Mastadenovirus
''Mastadenovirus'' is a genus of viruses in the family ''Adenoviridae''. Humans and other mammals serve as natural hosts. There are 51 species in this genus. The genus as a whole includes many very common causes of human infection, estimated to be responsible for 2 to 5% of all respiratory infections, as well as gastrointestinal and eye infections. Symptoms are usually mild. Specific tropisms include: serotypes 3, 5, and 7: lower respiratory tract infections, serotypes 8, 19, and 37: epidemic keratoconjunctivitis, serotypes 4 and 7: acute respiratory disease, serotypes 40 and 41: gastroenteritis, serotype 14: can cause potentially fatal adenovirus infections. Canine mastadenovirus A (formerly canine adenovirus-1, CAdV-1) can lead to death in puppies, or encephalitis in other carnivore species. Etymology The name ''Mastadenovirus'' is derived from the Greek word ''mastos'' 'breast' (hence ''mammal'') and ''adenovirus'', named for the human adenoids, which the virus was first i ...

Bat Mastadenovirus A
''Bat mastadenovirus A'', formerly Bat adenovirus TJM, is a species of the genus '' Mastadenovirus'' of the family ''Adenoviridae''. It is a double stranded DNA virus with no RNA sequence. The designation TJM refers to the strain as there are several species of Bat adenoviruses in three groups 1, 2, and 3. Virology ''Bat mastadenovirus A'' is most closely related to '' Tree shrew mastadenovirus A'' and '' Canine mastadenovirus A''. Its genome consists of 30 putative genes exhibiting wide genetic diversity among bat species and within the same species harboring AdVs. Reservoir ''Bat mastadenovirus A'' was first isolated from ''Myotis'' and ''Scotophilus kuhlii'' bats in Beijing, Hunan, Jiangxi, Yunnan, Guizhou and Hainan provinces in China in 2007 and 2008. Transmission Transmission between same species is believed to be by droplet respiration and aerosolization of saliva, urine, and feces in closed environments such as caves and other bat roosts. Genomic analysis suggest ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Adenoviridae
Adenoviruses (members of the family ''Adenoviridae'') are medium-sized (90–100 nm), nonenveloped (without an outer lipid bilayer) viruses with an icosahedral nucleocapsid containing a double-stranded DNA genome. Their name derives from their initial isolation from human adenoids in 1953. They have a broad range of vertebrate hosts; in humans, more than 50 distinct adenoviral serotypes have been found to cause a wide range of illnesses, from mild respiratory infections in young children (known as the common cold) to life-threatening multi-organ disease in people with a weakened immune system. Virology Classification This family contains the following genera: * '' Atadenovirus'' * '' Aviadenovirus'' * '' Ichtadenovirus'' * '' Mastadenovirus'' (including all human adenoviruses) * '' Siadenovirus'' * '' Testadenovirus'' Diversity In humans, currently there are 88 human adenoviruses (HAdVs) in seven species (Human adenovirus A to G): * A: 12, 18, 31 * B: 3, 7, 11, 14, ...

Human Adenovirus 41
Human adenovirus 41 (HAdV-F41), is an enteric '' Adenovirus'', a nonenveloped virus with an icosahedral nucleocapsid containing a double-stranded DNA genome. It can particularly target the gastrointestinal tract to cause gastroenteritis, with symptoms similar to rotavirus gastroenteritis and norovirus. It may be present in the gut without causing symptoms and can be detected by using molecular based assays and enzyme immunoassay. As of August 2022, human adenovirus 41 has been identified in a majority of small children with hepatitis of unknown cause in 2 case series. Classification Human adenovirus 41 belongs to the ''Adenoviridae'' family, and along with human adenovirus 40, is a member of species human mastadenovirus F. Pathology It can particularly target the gastrointestinal tract to cause gastroenteritis in very young children. Symptoms appear similar to rotavirus gastroenteritis and norovirus. It may be present in the gut without causing symptoms. In an invest ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Canine Mastadenovirus A
Infectious canine hepatitis (ICH) is an acute liver infection in dogs caused by ''Canine mastadenovirus A'', formerly called ''Canine adenovirus 1'' (CAV-1). CAV-1 also causes disease in wolves, coyotes, and bears, and encephalitis in foxes. The virus is spread in the feces, urine, blood, saliva, and nasal discharge of infected dogs. It is contracted through the mouth or nose, where it replicates in the tonsils. The virus then infects the liver and kidneys. The incubation period is 4 to 9 days. Symptoms include fever, depression, loss of appetite, coughing, and a tender abdomen. Corneal edema and signs of liver disease, such as jaundice, vomiting, and hepatic encephalopathy, may also occur. Severe cases will develop bleeding disorders, which can cause hematomas to form in the mouth. Death can occur secondary to this or the liver disease. However, most dogs recover after a brief illness, although chronic corneal edema and kidney lesions may persist. Diagnosis is made by re ...
