| Popis: | According to the American National Institutes of Health, about 80% of bacterial infections are film-associated that impedes their treatment and prevention. Scientists emphasize that the frequent chronicity of diseases associated with film-forming pathogens, and their significant resistance to antimicrobials today poses the major health problem worldwide. The aim of this study is to determine the film-forming properties of clinical isolates of Streptococcus spp. isolated from patients having odontogenic purulent-inflammatory diseases of the soft tissues of the maxillofacial area in the presence of antiseptics decasan and chlorhexidine. Materials and methods. The clinical isolates of S. warneri (n = 3), S. sanguinis (n = 4), S. sobrinus (n = 4), S. mitis (n = 4), S. salivarius (n = 5) were the objects of the study. To identify film-forming properties of the clinical isolates, a spectrophotometric method according to G.D. Christensen was applied. The antiseptics based on cationic surfactants as Decasan 0.2 (LLC "Yuri-Pharm", Kyiv, Ukraine) and chlorhexidine bigluconate 0.05 (Chlorhexidine-KR®, PJSC "Chimpharmzavod" Red Star ", Kharkiv, Ukraine) were used. Results and discussion. The study has shown that S. sorbinus and S. sanguinis have high film-forming properties; S. mitis and S. warneri demonstrate moderate film-forming properties. The antiseptic Decasan helped to reduce the film formation by all investigated isolates of Streptococcus spp. The effect of chlorhexidine on the ability of microbial isolates to produce biofilms was slightly lower compared to Decasan; moreover, in the case of S. mitis species, chlorhexidine even enhances film-forming properties. Conclusion. Streptococci of the viridans group, which are isolated from patients having odontogenic purulent-inflammatory diseases of the soft tissues of the maxillofacial area, have different film-forming properties. Decasan is more effective against the film formation by streptococci compared to Chlorhexidine. |
