In vitro lethal photosensitization of S. mutans using methylene blue and toluidine blue O as photosensitizers.
The purpose of this in vitro study was to evaluate the antimicrobial effect of photodynamic therapy on Streptococcus mutans (A TCC 25175) suspensions, using a red laser for one minute in combination with toluidine blue O (TBO) or methylene blue (MB). Both photosensitizers were used in three concentrations (25, 10 and 5 mg/L). The activity ofphotosensitizers and laser irradiation were tested sep...
متن کاملPhotosensitization of T2 coliphage with toluidine blue.
The photodynamic action of dyes upon biological systems has been reviewed by Blum (1941). Inactivation of bacteriophage by this process has been studied by Clifton (1931), Perdrau and Todd (1933), Burnet (1933), Morales (1941), and Pacheco and Morales (1941). More recently, Welsh and Adams (1954) and Yamamoto (1956, 1958) investigated the kinetics of photodynamic inactivation of coliphage. In t...
متن کاملIn vivo killing of Porphyromonas gingivalis by toluidine blue-mediated photosensitization in an animal model.
Porphyromonas gingivalis is one of the major causative organisms of periodontitis and has been shown to be susceptible to toluidine blue-mediated photosensitization in vitro. The aims of the present study were to determine whether this technique could be used to kill the organism in the oral cavities of rats and whether this would result in a reduction in the alveolar bone loss characteristic o...
متن کاملThe Susceptibility Evaluation of Multiresistant Gram-Negative Bacilli to Meropenem and Imipenem
Introduction: Nosocomial infections are responsible for the much of the morbidity and mortality found in hospitals. The present study was conducted on 70 bacterial strains isolated from hospitalized patients in various medical units of Baqiyatallah Hospital in Tehran, Iran during a period of 12 months from; March to February 2009. Methods: The bacterial s...
متن کاملEfflux-mediated resistance to fluoroquinolones in gram-negative bacteria.
The introduction of the fluoroquinolones (FQs) in the 1980s provided clinicians with a class of broad-spectrum agents applicable to a range of gram-negative infections including urinary tract infections, gastrointestinal infections, respiratory tract infections, sexually transmitted diseases, bone and joint infections, and infections of the skin and soft tissue (reviewed in references 10 and 43...
