Proteus Hauseri

	Proteus Hauseri ''Proteus hauseri'' is a Gram-negative, facultatively anaerobic, rod-shaped bacterium. Identification Similar to other members of the Enterobacterales order, ''Proteus hauseri'' is oxidase negative, catalase positive, glucose fermenting, and nitrate reducing. ''P. hauseri'' is ONPG negative and PDA positive . Unlike the more commonly seen species of ''Proteus'', ''P. hauseri'' is also able to convert tryptophan into indole, resulting in a positive indole test. ''P. hauser''i shares a similar biochemical profile with ''Proteus vulgaris ''Proteus vulgaris'' is a rod-shaped, nitrate-reducing, indole-positive and catalase-positive, hydrogen sulfide-producing, Gram-negative bacterium that inhabits the intestinal tracts of humans and animals. It can be found in soil, water, and ...'' but can be differentiated by its ability to produce acid from trehalose. Most strains of ''P. hauseri'' demonstrate swarming motility, often covering the entire plate onto which it is inoculated. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
picture info	Gram-negative Bacteria Gram-negative bacteria are bacteria that, unlike gram-positive bacteria, do not retain the Crystal violet, crystal violet stain used in the Gram staining method of bacterial differentiation. Their defining characteristic is that their cell envelope consists of a thin peptidoglycan gram-negative cell wall, cell wall sandwiched between an inner (Cytoplasm, cytoplasmic) Cell membrane, membrane and an Bacterial outer membrane, outer membrane. These bacteria are found in all environments that support life on Earth. Within this category, notable species include the model organism ''Escherichia coli'', along with various pathogenic bacteria, such as ''Pseudomonas aeruginosa'', ''Chlamydia trachomatis'', and ''Yersinia pestis''. They pose significant challenges in the medical field due to their outer membrane, which acts as a protective barrier against numerous Antibiotic, antibiotics (including penicillin), Detergent, detergents that would normally damage the inner cell membrane, and the ...

	Enterobacterales Enterobacterales is an order of Gram-negative bacteria, Gram-negative, non-spore forming, Facultative anaerobic organism, facultatively anaerobic, rod-shaped bacteria with the class Gammaproteobacteria. The type genus of this order is ''Enterobacter.'' The name Enterobacterales is derived from the Latin term ''Enterobacter'', referring the type genus of the order and the suffix "-ales", an ending used to denote an order. Together, Enterobacterales refers to an order whose nomenclatural type is the genus ''Enterobacter''. Historical Identification and Systematics Enterobacterales was proposed in 2005 under the name "Enterobacteriales". However, the name "Enterobacteriales" was not validated according to the rules of the ''International Code of Nomenclature of Prokaryotes,'' thus it lacked standing in nomenclature, so the name was written in parentheses. "Enterobacteriales" was a monotypic order, containing only the family ''Enterobacteriaceae'', and shared its type genus ''Esch ...

	Proteus Vulgaris ''Proteus vulgaris'' is a rod-shaped, nitrate-reducing, indole-positive and catalase-positive, hydrogen sulfide-producing, Gram-negative bacterium that inhabits the intestinal tracts of humans and animals. It can be found in soil, water, and fecal matter. It is grouped with the Morganellaceae and is an opportunistic pathogen of humans. It is known to cause wound infections and other species of its genera are known to cause urinary tract infections. ''P. vulgaris'' was one of the three species Hauser isolated from putrefied meat and identified (1885). Over the past two decades, the genus ''Proteus'', and in particular ''P. vulgaris'', has undergone a number of major taxonomic revisions. In 1982, ''P. vulgaris'' was separated into three biogroups on the basis of indole production. Biogroup one was indole negative and represented a new species, ''P. penneri'', while biogroups two and three remained together as ''P. vulgaris''. Lab identification According to laborator ...

picture info	Bacteria Described In 2000 Bacteria (; : bacterium) are ubiquitous, mostly free-living organisms often consisting of one biological cell. They constitute a large domain of prokaryotic microorganisms. Typically a few micrometres in length, bacteria were among the first life forms to appear on Earth, and are present in most of its habitats. Bacteria inhabit the air, soil, water, acidic hot springs, radioactive waste, and the deep biosphere of Earth's crust. Bacteria play a vital role in many stages of the nutrient cycle by recycling nutrients and the fixation of nitrogen from the atmosphere. The nutrient cycle includes the decomposition of dead bodies; bacteria are responsible for the putrefaction stage in this process. In the biological communities surrounding hydrothermal vents and cold seeps, extremophile bacteria provide the nutrients needed to sustain life by converting dissolved compounds, such as hydrogen sulphide and methane, to energy. Bacteria also live in mutualistic, commensal and parasi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
