Bactericidal effects of toluidine blue-mediated photodynamic action on Vibrio vulnificus.

Effect of Photodynamic Therapy Using Toluidine Blue on Eikenella corrodens and Aggregatibacter actinomycetemcomitans Biofilms Adhered to Titanium Discs: An In Vitro Study

Background and aim: Antimicrobial photodynamic therapy (aPDT) has been suggested as a novel technique for decontamination of exposed implant surfaces. We aimed to evaluate the effect of aPDT on sandblasted, large-grit, acid-etched (SLA) titanium discs contaminated with Eikenella corrodens (Ec) and Aggregatibacter actinomycetemcomitans (Aa). Materials and methods: In this in-vitro study, twenty...

Emergence of bactericidal and opsonizing antibody to Vibrio vulnificus following bacterial infection.

Virulent isolates of Vibrio vulnificus resist the bactericidal and opsonizing effects of normal human serum, in contrast to environmental isolates, which are highly serum susceptible. Immune responses to bacteremic V. vulnificus infections in human subjects have not been characterized. Serum from a patient who survived sepsis caused by V. vulnificus had substantial bactericidal and opsonizing i...

Photodynamic inactivation effect of methylene blue and toluidine blue O on ATCC Escherichia coli and clinical isolate of multidrug-resistant Escherichia coli

Antifungal effects of low level laser on Candida species with using Methylene blue and toluidine blue dayes

Introduction: Oral Candidiasis is the most common lesion in Immuno compromised patients. Using antifungal drugs are routine treatment for this condition. The aim of this study was incorporating photodynamic therapy with low level laser (685 nm), in presence of 2 dyes (methylene blue and tolidine blue), as a photosensitizer on C. albilcans, C. glabrata. C. krusie and C.tropicalis. Methods...

Toluidine blue-mediated photodynamic effects on staphylococcal biofilms.

Staphylococci are important causes of nosocomial and medical-device-related infections. Their virulence is attributed to the elaboration of biofilms that protect the organisms from immune system clearance and to increased resistance to phagocytosis and antibiotics. Photodynamic treatment (PDT) has been proposed as an alternative approach for the inactivation of bacteria in biofilms. In this stu...
