A virus genus is a group of related species that share some significant properties and often only differ in host range and virulence. A genus name must be a single word ending in the suffix -virus. Approval of a new genus must be accompanied by the approval of a type species. [10]: §3.24
Virus classification is the process of naming viruses and placing them into a taxonomic system similar to the classification systems used for cellular organisms. Viruses are classified by phenotypic characteristics, such as morphology, nucleic acid type, mode of replication, host organisms, and the type of disease they cause.
Infectious bronchitis virus (IBV), a type of coronavirus, causes avian infectious bronchitis. [131] The virus is of concern to the poultry industry because of the high mortality from infection, its rapid spread, and its effect on production. [127] The virus affects both meat production and egg production and causes substantial economic loss. [132]
Coronavirus diseases are caused by viruses in the coronavirus subfamily, a group of related RNA viruses that cause diseases in mammals and birds. In humans and birds, the group of viruses cause respiratory tract infections that can range from mild to lethal.
Coronaviridae is a family of enveloped, positive-strand RNA viruses which infect amphibians, birds, and mammals.Commonly referred to as coronaviruses in the English language, the family coronaviridae includes the subfamilies Letovirinae and Orthocoronavirinae; the latter also known as coronavirinae.
A viral disease (or viral infection) occurs when an organism's body is invaded by pathogenic viruses, and infectious virus particles (virions) attach to and enter susceptible cells. [1] Examples include the common cold, gastroenteritis, COVID-19, the flu, and rabies. [2]
“Well-meaning, uninformed aquarium owners sometimes release their pets thinking they’re doing the best thing for them, but if they do survive, they can become invasive and harm the native ...
This article aims at keeping an up-to-date list of Coronavirus strains and subspecies successfully isolated and cultured in laboratory, a task which is often challenging. When relevant it shall include a few synthetic chimera as well as some strains that were only propagated in laboratory animals.
