Taxonomic classification of Proteobacteria
The Taxonomic classification for Proteobacteria is as follow:
Beta Proteobacteria is a type of Proteobacteria that consist of several groups of aerobic or facultative bacteria which are often highly versatile in their degradation capacities, but also contain hemolithotrophic genera and prototroph (ebi.ac).
Identify the threats it represent to humans and / or the environment?
Beta proteobacteria play a role in Nitrogen fixation in various types of plants, oxiding ammonium to produce Nitrate, an important chemical for plant function (ebi.ac). Many of them are found in environment samples such as waste water or soil (ebi.ac).
All pathogenic aerobic gram-negative cocci belong to the Neisseriaceae family, which is composed of 5 genera:
• Moraxella (including 2 subgenera, Moraxella and Branhamella)
Of these, Neisseria includes the most important human pathogens, N. meningitidis and N. gonorrhoeae (Merck). Numerous saprophytic Neisseriaceae commonly inhabit the oropharynx, vagina, or colon but rarely cause human disease(Merck). Moraxella catarrhalis causes otitis media in children and sinusitis. Over half a dozen other Moraxella sp and the related Kingella kingae cause infections in the CNS, respiratory...
