Sensu is a Latin word meaning "in the sense of". It is used in a number of fields including biology, geology, linguistics, semiotics, and law.Commonly it refers to how strictly or loosely an expression is used in describing any particular concept, but it also appears in expressions that indicate the convention or context of the usage.
The genus Strongyloides contains 53 species, [2] [3] and S. stercoralis is the type species. S. stercoralis has been reported in other mammals, including cats and dogs. However, it seems that the species in dogs is typically not S. stercoralis, but the related species S. canis.
a-, an-: Pronunciation: /ə/, /a/, /ən/, /an/.Origin: Ancient Greek: ἀ-, ἀν-(a, an-). Meaning: a prefix used to make words with a sense opposite to that of the ...
The two species are synergistic, and S. thermophilus probably provides L. d. bulgaricus with folic acid and formic acid, which it uses for purine synthesis. [7] S. thermophilus has an optimal growth temperature range of 35–42 °C (95–108 °F), while L. d. bulgaricus has an optimal range of 43–46 °C (109–115 °F). [8]
Streptococcus pneumoniae, or pneumococcus, is a Gram-positive, spherical bacteria, alpha-hemolytic member of the genus Streptococcus. [1] S. pneumoniae cells are usually found in pairs and do not form spores and are non motile. [2]
Like other streptomycetes, S. griseus has a high GC content in its genome, [8] with an average of 72.2%. [9] The species was first classified within the genus Streptomyces by Waksman and Henrici in 1948. [10] The taxonomy of S. griseus and its evolutionarily related strains have been a considerable source of confusion for microbial systematists.
In biology, taxonomic rank (which some authors prefer to call nomenclatural rank [1] because ranking is part of nomenclature rather than taxonomy proper, according to some definitions of these terms) is the relative or absolute level of a group of organisms (a taxon) in a hierarchy that reflects evolutionary
In S. mutans, a peptide pheromone quorum-sensing signaling system controls genetic competence. [67] This system functions optimally when the S. mutans cells are in crowded biofilms. [68] S. mutans cells growing in a biofilm are transformed at a rate 10- to 600-fold higher than single cells growing under uncrowded conditions (planktonic cells). [67]
