       科学家们发现，一种普通抗生素清除了蜜蜂体内有益的肠道细菌，使有害病原体获得了立足之地，而这种病原体也会发生在人类身上。

       得克萨斯州奥斯丁 - 德克萨斯大学奥斯汀分校的研究人员发现，与一组未经处理的蜜蜂相比，用普通抗生素治疗的蜜蜂在治疗后一周的存活率只有一半。

       这一发现可能对蜜蜂和与蜜蜂类似的人类都有健康方面的影响。

Overuse of Antibiotics Brings Risks for Bees — and for Us

Scientists found that a common antibiotic cleared out beneficial gut bacteria in the bees, making way for a harmful pathogen, which also occurs in humans, to get a foothold

Honeybees treated with a common antibiotic (pink dots) were half as likely to survive the week after treatment compared with a group of untreated bees (green dots).

AUSTIN, Texas — Researchers from The University of Texas at Austin have found that honeybees treated with a common antibiotic were half as likely to survive the week after treatment compared with a group of untreated bees, a finding that may have health implications for bees and people alike.

The scientists found the antibiotics cleared out beneficial gut bacteria in the bees, making way for a harmful pathogen, which also occurs in humans, to get a foothold. The research is the latest discovery to indicate overuse of antibiotics can sometimes make living things, including people, sicker.

蜜蜂是研究抗生素对肠道细菌作用的非常好的模型。它们的消化系统中含有调节行为、发育和免疫的特定细菌，这与人类相似。
