| bunyamwera group viruses |
A large group of viruses from many parts of the world assigned to the bunyavirus genus of the family bunyaviridae. They are transmitted by mosquitoes and infect humans in some areas. This group contains the type species of the genus, bunyamwera virus.

| california group viruses |
A group of viruses in the bunyavirus genus of the bunyaviridae family. They are found in temperate and arctic regions and each is closely associated with a single species of vector mosquito. The vertebrate hosts are usually small mammals but several virus species infect humans.

| parainfluenza viruses |
Virus's of the genus Paramyxovirus, of four types: type 1 (haemadsorption virus type 2), which includes sendai virus, causes acute laryngotracheitis in children and occasionally adults; type 2 (croup-associated virus) is associated especially with acute laryngotracheitis or croup in young children and minor upper respiratory infections in adults; type 3 (haemadsorption virus type 1; shipping fever virus) has been isolated from small children with pharyngitis, bronchiolitis, and pneumonia, and causes occasional respiratory infection in adults; bovine strains have been isolated from cattle with shipping fever, and the virus has also been isolated from sheep; type 4 has been isolated from a very few children with minor respiratory illness.

| viruses |
<microbiology, virology> An ultra-microscopic micro-organism, parasitic within living cells and of which many can cause disease in humans. They consist of a strand of nucleic acid (DNA or RNA) that contains genetic instructions concerning viral reproduction that is enveloped by a protein coat. Cellular rupture (and death) liberates the newly from viruses.
