The circumstantial detection anddetailed monitoring of the intensity and growth of different pathogenic bacteria inclinical patients as well as tests of drug sensitivity during burn recovery areparticularly important to provide guidelines for the application of antibiotics andother related drugs. Careful collection and correct, standard culture of bacterialspecimens are also crucial to improve the efficiency of bacterial infectiondetection. Effective monitoring and timely clinical treatment in patients may helpreduce the possibility and rate of infection as well as alleviate the effects of drugresistance among patients in burn centers.展开更多
