Among various programmes of biological engineering developed in the twentieth century eugenic sterilization is one of the most notorious. The reasons are numerous, ranging from its application under the Nazi regime to its post-1945 application in the Scandinavian countries, the recent sterilization of the Roma in the Czech Republic, and China’s birth planning policies. Yet it is only in the pas...

Surgical site infections (SSI) are a leading cause of complications and mortality in patients admitted to hospitals low resource countries. These largely result lack proper sterilization. Sterilization requires high heat pressure typically provided by gas powered autoclaves that may not be readily available. Unclean surgical equipment leads growth bacteria patients. This paper examines the effe...

Inadequate flexible endoscope reprocessing has been associated with infection outbreaks, most recently caused by carbapenem-resistant Enterobacteriaceae. Lapses in essential device reprocessing steps such as cleaning, disinfection/sterilization, and storage have been reported, but some outbreaks have occurred despite claimed adherence to established guidelines. Recommended changes in these guid...

New disinfection methods include a persistent antimicrobial coating that can be applied to inanimate and animate objects (Surfacine), a high-level disinfectant with reduced exposure time (ortho-phthalaldehyde), and an antimicrobial agent that can be applied to animate and inanimate objects (superoxidized water). New sterilization methods include a chemical sterilization process for endoscopes t...
