What is the colony morphology of Enterobacter cloacae?
Enterobacter cloacae on Blood Agar Large, smooth, flat colonies with entire margin without beta hemolysis.
What is the colony morphology of Bacillus cereus?
cereus colonies are large, feathery, dull, gray, granular, spreading colonies, and opaque with a rough matted surface and irregular perimeters. On blood agar, it is beta-hemolytic. Colony perimeters are irregular and represent the configuration of swarming from the site of initial inoculation, perhaps due to B.
What is the morphology of Enterobacter?
Morphology. Members of the Enterobacteriaceae are bacilli (rod-shaped), and are typically 1–5 μm in length. They typically appear as medium to large-sized grey colonies on blood agar, although some can express pigments. Most have many flagella used to move about, but a few genera are nonmotile.
What is Enterobacter aerogenes morphology?
Klebsiella aerogenes, previously known as Enterobacter aerogenes, is a Gram-negative, oxidase negative, catalase positive, citrate positive, indole negative, rod-shaped bacterium. The bacterium is approximately 1-3 microns in length, and is capable of motility via peritrichous flagella.
What is the morphology for B. subtilis?
Bacillus subtilis is a typical germ, which is rod-shaped and Gram-positive. When cultured on ordinary nutrient agar, the morphology circular colony of this bacteria is rough, opaque, fuzzy white or slightly yellow with jagged edges [1, 7].
What is cell morphology?
Cell morphology describes the shape, structure, form, and size of cells. Studies show that cells isolated from multicellular structures (tissues, organs) and cultured as monolayers, change their morphology from e.g. spherical to spindle-like, elongated shapes.
What is the morphology for B subtilis?
What is the arrangement and cell morphology of B subtilis?
Like all members of the genus Bacillus, B. subtilis is a rod-shaped bacterium that typically forms small clumps, short chains, or single cells. It has a cell wall that is made of a complex molecule called peptidoglycan, which is made of long chains of glucose linked together by amino acids.
What arrangement is B cereus?
Summary: Bacillus cereus is a Gram-positive aerobic or facultatively anaerobic, motile, spore-forming, rod-shaped bacterium that is widely distributed environmentally.
