Copper hospital beds kill bacteria, save lives
Washington, DC – November 8, 2019 – A new study has found that copper hospital beds in the Intensive Care Unit (ICU) harbored an average of 95 percent fewer bacteria than conventional hospital beds, and maintained these low-risk levels throughout…
Targeted gene modification in animal pathogenic chlamydia
The human pathogenic bacterium Chlamydia trachomatis is the most common sexually transmitted bacterial pathogen worldwide. It is estimated to infect more than 100 million people each year and is a frequent cause of infertility. Moreover, Chlamydia trachomatis also causes eye…
