Streptococcus Dentiloxodontae
''Streptococcus'' is a genus of gram-positive ' (plural ) or spherical bacteria that belongs to the family Streptococcaceae, within the order Lactobacillales (lactic acid bacteria), in the phylum Bacillota. Cell division in streptococci occurs along a single axis, so as they grow, they tend to form pairs or chains that may appear bent or twisted. This differs from staphylococci, which divide along multiple axes, thereby generating irregular, grape-like clusters of cells. Most streptococci are oxidase-negative and catalase-negative, and many are facultative anaerobes (capable of growth both aerobically and anaerobically). The term was coined in 1877 by Viennese surgeon Albert Theodor Billroth (1829–1894), by combining the prefix "strepto-" (from ), together with the suffix "-coccus" (from Modern , from .) In 1984, many bacteria formerly grouped in the genus ''Streptococcus'' were separated out into the genera ''Enterococcus'' and ''Lactococcus''. Currently, over 50 species ...

Friedrich Julius Rosenbach
Friedrich Julius Rosenbach, also known as Anton Julius Friedrich Rosenbach, (16 December 1842 – 6 December 1923) was a German physician and microbiologist. He is credited for differentiating ''Staphylococcus aureus'' and ''Staphylococcus albus'', which is now called ''Staphylococcus epidermidis'', in 1884. He also described and named ''Streptococcus pyogenes''. Rosenbach's disease is also named in his honor. Biography Rosenbach was born in Emmerthal, Grohnde an der Weser on 16 December 1842. He studied in Heidelberg, Göttingen, Vienna, Paris, and Berlin. He obtained his doctorate in 1867. He married Franziska Merkel on 12 May 1877. Rosenbach died on 6 December 1923 in Göttingen.

Streptococcus Ferus
Overview ''Streptococcus ferus'' is a facultatively anaerobic, gram-positive species of the genus ''Streptococcus''. The species is a member of the ''Viridans streptococci'' group which are a large mixed-group of mostly alpha-hemolytic streptococci. The alpha-hemolytic bacteria are ones that exhibit a partial hemolysis with green coloration when grown on sheep blood agar (see image.) Ecology ''Streptococcus ferus'' was originally isolated from the oral cavity wild rats who were living in sugar cane fields and eating a high sucrose diet The species name ''ferus'', meaning wild, refers to their association with these animals. More recently the strain has also been isolated from the nasal and oral cavities of pigs. The species has not been identified in any other host organisms. Morphology ''Streptococcus ferus'' are gram positive lanceolate coccobacillus A coccobacillus (plural coccobacilli), or bacilluscocco, is a type of bacterium with a shape intermediate between cocci (sp ...

Streptococcus Faecalis
''Enterococcus faecalis'' – formerly classified as part of the group D ''Streptococcus'' system – is a Gram-positive, commensal bacterium inhabiting the gastrointestinal tracts of humans. Like other species in the genus ''Enterococcus'', ''E. faecalis'' is found in healthy humans and can be used as a probiotic. The probiotic strains such as Symbioflor1 and EF-2001 are characterized by the lack of specific genes related to drug resistance and pathogenesis. As an opportunistic pathogen, ''E. faecalis'' can cause life-threatening infections, especially in the nosocomial (hospital) environment, where the naturally high levels of antibiotic resistance found in ''E. faecalis'' contribute to its pathogenicity. ''E. faecalis'' has been frequently found in reinfected, root canal-treated teeth in prevalence values ranging from 30% to 90% of the cases. Re-infected root canal-treated teeth are about nine times more likely to harbor ''E. faecalis'' than cases of primary infections. Physi ...

Streptococcus Equinus
''Streptococcus equinus'' is a Gram-positive, nonhemolytic, non pathogenic, lactic acid bacterium of the genus ''Streptococcus''. It is the principal ''Streptococcus'' found in the alimentary canal of a horse, and makes up the majority of the bacterial flora in horse feces. Equivalence with ''Streptococcus bovis'' has been contested. History ''S. equinus'', which is always abundant in the feces of horses, was first isolated from the air in 1906 by Andrewes and Horder due to the presence of dried horse manure, common in most cities at the time. In 1910, Winslow and Palmer verified the findings of Andrewes and Horder and reported further findings in both cattle and human feces. Phylogeny After the bacterium was discovered in 1906, the term ''Streptococcus equinus'' became a convenient “wastebasket” into which nonhemolytic streptococci that do not ferment lactose and mannitol were categorized. The classification of all streptococci that fail to ferment lactose into one lar ...

Streptococcus Dysgalactiae
''Streptococcus dysgalactiae'' is a gram positive, beta-haemolytic, coccal bacterium belonging to the family ''Streptococcaceae''. It is capable of infecting both humans and animals, but is most frequently encountered as a commensal of the alimentary tract, genital tract, or less commonly, as a part of the skin flora. The clinical manifestations in human disease range from superficial skin-infections and tonsillitis, to severe necrotising fasciitis and bacteraemia. The incidence of invasive disease has been reported to be rising. Several different animal species are susceptible to infection by ''S. dysgalactiae'', but bovine mastitis and infectious arthritis in lambs (joint ill) have been most frequently reported. ''Streptococcus dysgalactiae'' is currently divided into the subspecies '' Streptococcus dysgalactiae subspecies equisimilis'' and '' Streptococcus dysgalactiae subspecies dysgalactiae''; the former mostly associated with human disease, and the latter almost exclusi ...

Streptococcus Downei
''Streptococcus downei'' is a Gram-positive bacterium Bacteria (; singular: bacterium) are ubiquitous, mostly free-living organisms often consisting of one biological cell. They constitute a large domain of prokaryotic microorganisms. Typically a few micrometres in length, bacteria were amon ..., with type strain MFe28 (NCTC 11391T). It is thought to be cariogenic.
