I don't believe that G. lamblia is either one. That is it cannot be identified via gram staining. A trichrome stain is needed to identify this bacteria. The trichome stain, originally a system of three colored dyes, illuminates the nuclei in the parasite and along with it's unique shape (that of a tear drop with two nuclei) identifies the parasite as giardia.

What value is the gram stain?
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.
How can you differentiate gram positive and gram negative bacteria?
The process of gram staining is simple. 1)smear bacteria from pure culture onto slide, heat fix 2)flood with crystal violet (1min) 3)Add iodine (1 min) 4)acid/alcohol wash (1 min) 5)Flood with safranine (1min) 6)Air dry and examine. These times are for clinical microbiology and experimental methods employ optimal and more precise times (but overall its pretty close). Down side of this method is that you must smear bacteria onto the slide and fix it by heating the underside of the slide with a bunsen burner. if they are pink then you have gram negative (Gram's stain didnt stick) if its purple then its gram positive(Gram's stain did stick) This is due to the peptidoglycan layers. Gram negative bacteria have only a thin layer of peptidoglycan as part of the cell membrane/wall where Gram positive have a very think peptidoglycan layer. Source(s): Medical Microbiology

Can you tell an organisms gram stain by simple staining?
Gram stain is not a simple stain because simple stains do not use two or more stains. Gram stain is a differential stain differentiating between Gram positive (blue-black) and Gram negative (pink-red).
How can you tell which is positive and which is negative by numbers?
the number that has the minus sign in front of it is negative and the normal number is positive example: negative: -9 positive: 9
Why do physician perform a gram stain on a sample before prescribing an antibiotic?
In order to know whose the best antibiotic to be prescribed. There are some antibiotics that are specific of a gram type (they won't be useful on both types), while there are other antibiotics that have a greater effect on a specific Gram type than on the other one.
How can you tell what side is negative and what side is positive?
Large side is negative
How do you know positive and negative terminals?
Look for a + by the positive terminal and a - by the negative terminal, or red for positive, black for negative. Some batteries have the positive terminal protruding and the negative terminal flat. Or you can get a meter that will tell you which is which,
How can you tell about two integers when their quotient is positive negative zero?
If both integers are positive or both negative then the quotient is positive. If they are one of each then the quotient is negative.
How can you tell if an electroscopic is negative or positive?
if it repells its negitive if it attracts its positive
A method called Gram staining is used to tell what?
Gram staining is primarily used to differential bacteria based on their cell wall structure. Bacteria are usually classified as Gram positive or Gram negative. Gram positive - thick layer of peptidoglycan as outermost layer, plasma membrane as innermost layer. Gram negative - thin layer of peptidoglycan "sandwiched" in between 2 separate plasma membranes.
How do you tell if a car has a negative or positive system?
Post the year, make and model of the vehicle (in new question) and one of us can tell you if it is negative or positive ground.
