Table 2. Prevalence of Antibiotic Resistance Genes (ARGs) stratified by periodontal health status (n = 110).
| ARGs | Healthy periodontium | Periodontal disease | All patients | |
|---|---|---|---|---|
| n (%) | n (%) | n (%) | ||
| 25 (22.7) | 85 (77.3) | 110 (100) | ||
| Gingivitis | Chronic periodontitis | |||
| n (%) | n (%) | |||

| erm | 15 (60.0) | 35 (57.4) | 14 (58.3) | 64 (58.2) |
| blaTEM | 2 (8.0) | 13 (21.3) | 3 (12.5) | 18 (16.4) |

| mecA | 0 (0.0) | 0 (0.0) | 3(12.5) | 3 (2.7) |
Of the 110 samples recovered, 80 (72.7%) were positive for at least one of the tested genes. In 9 cases two resistance genes were found in the same sample. Overall, 89 ARGs were detect.
