Rhabdoviridae
Rhabdoviridae is a family of negative-strand RNA viruses in the order Mononegavirales. Vertebrates (including mammals), invertebrates, plants, fungi and protozoans serve as natural hosts. Diseases associated with member viruses include rabies encephalitis caused by the rabies virus, and flu-like symptoms in humans caused by vesiculoviruses. The name is derived from Ancient Greek , meaning rod, referring to the shape of the viral particles. The family has 64 genera, most assigned to four subfamilies.

Als Rhabdoviren (griech.: rhabdos – Stab) bezeichnet man die Viren der Familie der Rhabdoviridae. Vertreter dieser Familie haben Wirbeltiere, Insekten oder Pflanzen als Wirt. All diese Viren sind behüllte Einzel(-)-Strang-RNA-Viren = ss(-)RNA, meist stäbchenförmig, zylindrischer Gestalt.

Die Härchen dienen dem Virus, um in die Zellen einzudringen, was vermutlich durch Endocytose geschieht. Der Kern von Rhabdoviren besteht aus einem RNA-Einzelstrang negativer Polarität, d. h. er ist komplementär zur mRNA. Rhabdoviren sind umhüllt und haben helikale Nukleokapside, und ihre Genome sind linear, etwa 11–15 kb lang.[4] Rhabdoviren besitzen typischerweise Gene für fünf Proteine: ein großes Protein (L), Glykoprotein (G), Nukleoprotein (N), Phosphoprotein (P) und Matrixprotein (M).[5][6] Die Sequenz dieser Prot

== Structure == The individual virus particles (virions) of rhabdoviruses are composed of RNA, protein, carbohydrate and lipids. They have complex bacilliform or bullet-like shapes. All these viruses have structural similarities and have been classified as a single family.
