- Abstract
The incidence and virulence of Staphylococcus aureus from upper dentures and tongues of maxillary resection and edentulous patients were examined. The incidence rates of S. aureus on dentures and tongues from the 8 maxillary resection patients were significantly higher than those from the 20 maxillary edentulous patients. Some S. aureus strains in both patient groups were resistant to antibiotics, and 1 methicillin-resistant S. aureus strain was isolated in each group. Exfoliative toxin was not produced, whereas diverse types of enterotoxin were detected in 4 of the 8 maxillary resection patients and in 3 of 13 maxillary edentulous patients. These findings show that S. aureus inhabits dentures and tongues of maxillary resection patients more often than those of maxillary edentulous patients and that some strains have potential virulence, suggesting that maxillary resection patients are potentially more exposed to a threat from S. aureus and would be the carriers.
