“…Concerning all tested antibiotic resistance genes, it was observed a total of 42% of antibiotic resistance genes in strains isolated from periodontal infections (Table 1). These results agree with most studies of other countries that show high levels of antibiotic resistance among anaerobes [12,[15][16][17][18].…”

Objective: Porphyromonas gingivalis and Prevotella intermedia are thought to be pathogens in adult periodontitis. Antibiotherapy is usually needed in the treatment of periodontitis being often prescribed empirically. To allow prescription of a specific antibiotic treatment, identification of resistance genes should be performed. The aim of this study was the identification of the presence of TetM, TetQ, TEM, cfxA, MefA, ErmB and Nim resistance genes in previously identified P. intermedia and P. gingivalis isolated from samples collected from periodontal infections.Method: PCR was used for the identification of TetM, TetQ, TEM, cfxA, MefA, ErmB and Nim resistance genes in strains isolated from samples collected from periodontal infections.Results: It was seen that 8% of isolates had one of the tested tetracycline resistance genes. A total of 32% of β-lactamases resistance genes was observed in isolated strains. It was also observed that 2% of isolates had one of the analysed erythromycin resistance genes. None of the isolates showed the presence of the metronidazole resistance gene. Conclusions:Most strains harboring β-lactamase resistance genes had been previously identified as P. intermedia. No tetracycline resistance gene and a very low percentage of β-lactamase resistance genes were observed in P. gingivalis strains.

“…Several investigators have reported β‐lactamase production in periodontal isolates of Prevotella spp. (3, 6–8, 13, 15, 18, 29, 30). Significant resistance has also been detected in other periodontal pathogens, such as Fusobacterium spp., Capnocytophaga spp., and in oral superinfecting Enterobacteriaceae and staphylococci (9, 10, 13, 16, 20, 21, 25).…”

This study assessed the extent of beta-lactamase-producing bacteria in subgingival plaque samples obtained from 25 patients with refractory marginal periodontitis in the USA. beta-Lactamase-positive isolates were characterized using commercial diagnostic kits and partial sequencing of the 16S rRNA gene. The susceptibilities to different antimicrobial agents were tested and, in addition, the isolates were screened for the presence of extended spectrum beta-lactamases (ESBLs). beta-lactamase-producing bacteria were detected in 18 (72%) patients. The most prominent beta-lactamase-producing organisms belonged to the anaerobic genus Prevotella. Other enzyme-producing anaerobic strains were Fusobacterium nucleatum, Propionibacterium acnes and Peptostreptococcus sp. Facultative bacteria, such as Burkholderia spp., Ralstonia pickettii, Capnocytophaga spp., Bacillus spp., Staphylococcus spp. and Neisseria sp., were also detected among the enzyme-producers. Minimum inhibitory concentrations (MICs) of ampicillin and amoxicillin were in the range 1.5-256 micrograms/ml and 4-256 micrograms/ml, respectively, for the isolates of the Prevotella species. All Prevotella isolates were susceptible to amoxicillin/clavulanate and metronidazole, but they showed variable resistance to tetracyclines. Two of the Prevotella isolates had high MICs of cefotaxime and ceftazidime. ESBL activity was not detected in any of the beta-lactamase-producing isolates by the Etest method. Thus, our study demonstrated a wide variety of beta-lactamase-producing bacteria that may play a role in refractory periodontal disease.

“…Prevotella bivia, P. disiens and the pigmented Prevotella species elaborate frequently such inactivating enzymes, especially penicilinases [35,36] and sometimes also cephalosporinases [29]. The rates of positive beta-lactamase Prevotella strains reported in the literature are widely different.…”
