	Naegleria ''Naegleria'' is a free living amoebae protist genus consisting of 47 described species often found in warm aquatic environments as well as soil habitats worldwide. It has three life cycle forms: the amoeboid stage, the cyst stage, and the flagellated stage, and has been routinely studied for its ease in change from amoeboid to flagellated stages. The ''Naegleria'' genera became famous when ''Naegleria fowleri'', a human pathogenic strain and the causative agent of primary amoebic meningoencephalitis (PAM), was discovered in 1965. Most species in the genus, however, are non pathogenic. Etymology The genus ''Naegleria'' is named after the German protozoologist, Kurt Nägler. History In 1899, Franz Schardinger discovered an amoeba that had the ability to transform into a flagellated stage. He named the organism ''Amoeba gruberi'', which was later changed to the genus ''Naegleria'' in 1912 by Alexeieff. Before 1970, the genus was generally used as a model organism to study th ...

picture info	Microbiology Microbiology () is the scientific study of microorganisms, those being unicellular (single cell), multicellular (cell colony), or acellular (lacking cells). Microbiology encompasses numerous sub-disciplines including virology, bacteriology, protistology, mycology, immunology, and parasitology. Eukaryotic microorganisms possess membrane-bound organelles and include fungi and protists, whereas prokaryotic organisms—all of which are microorganisms—are conventionally classified as lacking membrane-bound organelles and include Bacteria and Archaea. Microbiologists traditionally relied on culture, staining, and microscopy. However, less than 1% of the microorganisms present in common environments can be cultured in isolation using current means. Microbiologists often rely on molecular biology tools such as DNA sequence based identification, for example the 16S rRNA gene sequence used for bacteria identification. Viruses have been variably classified as organisms, as they have ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Infection And Immunity ''Infection and Immunity'' is a peer-reviewed medical journal published by the American Society for Microbiology. It focuses on interactions between bacterial, fungal, or parasitic pathogens and their hosts. Areas covered include molecular pathogenesis, cellular microbiology, bacterial infection, host responses and inflammation, fungal and parasitic infections, microbial immunity and vaccines, and molecular genomics. The journal publishes primary research articles, editorials, commentaries, minireviews, and a spotlight report highlighting articles of particular interest selected by the editors. Articles are freely accessible after 6 months (delayed open access). Through its "Global Outreach Program," free online access is available to qualified microbiologists in eligible developing countries. History The journal was established in 1970. Prior to that time, original research articles covering topics in infection and immunity were published in a section of the ''Journal of Bacterio ...

	Percolozoa The Percolozoa are a group of colourless, non-photosynthetic Excavata, including many that can transform between amoeboid, flagellate, and cyst stages. Characteristics Most Percolozoa are found as bacterivores in soil, fresh water and occasionally in the ocean. The only member of this group that is infectious to humans is ''Naegleria fowleri'', the causative agent of the often fatal disease amoebic meningitis. The group is closely related to the Euglenozoa, and share with them the unusual characteristic of having mitochondria with discoid cristae. The presence of a ventral feeding groove in the flagellate stage, as well as other features, suggests that they are part of the Excavata group. The amoeboid stage is roughly cylindrical, typically around 20-40 μm in length. They are traditionally considered lobose amoebae, but are not related to the others, and unlike them, do not form true lobose pseudopods. Instead, they advance by eruptive waves, where hemispherical bulges a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
