Is Giardia Lamblia gram positive or gram negative?

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.
