what two viruses infect all vertebrates?
431204
Examples include, rabies, yellow fever and pappataci fever. The viruses that infect other vertebrates are related to those of humans and most families of viruses that cause human diseases are represented. They are important pathogens of livestock and cause diseases such as foot-and-mouth disease and bluetongue.

Rabies is a preventable viral disease most often transmitted through the bite of a rabid animal. The rabies virus infects the central nervous system of mammals, ultimately causing disease in the brain and death.

They must enter another virus structure. They must enter the cell of another organism. They must come in contact with water. They must encounter a virus with genetic material different from their own.

Bacteriophages inject DNA into the host cell, whereas animal viruses enter by endocytosis or membrane fusion. Animal viruses can undergo latency, similar to lysogeny for a bacteriophage.

The viruses cannot be transferred between animals and humans, and dogs cannot get parvovirus from cats, however a strain of canine parvovirus can infect cats.

CMV is related to the viruses that cause chickenpox, herpes simplex and mononucleosis.

Vertebrates are animals with backbones. This group includes reptiles, fish, amphibians, birds, and mammals. The world's biggest animal, the blue whale, is a vertebrate.

Avian influenza refers to the disease caused by infection with avian (bird) influenza (flu) Type A viruses. These viruses occur naturally among wild aquatic birds worldwide and can infect domestic poultry and other bird and animal species. Avian flu viruses do not normally infect humans.

Epstein-Barr Virus and Infectious Mononucleosis Epstein-Barr virus, or EBV, is one of the most common human viruses in the world. It spreads primarily through saliva. EBV can cause infectious mononucleosis, also called mono, and other illnesses.

Like other viruses, animal viruses are tiny packages of protein and nucleic acid. They have a protein shell, or capsid, and genetic material made of DNA or RNA that's tucked inside the caspid. ... Animal virus genomes consist of either RNA or DNA, which may be single-stranded or double-stranded.

Plant viruses (Phytophages) principally attack plants and majority of them possess single stranded RNA. Plant viruses or reoviridae contain of RNA as genetic material. ... Animal viruses (Zoophages) are those viruses that principally attack animals and possess double stranded DNA.

Epizootic Hemorrhagic Disease (EHD) is a virus that affects domestic and wild hoofed animals. It is transmitted by the bite of a small midge (culicoides) known as “no-see-ums,” gnats and biting flies smaller than a mosquito. They transmit the virus by biting an infected host and then a susceptible one.

Researchers have found that henipaviruses, which spread to other animals and humans, and a disease that is similar to rabies are widespread in a species of fruit bat found in Africa. The team says this poses a potential risk to human health, because the bats roost close to cities and are also hunted for food.

All viruses contain the following two components: 1) a nucleic acid genome and 2) a protein capsid that covers the genome. Together this is called the nucleocapsid. In addition, many animal viruses contain a 3) lipid envelope. The entire intact virus is called the virion.
