Are cyanobacteria classified as gram-negative bacteria?
Yes, cyanobacteria are classified as gram-negative bacteria. This classification is based on the structure of their cell walls, which contain a thin layer of peptidoglycan surrounded by an outer membrane. When stained using the Gram staining technique, cyanobacteria appear pink or red under a microscope, indicating that they do not retain the crystal violet stain and are therefore gram-negative.
Is the acid fast staining result positive or negative for the sample?
The acid-fast staining result for the sample is positive.
What is the difference between positive staining and negative staining based on the structure external to the cell wall?
positive stain stick with specimen and gives it's color where as negative dye doesn't stick with the specimen but settle around it's outer boundary and forming a silhouette. that negative stain produce a dark back ground around the cell.
What are 3 main types of eubacteria?
The three main types of eubacteria are gram-positive bacteria, gram-negative bacteria, and cyanobacteria. Gram-positive bacteria have a thick cell wall that retains the crystal violet stain in the Gram staining method. Gram-negative bacteria have a thinner cell wall and do not retain the stain. Cyanobacteria, also known as blue-green algae, are photosynthetic bacteria capable of oxygenic photosynthesis.
What are the three main groups of bacteria?
The three main groups of bacteria are Gram-positive bacteria, Gram-negative bacteria, and cyanobacteria. Gram-positive bacteria have a thick cell wall that retains the crystal violet stain in the Gram staining technique, while Gram-negative bacteria have a thinner cell wall. Cyanobacteria are photosynthetic bacteria capable of producing oxygen through photosynthesis.

Is the acid fast staining result positive or negative for the sample?
The acid-fast staining result for the sample is positive.
Candida albicans gram positive or gram negative?
Candida albicans is a yeast and belongs to the fungal kingdom, so it does not have a gram classification like bacteria. Gram staining is a technique used to differentiate between gram-positive and gram-negative bacteria based on the composition of their cell walls.
Is plasmodium gram negative?
Plasmodium is not a bacteria to be classified whether gram negative or gram positive. It is a genus of parasitic protists. Infection by these organisms is known as malaria.
What is the difference between positive staining and negative staining based on the structure external to the cell wall?
positive stain stick with specimen and gives it's color where as negative dye doesn't stick with the specimen but settle around it's outer boundary and forming a silhouette. that negative stain produce a dark back ground around the cell.

Is anthrax gram positive or negative?
Anthrax is a gram-positive bacterium, meaning it retains the crystal violet stain in the Gram staining procedure.
Is Entamoeba histolytica gram positive or gram negative?
Bacteria are gram positive and gram negative (which means if you apply Gram stain to them, they either pick up the color (positive) or they do not (negative). Entamoeba Hystolytica is not a bacteria, it is a protozoa (one celled organism) that usually causes diarrhea and can be diagnosed from a stool sample and treated with drugs.
What are the three main groups of bacteria?
The three main groups of bacteria are Gram-positive bacteria, Gram-negative bacteria, and cyanobacteria. Gram-positive bacteria have a thick cell wall that retains the crystal violet stain in the Gram staining technique, while Gram-negative bacteria have a thinner cell wall. Cyanobacteria are photosynthetic bacteria capable of producing oxygen through photosynthesis.
What is Phylum Gram-Positive?
Gram-positive is a classification of bacteria based on their cell wall structure. Bacteria in the phylum Firmicutes are typically Gram-positive, meaning they retain the crystal violet stain in the Gram staining technique. Gram-positive bacteria have a thick layer of peptidoglycan in their cell walls, which gives them their characteristic staining property and contributes to their resilience.
Are yeast cells gram positive or gram negative?
Yeast cells are usually classified as gram-positive because they have a thick cell wall composed of chitin and beta-glucans, similar to other fungi. However, yeast cells may not always adhere strictly to the gram staining classification due to variations in cell wall composition.
What is the other name for Negative staining?
Negative staining is also known as indirect staining because the stain does not directly interact with the specimen.
