These 3 Superbugs Pose The Greatest Risk To Human Health
The World Health Organization is issuing a warning about a group of deadly bacteria: Recently, the WHO released its first-ever list of “priority pathogens,” a list of antibiotic-resistant bacteria that the organization says pose the greatest threat to human health. The list is divided into three categories: critical-, high- and medium-priority. Three pathogens made it into the critical-priority group. These bacteria are resistant to multiple antibiotics and pose a high risk to people in hospitals and nursing homes, the WHO says. Multidrug-resistant bacteria, sometimes called “superbugs,” are a critical priority because infections with these germs can be deadly, according to the WHO. For example, people who get infections from a type of multidrug-resistant bacterium called methicillin-resistant Staphylococcus aureus (MRSA) have a 64 percent greater chance of dying than people who contract the same infection in its nonresistant form, according to the WHO. [6 Superbugs to Watch Out For] All of the top three pathogens on the list are resistant to a group of antibiotics called carbapenems. These antibiotics are sometimes referred to as “last resort” medications, because if they don’t work, very few options are left. “It is important the WHO take this on, because with travel and now widespread communication, an antibiotic-resistant organism … is going to get around the world pretty quickly,” said Dr. Ken...
BRITAIN ’S new superbug tsar says she has sleepless nights worrying that her children will live in a “post-antibiotic apocalypse” where modern medicine no longer works.
ConclusionThese findings show that prenylated flavanones, especially propolin D from Macaranga tanarius (Okinawan propolis), should be considered potential candidates for the development of non-toxic antibacterial and antifungal agents against persistent microorganisms.Graphical abstract
We gave deadly “superbugs” to the gulls, now they may give them back to us
In this study, we found the AgNPs effectively induces cytotoxicity, ROS and apoptosis by modulation of intrinsic apoptoic Bcl2, Bclxl, Bax and Caspase 3 protein expressions in LNCap cell lines. Based on the study, synthesis of AgNPs from S. miltiorrhiza shows eco-friendly and it exhibits antimicrobial and anticarcinogenic effects. PMID: 31299869 [PubMed - in process]

Professor Dame Sally Davies used her appointment as the UK's special envoy on antimicrobial resistance to urge leaders to sit up and tackle the looming drug crisis.
As the infections become increasingly resistant to antibiotics, some standard treatments no longer work for an ailment that was once easily cured.
Authors: Kim H, Kwon GE, Kim YH, Callaway Z, Han YS, Seo JJ, Jiao F, Kim CK Abstract Objective: Eosinophil-derived neurotoxin (EDN) is associated with recurrent wheezing episodes after bronchiolitis, childhood asthma, and allergic rhinitis. We investigated if there is a measurable difference between serum EDN levels in children with wheezing and non-wheezing respiratory infections. Methods: 171 children who visited a university hospital with respiratory infections were enrolled in the study. Subjects were divided into two groups: wheezing (n = 46) and non-wheezing (n = 125). Serum EDN le...

Kiran Kumar, Anindita ChatterjeeAbstractSilver (Ag) nanoparticles (NPs) were produced by a simple, one step green method using Gigantic swallow-wort leaf aqueous extract. Intrinsic structural and physiochemical properties of Ag NPs were investigated and demonstrated their applicability in biomedicine. The IR data revealed the capping of organic molecules from plant extract. Further, the fluorescence studies were carried and found the molecules exhibit excitation at 400 nm. The biological...
