Emergence of Azithromycin Resistance Mediated by Phosphotransferase-Encoding mph(A) in Diarrheagenic Vibrio fluvialis.

abstract：:Most of our knowledge relating to molecular mechanisms of human fungal pathogenesis in Candida albicans relies on reverse genetics approaches, requiring strain engineering. DNA-mediated transformation of C. albicans has been described as highly mutagenic, potentially accentuated by the organism's genome plasticity, in...
