I am gram-positive bacilli... what does this mean??
It is a pleomorphic Gram negative bacilli.
Bacillus anthracis is the Gram positive bacilli nicknamed "boxcars" due to its distinctive morphology resembling rectangular boxcars when viewed under the microscope.
Yes, some gram-negative enteric bacilli can be considered fastidious heterotrophs. This means they have complex nutritional requirements and may require specific growth factors or conditions to thrive. Examples of fastidious enteric bacilli include some strains of Salmonella and Shigella.
Streptobacillus is a gram negative, oxidase negative, catalase negative, non motile organism, and 0.3-0.7 µm by 1-5 µm in lengthEscherichia coliMost of the Enterobacteriaceae are Catalase Positive. E. coli is Catalase Positive and Oxidase Negative. Do not report the previous as an answer. For gram negative, catalase negative and oxidase negative rods, it is likely that you have bacteria of the Bacteroides genus.
Gram-positive bacteria and Gram-negative bacteria are different in their colouration when dyed and viewed with a light microscope. Gram-positive appear violet, and Gram-negative appear red. Gram-positive and Gram-negative classification, however, has nothing to do with size.
Bacilli are usually in rod shaped form. They can consist of gram negative and gram positive bacteria.
Typical gram-positive bacteria are staphylococci; typical gram-negative bacteria are bacilli.
It is a pleomorphic Gram negative bacilli.
First gentian violet or crystal violet solutn is applied,they bcome purple now iodine is added and acetone or ethyl alcohol is applied gram -ve bacteria lose their color while gram positive bacteria don't
Penicillin is NOT effective against gram positive and negative cocci and gram positive bacilli only. it is not effective against rest of the organisms.
Bacillus anthracis is the Gram positive bacilli nicknamed "boxcars" due to its distinctive morphology resembling rectangular boxcars when viewed under the microscope.
many gram positive bacilli
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.
Yes, some gram-negative enteric bacilli can be considered fastidious heterotrophs. This means they have complex nutritional requirements and may require specific growth factors or conditions to thrive. Examples of fastidious enteric bacilli include some strains of Salmonella and Shigella.
One example of a gram-negative bacteria is Escherichia coli (E. coli). Gram-negative bacteria have a cell wall structure that includes an outer membrane, which is not present in gram-positive bacteria. This outer membrane contains lipopolysaccharides that contribute to the bacteria's resistance to certain antibiotics. Gram staining is a common technique used to differentiate between gram-negative and gram-positive bacteria based on their cell wall composition.
You do not " get " them, but gram positive bacteria are gram positive because their cell wall is of sufficient thickness and properly constructed to hold the Gram stain. They have one thick wall of peptidoglycan that holds the stain against being washed away. Gram negative bacteria have two thinner walls which allow the stain to be washed away, basically.
