BOTERO B, Alejandro et al. Evaluation of the therapeutic approach of various types of periodontal disease. Part III: enterobacteriaceae enteric rods, and yeast species. Rev Fac Odontol Univ Antioq [online]. 2008, vol.20, n.1, pp. 72-86. ISSN 0121-246X.
INTRODUCTION: (see parts I and II): this publication is focused on the prevalence of enteric rods and yeasts species in samples taken from subgingival plaque of 69 patients included in the investigation. Preliminary studies suggest an association between enteric rods and some types of periodontal pathogens. Microbiological analysis was realized by means of culture, and susceptibility was determined for the following antibiotics: Ciprofloxacin, Metronidazole, Amoxicillin, Tetracycline and Clindamycin. METHODS: evaluations of the socio-demographic criteria (age, gender, tobacco use, and family grouping), and clinical parameters (probing depth, clinical attachment, superficial bleeding, and probing bleeding) were made at the beginning, 3, 6, 12, and 24 months. Microbiological samples of each patient were taken from 6 different sites at the beginning of the study, 12, and 18 months. The results corresponding to the presence of enteric rods, and Candida albicans are only part of the first sample, which measured the prevalence, although all the patients had a follow up of two years after conventional non surgical periodontal therapy. A descriptive analysis was made, which determined the frequency, proportion, and prevalence of enteric rods and yeasts in both groups, good and poor responders, shown in frequency distribution tables and compound bar charts. RESULTS: the most prevalent species, found in subgingival microflora in patients with periodontitis n=69(36.2%) including both, good n=57 (33.3%) and poor responders n=12 (49.9%) were enteric rods, mainly Escherichia coli, Klebsiella spp and Enterobacter spp, and yeasts. CONCLUSION: Escherichia coli had the highest prevalence percentage in both, good and poor responders. According to antimicrobial susceptibility test, Ciprofloxacin would be the antibiotic of choice in subjects with periodontitis and with enteric rods.
