Animal viruses are viruses that infect animals. Viruses infect all cellular life and although viruses infect every animal, plant, fungus and protist species, each has its own specific range of viruses that often infect only that species.
The variety of host cells that a virus can infect is called its host range: this is narrow for viruses specialized to infect only a few species, or broad for viruses capable of infecting many. [13]: 123–124 Viral infections in animals provoke an immune response that usually eliminates the infecting virus.
[2] [7] In Rabiesvirus, the incubation period varies with the distance traversed by the virus to the target organ; but in most viruses the length of incubation depends on many factors. [7] [28] Surprisingly, generalised infections by togaviruses have a short incubation period due to the direct entry of the virus into target cells through insect ...
An analysis of all the publicly available viral genome sequences yielded a surprising result: humans give more viruses - about twice as many - to animals than they give to us. Of those, 79% ...
This specificity restricts the virus to a very limited type of cell. For example, the human immunodeficiency virus (HIV) infects only human T cells, because its surface protein, gp120, can only react with CD4 and other molecules on the T cell's surface. Plant viruses can only attach to plant cells and cannot infect animals.
And on Dec. 23, more than 40 outbreaks of the virus were reported by the Minnesota Department of Health. Although it’s commonly called the stomach flu due to the shared symptoms, norovirus isn ...
Genetically modified viruses that make the target animals infertile through immunocontraception have been created [33] as well as others that target the developmental stage of the animal. [34] There are concerns over virus containment [33] and cross species infection. [35]
Cross-species transmission is the most significant cause of disease emergence in humans and other species. [citation needed] Wildlife zoonotic diseases of microbial origin are also the most common group of human emerging diseases, and CST between wildlife and livestock has appreciable economic impacts in agriculture by reducing livestock productivity and imposing export restrictions.
