Frequency of <i>Campylobacter rectus</i> throughout human lifespan
Abstract
The aim of this cross-sectional study was to verify the prevalence of Campylobacter rectus in dentate and edentulous subjects of different ages living on Vale do Paraíba. The study included forty newborns (2.20 ±1.30 months), forty children (9.33 ±1.99 years of age), thirty dentate adults and elderly subjects (61.7 ± 7.05 years of age) and thirty edentulous adults and elderly subjects (65.8 ± 6.69 years of age). Extra-sulcus samples (cheek mucosa and dorsum of the tongue) were obtained from all subjects. In addition, subgingival samples (sulci or periodontal pockets) were collected from dentate subjects. All samples were analyzed using a bacterial DNA-specific polymerase chain reaction. Bacterial frequencies were statistically analyzed using Chi-square tests. All studied groups presented with C. rectus, irrespective of the presence of the teeth (newborns 25.64%, children 92.50%, dentate adults and elderly 93.33%, edentulous adults and elderly 96.67%). There was a statistically difference between newborns’ samples and samples from all other groups for both extra-sulcus sites (p=0.001). The impact of the presence of teeth was confirmed on bucal microbiological colonizations. Therefore, it is important to make strategies to reduce periodontal pathogens, including C. rectus, to avoid the development of periodontal diseases.
