Multiple opportunistic infections are characteristic of the acquired immunodeficiency syndrome (AIDS). Although bacterial pathogens have presented few problems, we have noted an emerging problem with salmonellal infection among patients with AIDS. A review of all stool and blood cultures from adults between January 1982 and July 1984 showed that 80 stool cultures were positive for Salmonella species; serogroup B was the most common isolated. Eight (10%) were isolated from patients with AIDS. Nineteen blood cultures were positive for Salmonella species. Six (32%) were isolated from patients with AIDS: three were positive for Salmonella serogroup B; two yielded Salmonella choleraesuis; and one yielded Salmonella serogroup D. In three (50%), Salmonella bacteremia was a presenting manifestation of AIDS. Bacteremias were recurrent in five patients. Thus, it appears that AIDS not only predisposes patients to serious salmonellal infections but also compromises their ability to eradicate these bacteria.
