1,000-year-old onion and garlic eye remedy kills MRSA

BBC News 31 March 2014

A 1,000-year-old treatment for eye infections could hold the key to killing antibiotic-resistant superbugs, experts have said.  They were “astonished” to find it almost completely wiped out staphylococcus aureus, otherwise known as MRSA.  Their findings will be presented at a national microbiology conference.

Harmless bacteria may be helpful against meningococcal outbreaks

(Infectious Diseases Society of America 26 March 2015) Nasal drops of harmless bacteria can inhibit a related bug that sometimes causes meningococcal disease, according to new findings published online in Clinical Infectious Diseases. The study — conducted among college students, a group at higher risk for this often serious illness — suggests a new approach that could help suppress outbreaks of the disease, if supported by future research.

MDC researchers greatly increase precision of new genome editing tool

(Max Delbrueck Center for Molecular Medicine (MDC) Berlin-Buch 25 March 2015) CRISPR-Cas9 is a powerful new tool for editing the genome. For researchers around the world, the CRISPR-Cas9 technique is an exciting innovation because it is faster and cheaper than previous methods. Now Dr. Van Trung Chu and Professor Klaus Rajewsky and Dr. Ralf Kühn, have found a solution to considerably increase the efficiency of precise genetic modifications by up to eightfold.
