A team of researchers from the National University of Singapore (NUS) has uncovered the mystery behind the potent parasite-killing effect of artemisinin, a drug that is considered to be the last line of defense against malaria. Given the emergence of artemisinin resistance, these findings could potentially lead to the design of new treatments against drug-resistant parasites.
The bacterium B. cereus had so far been considered to be exclusively endospore-forming. In response to harsh conditions, the bacteria form protective endospores enabling them to remain dormant for extended periods. When conditions are more favorable, the endospores reactivate to become fully functioning bacteria.
Jesuit High School of New Orleans is the first and only prep school in the United States to deploy a high-tech Germ-Zapping Robot™ to wage environmental war by destroying bacteria and potentially deadly pathogens typically found lurking inside gymnasiums, athletic locker rooms, weight training areas, shower and bathroom facilities, and even personal sports equipment.
Researchers at the University of Georgia found that pathogens, like salmonella, can survive for at least six months in cookies and crackers. The recent study was prompted by an increased number of outbreaks of foodborne diseases linked to low-water-activity, or dry, foods.
Here's a review of ICT's top news, features and slide shows relating to environmental hygiene in 2015.
In 2015, the World Health Organization (WHO) led the health response to major outbreaks and emergencies from West Africa to Iraq. It provided new advice on a broad range of health issues, including dementia, food safety, HIV treatment, sugar consumption, antibiotic resistance and climate change. The organization also marked the end of the 15-year era of the Millennium Development Goals and saw the launch of the Sustainable Development Goals for the next 15 years.
