Streptococcus is a genus of gram-positive coccus or spherical bacteria that belongs to the family Streptococcaceae, within the order Lactobacillales, in the phylum Firmicutes. 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.
Lynx spider (Oxyopidae) is a family of araneomorph spiders first described by Tamerlan Thorell in 1870. Most species make little use of webs, instead spending their lives as hunting spiders on plants. Many species frequent flowers in particular, ambushing pollinators, much as crab spiders do. They tend to tolerate members of their own species more than most spiders do, and at least one species has been identified as exhibiting social behaviour.
Infective endocarditis is an infection of the inner surface of the heart, usually the valves. Symptoms may include fever, small areas of bleeding into the skin, heart murmur, feeling tired, and low red blood cell count. Complications may include backward blood flow in the heart, the heart struggling to pump a sufficient amount of blood to meet the body's needs, abnormal electrical conduction in the heart, stroke, and kidney failure.
The viridans streptococci are a large group of commensal streptococcal Gram-positive bacteria species that are α-hemolytic, producing a green coloration on blood agar plates. The pseudo-taxonomic term "Streptococcus viridans" is often used to refer to this group of species, but writers who do not like to use the pseudotaxonomic term prefer the terms viridans streptococci, viridans group streptococci (VGS), or viridans streptococcal species.
Hemolysis is the breakdown of red blood cells. The ability of bacterial colonies to induce hemolysis when grown on blood agar is used to classify certain microorganisms. This is particularly useful in classifying streptococcal species. A substance that causes hemolysis is a hemolysin.
Subacute bacterial endocarditis is a type of endocarditis. Subacute bacterial endocarditis can be considered a form of type III hypersensitivity.
Peucetia viridans, the green lynx spider, is a bright-green lynx spider usually found on green plants. It is the largest North American species in the family Oxyopidae. This spider is common in Jamaica.
Grevillea aquifolium is a shrubby or scrambling plant endemic to South Australia and Victoria. Common names include holly grevillea, prickly grevillea or variable prickly grevillea. In occurs naturally in woodland, open forest and heathland.
Gymnopilus viridans is a rarely documented mushroom. It contains the hallucinogens psilocybin and psilocin. The last known collection is from Washington, United States (1912).
The Streptococcus anginosus group (SAG), also known as the anginosus group streptococci (AGS) or the milleri group streptococci (MGS), are a group of several species of streptococci with clinical similarities. The group is named after a principal member species, Streptococcus anginosus. The older name Streptococcus milleri is now pseudotaxonomic, as the idea that these streptococci constituted a single species was incorrect. The anginosus group streptococci are members of the viridans streptococci group. They have been implicated as etiologic agents in a variety of serious purulent infections, but because of their heterogeneous characteristics, these organisms may be unrecognized or misidentified by clinical laboratorians. The unique characteristic of them from other pathogenic streptococci, such as S. pyogenes and S. agalactiae, is their ability to cause abscesses.
Gaffkaemia is a bacterial disease of lobsters, caused by the Gram-positive lactic acid bacterium Aerococcus viridans var. homari.
Aerococcus is a genus in the phylum Firmicutes (Bacteria). The genus was first identified in 1953 from samples of air and dust as a catalase-negative, gram-positive coccus that grew in small clusters. They were subsequently found in hospital environments and meat-curing brines. It has been difficult to identify as it resembles alpha-hemolytic Streptococcus on blood agar plates and is difficult to identify by biochemical means. Sequencing of 16S rRNA has become the gold standard for identification, but other techniques such as MALDI-TOF have also been useful for identifying both the genus and species.
Streptococcus cristatus is a species of viridans Streptococcus with tufted fibrils, first isolated from the human oral cavity and throat. The type strain is strain CR311.
Ericydeus nigropunctatus is a species of the true weevil family.
Thalassomonas is a genus of bacteria from the family Colwelliaceae. Thalassomonas bacteria can cause the coral diseases white plague.
Thalassomonas viridans is a Gram-negative, aerobic and motile bacterium from the genus of Thalassomonas which has been isolated from an oyster from the Mediterranean coast from Spain.
Ericydeus lautus is a species of broad-nosed weevil in the beetle family Curculionidae. It is found in North America.
Ericydeus is a genus of broad-nosed weevils in the beetle family Curculionidae. There are about 16 described species in Ericydeus.
Eucalyptus socialis subsp. viridans, commonly known as the green-leaved red mallee, is a subspecies of mallee that is endemic to south-eastern Australia. It usually has rough bark on the base of the trunk, smooth bark above, lance-shaped adult leaves, flower buds in groups of between seven and eleven, pale creamy yellow flowers and barrel-shaped to urn-shaped or spherical fruit.
