The Flaviviridae represent a family of viruses containing all of single-stranded RNA and are therefore assigned taxonomically to RNA viruses. The type species of the whole family is the yellow fever virus ( hence the name of the family of Latin flavus, "yellow" ).
All members of this family have a viral envelope lipids from the original host cell and viral proteins embedded in it and have a size of 40-60 nm, the viruses multiply in the cytoplasm of the host cell and are stable in the pH range of 7-9.
The pathogens of the genus Flavivirus call both in humans and in animals a large number of viral infections forth. Among these are the yellow fever, dengue fever, tick-borne encephalitis ( TBE ), West Nile fever, the Louping Ill, the Wesselsbron disease (sheep, goats and similar), and Japanese B encephalitis (birds and pigs).
So far, the only representative of Hepaciviren is the hepatitis C virus that causes the disease hepatitis C in humans.
The viruses of the genus Pestivirus play exclusively in animals as pathogens a role. This includes, inter alia, the SP- virus as a trigger of classical swine fever, the BVD / MD virus ( BVD Bovine Viral Diarrhoea ) and border disease of sheep.
