Negative-strand RNA viruses (−ssRNA viruses) are a group of related viruses that have negative-sense, single-stranded genomes made of ribonucleic acid (RNA). They have genomes that act as complementary strands from which messenger RNA (mRNA) is synthesized by the viral enzyme RNA-dependent RNA polymerase (RdRp). During replication of the ...
Mononegavirales is an order of negative-strand RNA viruses which have nonsegmented genomes. Some members that cause human disease in this order include Ebola virus, human respiratory syncytial virus, measles virus, mumps virus, Nipah virus, and rabies virus. Important pathogens of nonhuman animals and plants are also in the group.
Positive-strand RNA viruses can also be classified based on the RNA-dependent RNA polymerase. Three groups have been recognised: [ 25 ] Bymoviruses, comoviruses, nepoviruses, nodaviruses, picornaviruses, potyviruses, sobemoviruses and a subset of luteoviruses (beet western yellows virus and potato leafroll virus)—the picorna like group ...
Baltimore classification groups viruses together based on their manner of mRNA synthesis. Characteristics directly related to this include whether the genome is made of deoxyribonucleic acid (DNA) or ribonucleic acid (RNA), the strandedness of the genome, which can be either single- or double-stranded, and the sense of a single-stranded genome, which is either positive or negative.
Riboviria contains three types of viruses that replicate via RdRp: single-stranded RNA (ssRNA) viruses, which are either positive (+) or negative (-) sense, and double-stranded RNA viruses (dsRNA), all of which belong to the kingdom Orthornavirae. +ssRNA viruses have genomes that can functionally act as mRNA, and a negative-sense strand can ...
Pneumoviridae (from Greek pneumo-'lung' + -viridae 'virus', from Latin, 'poison, slimy liquid') [2] is a family of negative-strand RNA viruses in the order Mononegavirales. [1] [3] Humans, cattle, and rodents serve as natural hosts. [4] Respiratory tract infections are associated with member viruses such as human respiratory syncytial virus.
Bunyavirales is an order of segmented negative-strand RNA viruses with mainly tripartite genomes. Member viruses infect arthropods, plants, protozoans, and vertebrates. [2] It is the only order in the class Ellioviricetes. [1] The name Bunyavirales derives from Bunyamwera, [3] where the original type species Bunyamwera orthobunyavirus was first ...
Paramyxoviridae (from Greek para-“by the side of” and myxa “mucus”) is a family of negative-strand RNA viruses in the order Mononegavirales. [1] [2] Vertebrates serve as natural hosts. [3] Diseases associated with this family include measles, mumps, and respiratory tract infections. [4]
