a gram negative rod
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.
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.
No. Impetigo is usually caused by Staphylococcus aureus, gram positive cocci.
Gram positive organisms are either rods or cocci. Rods, or bacilli, include Bacillus anthracis, which causes anthrax, while cocci include Staphylococcus aureus.
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.
No, they are not. Conidium are fungi, they grow separately from baccili.
Corynebacterium is a non spore forming gram positive cocci
Spore forming, gram positive rods
Aminogylcosides
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.
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
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.
