Antibiotic resistance doesn’t just
make pathogens(病原体) difficult to treat, It also makes them harder to track
Traditionally, epidemiologists(流行病专家)following the paths of disease-causing
microbes have identified their suspects by features of bacterial
polysaccharide(多糖) coats, susceptibility to different antibiotics, or other
schemes But these tracking techniques "are losing their relevance (相关性,实用性),
"says Alexander Tomasz, a microbiologist at Rockefeller University in New York
City. With the increase in drug resistance, a variety of resistant microbes can
now wear the same coat or be resistant to the same drugs, making it harder and
harder to keep tabs on individual strains (菌株). Epidemiologists, therefore, are increasingly turning to more precise molecular typing techniques, such as DNA fingerprinting, to distinguish resistant strains. [判断题]现场心肺复苏应坚持不断地进行,如需将伤员由现场移往室内,中断操作时间不得超过7s;通道狭窄、上下楼层、送上救护车等的操作中断不得超过30s。( )
