The rinderpest virus (RPV) is a RNA virus of the family Paramyxoviridae (genus Morbillivirus ). The virus causes rinderpest and can affect all ruminants and other ungulates such as hippos . It was declared eradicated in 2010 after a coordinated worldwide vaccination and culling campaign and is therefore only the second pathogen after the smallpox virus ( Orthopoxvirus variola alias Variola virus ) that has been successfully eradicated.

Discovery and Characterization

In 1902, the French researcher Maurice Nicolle and his Ottoman-Turkish colleague Mustafa Adil showed that the causative agent of rinderpest was a filterable agent, ie not a bacterium. Simmons determined the size of the virus particles ( virions ) in 1940 to be 860 to 1260  Å . The first complete sequence of a virus genome was published in 1996.

features

The virus particles of the RPV are round to irregularly oval with a diameter of 150 to 250 nm and have a lipid envelope . The genome is 15,991 bases in length and consists of a single RNA - molecule . This RNA contains the six genes N, P, L, H, F and M, which code for structural proteins . One of the genes, the P gene, also codes for two non-structural proteins.

The rinderpest virus is closely related to the measles virus , the causative agent of the plague of small ruminants ( Peste des petits ruminants virus , PPRV) and the distemper virus (same genus). According to current scientific opinion, the measles virus developed from the rinderpest virus . The point in time of this transition cannot be determined with certainty. While earlier works assumed that this happened thousands of years ago, more recent works date this event to the 11th to 12th centuries AD. All other morbilliviruses may also be derived from the rinderpest virus .

Different virus strains can differ greatly in terms of virulence and species-specific susceptibility.
