 AB    Several trends in clinical medicine have converged recently and placed
       intestinal protozoan infections in a position of increasing importance
       to health professionals. These trends include the pandemic of human
       immunodeficiency virus (HIV) infections that cause the acquired
       immunodeficiency syndrome (AIDS) and result in associated opportunistic
       infections. The increasing use of powerful chemotherapeutic and
       immunosuppressive agents to prevent rejection of transplanted tissues in
       human allograft recipients has predisposed these patients to intestinal
       parasitic infections, which often become chronic and debilitating. Large
       numbers of people engage in business, philanthropic work, and vacation
       travel on a worldwide basis. The number of susceptible, potential human
       hosts for parasitic infections will continue to increase in the coming
       years. We reviewed 4 protozoan infections that have recently attracted
       the interest of clinicians, either because they are newly discovered or
       because they are increasingly prevalent. These infections include
       cryptosporidiosis and recently described infections due to Cyclospora
       species. The AIDS pandemic has also been associated with both the
       discovery and the rapid emergence of human microsporidiosis. Isospora
       belli has received renewed attention because of chronic infections now
       observed in HIV-infected hosts.
