BACTERIAL ENTERIC INFECTIONS IN PERSONS INFECTED WITH HUMAN-IMMUNODEFICIENCY-VIRUS

We review the epidemiology and prevention of and future research prior ities for bacterial enteric infections in persons infected with the hu man immunodeficiency virus (HIV). HIV-infected persons are more freque ntly infected with Salmonella, Campylobacter, Listeria, and (possibly) Shigella species than are individuals not infected with HIV. In addit ion, Salmonella and (possibly) Campylobacter infections are more likel y to be severe, recurrent, or persistent and associated with extrainte stinal disease when they occur in HIV-infected persons. Infections cau sed by Shigella and Vibrio species can also result in more serious dis ease in HIV-infected persons than in those not infected with HIV. Risk of these infections can be reduced with proper precautions, particula rly those pertaining to food hygiene, animal contact, and travel. Indi viduals infected with HIV should be informed of their increased risk o f acquiring these diseases and should be counseled on the recommended precautions.
