A gram stain cannot detect chlamydia. A gram stain in men that finds gram negative diplococci is considered diagnostic for gonorrhea, but it can't be used in females, and it can't prove chlamydia. A gram stain in men can be used to rule out gonorrhea and possibly diagnose "non-gonococcal urethritis" if a male has symptoms. However, although it may seem that NGU is synonymous with chlamydia, there are other possible causes.
gram staining is a biochemical method of identifying bacteria in a more specific way.Thus it is important to differentiate gram positive and gram negative bacteria.

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.
