Cocci can grow in pairs, chains, or clusters, depending on their orientation and attachment during cell division. In contrast to many bacilli-shaped bacteria, most cocci bacteria do not have flagella and are non-motile. [5] Cocci is an English loanword of a modern or Neo-Latin noun, which in turn stems from the Greek masculine noun κόκκος ...
Vagococcus is a genus of gram-positive bacteria. They are motile or nonmotile cocci which do not form spores. [2] The name Vagococcus comes from Latin adjective vagus meaning wandering; and the Greek noun coccus a grain or berry, Vagococcus - wandering coccus, because Vagococcus fluvialis and some other Vagococcus species are motile, an unusual property for a lactic acid bacteria.
It is described using terms like brittle, creamy, sticky and dry. Staphylococci are considered to have a creamy consistency, [1]: 173 while some Neisseria species are sticky, and colonies of diphtheroid bacteria and beta-hemolytic streptococci are typically dry. [1]: 167–8 Bacteria that produce capsules often have a slimy (mucoid) consistency.
Enterococcus is a large genus of lactic acid bacteria of the phylum Bacillota.Enterococci are Gram-positive cocci that often occur in pairs or short chains, and are difficult to distinguish from streptococci on physical characteristics alone. [2]
Reproduction of T. namibiensis occurs on a single plane; the cocci (a spherical bacterial cell) divide into a diplococcus or streptococcus arrangement. [13] [42] A diplococcus is a pair of cocci cells that can form chains, and streptococcus is a grape-like cluster of cells. [43] In the case of T. namibiensis, a diplococci structure is observed ...
In gram-positive bacteria, the S-layer is attached to the peptidoglycan layer. Gram-negative bacteria's S-layer is attached directly to the outer membrane. Specific to gram-positive bacteria is the presence of teichoic acids in the cell wall. Some of these are lipoteichoic acids, which have a lipid component in the cell membrane that can assist ...
The bacteria are mesophilic and grow best at temperatures between 35 and 37 °C. [1] H. influenzae was first described in 1893 [2] [3] by Richard Pfeiffer during an influenza pandemic [4] when he incorrectly identified it as the causative microbe, which is why the bacteria was given the name "influenzae".
Sarcina is a genus of Gram-positive cocci bacteria in the family Clostridiaceae. [2] [3] [4] A synthesizer of microbial cellulose, [5] various members of the genus are human flora and may be found in the skin [6] and large intestine. [7]
