The Eta variant or lineage B.1.525, also called VUI-21FEB-03 [30] (previously VUI-202102/03) by Public Health England (PHE) and formerly known as UK1188, [30] 21D [75] or 20A/S:484K, [98] does not carry the same N501Y mutation found in Alpha, Beta and Gamma, but carries the same E484K-mutation as found in the Gamma, Zeta, and Beta variants, and ...
“Variants that can infect people better or evade immunity to the last variant are more likely to cause a new COVID wave,” Peter Kasson, M.D., Ph.D., B.S., of the University of Virginia’s ...
Duitsland (common, Dutch), Allemagne (common, French), Alemania (common, Spanish), Germania (common, Italian, Latin name), Německo (common, Czech), Niemcy (common, Polish), Németország (common, Hungarian) [the common name for Germany in some Romance languages is a variant of the place name Alemannia and in many Slavic languages is a variant ...
In microbiology and virology, the term variant or genetic variant is used to describe a subtype of a microorganism that is genetically distinct from a main strain, but not sufficiently different to be termed a distinct strain. A similar distinction is made in botany between different cultivated varieties of a species of plant, termed cultivars.
Omicron (BA.1, EG.5, BA.2.86) Omicron was the predominant variant circulating in the U.S. between late 2021 and 2023. It was first identified in late 2021 in Botswana and South Africa and quickly ...
It has been said that "there is no universally accepted definition for the terms 'strain', 'variant', and 'isolate' in the virology community, and most virologists simply copy the usage of terms from others". [2] A strain is a genetic variant or subtype of a microorganism (e.g., a virus, bacterium or fungus).
The approach for Covid-19 jabs will be similar to that used for the modified flu vaccine to deal with new strains each year, the regulator said.
The word "allele" is a short form of "allelomorph" ("other form", a word coined by British geneticists William Bateson and Edith Rebecca Saunders) in the 1900s, [7] [8] which was used in the early days of genetics to describe variant forms of a gene detected in different phenotypes and identified to cause the differences between them.
