The microbiologic flora of orofacial abscesses

Effects of propicillin on mixed continuous cultures of periodontal bacteria

“…Slow growth rate and restricted availability of nutrients in the natural environment may be major contributors to phenotypic changes leading to the relative insusceptibility to drugs in vivo (2,3,20,23). This may not explain the fact that in the treatment of orofacial abscesses, a good response to antibiotic therapy may follow even when resistant pathogenic species are present (8). Possible explanations for this latter phenomenon include the disturbance of synergistic growth of the mixed microbiota in the abscess by the antibiotic.…”

Further characterization of Bacteroides endodontalis, an asaccharolytic black-pigmented Bacteroides species from the oral S cavity

“…Within this group of microorganisms, black-pigmented Bacteroides bacteria play an important role (13,17,24). This is true not only for periodontal diseases but also for infections of dental pulp tissues (5), periodontitis apicalis (18), and orofacial abscesses (1,7). The significance of black-pigmented Bacteroides species in these infections has been reviewed recently (15).…”

Degree of Contamination of Gutta-Percha Points by Staphylococcus aureus (MRSA/MSSA) Strains

“…Over the years, S. aureus has been correlated with several non-physiological oral conditions, such as acute suppurative parotitis [ 5 , 6 ], angular cheilitis [ 7 ], and staphylococcal mucositis [ 8 , 9 ]. This bacterium has also been detected in oral infections such as jaw cysts [ 10 ] and orofacial abscesses [ 11 , 12 , 13 ].…”
