What is the difference between gram-positive cocci and gram-negative rods?
Gram-positive cocci are bacteria with a spherical shape that retain a purple stain in the Gram staining method, indicating a thick peptidoglycan cell wall. Gram-negative rods are bacteria with a rod shape that appear pink after Gram staining due to their thinner peptidoglycan cell wall and an outer membrane containing lipopolysaccharides. Additionally, gram-negative rods generally have higher resistance to antibiotics compared to gram-positive cocci.
Suppose you are viewing a Gram stained field of red rods and purple cocci through the microscope What do you conclude?
The rods will be gram negative, the cocci are gram positive: most likely, the slide was made from a mixed culture of bacteria, or the culture was contaminated.
Is impetigo gram positive rods?
No. Impetigo is usually caused by Staphylococcus aureus, gram positive cocci.
What is Gram positive rod cocci?
Gram positive organisms are either rods or cocci. Rods, or bacilli, include Bacillus anthracis, which causes anthrax, while cocci include Staphylococcus aureus.
What is the conclusion of a gram stain of purple rods and cocci through a microscope?
This is a Gram Stain. If the technique was proper, the red rods are Gram-negative and the purple cocci are Gram-positive. This staining technique is used to help identify various bacteria. The Gram-positive bacteria that are purple hold the stain due to it's layered cell membrane. It contains a peptidoglycan layer that acts as a lattice trapping the crystal violet-Iodine dye complex.
Are conidiospores found on gram positive cocci and rods?
No, they are not. Conidium are fungi, they grow separately from baccili.
Corynebacterium is a spore forming gram positive cocci?
Corynebacterium is a non spore forming gram positive cocci
Is botulism gram positive or gram negative?
Spore forming, gram positive rods
Gram negative rods are often treated with?
Aminogylcosides
You are viewing a Gram stained field if red rods and purple cocci through a microscope What do you conclude?
A gram stained field of red rods and purple cocci through a microscope may indicate a severe bacterial infection. The next step would be to do a culture of the bacteria to find the correct antibiotic needed to treat the infection.
What is the shape of the haemophilus influenza?
Haemophilus influenza is a small, pleomorphic, gram-negative coccobacillus, meaning it can appear as both cocci (spherical) or bacilli (rod-shaped) under the microscope. Its shape can vary from very short rods to more elongated forms.
What gram stain that purple cocci and pink rods means?
it is talking about different colors different types of bacterium turn when stained a certain color depending on cell wall/membrane thickness 'purple cocci' is referring to a round bacteria which in this case thick cell wall/membranes because of its darker color, 'pink rods' is referring to rod or stick-like bacteria which in this case have thin cell wall/membranes because of their color the darker the stain color is on the bacteria/cell/protist/etc. the thicker the wall/membrane is
