Kingfishers or Alcedinidae are a family of small to medium-sized, brightly colored birds in the order Coraciiformes. They have a cosmopolitan distribution, with most species found in the tropical regions of Africa, Asia, and Oceania. The family contains 114 species and is divided into three subfamilies and 19 genera. All kingfishers have large heads, long, sharp, pointed bills, short legs, and stubby tails. Most species have bright plumage with only small differences between the sexes. Most species are tropical in distribution, and a slight majority are found only in forests. They consume a wide range of prey usually caught by swooping down from a perch. While kingfishers are usually thought to live near rivers and eat fish, many species live away from water and eat small invertebrates. Like other members of their order, they nest in cavities, usually tunnels dug into the natural or artificial banks in the ground. Some kingfishers nest in arboreal termite nests. A few species, principally insular forms, are threatened with extinction. In Britain, the word "kingfisher" normally refers to the common kingfisher.
Enterococcus is a large genus of lactic acid bacteria of the phylum Firmicutes. Enterococci are gram-positive cocci that often occur in pairs (diplococci) or short chains, and are difficult to distinguish from streptococci on physical characteristics alone. Two species are common commensal organisms in the intestines of humans: E. faecalis (90–95%) and E. faecium (5–10%). Rare clusters of infections occur with other species, including E. casseliflavus, E. gallinarum, and E. raffinosus.
The belted kingfisher is a large, conspicuous water kingfisher. It is depicted on the 1986 series Canadian $5 note. All kingfishers were formerly placed in one family, Alcedinidae, but recent research suggests that this should be divided into three subfamilies.
The common kingfisher, also known as the Eurasian kingfisher and river kingfisher, is a small kingfisher with seven subspecies recognized within its wide distribution across Eurasia and North Africa. It is resident in much of its range, but migrates from areas where rivers freeze in winter.
The river kingfishers or pygmy kingfishers, subfamily Alcedininae, are one of the three subfamilies of kingfishers. The river kingfishers are widespread through Africa and east and south Asia as far as Australia, with one species, the common kingfisher also appearing in Europe and northern Asia. This group includes many kingfishers that actually dive for fish. The origin of the subfamily is thought to have been in Asia.
The pied kingfisher is a species of water kingfisher widely distributed across Africa and Asia. Originally described by Carl Linnaeus in 1758, it has five recognised subspecies. Its black and white plumage and crest, as well as its habit of hovering over clear lakes and rivers before diving for fish, make it distinctive. Males have a double band across the breast, while females have a single gorget that is often broken in the middle. They are usually found in pairs or small family groups. When perched, they often bob their head and flick up their tail.
Geranic acid, or 3,7-dimethyl-2,6-octadienoic acid, is a pheromone used by some organisms. It is a double bond isomer of nerolic acid.
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, but 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.
A diplococcus is a round bacterium that typically occurs in the form of two joined cells.
Lactobacillales are an order of gram-positive, low-GC, acid-tolerant, generally nonsporulating, nonrespiring, either rod-shaped (bacilli) or spherical (cocci) bacteria that share common metabolic and physiological characteristics. These bacteria, usually found in decomposing plants and milk products, produce lactic acid as the major metabolic end product of carbohydrate fermentation, giving them the common name lactic acid bacteria (LAB).
The buff-breasted paradise kingfisher is a bird in the tree kingfisher subfamily, Halcyoninae. It is native to Australia and New Guinea. It migrates in November from New Guinea to its breeding grounds in the rainforest of North Queensland, Australia. Like all paradise kingfishers, this bird has colourful plumage with a red bill, buff breast and distinctive long tail streamers.
The Numfor paradise kingfisher, also known as the cobalt paradise kingfisher, is a tree kingfisher endemic to the Indonesian island of Numfor off the northwestern coast of New Guinea. It is a common species, but the forests where it lives are being affected by logging and the IUCN has rated its conservation status as "near-threatened".
The Biak paradise kingfisher is a tree kingfisher that is endemic to the Indonesian island of Biak which is one of a small group of islands located in Cenderawasih Bay near the northern coast of Papua. This bird has a turquoise-blue back with a white belly and tail streamers and a reddish beak. Its natural habitat is forests and the IUCN has assessed its conservation status as being "near-threatened".
The paradise kingfishers are a group of tree kingfishers endemic to New Guinea — with the exception of two species also present in the Moluccas and Queensland.
The common paradise kingfisher, also known as the Galatea paradise kingfisher and the racquet-tailed kingfisher, is a species of bird in the family Alcedinidae. It is found in subtropical or tropical moist lowland forests of the Maluku Islands and New Guinea. Like all paradise kingfishers, it has a red bill and colourful plumage. The species is common and the IUCN has assessed its conservation status as being of "least concern".
Enterococcus durans is a species of Enterococcus. It is a gram-positive, catalase- and oxidase-negative, coccus bacterium. The organism is also a facultative anaerobic organism. Prior to 1984, it was known as Streptococcus durans.
Lancefield grouping is a system of classification that classifies catalase-negative Gram-positive cocci based on the carbohydrate composition of bacterial antigens found on their cell walls. The system, created by Rebecca Lancefield, was historically used to organize the various members of the family Streptococcaceae, which includes the genera Lactococcus and Streptococcus, but now is largely superfluous due to explosive growth in the number of streptococcal species identified since the 1970s. However, it has retained some clinical usefulness even after the taxonomic changes, and as of 2018, Lancefield designations are still often used to communicate medical microbiological test results in the United States.
Enterococcus haemoperoxidus is a species of Enterococcus with type strain CCM 4851T.
Enterococcus moraviensis is a species of Enterococcus with type strain CCM 4856T.
Enterococcus xinjiangensis is a Gram-positive bacterium from the genus of Enterococcus which has been isolated from yogurt from Xinjiang.
