The Caliciviridae family of viruses contains clinically important human and animal pathogens, as well as vesivirus 2117, a known contaminant of biopharmaceutical manufacturing processes employing Chinese hamster cells. An extensive literature exists for inactivation of various animal caliciviruses, especially feline calicivirus and murine norovirus. The caliciviruses are susceptible to wet heat...
Surfaces can be coated with photosensitizer molecules, which generate singlet oxygen ((1)O2) when the surface is exposed to light. (1)O2 may diffuse from the coating and has the potential to kill microorganisms present on the surface. In the present study a derivative of the meso-tetraphenylporphyrin (TPP) was immobilized onto polyurethane (PU) after being sprayed and polymerized as a thin laye...
Photodynamic inactivation (PDI) is an alternative to antibiotic therapy method for biocidal action against microorganisms, which can be used lithotripsy and sanitation of the bladder cavities. Objective. Selection parameters application PDI uropathogenic microorganisms. Materials Methods. In this study we bacterial strains isolated from urine samples patients. Differentiation media biochemical ...
The use of Antimicrobial Photodynamic Therapy (APDT) as a new approach to treat localized Candida infections is an emerging and promising field nowadays. The aim of this study was to verify the efficacy of photodynamic therapy using two new benzo[a]phenoxazinium photosensitizers against Candida albicans biofilms: N-(5-(3-hydroxypropylamino)-10-methyl-9H-benzo[a]phenoxazin-9-ylidene)ethanaminium...
BACKGROUND Photodynamic therapy (PDT) has been found to be effective in inhibiting biofilm producing organisms. We investigated the photodynamic effect of gold nanoparticle (GNP) conjugated photosensitizers against Candida albicans biofilm. We also examined the photodynamic efficacy of photosensitizer (PS) conjugated GNPs (GNP-PS) to treat skin and oral C. albicans infection in BALB/c mice. M...
