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 ...
Like other members of the Paramyxoviridae family, it produces enveloped virions, and is a negative-sense single-stranded RNA virus. The virus is particularly fragile and is quickly inactivated by heat, desiccation, and sunlight. [14] Measles virus evolved from the then-widespread rinderpest virus most probably between the 11th and 12th ...
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 ...
Polyomaviridae is a family of viruses whose natural hosts are primarily mammals and birds. [1] [2] As of 2024, there are eight recognized genera. [3]Fourteen species are known to infect humans, while others, such as Simian Virus 40, have been identified in humans to a lesser extent.
Sheeppox virus is an aerosol and can also be transmitted via contact with an infected animal. The saliva, secretions, feces, milk or scabs of those with SPV also cary the virus. Contaminated equipment is another major transmission factor and insect vectors play a minor role. SPV is mainly spread to new areas due to the movement of infected ...
The International Committee on Taxonomy of Viruses (ICTV) authorizes and organizes the taxonomic classification of and the nomenclature for viruses. [1] [2] [3] The ICTV develops a universal taxonomic scheme for viruses, and thus has the means to appropriately describe, name, and classify every virus taxon.
Fowlpox virus Fowlpox is the worldwide disease of poultry caused by viruses of the family Poxviridae and the genus Avipoxvirus . The viruses causing fowlpox are distinct from one another but antigenically similar, possible hosts including chickens , turkeys , quail , canaries , pigeons , and many other species of birds.
The virus is spread through milk, saliva, ocular secretions, and nasal secretions, and has been shown to remain virulent outside of a host for four months. [6] The camelpox virus has been isolated from camel ticks (Hyalomma dromedarii) removed from infected animals. It is believed that the ticks can transmit the disease from camel to camel.
