They can be round (cocci), in clusters of four (micrococcus), chains (Streptococcus spp) or rod shaped called bacilli. C. perfinges is rod shaped. There are also a few branched types such as Nocardia.

∙ 15y agogram positive cell wall contain 90% peptidoglycan so if we give gram staining to this kind of bacteria, we will get purple color for the bacteria. gram negative cell wall contain 10% peptidoglycan so if we give gram staining to this kind of bacteria, we will get the red color because the crystal violet can't stick with the cell wall.

∙ 12y agonot necessarily it just means it mas more peptidoglycan in its cell wall
Wiki User
∙ 12y agoIt is a single thick layer of peptidoglycan. This is why the Gram stain is held in the wall of this type bacteria. Google peptidoglycan.

Is proteus hauseri gram positive or gram negative?
A Gram negative pathogen. This means it has two thinner petidoglycan cell walls.

Gram positive !!
What colors do gram-positive and gram-negative bacteria stain?
Gram positive are purple. Just remember Positive+Purple. Gram negative are a reddish color from the safranin. After using the crystal violet, the grams iodine acts as a mordant to hold color on cell wall. When using the alcohol, the gram positive will stay purple while the gram negative will become clear. This is due to the outer cell wall of the gram negative specimen (lipopolysaccharide) basically being stripped by the alcohol, so now you have a clear specimen again. When you add the safranin it sticks to the gram negative cell wall, hince the red/pink color.
Are coliforms gram-positive or gram negative?
Gram negative
Is HIV gram positive or gram negative?
HIV is a virus and, therefore, is neither Gram positive nor Gram negative. The Gram stain is used to identify bacteria as either Gram negative or positive, depending upon the type of cell wall the bacteria has. The Gram stain cannot be used on viruses.
Are human cells gram positive?
Human cells are Gram-negative because they do not contain certain structures. More simply, if they don't have a cell wall they cannot be Gram-positive.
Is cholera gram negative or gram positive?
