Helicobacter pylori might be readily affected with photodynamic therapy (PDT) by weak wavelengths, because it has few repair genes. Recently, gastrointestinal endoscopy emitting specific wavelengths (narrowband imaging, NBI) has been developed for the early detection of tumors. Coincidentally, its wavelength (415 nm) is very similar to the wavelength (410(More)
Infection with Clostridium difficile (C. difficile) causes a severe colitis with high recurrence. Treatment of C. difficile infection (CDI) is based on antibiotics in spite of the increase of resistance. To interrupt the vicious cycles such as new antibiotics treatment and appearance of resistance strains, photodynamic therapy (PDT) might be a possible(More)
Antibiotic resistance in animal isolates of enterococci is a public health concern, because of the risk of transmission of antibiotic-resistant strains or resistance genes to humans through the food chain. This study investigated copper resistance and its relationship with erythromycin resistance in 245 enterococcal isolates from bovine milk. Phenotypic and(More)
