A Gram-negative bacteria is the one that does not retain crystal violet dye in the Gram staining protocol whereas a Gram-positive bacteria is the one that retains a crystal violet dye during the Gram stain process. HIV Virus can be caused by both these bacteria.

The answer from Aicha is correct except for the last sentence, which is completely false. "Gram" stains for peptidoglycan, a structure found in BACTERIAL cell membranes. Gram-positive bacteria (e.g. Staphylococcus aureus) have an abundance of peptidoglycan but Gram-negative bacteria (e.g. Pseudomonas aeruginosa) have much less. HIV is a virus, not a bacterium, so can't be Gram-stained as it has no peptidoglycan. Therefore, HIV is neither Gram-pos or neg.
Firstly HIV is a virus. Viruses do not stain gram positive or negative to a gram stain. Plus they are way too small to be seen under a normal microscope. Its bacteria that stain negative or positive to a gram stain with a very few exceptions and no HIV is a virus not a bacteria. HIV= Human immunodeficiency virus
