This 1975 transmission electron micrograph (TEM) revealed the presence of a number of infectious bronchitis virus (IBV) virions, which are Coronaviridae family members, and members of the genus Coronavirus. IBV is a highly contagious pathogen, which infects poultry of all ages, affecting a number of organ systems including the respiratory and urogenital organs. IBV is categorized as a Group 3 coronavirus member, with a helical genome composed of positive-sense single-stranded RNA ((+) ssRNA). This is an enveloped virus, which means that its outermost covering is derived from the host cell membrane.Created: 1975
This negatively-stained 1975 transmission electron micrograph (TEM) revealed the presence of a number of human cooronavirus, HCoV-229E virions. This organism is a member of the family, Coronaviridae, and the genus Coronavirus. The coronavirus helical genome is composed of positive-sense single-stranded RNA ((+) ssRNA). This is an enveloped virus, which means that its outermost covering is derived from the host cell membrane.Created: 1975
This negatively-stained transmission electron micrograph (TEM) revealed the presence of numerous coronavirus virions in this tissue sample. Coronavirus is a member of the virus family, Coronaviridae, which at their core contain a positive-sense single-stranded RNA genome ((+) ssRNA). Under electronmicrographic examination, the envelope surrounding each virion is studded with a corona of points, hence the derivation of its name, which are actually proteinaceous in nature, and are outcroppings of its envelope's molecular structure.Coronaviruses infect mammals and birds with upper respiratory and gastrointestinal illnesses. The most well-known member of this virus family is the human coronavirus responsible for causing severe acute respiratory syndrome (SARS).Created: 1975

Description: English: (left) Schematic diagrams of coronavirus virions; (right top) The topology of the four structural envelope proteins. All proteins are depicted as monomers, but the S and HE proteins form homotrimers and homodimers, respectively. Oligosaccharides are shown on the M, S, and HE proteins. Although a number are omitted, the S and HE proteins contain 21 to 35 and 9 (BCoV HE) potential N-glycosylation sites, respectively; (right bottom) Electron micrograph of SCoV. Bar: 100 nm.

Description: English: Genome organizations of various Coronavirus genera. The first two-thirds of the genome contains open reading frame (ORF)1a and ORF1b, which encode the replicase/transcriptase proteins (Green). The remaining one-third of the genome encodes four structural proteins: spike (S), envelope (E), membrane (M), and nucleocapsid (N) proteins (Orange). Some betaoronaviruses have an additional hemagglutinin-esterase (HE) gene (Orange). The genome of each genus or species has a set of unique accessory proteins (red). Date: 3 April 2015.
