Indole positive gram negative rod-shaped bacteria include members of the Enterobacteriaceae family such as Escherichia coli and Klebsiella pneumoniae. These bacteria produce indole from the amino acid tryptophan as a metabolic byproduct, which can be detected using the Kovac's reagent test. Indole production is a characteristic used in the identification and differentiation of these bacteria in the laboratory.

Is staphylococcus epidermidis indole positive?
No, Staphylococcus epidermidis is usually indole negative, meaning it does not produce indole as a byproduct of tryptophan metabolism. This can help differentiate it from other bacteria that are indole positive.
Is klebsiella gram positive or negative?
i believe it is a gram bacteria which causes respiratory illness.
Is gram positive bigger than gram negative?
Not necessarily. Gram positive and gram negative bacteria can vary in size depending on the species. Both gram positive and gram negative bacteria can range in size from small cocci to long rod-shaped cells.
Is citrobacter freundii a gram positive or gram negative bacteria?
klebsiella enterobacter citrobacter salmonellaparab
Is proteus gram positive or gram negative?
Proteus is Gram-negative.
Is staphylococcus epidermidis indole positive?

Name the different gram positive and gram negative bacteria?
Name of gram positive and gram negative bacteria?
Does Tetracycline kill gram positive or gram negative bacteria?
Tetracycline kills both gram positive and gram negative bacteria. The mode of action to which Tetracycline works to kill bacteria is that it inhibits protein synthesis which works against both gram positive and gram negative bacteria.
Are archaebacteria gram positive or gram negative?
Archaebacteria are neither gram positive nor gram negative because they do not have peptidoglycan in their cell walls like bacteria. Instead, they have unique cell wall structures that make them distinct from both gram positive and gram negative bacteria.
What colors gram positive and gram negative bacteria?
Gram-positive cells are purple and the Gram-negative cells are red.
Is citrobacter freundii a gram positive or gram negative bacteria?
klebsiella enterobacter citrobacter salmonellaparab
What is the Bacteria in gingivitis is it gram positive or negative?
gram +
Which Gran Positive or negative which is more serious?
Gram positive bacteria responds to the Gram stain; gram negative bacteria does not. The two bacteria do not respond to the same antibiotics. Right now the most dangerous bacteria is a gram negative bacteria. That could change.
Give the example for gram positivegram negative bacteria?
Typical gram-positive bacteria are staphylococci; typical gram-negative bacteria are bacilli.
