Here is a chart on temperate phages that are lytic and lysogenic and how they're related. Lysogeny is characterized by the integration of the phage genome ...
[2] [3] [4] Diseases associated with member viruses include rabies encephalitis caused by the rabies virus, and flu-like symptoms in humans caused by vesiculoviruses. The name is derived from Ancient Greek rhabdos, meaning rod, referring to the shape of the viral particles. [5] The family has 40 genera, most assigned to three subfamilies. [6]
