A virus is a small infectious agent that replicates inside the living cells of organisms. It is a small infectious agent that can replicate only inside the living cells of organisms. Most are too small to be seen by anything but a microscope and they infect all organisms from animals to plants to bacteria. The first one discovered was the tobacco virus in 1898. Since then around 5,000 viruses...

Venezuelan equine encephalitis

Venezuelan equine encephalitis virus is a mosquito-borne viral pathogen that causes Venezuelan equine encephalitis or encephalomyelitis (VEE). It can affect all equine species, such as horses, donkeys, and zebras. Equines may suddenly die or show progressive central nervous system disorders after infection. It is contractible by humans and will usually experience flu-like symptoms when...

The SARS coronavirus is the virus that causes severe acute respiratory syndrome (SARS). In 2003 the World Health Organization issued a press release stating that the coronavirus identified by a number of laboratories was the official cause of SARS. It causes severe illness marked initially by systemic symptoms of muscle pain, headache, fever, followed in 2-10 days by the onset of respiratory...

Rinderpest (also cattle plague) is an infectious viral disease of cattle, domestic buffalo, and some species of wildlife. It is characterized by fever, oral erosions, diarrhea, lymphoid necrosis, and high mortality. The last confirmed case was in 2001. In 2011 it should be announced that a global eradication of rinderpest was complete. The term comes from the German language meaning...

Respiratory syncytial virus (RSV) causes respiratory tract infections and is a major cause of lower respiratory tract infection and hospital visits during infancy and childhood. For premature infants and infants with congenital heart disease there is a prophylactic medication. During winter months in temperate climates there is an annual epidemic. Infection in tropical climates is most...

Rabies Virus
2011-02-23 17:45:51

The rabies virus is neurotropic virus, transmissible through the saliva of animals, that causes fatal disease in human and animals. Rabies is the type species of the Lyssavirus genus of Rhabdovirdae family. They are enveloped and single stranded RNA genome with negative-sense. All replication takes place in the cytoplasm. The virus has a bullet-like shape. Rabies enters the host cells through...

Phocine distemper virus (PDV) is a pathogenic for pinniped species such as seals. Signs include labored breathing, fever, and nervous symptoms. It was first identified in 1988 as the cause of death of 18,000 harbour seals along the northern European coast. A PDV epidemic occurred again in 2002 along the North Sea coast resulted in the deaths of 21,700 seals. Numerous carnivorous mammal species...

Cottontail Rabbit Papilloma Virus

The cottontail rabbit papilloma virus (CRPV), is a type I virus under the Baltimore scheme and posses a non-segmented dsDNA genome. It infects rabbits by causing keratinous carcinomas usually near the animal's head. These tumors eventually interfere with the host's ability to eat and can lead to starvation. The virus provided the first mammalian model of a cancer caused by a virus. The name...

Parapoxviruses, belonging to the Poxviridae family, are oval, relatively large, double-stranded DNA viruses. They have a unique spiral coat that distinguishes them from other poxviruses. Some of the viruses are zoonotic but not all. Zoonotic hosts include sheep, goats, and cattle. The New Zealand Red Deer is the most recent species to have been found with Parapoxvirus. The viruses tend to...

Influenza A Virus
2011-02-17 15:02:05

Influenza A virus causes influenza in birds and some mammals. It is a genus of the Orthomyxoviridae family of viruses. Although the virus is uncommon several strains have been isolated from wild birds. Some can cause severe disease in domestic poultry and sometimes in humans. They are negative sense, single-stranded, segmented RNA viruses. Each subtype has mutated into a variety of strains with...
