Yes. They are.
Answerno, it is a gram positive
There are a variety of bacteria that can cause foodborne illness: some are Gram-positive, others are Gram-negative. See Related Links.
Salmonella bacteria are rod-shaped, gram-negative organisms that typically appear as tiny, colorless colonies on agar plates. Under a microscope, they can be seen as small, motile rods with flagella. In food or water, Salmonella cannot be visually detected without specialized equipment.
Salmonella is a genus of rod-shaped, gram-negative bacteria, not a bacillus. The two main species of Salmonella that are of concern to humans are Salmonella enterica and Salmonella bongori. These bacteria can cause foodborne illnesses in humans.
Escherichia coli (E. coli) and Salmonella are both Gram-negative bacteria, which means they have a thinner peptidoglycan layer and an outer membrane that can prevent the crystal violet stain used in Gram staining from penetrating effectively. As a result, they do not retain the violet stain and appear pink after the counterstain is applied, indicating their Gram-negative status. Gram staining is still applicable to these bacteria; however, their Gram-negative characteristics are revealed rather than obscured.
Salmonella typhimurium is a Gram-negative, rod-shaped bacterium.
Gram Negative.
It is gram negative
because it has a negative affect on people
Gram-Negative Bacteria!
Answerno, it is a gram positive
There are currently no antonyms for the work salmonella. Salmonella is a gram-negative bacteria that appears rod-shaped under a microscope.
Salmonella, Shigella, Yersinia, and Serratia are all gram-negative facultatively anaerobic rods.
is salmonella typhi a gram negative bacteria or coccobacilli
Typhoid is caused by Salmonella typhimurium, also called as Salmonella typhi. This is gram negative rod shaped bacteria.
I think you mean gram negative bacilli. They get their name as those who do not retain crystal violet dye in the gram staining protocol. Many gram negative bacteria are pathenogenic or disease causing. e-coli and salmonella are gram negative bacteria.
