我们设计并制造了一个微生态学来模拟自然发生的细菌培养,其中包括应力梯度,集合种群和细胞运动。在这个微生态学中,我们表明,它是可能的,以固定的突变抗生素环丙沙星在野生型大肠杆菌在10小时内的耐药性。我们发现,如果细菌已经获得了稳定期生长优势(GASP)的表型,则在微生态中抗性的进化会进一步加速。
We have designed and fabricated a microecology to mimic a naturally occurring bacterial culture, which includes the stress gradient, metapopulation, and cellular motility. In this microecology, we show that it is possible to fix the resistance to the mutagenic antibiotic Ciprofloxacin in wild-typeEscherichia coliwithin 10 h. We found the evolution of resistance is further accelerated in microecology if bacteria have already acquired the phenotype of growth advantage at the stationary phase (GASP).
