Abstract
Aspiration of oral bacteria leads to cardiac and respiratory infectious diseases and dentures can act as a reservoir for pathogenic microorganisms.
To determine the occurrence and the
Denture biofilm was collected and samples plated on MacConkey agar. The isolated bacterial colonies were identified using the BBL Crystal enteric/non-fermenter system. Antibiotic bacterial susceptibility was assessed by the disc diffusion method of amoxicillin, amoxicillin/clavulanic acid, doxycycline, tetracycline, tobramycin, imipenem, cefotaxime, and ciprofloxacin. The Minimum Inhibitory Concentration (MIC) of cefotaxime, tobramycin, doxycycline, imipenem, and ciprofloxacin was determined for 40 species by E-test.
34 subjects (65.4%) harbored enteric rods in their prostheses.
The findings show high prevalence of nosocomial diseases-related bacterial species and low susceptibility to antimicrobial drugs. Therefore, these results imply caution against the indiscriminate use of broad spectrum antibiotics in dental practice.

The isolated bacterial colonies were identified using the BBL Crystal enteric/non-fermenter system. Antibiotic bacterial susceptibility was assessed by the disc diffusion method of amoxicillin, amoxicillin/clavulanic acid, doxycycline, tetracycline, tobramycin, imipenem, cefotaxime, and ciprofloxacin. The Minimum Inhibitory Concentration (MIC) of cefotaxime, tobramycin, doxycycline, imipenem, and ciprofloxacin was determined for 40 species by E-test.</p></sec><sec><title>Results:</title><p>34 subjects (65.4%) harbored enteric rods in their prostheses. <italic>Klebsiella pneumoniae</italic> (26.5%), <italic>Escherichia coli</italic> (23.5%), and <italic>Enterobacter aerogenes</italic> (23.5%) were the most prevalent species. All organisms were susceptible to ciprofloxacin and most species were resistant to amoxicillin or amoxicillin/clavulanic acid, demonstrating variable sensitivity patterns to other antimicrobials. However, the MIC showed the emergence of strains with reduced sensitivity to ciprofloxacin (MIC<sub>90</sub>≥3 μg/ mL) and cefotaxime (MIC<sub>90</sub>≥2 μg/mL).</p></sec><sec><title>Conclusion:</title><p>The findings show high prevalence of nosocomial diseases-related bacterial species and low susceptibility to antimicrobial drugs. Therefore, these results imply caution against the indiscriminate use of broad spectrum antibiotics in dental practice.</p></sec></abstract><kwd-group><title>Keywords:</title><kwd>Biofilms</kwd><kwd>Enterobacteriaceae</kwd><kwd>Pseudomonas</kwd><kwd>Drug resistance</kwd></kwd-group><counts><fig-count count="0"></fig-count><table-count count="7"></table-count><equation-count count="0"></equation-count><ref-count count="33"></ref-count><page-count count="10"></page-count></counts></article-meta></front></pmc></record>Pour manipuler ce document sous Unix (Dilib)
