The purpose of this study was to examine colonization by specific organisms at periodontal sites in HIV‐seropositive [HIV(+)] subjects. A total of 67 HIV(+) and 32 HIV(‐) subjects were investigated. The specific pathogens included black‐pigmented anaerobic rods (BPAR), Porphyromonas gingivalis, Actinobacillus actinomycetemcomitans, Candida albicans and mycoplasma species. P. gingivalis was present in the HIV(+) subjects more frequently than in the HIV(‐) periodontitis patients ( P < 0.01). The cell numbers of BPAR and P. gingivalis and percentages as the total of CFUs on blood agar cultured in an anaerobic chamber were statistically higher in periodontal pocket samples from HIV(+) than from HIV(‐). A. actinomycetemcomitans was also detected at a high rate (41.8%) in HIV(+) patients. The average cell numbers of C. albicans were higher in samples from the HIV(+) group ( P < 0.05). The detection rate of mycoplasma species in the HIV(+) patients was significantly lower than that in HIV(‐) subjects ( P < 0.05), and most isolated mycoplasma strains were Mycoplasma salivarium .
