STR analysis is a tool in forensic analysis that evaluates specific STR regions found on nuclear DNA. The variable (polymorphic) nature of the STR regions that are analyzed for forensic testing intensifies the discrimination between one DNA profile and another. [3] Scientific tools such as FBI approved STRmix incorporate this research technique.
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]
This is called the CAMP test. Streptococcus agalactiae displays this property. Clostridium perfringens can be identified presumptively with this test. Listeria monocytogenes is also positive on sheep's blood agar. Alpha-hemolytic S. viridans (right) and beta-hemolytic S. pyogenes (left) streptococci growing on blood agar
The plural term group B streptococci (referring to the serotypes) and the singular term group B streptococcus (referring to the single species) are both commonly used synonymously with S. agalactiae even though S. halichoeri and S. pseudoporcinus are also group B Streptococci. These species test positive as group B, but are not frequently ...
S. bovis is a human pathogen that has been implicated as a causative agent of endocarditis, [7] urinary tract infections, and more rarely, sepsis and neonatal meningitis. [ 14 ] [ 15 ] [ 16 ] S. bovis has long been associated with colorectal cancer ; [ 8 ] [ 17 ] however, not all genospecies are associated equally.
Streptococcus pneumoniae can be differentiated from the viridans streptococci, some of which are also alpha-hemolytic, using an optochin test, as S. pneumoniae is optochin-sensitive. S. pneumoniae can also be distinguished based on its sensitivity to lysis by bile, the so-called "bile solubility test".

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.
