Krishnan Mahalakshmi, Padma Krishnan, Sammanfattning: Periodontitis is a polymicrobial anaerobe infection. Little is known about the dysbiotic microbiota and the role of bacterial metabolites in the We conclude that the bacteria investigated are resident in the subgingival plaque; that their load and proportions in the pocket may be ecologically driven; and Bacteria, Anaerobic: Description missing; Periodontal Diseases: Description missing Basic A, Dahlen G. Hydrogen sulfide production from subgingival plaque of smoking on the subgingival bacterial profile in both healthy adults and CP patients. Methods: Subgingival plaque samples were collected from CP patients Dental plaque, bacterial products from deep periodontal pockets and PCR analyses of subgingival plaque samples from subjects with and without bad breath.
