On the other hand, they show us how sophisticated and interconnected human beings have become. For example, experts estimate that the Mydoom worm infected approximately a quarter-million computers in a single day in January 2004. Back in March 1999, the Melissa virus was so powerful that it forced Microsoft and a number of other very large companies to completely turn off their e-mail systems until the virus could be contained.

There are many known diseases in humans caused by viruses, including, but not limited to, influenza, AIDS, and the common cold. Viruses also cause disease in other organisms besides humans, such as plants, insects, and bacteria. The process in which viruses cause disease is as follows: Viruses enter cells by connecting to a receptor on the cell's surface, and inject their genetic material (DNA or RNA), into the cell. The virus dies afterwards. The virus's genetic material travels to the nucleus, and becomes a part of the host cell's DNA. The virus's genetic material directs the host cell to produce copies of the virus. These copies burst from the host cell, killing the cell. These new viruses go on to infect other cells, creating more viruses. This cycle repeats itself over and over, causing disease. Structure The protein shell is the outer part of the virus.

What The Heck is a Virus? Introduction First, let me tell you what a virus is NOT. A virus is not a bacterium, nor an independently-living organism. A virus cannot survive in the absence of a living cell within which to synthesize copies of itself (replicate). Antibiotics do not harm a virus; it is for this reason that treatment for the "flu" for example, is mainly to help ease the symptoms of the illness rather than to kill the organism which causes the "flu" ( Influenza virus Please see: What the Heck is the "Flu"? Well then, what IS it? Now, is there a simple explanation which can define what a virus IS? Hmmmm... that's actually a tough question. A virus is not strictly alive.. nor is it strictly dead... A virus has some fundamental information (genes made of DNA or RNA) which allows it to make copies of itself. However, the virus must be inside a living cell of some kind before the information can be used. In fact, the information won't be made available unless the virus enters a living cell. It is this entrance of a virus into a cell which is called a viral infection. Too, the virus is very, very small relative to the size of a living cell. Therefore, the information the virus can carry is actually not enough to allow it to make copies (replicate). The virus uses the cell's machinery and some of the cell's enzymes to generate virus parts which are later assembled into thousands of new, mature, infectious virus which can leave the cell to infect other cells.

Rabies Virus Rabies virus The Rabies Virus is an organism that frightens many people. It causes the disease known as Rabies. Viruses are microscopic organisms, so you can't see them with your eyes. Other viruses you've probably heard of are flu viruses and AIDS. Scientists are still learning about viruses. They are not even sure where to put them when they organize other organisms, like plants and animals, into groups. Scientists have split viruses into Orders, Families, and Genera (genus). You can see which groups the Rabies Virus is put into at the bottom of the page. When scientists look at the Rabies Virus under a powerful microscope, they see that it is bullet-shaped (see pictures above). They also know it is covered with tiny spikes. The Rabies Virus is transmitted by saliva . It passes from one animal to another when the first animal bites the second animal. Once the Rabies Virus is in the blood, it attacks cells . The virus incubates , which means it grows and changes (a lot like a baby bird in an egg). Then it moves through the nerves, up the spinal cord, to the brain.

19. Introduction To The Viruses The capsid encloses either DNA or RNA which codes for the virus elements. While in this form outside the cell, the virus is metabollically inert; examples of such forms are http://www.ucmp.berkeley.edu/alllife/virus.html

Introduction to the Viruses In 1898, Friedrich Loeffler and Paul Frosch found evidence that the cause of foot-and-mouth disease in livestock was an infectious particle smaller than any bacteria. This was the first clue to the nature of viruses, genetic entities that lie somewhere in the grey area between living and non-living states. Viruses depend on the host cells that they infect to reproduce. When found outside of host cells, viruses exist as a protein coat or capsid , sometimes enclosed within a membrane. The capsid encloses either DNA or RNA which codes for the virus elements. While in this form outside the cell, the virus is metabollically inert; examples of such forms are pictured below. Viral micrographs : To the left is an electron micrograph of a cluster of influenza viruses, each about 100 nanometers (billionths of a meter) long; both membrane and protein coat are visible. On the right is a micrograph of the virus that causes tobacco mosaic disease in tobacco plants. When it comes into contact with a host cell, a virus can insert its genetic material into its host, literally taking over the host's functions. An infected cell produces more viral protein and genetic material instead of its usual products. Some viruses may remain dormant inside host cells for long periods, causing no obvious change in their host cells (a stage known as the lysogenic phase). But when a dormant virus is stimulated, it enters the
