HIV is a virus and, therefore, is neither Gram positive nor Gram negative. The Gram stain is used to identify bacteria as either Gram negative or positive, depending upon the type of cell wall the bacteria has. The Gram stain cannot be used on viruses.
Gram-positive cells are purple and the Gram-negative cells are red.
Gram positive
Nostoc is a type of cyanobacteria that contains both gram-positive and gram-negative characteristics. It does not fit neatly into the gram-positive or gram-negative classification system due to its unique cell wall structure.
E. coli is Gram-negative.
gram positive
The answer to whether HIV gram-stain positive or negative is that HIV gram-stain is negative. They retain the light red or pink color after the stain.
HIV-positive means you are infected with the human immunodeficiency virus. HIV-negative means that you are not infected with the HIV.
It is better to be HIV negative than HIV positive. An HIV positive person is infected with HIV.

Gram-positive bacteria and Gram-negative bacteria are different in their colouration when dyed and viewed with a light microscope. Gram-positive appear violet, and Gram-negative appear red. Gram-positive and Gram-negative classification, however, has nothing to do with size.
