“…have been reported to co-aggregate with early biofilm colonizers such as Streptococcus sp. (Bolstad et al, 1996) having a special role as bridging organisms (Kolenbrander et al, 2002) allowing other bacteria to attach to biofilms. Whether F. nucleatum plays a similar role in biliary stent biofilms remains to be elucidated.…”

This study provides a comprehensive survey of the spatial and temporal bacterial composition of biliary stent biofilms. The bacterial diversity, distribution and dynamics of 59 biliary and 4 pancreatic stent communities from 40 patients being treated at two different hospitals, which implant stents either simultaneously or consecutively, were characterized by single-strand conformation polymorphism (SSCP) analysis. Fifty-one phylotypes belonging to 5 bacterial phyla and 24 bacterial families were detected across 63 stents. This is a much broader diversity than previously detected through culture-dependent methods, particularly in regard to the diversity of obligate anaerobes. Stent bacterial diversity was patient-dependent and more similar when stents were implanted simultaneously rather than consecutively. Stent bacterial community composition differed between hospitals specifically because of the difference in abundance of Bifidobacteria. Co-colonization of Veillonella sp., Streptococcus anginosus and organisms closely related to Fusobacterium nucleatum revealed a potentially important attachment and survival strategy that has yet to be reported in biliary stents. This work reveals a more complete survey of the identities of bacterial species that form biofilms in biliary stents, their co-colonization patterns and the natural variation in species composition between different patients, hospitals and locations along the stent. Consideration of the community composition from individual patients will allow tailoring of prophylactic antibiotic treatments and thus will make the management of stent biofilms more effective.

“…When one species predominates, it may exclude others and create new conditions for the remaining microorganims. Thus, in the oral biofilm multiple species can co-aggregate to colonize the tooth surface (32) , or provide nutrients to other bacteria by metabolization of substrates (33) . After cleaning the teeth, streptococci compete for colonizing saliva-coated enamel or dentin (34) , in some cases mediated by the expression of adhesion molecules (30) or antibacterial molecules (2,12) .…”

Background: Streptococcus mutans (S. mutans) is associated with the onset of caries. Since root exposure in patients affected by periodontitis leads to higher caries rates, progressively more severe forms of periodontal disease might associate with elevated counts of S. mutans. Aim: To determine whether increasingly destructive forms of periodontal disease are associated with higher counts of S. mutans in untreated patients. Methods: 206 subjects aged 20-75 were classified into three groups according to the severity of periodontal disease: 1) gingivitis, 2) chronic slight periodontitis and 3) chronic moderate or chronic severe periodontitis. S. mutans counts (cfu/mL) were obtained by direct counting on selective agar plates from saliva samples. A cumulative proportional logistic regression model was adjusted for S. mutans counts. Results: The model failed to show differences by gender, but periodontal diagnosis had a significant effect on S. mutans counts depending on age. While in the group with moderate and severe periodontitis the probability of having high counts of S. mutans significantly increased with age, the probability remained unchanged in individuals with chronic slight periodontitis or gingivitis. Conclusion: High S. mutans levels appear directly co-associated with increased severity of periodontal disease at older ages in untreated patients.

Antibacterial Properties of hLf1–11 Peptide onto Titanium Surfaces: A Comparison Study Between Silanization and Surface Initiated Polymerization

et al. 2015

Dental implant failure can be associated to infections which develop into periimplantitis. In order to reduce biofilm formation, several strategies focusing on the use of antimicrobial peptides (AMP) have been studied. To covalently immobilize these molecules onto metallic substrates several techniques have been developed, including silanization and polymer brush prepared by surface-initiated atom transfer radical polymerization (ATRP), with varied peptide binding yield and antibacterial performance. The aim of the present study was to compare the efficiency of these methods to immobilize the lactoferrin-derived hLf1-11 antibacterial peptide onto titanium, and evaluate their antibacterial activity in vitro.Smooth titanium samples were coated with hLf1-11 peptide under three different conditions: silanization with APTES, and polymer brush based coatings with two different silanes. Peptide presence was determined by X-ray photoelectron spectroscopy and the mechanical stability of the coatings was studied under ultrasonication. The LDH assays confirmed that HFFs viability and proliferation were no affected by the treatments. The in vitro antibacterial properties of the modified surfaces were tested with two oral strains (Streptococcus sanguinis and Lactobacillus salivarius) showing an outstanding reduction. A higher decrease in bacterial attachment was noticed when samples were modified by ATRP methods compared to silanization. This effect is likely due to the capacity to immobilize more peptide on the surfaces using polymer brushes and the non-fouling nature of polymer PDMA segment.3
