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]
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.
Rabies is caused by lyssaviruses, including the rabies virus and Australian bat lyssavirus. [4] It is spread when an infected animal bites or scratches a human or other animals. [1] Saliva from an infected animal can also transmit rabies if the saliva comes into contact with the eyes, mouth, or nose. [1]
Vertebrates (including mammals and humans), invertebrates, plants, fungi and protozoans serve as natural hosts. [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.
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]
The Summary. A new study describes how bird flu has spread between dairy cows and from cows to other mammals. Experts worry the virus is developing new capabilities that could help it evolve to ...
The H5N1 virus could be spread through cats' saliva, feces or other body fluids. All the people who caught it were exposed on farms and fully recovered, and officials are working to reduce the spread.
Viruses of the taxon Ebolavirus, which causes Ebola virus disease, are thought to have a natural reservoir in bats or other animals exposed to the virus. [9] Other zoonotic diseases that have been transmitted from animals to humans include: rabies , blastomycosis , psittacosis , trichinosis , cat-scratch disease , histoplasmosis ...
