Hirudo medicinalis, the European medicinal leech, is one of several species of leeches used as "medicinal leeches".
Aeromonas is a genus of Gram-negative, facultative anaerobic, rod-shaped bacteria that morphologically resemble members of the family Enterobacteriaceae. Most of the 14 described species have been associated with human diseases. The most important pathogens are A. hydrophila, A. caviae, and A. veronii biovar sobria. The organisms are ubiquitous in fresh and brackish water.
Epsilonproteobacteria are a class of Proteobacteria. All species of this class are, like all Proteobacteria, Gram-negative.
Mycobacterium conceptionense is a non pigmented rapidly growing mycobacterium was first isolated from wound liquid outflow, bone tissue biopsy, and excised skin tissue from a 31-year-old woman who suffered an accidental open right tibia fracture and prolonged stay in a river. Etymology: conceptionense, pertaining to Hôpital de la Conception, the hospital where the first strain was isolated.
Mycobacterium hiberniae is a species of the phylum Actinobacteria, belonging to the genus Mycobacterium.
Mycobacterium montefiorense is a species of bacteria which cause granulomatous skin disease of moray eels. Sequence analysis, of the 16S rRNA gene reveals M. montefiorense is most closely related to Mycobacterium triplex, an opportunistic pathogen of humans.
Leeches are segmented parasitic or predatory worms that belong to the phylum Annelida and comprise the subclass Hirudinea. They are closely related to the oligochaetes, which include the earthworms, and like them have soft, muscular, segmented bodies that can lengthen and contract. Both groups are hermaphrodites and have a clitellum, but leeches typically differ from the oligochaetes in having suckers at both ends and in having external annulations that do not correspond with their internal segmentation. The body is relatively solid, and the spacious body cavity found in other annelids, the coelom, is reduced to small channels.
Castellaniella caeni is a Gram-negative, oxidase-positive, catalase-negative, facultatively anaerobic, denitrifying, nonmotile bacterium from the genus Castellaniella, isolated from the sludge of the aerobic treatment tanks of a municipal leachate treatment plant in Daejeon in the Republic of Korea.
Castellaniella daejeonensis is a Gram-negative, oxidase and catalase-positive, facultatively anaerobic, non-spore-forming, motile bacterium from the genus Castellaniella, isolated from oil-contaminated soil.
Castellaniella ginsengisoli is a Gram-negative, oxidase- and catalase-positive, rod-shaped, motile, beta-glucosidase-producing bacterium from the genus Castellaniella which has been isolated from soil of a ginseng field in South Korea. Colonies of Castellaniella ginsengisoli are yellow coloured.
Hirudo orientalis is a species of medicinal leech. It has confused with Hirudo medicinalis, but has recently been recognized as different species. This Asian species is associated with mountainous areas in the subboreal eremial zone and occurs in Azerbaijan, Iran, Uzbekistan and Kazakhstan. It occurs also in Georgia, and probably in Armenia.
Dietzia papillomatosis is a bacterium from the genus of Dietzia which has been isolated from the skin scrapings of a patient in the United Kingdom.
Kaistia is a genus of bacteria from the family of Methylocystaceae.
Kaistia hirudinis is a Gram-negative and rod-shaped bacterium from the genus of Kaistia which has been isolated from a leech from the Leech Breeding Station in Biebertal in Germany.
Flavobacterium cutihirudinis is a Gram-negative bacterium from the genus of Flavobacterium which has been isolated from the skin of a leech Hirudo verbana from Biebertal in Germany.
Mucinivorans is an anaerobic bacterial genus from the family of Rikenellaceae with one known species. Mucinivorans hirudinis has been isolated from the digestrive tract of the leech Hirudo verbana.
Castellaniella fermenti is a Gram-negative and aerobic bacterium from the genus Castellaniella which has been isolated from fermented food from Taiwan.
Niabella drilacis is a Gram-negative and rod-shaped bacterium from the genus of Niabella which has been isolated from a leech from Biebertal in Germany.
