Horseshoe bats are bats in the family Rhinolophidae. In addition to the single living genus, Rhinolophus, which has about 106 species, the extinct genus Palaeonycteris has been recognized. Horseshoe bats are closely related to the Old World leaf-nosed bats, family Hipposideridae, which have sometimes been included in Rhinolophidae. The horseshoe bats are divided into six subgenera and many species groups. The most recent common ancestor of all horseshoe bats lived 34–40 million years ago, though it is unclear where the geographic roots of the family are, and attempts to determine its biogeography have been indecisive. Their taxonomy is complex, as genetic evidence shows the likely existence of many cryptic species, as well as species recognized as distinct that may have little genetic divergence from previously recognized taxa. They are found in the Old World, mostly in tropical or subtropical areas, including Africa, Asia, Europe, and Oceania.
Lyssavirus is a genus of RNA viruses in the family Rhabdoviridae, order Mononegavirales. Mammals, including humans, can serve as natural hosts. The genus Lyssavirus includes the rabies virus traditionally associated with the disease of the same name.
Rabies virus, scientific name Rabies lyssavirus, is a neurotropic virus that causes rabies in humans and animals. Rabies transmission can occur through the saliva of animals and less commonly through contact with human saliva. Rabies lyssavirus, like many rhabdoviruses, has an extremely wide host range. In the wild it has been found infecting many mammalian species, while in the laboratory it has been found that birds can be infected, as well as cell cultures from mammals, birds, reptiles and insects. Rabies is reported in more than 150 countries on all continents, with the exclusion of Antarctica. The main burden of disease is reported in Asia and Africa, but some cases have been reported also in Europe in the past 10 years, especially in returning travellers.
Australian bat lyssavirus (ABLV), originally named Pteropid lyssavirus (PLV), is a zoonotic virus closely related to the rabies virus. It was first identified in a 5-month-old juvenile black flying fox collected near Ballina in northern New South Wales, Australia, in January 1995 during a national surveillance program for the recently identified Hendra virus. ABLV is the seventh member of the genus Lyssavirus and the only Lyssavirus member present in Australia.
Mokola lyssavirus, commonly called Mokola virus (MOKV), is a RNA virus related to rabies virus that has been sporadically isolated from mammals across sub-Saharan Africa. The majority of isolates have come from domestic cats exhibiting symptoms characteristically associated to rabies virus infection.
Lagos bat lyssavirus, formerly Lagos bat virus (LBV) is a Lyssavirus of southern and central Africa that causes a rabies-like illness in mammals. It was first isolated from a fruit bat from Lagos Island, Nigeria in 1956. Brain samples from the bat showed poor cross-reactivity to rabies antibodies but the virus was found to be closely related to the rabies virus. This was the first discovery of a rabies-related virus. Until this time, rabies was thought to have a single causal agent.
Human coronavirus NL63 (HCoV-NL63) is a species of coronavirus, specifically a Setracovirus from among the Alphacoronavirus genus. It was identified in late 2004 in a seven-month-old child with bronchiolitis in the Netherlands. The virus is an enveloped, positive-sense, single-stranded RNA virus which enters its host cell by binding to ACE2. Infection with the virus has been confirmed worldwide, and has an association with many common symptoms and diseases. Associated diseases include mild to moderate upper respiratory tract infections, severe lower respiratory tract infection, croup and bronchiolitis.
Duvenhage lyssavirus (DUVV) is a member of the genus Lyssavirus, which also contains the rabies virus. The virus was discovered in 1970, when a South African farmer died of a rabies-like encephalitic illness, after being bitten by a bat. In 2006, Duvenhage virus killed a second person, when a man was scratched by a bat in North West Province, South Africa, 80 km from the 1970 infection. He developed a rabies-like illness 27 days after the bat encounter, and died 14 days after the onset of illness. A 34-year-old woman who died in Amsterdam on December 8, 2007, was the third recorded fatality. She had been scratched on the nose by a small bat while travelling through Kenya in October 2007, and was admitted to hospital four weeks later with rabies-like symptoms.
Hipposideros is one of the most diverse genera of bats, with more than 70 species. They are collectively called roundleaf bats after the shape of their nasal ornament. It is the type genus of the family Hipposideridae. It is divided into species groups based on morphology.
The African long-fingered bat is a species of vesper bat in the family Vespertilionidae. It is found only in Kenya. It is found in subtropical or tropical moist montane forests. This species is often considered a synonym of Miniopterus inflatus. The holotype was collected in October 1926 by A. M. Bailey. It was described as a new species in 1936 by Colin Campbell Sanborn.
The São Tomé leaf-nosed bat is a species of bat in the family Hipposideridae. It is endemic to the island of São Tomé, in the Gulf of Guinea off the western coast of Africa. The bat's natural habitats are subtropical or tropical moist lowland forests and caves.
The Hipposideridae are a family of bats commonly known as the Old World leaf-nosed bats. While it has often been seen as a subfamily, Hipposiderinae, of the family Rhinolophidae, it is now more generally classified as its own family. Nevertheless, it is most closely related to Rhinolophidae within the suborder Yinpterochiroptera.
Rabies is a viral disease that causes inflammation of the brain in humans and other mammals. Early symptoms can include fever and tingling at the site of exposure. These symptoms are followed by one or more of the following symptoms: nausea, vomiting, violent movements, uncontrolled excitement, fear of water, an inability to move parts of the body, confusion, and loss of consciousness. Once symptoms appear, the result is virtually always death. The time period between contracting the disease and the start of symptoms is usually one to three months but can vary from less than one week to more than one year. The time depends on the distance the virus must travel along peripheral nerves to reach the central nervous system.
The cave nectar bat, dawn bat, common dawn bat, common nectar bat or lesser dawn bat is a species of megabat within the genus Eonycteris. The scientific name of the species was first published by Dobson in 1871.
The striped leaf-nosed bat is a species of bat native to eastern and southern Africa. It was formerly considered part of M. commersoni, which is now viewed as being restricted to Madagascar. Both commersoni and it were formerly placed in the genus Hipposideros, but moved to the resurrected Macronycteris in 2017 on the basis of molecular evidence.
Cryptic rabies refers to infection from unrecognized exposure to rabies virus. It is often phylogenetically traced to bats. It is most often seen in the southern United States. Silver-haired bats and tricolored bats are the two most common bat species associated with this form of infection, though both species are known to have less contact with humans than other bat species such as the big brown bat. That species is common throughout the United States and often roosts in buildings and homes where human contact is more likely.
The bat virome is the group of viruses associated with bats. Bats host a diverse array of viruses, including all seven types described by the Baltimore classification system: (I) double-stranded DNA viruses; (II) single-stranded DNA viruses; (III) double-stranded RNA viruses; (IV) positive-sense single-stranded RNA viruses; (V) negative-sense single-stranded RNA viruses; (VI) positive-sense single-stranded RNA viruses that replicate through a DNA intermediate; and (VII) double-stranded DNA viruses that replicate through a single-stranded RNA intermediate. The greatest share of bat-associated viruses identified as of 2020 are of type IV, in the family Coronaviridae.
European bat 1 lyssavirus(EBLV-1) is one of three rabies virus-like agents of the genus Lyssavirus found in serotine bats in Spain. Strains of EBLV-1 have been identified as EBLV-1a and EBLV-1b. EBLV-1a was isolated from bats found in the Netherlands and Russia, while EBLV-1b was found in bats in France, the Netherlands and Iberia. E. isabellinus bats are the EBLV-1b reservoir in the Iberian Peninsula. Between 1977 and 2010, 959 bat rabies cases of EBLV-1 were reported to the World Health Organization (WHO) Rabies Bulletin.
Commerson's roundleaf bat, also known as Commerson's leaf-nosed bat, is a species of bat endemic to Madagascar. It is named after French naturalist Philibert Commerson (1727-1773). Bat populations of Africa or São Tomé and Príncipe formerly considered part of this species are now classified separately as M. gigas, M. thomensis or M. vattatus, while one from Madagascar was split off to become M. cryptovalorona. It was formerly placed in the genus Hipposideros, but moved to the resurrected Macronycteris in 2017 on the basis of molecular evidence.
West Caucasian bat lyssavirus (WCBL) is a member of genus Lyssavirus, family Rhabdoviridae and order Mononegavirales. This virus was first isolated from Miniopterus schreibersii, in the western Caucasus Mountains of southeastern Europe in 2002. WCBL is the most divergent form of Lyssavirus, and is found in Miniopterus bats (insectivorous), Rousettus aegyptiacus, and Eidolon helvum. The latter two are both fruit bats. The virus is fragile as it can be inactivated by UV light and chemicals, such as ether, chloroform, and bleach. WCBL has not been known to infect humans thus far.
