Spironucleus Columbae
''Spironucleus'' is a diplomonad genus that is bilaterally symmetrical and can be found in various animal hosts. This genus is a binucleate flagellate, which is able to live in the anaerobic conditions of animal intestinal tracts. A characteristic of ''Spironucleus'' that is common to all metamonads is that it does not have aerobic mitochondria, but instead rely on hydrogenosomes to produce energy. ''Spironucleus'' has six anterior and two posterior flagella. The life cycle of ''Spironucleus'' involves one active trophozoite stage and one inactive cyst stage. ''Spironucleus'' undergoes asexual reproduction via longitudinal binary fission. ''Spironucleus'' ''vortens'' can cause lateral line erosion in freshwater anglefish. ''Spironucleus'' ''columbae'' is found to cause hexamitiasis in pigeons. Finally, ''Spironucleus'' ''muris'' is found to cause illnesses of the digestive system in mice, rats, and hamsters. The genome of ''Spironucleus'' has been studied to exhibit the role of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spironucleus Salmonicida
''Spironucleus salmonicida'' is a species of fish parasite. It is a flagellate adapted to micro-aerobic environments that causes systemic infections in salmonid fish. The species creates foul-smelling, pus-filled abscesses in muscles and internal organs of aquarium fish. In the late 1980s when the disease was first reported, it was believed to be caused by ''Spironucleus barkhanus''. Anders Jørgensen was the person that found out what species really caused the disease. There is a distinct lack of models for diverse microbial eukaryotes. ''Spironucleus salmonicida'' was chosen as a model due to its complex genome and ability to adapt to fluctuating environments. This ability was proven by genetically modifying the pathogen and seeing the results. By comparing these results with the closest model organism, ''Giardia intestinalis'', researchers were able to see that the parasite has a more complex gene regulation system. This system of genetic modification was also used to sequence ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Trophozoite
A trophozoite (G. ''trope'', nourishment + ''zoon'', animal) is the activated, feeding stage in the life cycle of certain protozoa such as malaria-causing ''Plasmodium falciparum'' and those of the ''Giardia'' group. The complementary form of the trophozoite state is the thick-walled microbial cyst, cyst form. They are often different from the cyst stage, which is a protective, dormant form of the protozoa. Trophozoites are often found in the host's body fluids and tissues and in many cases, they are the form of the protozoan that causes disease in the host. In the protozoan, ''Entamoeba histolytica'' it invades the intestinal mucosa of its host, causing dysentery, which aid in the trophozoites traveling to the liver and leading to the production of hepatic abscesses. Life cycle stages ''Plasmodium falciparium'' The causative organism of malaria is a protozoan, ''Plasmodium falciparium'', that is carried by the female Anopheles mosquito, ''Anopheles'' mosquito. Malaria is reco ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prokaryote
A prokaryote (; less commonly spelled procaryote) is a unicellular organism, single-celled organism whose cell (biology), cell lacks a cell nucleus, nucleus and other membrane-bound organelles. The word ''prokaryote'' comes from the Ancient Greek (), meaning 'before', and (), meaning 'nut' or 'kernel'. In the earlier two-empire system arising from the work of Édouard Chatton, prokaryotes were classified within the empire Prokaryota. However, in the three-domain system, based upon molecular phylogenetics, prokaryotes are divided into two domain (biology), domains: Bacteria and Archaea. A third domain, Eukaryote, Eukaryota, consists of organisms with nuclei. Prokaryotes evolution, evolved before eukaryotes, and lack nuclei, mitochondria, and most of the other distinct organelles that characterize the eukaryotic cell. Some unicellular prokaryotes, such as cyanobacteria, form colony (biology), colonies held together by biofilms, and large colonies can create multilayered microbial ...

Anaerobic Metabolic Processes
Anaerobic means "living, active, occurring, or existing in the absence of free oxygen", as opposed to aerobic which means "living, active, or occurring only in the presence of oxygen." Anaerobic may also refer to: * Anaerobic adhesive, a bonding agent that does not cure in the presence of air *Anaerobic respiration, respiration in the absence of oxygen, using some other molecule as the final electron acceptor **Anaerobic organism, any organism whose redox metabolism does not depend on free oxygen **Anammox, anaerobic ammonium oxidation, a globally important microbial process of the nitrogen cycle **Anaerobic filter, an anaerobic digester with a tank containing a filter medium where anaerobic microbes can establish themselves **Anaerobic digestion, the use of anaerobic bacteria to break down waste, with biogas as a byproduct ***Anaerobic clarigester, an anaerobic digester that treats dilute biodegradable feedstocks and allows different retention times for solids and liquids ***Anaer ...
