[Antibiotic sensitivity of 32 strains of Stomatococcus mucilaginosus in oral medicine patients in community practice].

Susceptibility to eleven antibiotics of 32 strains of Stomatococcus mucilaginosus isolated from gingival or dental samples in patients who are nor hospitalized nor receiving antibiotics since six months was tested by diffusion and MIC. 12.5% of strains were resistant to macrolides and lincosamides. This result is significantly different from the result obtained with strains isolated from patients hospitalized for chronic pulmonary problems (36%). This resistance to antibiotics could be due to selection pressure as shown by the high incidence of resistant strains in antibiotic treated patients.
