New substances completely kill bacteria that cause pneumonia

A team of researchers who have successfully developed a new compound that produces nitric oxide when exposed to light can help patients with deadly bacterial infections Acinetobacter baumannii.

When sprayed directly on the wound, nitric oxide will kill A. baumannii in light environments, even only a few daylight.

This method will avoid the byproducts of nitric oxide reaction going into the wound which is retained in the powder material. So it only allows nitric oxide to enter the body to become antibacterial and the patient does not suffer from other side effects.

To test the effect of the new compound, the team raised A.baumannii bacteria that allowed them to grow to the point where they could infect human skin and soft tissues. The group then experimented on an injured soldier. At the same time, give this person exposure to light at a intensity of 100mW per square centimeter. Results in 24 hours of treatment, bacteria were completely erased.

Now researchers plan to continue testing new compounds on animals to further develop this treatment.

It is known that A.baumannii bacteria entering the body through open wounds often attack the immune system, causing fever, swelling, difficulty breathing and headaches. The disease caused by A.baumannii has attacked many US soldiers in Iraq, urging American scientists to study treatment.
