Virus Virus Definition noun, plural: viruses A submicroscopic infectious agent that is unable to grow or reproduce outside a host cell . It is non- cellular but consisting of a core of DNA or RNA surrounded by a protein coat. Supplement A virus requires a living cell for it to grow and reproduce similar to an obligate intracellular parasite . Many viruses can cause disease in host organisms but not all can cause disease . The first known virus, tobacco mosaic virus , was discovered by Martinus Beijerinck in 1899. Viruses may be classified based on their type of genome Baltimore classification Class I dsDNA viruses , i.e. with double stranded DNA genome Class II ssDNA viruses , i.e. with single stranded DNA genome Class III dsRNA viruses , i.e. with a double stranded RNA genome Class IV ssRNA viruses , i.e. with a positive sense, single stranded RNA genome , the genome itself acting as mRNA Class V ssRNA viruses , i.e with a negative sense, single stranded

Created by George Rice , Montana State University "Viruses straddle the definition of life. They lie somewhere between supra molecular complexes and very simple biological entities. Viruses contain some of the structures and exhibit some of the activities that are common to organic life, but they are missing many of the others. In general, viruses are entirely composed of a single strand of genetic information encased within a protein capsule. Viruses lack most of the internal structure and machinery which characterize 'life', including the biosynthetic machinery that is necessary for reproduction. In order for a virus to replicate it must infect a suitable host cell". From The Bacteriophage T4 Virus Virus Definition: What is a Virus? Background: When researchers first discovered agents that behaved like bacteria but were much smaller and caused diseases such as rabies and foot-and-mouth disease, it became the general view that viruses were biologically "alive." However this perception changed in 1935 when the tobacco mosaic virus was crystallized and it was shown that the particles lacked the mechanisms necessary for metabolic function. Once it was established that viruses consist merely of DNA or RNA surrounded by a protein shell, it became the scientific view that they are more complex biochemical mechanisms than living organisms.

West Nile Virus Submitted by: Guru: Contains Exact Advanced Search ON OFF This Pathway: West Nile virus (WNV) is a member of the Flaviviridae, a plus-stranded virus family that includes St. Louis encephalitis virus, Kunjin virus, yellow fever virus, Dengue virus, and Japanese encephalitis virus. WNV was initially isolated in 1937 in the West Nile region of Uganda and has become prevalent in Africa, Asia, and Europe. WNV has rapidly spread across the United States through its insect host and causes neurological symptoms and encephalitis, which can result in paralysis or death. Since 1999 about 3700 cases of West Nile virus (WNV) infection and 200 deaths have been recorded in United States. The viral capsid protein likely contributes to the WNV-associated deadly inflammation via apoptosis induced through the mitochondrial pathway. Joseph Chuang, PhD Blackwell JL, Brinton MA.

While commonly thought of as a Windows -only problem, they do not as a whole discriminate between platforms, and there is no platform for which a virus cannot be coded.

Geek Gifts virus A software program that replicates on computer systems by incorporating itself into shared programs. Viruses range from harmless pranks that merely display an annoying message to programs that can destroy files or disable a computer altogether. Whether they're considered malicious or malevolent, all viruses spread rapidly. For example, from one computer to millions of others around the world, infecting machines and causing them to crash . Some well-known examples include the "I Love You" virus, code red, and NIMDA. Viruses are most commonly transmitted through e-mail ; "strains" have appeared that use personal e-mail address books to propagate themselves from machine to machine. If you are connected to the Internet or any other network , it is important that you take precautions against viruses. Get a virus-scanning program and do not open any e-mail attachments from people you do not know. One tech support woman told me, "It may sound silly but get in the habit of scanning your computer from your anti-virus software's Web site because sometimes malware can hide but if you do it from their Web site it can't hide." VIRUS TIP: To avoid spreading computer viruses via e-mail, create a contact in your e-mail address book with the name !0000 (an exclamation mark and four zeros) and no e-mail address in the details. This contact will then show up as your first contact. If a virus attempts to do a "send all" to your contact list, your computer will put up an error message saying, "The message could not be sent. One or more recipients do not have an e-mail address. Please check your address book and make sure all the recipients have a valid e-mail address." The offending message (with the virus) may then be automatically stored in your Drafts or Outbox folder. Go in there and delete the offending message. (This is not a substitute for virus protection software, and it will not protect you from getting a virus, but it will prevent your computer from sending the virus to everyone on your contact list. Note: This trick may not work on AOL.)
