Yes, the majority of viruses are very species specific. There are exceptions however, such as rabies. Most viruses will not survive for long beyond their host tissue environment.
Because viruses and the attachment sites of the host cell must math exactly, like a puzzle.
Some affect many different cells and some affect only one or two.
A viral species means that it is caused by a virus, which is non-living and contains genetic material within a protein capsule. Most viruses are not treated because unlike bacterial species, there is no antibiotics even though specific viruses can be treated with certain chemicals.
The grouping of viruses is based on the particular species. Viruses are also living organisms which are divided into specific genus and species.
viruses must bind precisely to proteins on the cell surface and than use a hosts genetic system, this is why most viruses are highly specific to the cells they infect
The most specific level of taxonomy is species.
somehow
Viruses attack animals, plants, fungi, protists, and bacteria. Some viruses can infect only specific kinds of cells. For instance, many viruses, such as the potato leaf-roll virus, are limited to one host species or to one type of tissue within that species. A few viruses affect a broad range of hosts. An example of this is the rabies virus. Rabies can infect humans and many other animal hosts.
species
The species level is the smallest and most specific classification level in the taxonomic hierarchy. Organisms within a species share similar traits and can interbreed to produce fertile offspring.
Since viruses are not alive, they are not named by a genus or a species.
Species is the most specific group in taxonomy with Kingdom being the broadest group.
viruses are specific to the cells they infect called host cells
kingdom is the most specific classification category i found this out in my science book chapter 7 Improved answer: species and genus after because some species are categorized into sub-species The answer is in your question, the most specific is species. The word specific is actually a newer word based on species, from the Latin "specificus"- constituting a species. Specific is generally defined as limited, involving or relating to only one particular thing or type of thing. In biology specific is defined as refering to characteristics limited to a species. The use of sub-species as being more specific is problematical as a suspecies may be discontinued if the differences defining the sub-species are determined to be minor and the sub-species is returned to the species, or the differences so great that the sub-species is given a species of its own.
