“…The occurrence of yeasts and enterobacteria associated to periodontal diseases in HIV-patients (Table 2) is in accordance with Moore et al (12). However, Dios et al (7) isolated yeasts and enterobacteria in 68% of the oral smooth mucosa.…”

The purpose of this study was to determine the prevalence of enteric bacteria and yeasts in biofilm of 80 HIV-positive patients with plaque-associated gingivitis or necrotizing periodontitis. Patients were subjected to extra, intra oral and radiographic examinations. The oral hygiene, bleeding on probing, gingival conditions, and attachment loss were evaluated. Clinical specimens were collected from gingival crevices or periodontal pockets, transferred to VMGA III, diluted and transferred to Sabouraud Dextrose agar with 100 μg/ml of chloramphenicol, peptone water, EVA broth, EMB agar, SS agar, Bile esculin agar and Brilliant green agar. Isolation of yeasts was carried out at room temperature, for 3-7 days; and for the isolation of enteric microorganisms plates were incubated at 37ºC, for 24-48 h. The yeasts identification was performed according to the carbon and nitrogen assimilation, fermentation of carbohydrates and germ tube formation. Bacteria were identified according to their colonial and cellular morphologies and biochemical tests. Yeasts were identified as Candida albicans and its occurrence was more common in patients with CD4+ below 200/mm 3 and was affected by the extension of periodontal involvement (P = 0.0345). Enteric bacteria recovered from clinical specimens were identified as Enterobacter sakazakii, Enterobacter cloacae, Serratia liquefaciens, Klebsiella oxytoca and Enterococcus sp. Enterobacteriaceae and enterococci were detected in 32.5% of clinical samples from patients with necrotizing periodontitis. In conclusion, non-oral pathogenic bacteria and C. albicans were more prevalent in periodontal sites of HIV-positive patients with necrotizing periodontitis and chronic gingivitis.

“…Gamella, Bacteroides, Streptococcus, and Veillonella mainly comprised these communities. Moore et al [43] also discovered higher numbers of Leptospira and mycoplasma in subgingival f lora of HIV-positive patients than those of HIV-negative individuals. These studies showed that subgingival f lora in HIV-positive patients with specificity may harbor unknown specific microorganisms or microbial species that were previously thought to be incapable of causing periodontal infection.…”

Significant progress was observed in studies of the relationship between oral Helicobacter pylori and gastric cancer and tumors. Based on three distinct and close relationships, namely, the relationship between oral H. pylori and gastric cancer, between oral microbial communities and oral squamous cell carcinoma, and between oral microbial communities of human immunodeficiency virus-infected patients and tumors, this work reviews the relationship between oral microbial communities and tumors. This research also provides reference for further analysis of the relationship between oral microorganisms and tumors to realize early diagnosis of tumor patients through detecting oral microorganisms under adjuvant therapy.

Fusobacterium nucleatum is indigenous of the human oral cavity and has been involved in different infectious processes. The production of bacteriocin-like substances may be important in regulation of bacterial microbiota in oral cavity. The ability to produce bacteriocin-like substances by 80 oral F. nucleatum isolates obtained from periodontal patients, healthy individuals and Cebus apella monkeys, was examinated. 17.5% of all tested isolates showed auto-antagonism and 78.8% iso-or hetero-antagonism. No isolate from monkey was capable to produce auto-inhibition. In this study, the antagonistic substances production was variable in all tested isolates. Most of the F. nucleatum showed antagonistic activity against tested reference strains. These data suggest a possible participation of these substances on the oral microbial ecology in humans and animals. However, the role of bacteriocins in regulating dental plaque microbiota in vivo is discussed.
