The name alphacoronavirus is derived from Ancient Greek ἄλφα (álpha, "the first letter of the Greek alphabet"), and κορώνη (korṓnē, "garland, wreath"), meaning crown, which describes the appearance of the surface projections seen under electron microscopy that resemble a solar corona.
The morphology of the SARS-related coronavirus is characteristic of the coronavirus family as a whole. The viruses are large pleomorphic spherical particles with bulbous surface projections that form a corona around the particles in electron micrographs. [50] The size of the virus particles is in the 80–90 nm range.
The human coronavirus NL63 shared a common ancestor with a bat coronavirus (ARCoV.2) between 1190 and 1449 CE. [76] The human coronavirus 229E shared a common ancestor with a bat coronavirus (GhanaGrp1 Bt CoV) between 1686 and 1800 CE. [77] More recently, alpaca coronavirus and human coronavirus 229E diverged sometime before 1960. [78]
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.
HCoV-229E is associated with a range of respiratory symptoms, ranging from the common cold to high-morbidity outcomes such as pneumonia and bronchiolitis.However, such high morbidity outcomes are almost always seen in cases with co-infection with other respiratory pathogens; there is a single published case report to date of a 229E infection that caused acute respiratory distress syndrome ...
Cholera (caused by Vibrio cholerae bacteria) and bubonic plague, or the Black Death (caused by the bacterium Yersinia pestis) are some of the most famous examples of how devastating a pandemic can be.
Dozens of captive animal species have been found infected or proven able to be experimentally infected with SARS-CoV-2, the virus that causes COVID-19. The virus has also been found in over a dozen wild animal species. Most animal species that can get the virus have not been proven to be able to spread it back to humans.
Microbial cultures on solid and liquid media. A microbiological culture, or microbial culture, is a method of multiplying microbial organisms by letting them reproduce in predetermined culture medium under controlled laboratory conditions. Microbial cultures are foundational and basic diagnostic methods used as research tools in molecular biology.
