An isolate of a particular organism, thought to be different from other known organisms of that species.
An organism that is different from other organisms of the same species due to genetic differences. Strain is commonly used in two ways: (i) organisms of the same species that when initially isolated are found to have certain different properties (due to unknown mutations) are called different strains; (ii) derivatives of an organism that have distinct genotypes due to known mutations are called different strains.
Different organism within same species.
A selection of a variety, cultivar or species which is raised from seed.
A type within a variety that constantly differs in genetic factors from other strains of the same variety, may become a variety.
In guppies, a line developed which differentiates from the original species with its own genetic pattern, colour and other tendencies; ex. Purple Delta.
A subgroup or subtype of a species having one or more characteristics that distinguish it from other subgroups of that species.
varieties or species that are only propagated through seed.
A variety of a given species. Some species, particularly livebearers, have huge numbers of strains, usually separated by colour.
a special variety of domesticated animals within a species; "he experimented on a particular breed of white rats"; "he created a new strain of sheep"
(biology) a group of organisms within a species that differ in trivial ways from similar groups; "a new strain of microorganisms"
a different genetic version of the same species of bacteria
a line of individuals of a certain species
a subset of a bacterial species differing from other bacteria of the same species by some minor but identifiable difference
a group of organisms within a species that differ in trivial ways from similar groups, as in a new strain of flu virus.
A word used to label some pathogens (including insect pathogens) according to their geographical origin. For example, in the last few years a Hong Kong strain and a Beijing strain of human influenza have been labelled. Strains of the insect pathogen Beauveria bassiana likewise have been labeled. Strain does not mean the same things as species.
A group of organisms within a species or type that share a common quality. For example, currently circulating strains of influenza.
A variety of a certain species. The freshwater guppy, for example, has only one species name but several strains.
A group of organisms within a species or variety.
A group of organisms within a species that can be characterized by some particular quality.
An organism that is geneticaly different from others of the same species. Also known as a cultivar.
isolate of a bacterial species which is differentiated from other isolates of the same species by particular characteristics.
a population of bacteria within a species or sub-species identified by typing ( q.v.)
( Genet.). A term loosely used as a synonym for race ( Deprec.). More strictly, a group within a variety that constantly differs in one or more genetic factors from the variety proper. ( BCFT).
A variety of organism defined by the genes it contains. A population of an organism may consist of several different strains.
Aquarium developed variant of a species. Same as variety.
Subgroup of a species (also called taxon).
A genetic variant within a species.
A group of organisms of the same species, having distinctive characteristics, but not usually considered a separate breed or variety.
a subgroup of a species; the descendants of a common ancestor.
Subgroup of a species. For HIV, different types of HIV such as HIV-1, HIV-2, clade A, clade B, etc.
The equivalent of race in plants and animals. The same Species may consist of strains that vary considerably in genetic make up, but all are sexually compatible
A sub-species group of organisms distinguishable from the rest of the species by a heritable characteristic that the individuals in the group have in common. ()
