Asama orthohantavirus

Asama orthohantavirus(ASAV), also called Asama virus, is a single-stranded, enveloped, segmented negative-sense RNA hantavirus. [1] The hantavirus was isolated in Japan from Japanese shrew mole. [1] Hantaviruses harbored by shrews are genetically closer to ASAV than to hantaviruses harbored by rodents. [1] Host-switching may be evident in the future due to the viruses closeness to soricine shrew-borne hantaviruses. [1] The detection of the ASAV was the first hantavirus found to be hosted by members of the family Talpidae , which includes shrew moles. [2] Thoughts on hantavirus evolutionary history has expanded due to the discovery of ASAV. [1]

Natural reservoir

Asama virus was isolated through RNA extracts from lung tissues of the Japanese shrew mole ( Urotrichus talpoides ), captured in Japan between February and April 2008. It is one of the first hantaviruses found in a mole.[ citation needed ]

Virology

Asama virus is genetically closer to other hantaviruses harbored by shrews than by rodents. However, the nucleocapsid protein is similar to that of rodent and shrew-borne hantaviruses. Phylogenetic analyses positions it closest to soricine shrew-borne hantaviruses. This suggests a possible host-switching event in the distant past.[ citation needed ]

Asama virus is related to soricine shrew-borne hantaviruses that are found in North America, Europe, and Asia. This relation was discovered through phylogenetic analyses. The relationship between the two hantaviruses may suggest parallel evolution associated with cross-species transmission. [3]

<i>Orthohantavirus</i> Genus of viruses

Orthohantavirus is a genus of single-stranded, enveloped, negative-sense RNA viruses in the family Hantaviridae within the order Bunyavirales. Members of this genus may be called orthohantaviruses or simply hantaviruses.

<i>Bunyavirales</i> Order of negative-sense single-stranded RNA viruses

Bunyavirales is an order of segmented negative-strand RNA viruses with mainly tripartite genomes. Member viruses infect arthropods, plants, protozoans, and vertebrates. It is the only order in the class Ellioviricetes. The name Bunyavirales derives from Bunyamwera, where the original type species Bunyamwera orthobunyavirus was first discovered. Ellioviricetes is named in honor of late virologist Richard M. Elliott for his early work on bunyaviruses.

Seoul orthohantavirus (SEOV) is a member of the Orthohantavirus family of rodent-borne viruses and is one of the 4 hantaviruses that are known to be able to cause Hantavirus hemorrhagic fever with renal syndrome (HFRS). It is an Old World hantavirus; a negative sense, single-stranded, tri-segmented RNA virus.

<i>Andes orthohantavirus</i> Species of virus

Andes orthohantavirus (ANDV), a species of Orthohantavirus, is a major causative agent of hantavirus cardiopulmonary syndrome (HCPS) and hantavirus pulmonary syndrome (HPS) in South America. It is named for the Andes mountains of Chile and Argentina, where it was first discovered. Originating in the reservoir of rodents, Andes orthohantavirus is easily transmitted to humans who come into contact with infected rodents or their fecal droppings. However, infected rodents do not appear ill, so there is no readily apparent indicator to determine whether the rodent is infected or not. Additionally, Andes orthohantavirus, specifically, is the only hantavirus that can be spread by human to human contact via bodily fluids or long-term contact from one infected individual to a healthy person.

<span class="mw-page-title-main">Urotrichini</span> Tribe of mammals

Urotrichini is a tribe of the mole family, and consists of Japanese and American shrew-moles. They belong to the Old World moles and relatives branch of the mole family (Talpidae). There are only two species, each of which represents its own genus. The name "shrew-moles" refers to their morphological resemblance to shrews, while generally being thought of as "true moles". The species are the Japanese shrew mole, True's shrew mole and American shrew mole.
