Bacterial infection is recognized as one of the biggest global health threats,causing millions of people's death every year(Wang et al.,2020).Traditional antibiotics-based therapies have been widely utilized to control this issue(Kohanski et al.,2010);however,their excessive use leads to the emergence of antibioticresistant bacteria,endangering to human health(Levy and Marshall,2004).
