Chlamydia pneumoniae and Mycoplasma pneumoniae: Opportunistic Infectious Agents in HIV/AIDS

Abstract

Abstract

The objecttive of this study was to investigate the prevalence of Chlamydia pneumoniae and Mycoplasma pneumoniae, c orrelated with AIDS patients. Ninety-seven c ases of HIV infection were d escribed. C. pneumoniae and M. pneumoniae infections were s erologically d iagnosed by microimmunofluorescence test us ing s tandard d iagnostic cr iteria and an agglutination test (SERODIAMYCOII), r espectively. The prevalence of antibodies to C. pneumoniae and M. pneumoniae was 87.6% (85/97) and 45.4% (44/97), r espectively. By age, the group aged 21-30 y ears had the highest r ates of infection with C. pneumoniae [44 (45.4%)] and M. pneumoniae [24 (24.7%)]. Injecting dru g us ers had the highest r ates of infection with C. pneumoniae [68 (70.1%)] and M. pneumoniae [39 (40.2%)]. C. pneumoniae su btype E was the most prevalent infectious agent [48 (49.5%)], f ollowed by M. pneumoniae [22 (22.7%)]. The r esults of this study indicated that C. pneumoniae may play a r ole in the etiology of respiratory -tract infections among HIV-positive patients.
