What else can I help you with?
Is klebsiella gram positive or negative?
i believe it is a gram bacteria which causes respiratory illness.
Is metronidazole gram negative or positive?
It has an effect on both gram negative and gram positive bacteria, however it only affects anaerobic bacteria, not aerobic. It has severe adverse effects when consumed with alcohol.
Is phenylethyl alcohol agar differentia or selective?
Phenylethyl alcohol agar is a selective medium used for the isolation of gram-positive bacteria as it inhibits the growth of gram-negative bacteria. It is not typically used for differentiation purposes.
What is the appearance of gram negative bacteria after addition of mordant in the gram stain?
After the addition of mordant in the Gram stain, gram-negative bacteria will appear red or pink under the microscope. This is because the mordant helps to fix the crystal violet stain to the cell wall of gram-positive bacteria, making it harder for the decolorizer to remove it from the thicker peptidoglycan layer of gram-positive bacteria.
What is the structural difference in the cell walls of gram-negative bacteria that distinguishes them from gram-positive bacteria?
Gram-negative bacteria have a thinner peptidoglycan layer in their cell walls compared to gram-positive bacteria. Additionally, gram-negative bacteria have an outer membrane that contains lipopolysaccharides, which is absent in gram-positive bacteria.
Finctions of alcohol in gram staining?
alcohol is organic solvent , it dissolves lipid in cell wall of Gram negative bacteria . this allows out flow of C.V. and counter staining by safranine which results in red color of Gram negative bacteria .
Is klebsiella gram positive or negative?
i believe it is a gram bacteria which causes respiratory illness.
In a gram stain if alcohol is left out what color would a Gram-negative bacterium turn out?
If alcohol is left out during a Gram stain procedure, a Gram-negative bacterium would appear purple after the addition of the counterstain (safranin). This is because the alcohol step is necessary to remove the crystal violet-iodine complex in Gram-positive bacteria, but without it, the purple color remains in both Gram-negative and Gram-positive bacteria.
Is metronidazole gram negative or positive?
It has an effect on both gram negative and gram positive bacteria, however it only affects anaerobic bacteria, not aerobic. It has severe adverse effects when consumed with alcohol.
What would happen to gram negative bacteria if the alcohol wash step was omitted?
They would be purple.
Is phenylethyl alcohol agar differentia or selective?
Phenylethyl alcohol agar is a selective medium used for the isolation of gram-positive bacteria as it inhibits the growth of gram-negative bacteria. It is not typically used for differentiation purposes.

Give the example for gram positivegram negative bacteria?
Typical gram-positive bacteria are staphylococci; typical gram-negative bacteria are bacilli.
What is the structural difference in the cell walls of gram-negative bacteria that distinguishes them from gram-positive bacteria?
Gram-negative bacteria have a thinner peptidoglycan layer in their cell walls compared to gram-positive bacteria. Additionally, gram-negative bacteria have an outer membrane that contains lipopolysaccharides, which is absent in gram-positive bacteria.
Do gram negative bacteria possess lipopolysaccharides?
Yes, gram-negative bacteria possess lipopolysaccharides.
Are endotoxins produced by gram-negative bacteria?
Yes, endotoxins are produced by gram-negative bacteria.
What diseases are caused by bacteria gram negative?
pneumonia is a disease caused by the gram negative bacteria
