[New bacterial infections in the course of AIDS].

The authors reviewed the recent data on unusual or newly described bacterial infection in AIDS. Mycoplasma species are frequently associated with AIDS and hypothesized to play as a cofactor in AIDS evolution (Mycoplasma fermentans and Mycoplasma penetrans). Rochalimea henselea and Rochalimea quintana are the agents of peliosis and bacillary angiomatosis. Some Mycobacterium and Campylobacter species, not previously considered as human pathogens, have been recently involved in severe infection in patients with AIDS.
