Influenza B virus is almost exclusively a human pathogen, and is less common than influenza A. The only other animal known to be susceptible to influenza B infection is the seal . [ 47 ] This type of influenza mutates at a rate 2–3 times lower than type A [ 48 ] and consequently is less genetically diverse, with only one influenza B serotype ...

Canine distemper virus is closely related to measles virus and is the most important viral disease of dogs. The disease (which was first described in 1760, by Edward Jenner, the pioneer of smallpox vaccination, is highly contagious, but is well controlled by vaccination. In the 1990s, thousands of African lions died from the infection, which ...
MR is the process by which two, or more, virus genomes containing lethal damage interact within the infected cell to form a viable virus genome. Such MR was demonstrated for adenovirus 12 after virions were irradiated with UV light and allowed to undergo multiple infection of host cells. [ 25 ]
Bluetongue virus (BTV) is an Orbivirus that causes bluetongue disease in sheep, cattle, goats, and wild ungulates. BTV has been in the forefront of molecular studies for last three decades and now represents one of the best understood viruses at the molecular and structural levels.
A virus causing respiratory disease in humans has been called human bocavirus due to its similarity to these viruses. [3] Canine minute virus was originally discovered in Germany in 1967 in military dogs, [4] although it was originally thought to not cause disease. Dogs and puppies are infected orally, and the virus is spread transplacentally ...
It does this by making the cell copy the virus's DNA or RNA, making viral proteins, which all assemble to form new virus particles. [37] There are six basic, overlapping stages in the life cycle of viruses in living cells: [38] Attachment is the binding of the virus to specific molecules on the surface of the cell. This specificity restricts ...
In addition, five more species have recently been discovered: West Caucasian bat virus, Aravan virus, Khujand virus, Irkut virus and Shimoni bat virus. [8] [9] The lyssavirus genus can be divided into four phylogroups based upon DNA sequence homology. Phylogroup I includes viruses, such as Rabies virus, Duvenhage virus, European bat lyssavirus ...
