New antibiotic that attacks MRSA found in ocean microbe

RATE THIS! +23

The discovery of genuinely novel antibiotics is rare, and experts say resistance to the drugs poses a grave threat to human health. US scientists say the new compound, called anthracimycin, seems to be effective against MRSA and anthrax.

 

Details appear in the German journal Angewandte Chemie. The unique chemical structure of the compound could lead to a new class of antibiotic medicines.

 

Thomas Frieden, director of the US Centers for Disease Control and Prevention, recently warned of the risk posed by antibiotic-resistant "nightmare" bacteria while Sally Davies, UK Chief Medical Officer described them as a "ticking time bomb" that threatens national security.

 

The Infectious Disease Society of America has expressed concern that the rate of antibiotic development to counter resistance is insufficient. This makes this latest discovery particularly welcome news.

 

The structure of anthracimycin, described by Kyoung Hwa Jang and co-workers from Scripps in their journal paper, is unlike any previously-reported natural antibiotic.The compound was extracted from Streptomyces bacteria that had been collected by Christopher Kauffman in Pacific Ocean sediments.

 

Leader of the team of researchers, William Fenical, commented: "The real importance of this work is that anthracimycin has a new and unique chemical structure. The discovery of truly new chemical compounds is quite rare. This discovery adds to many previous discoveries that show that marine bacteria are genetically and chemically unique."

 

Initial testing of the antibiotic compound has demonstrated its efficacy in attacking anthrax, a bacterium that has been used as a bioterrorism weapon. But it also showed significant activity against Staphylococcus aureus, the MRSA superbug.

This is a really good job that has been done by the US research scientist. This new antibiotic by the name of anthracimycin, seems to be effective against MRSA and anthrax. Reply

The researchers feel that the rate of antibiotic development to counter resistance is insufficient. With this new drug, it will be possible to have a new strain that will be able to be used for both the Anthrax and the MRSA. Maybe it could be used for other purposes also. Reply
