PB2 polymerase subunit of Thogoto virus (Orthomyxoviridae family)
Thogoto virus (THOV) represents a new genus in the family Orthomyxoviridae. The three polymerase subunits PB1, PB2, and PA initiate transcription by a unique cap-stealing mechanism that involves the cleavage of only the m(7)GpppAm structure from cellular hnRNAs. Here, we report the cloning of the longest genomic segment of THOV coding for PB2.

[Taxonomic structure of Orthomyxoviridae: current views and immediate prospects].
Analysis of taxonomic structure of Orthomyxoviridae was undertaken in view of its anticipated evolution. Four concepts of circulation of influenza A viruses in the biosphere are discussed, viz. anthrponose, zooanthroponose, metastrongilose, and protozoan. All of them may be considered in the framework of the general zooantroponose concept.

The representatives of this family of viruses are the three serologically unrelated types of influenza viruses A, B, and C, which are widely distributed in humans, other mammals and birds (Melnick, 1980). Type A is responsible for influenza pandemics and the regular epidemics. Type B has been found only in man so far and causes more localized epidemics.

Publisher Summary This chapter provides an overview of Orthomyxoviridae (Genus: Influenza Virus A, influenza virus B, and influenza virus C). In general, the influenza viruses are spherical, enveloped particles with two types of surface glycoprotein spikes and with a genome in the form of eight segments of single-stranded RNA.
