Gram-positive bacteria examples and diseases The table below describes various Gram-positive bacteria, their basic morphological features the diseases they cause in Humans. Gram-positive bacteria antibiotics As noted from the above table, Gram-positive bacteria are known to cause several infections which...
In the subsequent wash steps, Gram-positive bacteria retain their purple colour; by comparison, the purple stain is removed from Gram-negative bacteria by the solvent, causing them to take up the colour of the counterstain. Examples of Gram-positive bacteria include Bacillus, Clostridia, Listeria,...

Figure 4. (a) In this gram-stained specimen, the violet rod-shaped cells forming chains are the gram-positive bacteriaBacillus cereus. The small, pink cells are the gram-negative bacteriaEscherichia coli. (b) In this culture, white colonies ofB. cereushave been grown on sheep blood agar. (...
Gram-negative bacteria have lesspeptidoglycan. The crystal violet gram stain colour is easily lost from ethanol-alcohol mix during decolorization. Because of this, they can be stained with the safranin dye (pink) after counterstaining. There are certainbacteriathat are not responding the same way ...
The meaning of GRAM-NEGATIVE is not holding the purple dye when stained by Gram's stain —used chiefly of bacteria.
Learn about Gram positive vs Gram negative bacteria. Discover the differences between Gram positive and Gram negative bacteria, and study examples...
The meaning of GRAM'S STAIN is a method for the differential staining of bacteria by treatment with a watery solution of iodine and the iodide of potassium after staining with a triphenylmethane dye (such as crystal violet) —called also Gram's method.
Based on the results of gram staining and on the morphology of the cells as seen through the microscope, gram-positive bacteria may be grouped as either gram-positive cocci or gram-positive bacilli. Gram-positive cocci are gram-positive bacteria that appear spherical. Examples includeStreptococcussp...
Compared to Gram negative bacteria, these bacteria are do not retain the primary stain and thus appear red when viewed under the microscope. Some examples of Gram negative bacteria include:· Gram negative cocci - Some of the most common Gram negative cocci bacteria include members of the genus...
