In animals, rabies is a viral zoonotic neuro-invasive disease which causes inflammation in the brain and is usually fatal. Rabies, caused by the rabies virus, primarily infects mammals. In the laboratory it has been found that birds can be infected, as well as cell cultures from birds, reptiles and insects. [1]
Rabies is infectious to mammals; three stages of central nervous system infection are recognized. The clinical course is often shorter in animals than in humans, but result in similar symptoms and almost always death. The first stage is a one- to three-day period characterized by behavioral changes and is known as the prodromal stage. The ...
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.

If the animal is caught alive or dead with its head preserved, the head can be analyzed to detect the disease. Signs of rabies include foaming at the mouth, growling, self-mutilation, jerky behavior, red eyes, and hydrophobia. If the animal cannot be captured, preventative rabies treatment is recommended in many places.
The most common signs are facial swelling and hives, but more rarely very serious signs such as hypotension and collapse may occur. [ 187 ] Systemic lupus erythematosus (SLE) is an immune system disease characterized by the presence of antibodies to nucleic acid and/or antibodies to red blood cells , platelets , lymphocytes , clotting factors ...
The mammalian disease rabies is caused by lyssaviruses, of which several have been identified. Rhabdoviruses are important pathogens of animals and plants. Rhabdoviruses are transmitted to hosts by arthropods, such as aphids, planthoppers, leafhoppers, black flies, sandflies, and mosquitoes.
Companion animals such as cats, dogs, and horses, if not vaccinated, can catch serious viral infections. Canine parvovirus 2 is caused by a small DNA virus, and infections are often fatal in pups. [12] The emergence of the parvovirus in the 1970s was the most significant in the history of infectious diseases.
