Clinical variables included probing pocket depth, clinical attachment level, plaque, bleeding on probing, and suppuration. The aim of this study was to compare the prevalence and levels of beta-lactamase producing bacteria in the subgingival microflora in adult patients with periodontitis in Spain and The Netherlands, and to characterise beta-lactamase antibiotics producing bacteria in both patient samples. Beta-lactamase producing bacteria were isolated and identified. A higher prevalence and a more complex beta-lactamase producing microflora, were found antibiotics in the Spanish group, associated with a higher antibiotic consumption. Bacterial colonies growing on amoxicillin plates but not on amoxicillin/clavulanate plates were tested for beta-lactamase production. This information may be important in the treatment of severe periodontitis.. Evaluation of previous antibiotic use revealed that, in the previous 12 months, 54.8% of patients in the Spanish group and 10% in the Dutch group reported antibiotic use (p<0.001). A high prevalence of beta-lactamase producing bacteria has been evaluated in two distinct populations, belonging to two European countries with clear differences in antibiotic usage policy. Total buy acyclovir counts of beta-lactamase producing pathogen on amoxicillin plates (p<0.01), the mean number of different beta-lactamase producing colonies per patient (p<0.001), and the number of amoxicillin resistant colonies (p<0.001) were significantly higher in the Spanish group. Current systemic disorders and medications, history of use of antibiotics, and smoking habits. Pooled subgingival samples of 4 selected sites were anaerobically cultured in blood agar plates with and without amoxicillin, and amoxicillin/clavulanate. Beta-lactamase producing bacteria in the subgingival microflora of adult patients with periodontitis. The prevalence of beta-lactamase producing bacteria was 87.1% in the Spanish group and 73.3% in the Dutch group. Patients with moderate to severe periodontitis were consecutively selected and asked to report on. Countries with a high per capita antibiotic use frequently demonstrate a high level of drug resistance. This study shows that a higher use of beta-lactam antibiotics is reflected in the % of beta-lactamase producing bacteria in the subgingival microflora of patients with periodontitis. 31 patients were studied in the Spanish group and 30 in the Dutch group. 74 beta-lactamase producing strains in the Spanish group and 33 in the Dutch group were isolated for identification. Comparable mean gender and ages were found. A comparison between Spain and The Netherlands.BACKGROUND/AIMS. 23 out of 35 identified strains in the Spanish group, and 32 out of 33 in the Dutch group belonged to Prevotella genus.
