Viral replication is cytoplasmic. Entry into the host cell is achieved by virus attaching to host cell. Replication follows the negative-stranded RNA virus replication model. Negative-stranded RNA virus transcription, using polymerase stuttering, through co-transcriptional RNA editing is the method of transcription. Translation takes place by ...
Negative-contrast electron micrographs of virions of Pyrobaculum spherical virus (PSV, genus Alphaglobulovirus). (Left) Intact virions; arrows indicate spherical protrusions. (Right) Partially disrupted virions extruding disordered nucleoprotein core. The bars represent 100 nm. Modified from (Häring et al., 2004; provided by ICTV).
Influenza A virus and influenza B virus co-circulate, so have the same patterns of transmission. [1] The seasonality of influenza C virus, however, is poorly understood. Influenza C virus infection is most common in children under the age of two, and by adulthood most people have been exposed to it.
Sindbis virus may have originated in South America. [13] The equine encephalitis viruses and the Sindbis virus are related. The Old World and New World viruses appears to have diverged between 2000 and 3000 years ago. [14] Divergence between the Venezuelan equine encephalitis virus and the eastern equine virus appears to have been ~1400 years ...
Influenza A virus structure. The influenzavirus virion is pleomorphic; the viral envelope can occur in spherical and filamentous forms. In general, the virus's morphology is ellipsoidal with particles 100–120 nm in diameter, or filamentous with particles 80–100 nm in diameter and up to 20 μm long. [5]
Virus crystallisation is the re-arrangement of viral components into solid crystal particles. [1] The crystals are composed of thousands of inactive forms of a particular virus arranged in the shape of a prism. [2] The inactive nature of virus crystals provide advantages for immunologists to effectively analyze the structure and function behind ...
Coronaviridae is a family of enveloped, positive-strand RNA viruses which infect fish, 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.
