What s the morphology of bacillus cereus in egative stain?
In a negative stain, Bacillus cereus typically appears as large, rod-shaped (bacillus) cells that may be arranged singly, in pairs, or in short chains. The negative staining technique highlights the bacterial cells against a dark background, allowing for clear visualization of their overall shape and size. Spores may also be observed as clear areas within the rods, indicating the species' ability to form endospores. The morphology is crucial for identifying and differentiating Bacillus cereus from other bacteria.
What is the difference in colony morphology between bacillus cereus bacillus megaterium and bacillus subtilis?
Bacillus cereus typically forms large, flat, and irregular colonies with a rough texture and a translucent to opaque appearance. Bacillus megaterium produces larger colonies that are often circular, smooth, and can have a glossy surface. In contrast, Bacillus subtilis colonies are usually smaller, more spreading, and may appear rough or undulate, often exhibiting a characteristic matte texture. Overall, the differences in size, shape, and surface texture help distinguish these three Bacillus species in culture.
Which agar and broth used for bacillus cereus for cultivation?
Polymyxin B is the agar and broth that is used for bacillus cereus for cultivation.
Is bacillus cereus lactose positive?
No
Is bacillus cereus susceptable or resistant to erythromycin?
Bacillus cereus is generally susceptible to erythromycin. However, it's important to note that antibiotic susceptibility can vary, so it's recommended to perform a susceptibility test to confirm the effectiveness of erythromycin against a specific strain of Bacillus cereus.

How can you test bacillus megatrium from bacillus cereus?
bacillus megatarium test positive for sucrose where creus doesnt
Who discovered bacillus cereus?
Bacillus cereus is a Gram positive, soil dwelling ,beta hemolytic , endemic bacterium. It causes food borne diseases.It is a facultative anaerobe and like other members of the genus Bacillus,, produces endospores.
