Togaviridae Wikipedia. Togaviridae is a family of viruses. Humans, mammals, birds, and mosquitoes serve as natural hosts. There are currently 3. Diseases associated with this family include Alphaviruses arthritis, encephalitis Rubiviruses rubella. TaxonomyeditGroup ss. RNA2StructureeditThe Togaviridaefamily belong to group IV of the Baltimore classification of viruses. TLk8ki8.jpg' alt='Family Reunion Vector Free Download' title='Family Reunion Vector Free Download' />The genome is linear, non segmented, single stranded, positive sense RNA that is 1. The 5 terminus carries a methylatednucleotide cap and the 3 terminus has a polyadenylated tail, therefore resembling cellular m. RNA. The virus is enveloped and forms spherical particles 6. Genus.

Life cycleeditEntry into the host cell is achieved by attachment of the viral E glycoprotein to host receptors, which mediates clathrin mediated endocytosis. The receptors for binding are unknown, however the tropism is varied and it is known that the glycoprotein petal like spikes act as attachment proteins. After virus attachment and entry into the cell, gene expression and replication takes place within the cytoplasm. Replication follows the positive stranded RNA virus replication model.

Positive stranded RNA virus transcription is the method of transcription. Translation takes place by viral initiation, and suppression of termination. The vector for Togaviridae is primarily the mosquito, where replication of the virus occurs. The Togaviridae family is classified into Old World and New World viruses based on geographical distribution, although its likely that a few transoceanic crossings have occurred. Human, mammals, marsupials, birds, and mosquitoes serve as the natural host. Ost Pst Converter Full Version. Transmission routes are zoonosis, bite, and respiratory. Genus. Host details.

ReplicationeditThe non structural proteins are encoded at the 5 end, formed during the first of two characteristic rounds of translation. These proteins are originally translated as a polyprotein, which consequently undergo self cleavage, forming four non structural proteins responsible for gene expression and replication. The formation of a sub genomic fragment, encoding the structural proteins and a negative sense fragment, a template for further synthesis of positive sense RNA are the characteristic second phase of translation. Assembly takes place at the cell surface, where the virus buds from the cell, acquiring the envelope. The replication cycle is very fast, taking around 4 hours. HistoryeditInitially the Togavirus family included what are now called the Flaviviruses, within the Alphavirus genus. The Flaviviruses were formed into their own family when sufficient differences with the Alphaviruses were noted thanks to the development of sequencing. The last major epidemic of Rubella in the United States is seen. Approximately 2. 0,0. Rubella vaccine is licensed. Last epidemic of Venezuelan equine encephalitis is seen in horses in southern Texas. Major epidemic of the chikungunya virus in India with over 1. Referencesedit abcdViral Zone. Ex. PASy.
