Near–infrared photodynamic inactivation of S. pneumoniae and its interaction with RAW 264.7 macrophages
(2018-01-01)
Pneumonia is the main cause of children mortality worldwide, and its major treatment obstacle stems from the microorganisms increasing development of resistance to several antibiotics. Photodynamic therapy has been presenting, ...
Chitosan enhances the antimicrobial photodynamic inactivation mediated by Photoditazine® against Streptococcus mutans
(2020-12-01)
Chitosan (CS), a biopolymer with intrinsic antimicrobial activity, can increase antimicrobial photodynamic inactivation (aPDI). The aim of this study was to evaluate the capacity of CS to potentiate the efficacy of ...
Biofilms of Candida albicans and Streptococcus sanguinis and their susceptibility to antimicrobial effects of photodynamic inactivation
(2018-12-01)
This study evaluated the effects of photodynamic inactivation (PDI) on single and multi-species biofilms, compounds by Candida albicans and Streptococcus sanguinis. Biofilms were formed, on microplate of 96 wells, by ...
Photodynamic inactivation for in vitro decontamination of Staphylococcus aureus in whole blood
(Elsevier B.V., 2019-12-01)
Background: Blood can be the target of microbial cells in the human body. Erythrocytes, platelets, and plasma concentrates in blood bags used in hemotherapy for blood transfusion are contamination targets, which can trigger ...
Photodynamic inactivation of microorganisms which cause pulmonary diseases with infrared light: an in vitro study
(International Society for Optical Engineering - SPIEBellingham, 2014)
Lower respiratory infections are among the leading causes of death worldwide. In this study, it was evaluated the interaction of indocyanine green, a photosensitizer activated by infrared light, with alveolar macrophages ...
Fast elimination of onychomycosis by hematoporphyrin derivative-photodynamic therapy
(Elsevier BVAmsterdam, 2013-09)
Onychomycosis is a fungal nail disease and is one of the major onychopathy worldwide. Topical or oral antifungal therapies are used to treat this disease, but often they are inefficient and oral medications can even cause ...
Photodynamic Therapy for Pododermatitis in Penguins
(Wiley-Blackwell, 2014-07-01)
Pododermatitis is currently one of most frequent and important clinical complications in seabirds kept in captivity or in rehabilitation centers. In this study, five Magellanic penguins with previous pododermatitis lesions ...
Comparison of the effect of rose bengal- and eosin Y-mediated photodynamic inactivation on planktonic cells and biofilms of Candida albicans
(2013-09-09)
Candida albicans is an opportunistic yeast that can cause oral candidosis through the formation of a biofilm, an important virulence factor that compromises the action of antifungal agents. The objective of this study was ...
Evaluation of gene expression SAP5, LIP9, and PLB2 of candida albicans biofilms after photodynamic inactivation
(Springer, 2015-07-01)
With the increasing number of strains of Candida ssp. resistant to antifungal agents, the accomplishment of researches that evaluate the effects of new therapeutic methods, like photodynamic inactivation (PDI), becomes ...
Photodynamic inactivation of virulence factors of Candida strains isolated from patients with denture stomatitis
(Elsevier B. V., 2015-09-01)
Candida species are major microorganisms isolated in denture stomatitis (DS), an inflammatory process of the mucosa underlying removable dental prostheses, and express a variety of virulence factors that can increase their ...
