Scientists presently discover a compound that kills 98% of a drug-resistant-bacteria

Researchers have exposed a complex in an Antarctic sea sponge that's capable of killing 98 percent of the drug-resistant superbug, methicillin-resistant Staphylococcus aureus - improved known as MRSA - which is quickly spreading throughout the US.
With more and extra bacteria species becoming opposed to to the antibiotics we have obtainable, scientists are desperately looking for latest ways to protect next to infection, and early on research suggests that the Antarctic sponge could be an option.
Staphylococcus aureus - or staph - infections are attractive common, chiefly in hospital settings, and under normal circumstances they're not chiefly hard to treat. But MRSA is a strain that's developed resistance to the majority of the antibiotics we have obtainable, which means it can fast spread from a superficial infection, such as a skin disease, to an all-encompassing one, which can be life-threatening. 
According to the Centres for Disease Control (CDC), about 80,000 MRSA infections are diagnosed in the US each year, and 11,000 citizens die from MRSA complications - and right now, we actually don't have many options to fight them.
Which is why the finding of this new compound, which has been name 'darwinolide', is so exciting. Researchers found it within an Antarctic sponge, Dendrilla membranosa, and initial lab test have shown that it's clever to kill 98.4 percent of MRSA cells. 
"It's a defensive compound next to microbes with some very attractive properties," said one of the researchers, James McClintock, from the University of Alabama at Birmingham.
It's still very early on days, but this isn't the first time that medically attractive compounds have been start lurking in the ocean organisms in Antarctica - McClintock and his team have by now identified a compound in algae that fight the H1N1 strain of the flu virus, and one more that acts next to melanoma skin cancer.
The appeal for biologists is that the area is so extreme that life has been forced to come up with some unique ways to survive - including a number of potent defence mechanisms, such as toxic compounds.The researchers have currently patented the mix, but are still in the process of understanding precisely how it works. Lab tests so far suggest that it has a single structure that allows it to penetrate the 'biofilm' that MRSA throws up to defend itself from treatments.
"When we take antibiotics, they're chase bacteria in fluids," says McClintock - which is why they're so often useless next to MRSA.
"Darwinolide differ from previous, somewhat similar, drug candidate from sponges because its central ring structure is rearranged in an strange way," added one of the researchers, Charles Amsler.
"If that reorganization of the chemical backbone is in part responsible for the effectiveness next to biofilm bacteria, it strength be able to serve as a chemical scaffold for the growth of other kinds of drugs targeting pathogens within biofilms."
The after that step is to synthesise darwinolide in the lab, so they don't have to rely on extract it from live Antarctic sponges. This will give further insight about its arrangement, and will help the team work out precisely how it fights MRSA, and whether it could be turned into a action one day. 
If the researchers are able to show that they can use darwinolide to fight MRSA in a clinical location, it might save the lives of tens of thousands of people every years, so we're cute keen to see what happens next.
