Neisseriales
The Neisseriaceae are a family of Pseudomonadota, within the '' Neisseriales'' order. While many organisms in the family are mammalian commensals or part of the normal flora, the genus ''Neisseria'' includes two important human pathogens, specifically those responsible for gonorrhea (caused by'' N. gonorrhoeae'') and many cases of meningitis ("meningococcal meningitis", caused by'' N. meningitidis''). As a group, the Neisseriaceae are strictly aerobic and Gram-negative, occur mainly in pairs (diplococci), and typically do not have flagella A flagellum (; ) is a hairlike appendage that protrudes from certain plant and animal sperm cells, and from a wide range of microorganisms to provide motility. Many protists with flagella are termed as flagellates. A microorganism may have f ....

Betaproteobacteria
Betaproteobacteria are a class of Gram-negative bacteria, and one of the eight classes of the phylum Pseudomonadota (synonym Proteobacteria). The ''Betaproteobacteria'' are a class comprising over 75 genera and 400 species of bacteria. Together, the ''Betaproteobacteria'' represent a broad variety of metabolic strategies and occupy diverse environments from obligate pathogens living within host organisms to oligotrophic groundwater ecosystems. Whilst most members of the ''Betaproteobacteria'' are heterotrophic, deriving both their carbon and electrons from organocarbon sources, some are photoheterotrophic, deriving energy from light and carbon from organocarbon sources. Other genera are autotrophic, deriving their carbon from bicarbonate or carbon dioxide and their electrons from reduced inorganic ions such as nitrite, ammonium, thiosulfate or sulfide — many of these chemolithoautotrophic. ''Betaproteobacteria'' are economically important, with roles in maintaining soil pH a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vitreoscilla
''Vitreoscilla'' is a genus of Gram-negative aerobic bacterium. The bacterial haemoglobin ( VHb) was first discovered from ''Vitreoscilla'', and VHb is found to have a wide range of biological and biotechnological applications including promotion of cell growth, protein synthesis, metabolite productivity, respiration, cellular detoxification, fermentation, and biodegradation. Etymology The generic name is derived from the Latin adjective ''vitreus'', which means clear or transparent; and the noun ''oscillum'', meaning a swing. Thus ''Vitreoscilla'' is used to describe the bacterium as the transparent swing or oscillator, the way it exhibits locomotion. Species There are three valid species under the genus, namely *''Vitreoscilla beggiatoides'' Pringsheim 1949 (type species) *''Vitreoscilla filiformis'' (ex Pringsheim 1951) Strohl ''et al.'' 1986 *''Vitreoscilla stercoraria'' Pringsheim 1951 Structure Members of ''Vitreoscilla'' are obligate aerobic bacteria, which ar ...

Eikenella
''Eikenella corrodens'' is a Gram-negative facultative anaerobic bacillus that can cause severe invasive disease in humans. It was first identified by M. Eiken in 1958, who called it ''Bacteroides corrodens''. ''E. corrodens'' is a rare pericarditis associated pathogen. It is a fastidious, slow growing, human commensal bacillus, capable of acting as an opportunistic pathogen and causing abscesses in several anatomical sites, including the liver, lung, spleen, and submandibular region. ''E. corrodens'' could independently cause serious infection in both immunocompetent and immunocompromised hosts. Microbiology ''Eikenella corrodens'' is a pleomorphic bacillus that sometimes appears coccobacillary and typically creates a depression (or "pit") in the agar on which it is growing.
