Is the acid fast stain result positive or negative for the sample?
The acid-fast stain result is positive for the sample.
Is the acid fast stain positive or negative in the sample?
The acid-fast stain is positive in the sample.
Which step is most crucial or most likely to cause poor results in the gram stain?
Gram staining is a type of differential staining in which two types of bacteria are differentiated on the basis of their cell wall either gram positive or gram negative although all the steps in gram staining are crucial, the most important step the most crucial step in the performance of the Gram staining procedure is the decolorization step which is the Acid-Alcohol (3% HCl and 95% Ethanol) and must be timed correctly; the crystal violet stain will be removed from both Gram-positive and negative cells if the decolorizing agent is left on too long (a matter of seconds).
Why are contrasting colors important in gram staining?
# Suppose you performed a gram stain on a sample from a pure culture of bacteria and observed a friend of red and purple cocci. Adjacent were not always the same color. What do you conclude? # ## The bacteria was not a pure culture.
What staining procedure will be used to observe bacteria in the sputum sample?
A Gram stain is commonly used to observe bacteria in a sputum sample. This staining procedure helps visualize the bacterial cell wall structure and arrangement, aiding in the identification of different bacterial species.
Is the acid fast stain result positive or negative for the sample?
The acid-fast stain result is positive for the sample.
What the precaution on negative stain?
One precaution when using negative staining is to ensure that the sample is completely dry before applying the stain. Any presence of water can affect the staining process and result in inaccurate visualization of the sample. Additionally, it is important to handle the stain carefully, as some negative stains can be toxic or corrosive.
Factor that would give False results in gram staining?
Several factors can lead to false results in Gram staining, including improper sample handling or storage, which may cause bacterial cell degradation. Inadequate fixation of the sample can result in the loss of bacteria during staining. Additionally, over-decolorization or under-decolorization can misclassify Gram-positive bacteria as Gram-negative or vice versa. Lastly, using old or expired reagents can also affect the staining outcome.
Biochemical test results for proteus vulgaris?
Biochemical tests commonly used to identify Proteus vulgaris include urease test (positive result), indole test (negative result), motility test (positive result), citrate test (negative result), and carbohydrate fermentation tests (positive results for lactose and sucrose, negative result for glucose). These tests together help in confirming the presence of Proteus vulgaris in a given sample.
Can the sample mean in statistics be either positive or negative?
It can have either a negative or positive trend
Is the acid fast stain positive or negative in the sample?
The acid-fast stain is positive in the sample.
Indication of a negative result with Bial's Reagent?
A negative result with Bial's reagent will show no color change, indicating the absence of pentoses in the test sample. This can be confirmed by the lack of a green color formation, which is characteristic of a positive result when pentoses are present.
Can o positive father and a positive mother have a negative child?
if your child is negative, i would ask for a blood sample from the mailman
Is biuret test positive or negative control?
The biuret test is primarily used to detect the presence of proteins in a sample. A positive control would be a solution known to contain proteins, which should yield a violet color when subjected to the test, indicating a positive result. A negative control, on the other hand, would be a solution without proteins, which should remain blue, indicating a negative result. Thus, the test can use both positive and negative controls for validation.
Can o positive father and o negative mother have A positive child?
if your child is negative, i would ask for a blood sample from the mailman
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.
Why you do staining?
Staining is done to help determine what the sample is. It makes it visible under a microscope and it gives some information about the structure of the cell. A positive Gram stain means that the cell has a thick peptidoglycan layer.
