1. To compare the immunophenotyping of the gut mucosa to that of the peripheral blood in HIV negative and in non-acute HIV-infected subjects 2. To compare the immunophenotyping of the peripheral blood in HIV negative and non-acute HIV-infected adults to the findings from acutely HIV-infected subjects in the WRAIR#1494/RV254/ SEARCH 010 study 3. To compare immunologic markers in the genital compartment compared to the peripheral blood in HIV negative and non-acute HIV-infected adults to the findings from acutely HIV-infected subjects in the WRAIR#1494/RV254/ SEARCH 010 study 4. Archive samples for immunologic and virologic testing

Understand the study and sign informed consent form. Persons who cannot read will have the consent form read to them by a study staff and they can give informed consent by using thumb print.
Have gastrointestinal disorders or gastrointestinal symptoms that require endoscopy for diagnostic purposes or have systemic disorders, which include but may not be limited to autoimmune diseases such as rheumatoid arthritis, systemic lupus erythematosus or psoriasis, that in the judgment of investigators could cause colon mucosa to be abnormal on biopsy
