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.
