What does gram negative on a serratia marcescens gram stain mean?
Bacteria are gram positive or gram negative. Serratia happens to be a gram negative bacteria. They appear pink on a gram stain. Gram positive bacteria stain to a purple color on a gram stain. We can classify and ID bacteria using their gram stain and shape. Some antibiotics only work on gram negative bacteria and some only work on gram positive bacteria. It helps a doctor know which antibiotic to use.
Is azospirillum a gram positive bacteria?
Gram positive
Are most pathogenic bacteria gram-negative?
No, not all pathogenic bacteria are gram-negative. Pathogenic bacteria can be either gram-negative or gram-positive, depending on their cell wall structure. Some common gram-negative pathogenic bacteria include Escherichia coli, Pseudomonas aeruginosa, and Neisseria meningitidis, while some gram-positive pathogenic bacteria include Staphylococcus aureus, Streptococcus pneumoniae, and Enterococcus faecalis.
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.
Is TB a gram negative bacteria?

Give the example for gram positivegram negative 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.

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.
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.
