 AB    Human immunodeficiency virus (HIV)-associated intestinal abnormalities
       can occur before immunodeficiency or infection with opportunistic
       enteropathogens. Rhesus macaques infected with simian immunodeficiency
       virus (SIV) develop an AIDS-like illness that frequently includes
       enteropathy. The development of enteropathy and its association with SIV
       infection in the intestinal tract was examined. By 1 week after
       infection, SIV-infected macrophages and T lymphocytes were detected in
       gut-associated lymphoid tissue. In contrast to findings in the
       asymptomatic stage, SIV-infected macrophages were numerous in primary
       and terminal stages of infection. An acute enteropathy syndrome was
       observed in the primary acute stage of infection. Functional
       abnormalities of absorptive epithelium, indicated by D-xylose
       malabsorption and decreased sucrase activity, occurred before the onset
       of diarrhea or opportunistic enteric infections. These findings indicate
       that macrophages and T cells in the intestinal tract are early targets
       of SIV infection and may play a critical role in the development of
       SIV-associated intestinal dysfunction.
