Coccus bacteria genus
WebAbstract. Arthrobacter is a genus of obligate aerobes bacteria characterized by a rod–coccus growth cycle. Arthrobacter spp. commonly are found in soils, aerial surface of plants, and wastewater sediments; they do not form endospores and are highly proteolytic. Recently, Arthrobacter spp. have been isolated from archaeological mural paintings ... Cocci may occur as single cells or remain attached following cell division. Those that remain attached can be classified based on cellular arrangement: Diplococci are pairs of cocci (e.g. Streptococcus pneumoniae and Neisseria gonorrhoeae)Streptococci are chains of cocci (e.g. Streptococcus pyogenes).Staphylococci are … See more A coccus (plural cocci) is any bacterium or archaeon that has a spherical, ovoid, or generally round shape. Bacteria are categorized based on their shapes into three classes: cocci (spherical-shaped), bacillus (rod … See more The cell wall structure for cocci may vary between gram-positive (thick peptidoglycan layers) and gram-negative (thin peptidoglycan layers). While living in their host organism, cocci can be pathogenic (e.g., streptococcus), commensal, or … See more The gram-positive cocci are a large group of loosely bacteria with similar morphology. All are spherical or nearly so, but they vary considerably in size. Members of some genera are identifiable by the way cells are attached to one another: in pockets, … See more
