What is the value of gram staining?
Gram staining is highly valuable. It allows us to identify two widely different bacteria. Gram staining can tell you if the bacteria is pathogenic or if a penicillin pill can cure it. It tells us gram-positive bacteria, or gram-negative. Positive being easily combated bacteria and some even helpful, and gram-negative being primarily pathogenic.
What is the gram stain results for an L. lactus bacteria?
Lactococcus Lactus is a gram positive bacteria and therefore retains the darker staining and therefore shows on a gram stain as dark blue/violet colour. This is because the thick peptidoglycan cell wall retains the primary crystal violet stain.
Is the gram of influenza negative or positive?
(sign) Glucose is a carbohydrate (or sugar). Gram positive or negative refers to a bacterial cell wall and whether or not they take up certain stains. Glucose will be neither since glucose is a molecule and not a bacterial cell.
What charge results when specific elements become an ion?
Either it loose electron or gain and if loose then it get positive charge and if gain then be negatively charged ion
Why is it important to follow the gram staining procedure?
This is simply important in order to have accurate staining results. If this is not followed, the process of the staining will result to false positives or false negatives.

What is Gram staining method used for?
the purpose is to determine diffrent kinds of bacteria based on their results. if it'sgram positive the color will be pink and if it is gram negative the color will be red.

Finctions of alcohol in gram staining?
alcohol is organic solvent , it dissolves lipid in cell wall of Gram negative bacteria . this allows out flow of C.V. and counter staining by safranine which results in red color of Gram negative bacteria .
What are four possible results of a gram stain?
The four possible results after Gram staining are Gram positive, Gram negative, Gram variable and Gram in-determinant.
Is the gram of influenza negative or positive?
(sign) Glucose is a carbohydrate (or sugar). Gram positive or negative refers to a bacterial cell wall and whether or not they take up certain stains. Glucose will be neither since glucose is a molecule and not a bacterial cell.
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).
How does malaria stain for gram and endospore and capsule and acid fast?
Gram staining protozoans yield variable results. Endospore, capsule, and AF stains will yield different results, as these stains are use on bacteria. Malaria is caused by a protozoan.
What charge results when specific elements become an ion?
Either it loose electron or gain and if loose then it get positive charge and if gain then be negatively charged ion
Does a micrococcus luteus is positive for capsule stain?
yes as it have capsule it give positive test for capsule staining when stain with malachite green The problem with the above answer is that a capsule stain is NOT done with malachite green.
Why is it important to follow the gram staining procedure?
This is simply important in order to have accurate staining results. If this is not followed, the process of the staining will result to false positives or false negatives.
What is the importance of gram staining?
Gram staining (or Gram's method) is an empirical method of differentiating bacterial species into two large groups (Gram-positive and Gram-negative) based on the chemical and physical properties of their cell walls. It is a first step to determine the identity of a particular bacterial sample. Gram stains are performed on body fluid or biopsy when infection is suspected. It yields results much more quickly than culture, and is especially important when infection would make an important difference in the patient's treatment and prognosis.
