Successful implementation of intestinal endoscopy in non-human primates prompts the possibility of achieving AIDS longitudinal intestinal research.

HIV infection induces pathological changes in the intestinal mucosa. Here, a successful endoscopy was performed on the colon of a Chinese rhesus macaque by using Olympus CV170 gastroscope. The stability on postoperative recovery and the integrity of biopsy tissue implied a possibility of achieving AIDS longitudinal intestinal research on macaques.
