Gram-positive bacteria. Rod-shaped gram-positive Bacillus anthracis bacteria in a cerebrospinal fluid sample stand out from round white blood cells, which also accept the crystal violet stain. In bacteriology, gram-positive bacteria are bacteria that give a positive result in the Gram stain test, which is traditionally used to quickly classify ...
Diplobacilli: Two bacilli arranged side by side with each other. Streptobacilli: Bacilli arranged in chains. Coccobacillus: Oval and similar to coccus (circular shaped bacterium). [22] There is no connection between the shape of a bacterium and its color upon Gram staining; there are both gram-positive rods and gram-negative rods.
Bacillus (Latin "stick") is a genus of Gram-positive, rod-shaped bacteria, a member of the phylum Bacillota, with 266 named species. The term is also used to describe the shape (rod) of other so-shaped bacteria; and the plural Bacilli is the name of the class of bacteria to which this genus belongs. Bacillus species can be either obligate ...
Gram staining is a bacteriological laboratory technique [7] used to differentiate bacterial species into two large groups (gram-positive and gram-negative) based on the physical properties of their cell walls. [8][page needed] Gram staining can also be used to diagnose a fungal infection. [1]
Turicella Funke et al. 1994. Corynebacterium (/ kɔːˈraɪnəbækˌtɪəriəm, - ˈrɪn -/) is a genus of Gram-positive bacteria and most are aerobic. They are bacilli (rod-shaped), and in some phases of life they are, more specifically, club -shaped, which inspired the genus name (coryneform means "club-shaped").
Bacilli. Bacilli is a taxonomic class of bacteria that includes two orders, Bacillales and Lactobacillales, which contain several well-known pathogens such as Bacillus anthracis (the cause of anthrax). Bacilli are almost exclusively gram-positive bacteria. [1] The name Bacillus, capitalized and italicized, refers to a specific genus of bacteria.
Bacillus subtilis (/ bəˈsɪl.əs subˈtiː.lis /), [3][4] known also as the hay bacillus or grass bacillus, is a gram-positive, catalase -positive bacterium, found in soil and the gastrointestinal tract of ruminants, humans and marine sponges. [5][6][7][8] As a member of the genus Bacillus, B. subtilis is rod-shaped, and can form a tough ...
Lactobacillus is a genus of gram-positive, aerotolerant anaerobes or microaerophilic, rod-shaped, non-spore-forming bacteria. [2] [3] Until 2020, the genus Lactobacillus comprised over 260 phylogenetically, ecologically, and metabolically diverse species; a taxonomic revision of the genus assigned lactobacilli to 25 genera (see § Taxonomy below).
