DECREASED PERMEABILITY AS THE MECHANISM OF ARSENITE RESISTANCE IN PSEUDOMONAS PSEUDOMALLEI.

abstract：:Horizontal gene transfer by conjugation plays a major role in bacterial evolution, allowing the acquisition of new traits, such as virulence and resistance to antibacterial agents. With the increased antibiotic resistance in bacterial pathogens, a better understanding of how bacteria modulate conjugation under changin...
