Manuka Honey May Reverse Antibiotic Resistance

(NaturalNews) In less than a week, three different research studies have been released about antibiotic-resistant super bugs. Two were issued as nothing less than dire warnings. For example, as NaturalNews covered earlier, UK scientists are calling for the "urgent need for global action" due to the discovery of a spreading phenomenon -- a gene that is turning bacteria into not just super bugs but SUPER superbugs.

On the heels of that report, the Infectious Diseases Society of America (IDSA) has just sounded the alarm that an impending "health care disaster" is looming unless Big Pharma can find new drugs to combat deadly antibiotic-resistant super bugs.

Tired of all this bad news? Keep reading. Because amid all this gloom-and-doom about the threat of deadly super bugs comes yet another study from a third group of scientists that reaches a new and hopeful conclusion.

It turns out these researchers have found a way to battle life-threatening super bugs naturally with manuka honey. In fact, manuka honey could be an efficient way to clear chronically infected wounds and could even reverse super bug bacterial resistance to antibiotics.

Those are the results of a report just presented at the Society for General Microbiology's Spring Conference in Harrogate in the UK. Professor Rose Cooper from the University of Wales Institute Cardiff is investigating how manuka honey interacts with three types of bacteria that commonly infest wounds: Pseudomonas aeruginosa, Group A Streptococci and Methicillin-resistant Staphylococcus aureus (MRSA). She and her research team have discovered that honey can interfere with the growth of these bacteria in a multitude of ways. And that makes honey a strong option for the treatment of drug-resistant wound infections.

The idea that honey has antimicrobial properties is nothing new. In fact, traditional therapies containing honey were used in the topical treatment of wounds by numerous ancient civilizations. Professor Cooper is particularly interested in the super bug-fighting potential of manuka honey, which comes from nectar collected by honey bees foraging on the manuka tree in New Zealand.

Although manuka honey is found in modern wound-care products sold around the world, the anti-infection properties of the honey have not been used much by mainstream medicine. According to a press statement, Professor Cooper's group believes this is because the mechanisms of the honey's germ zapping action haven't been known. So they are working to document just how manuka honey halts wound-infecting bacteria, including super bugs, on a molecular level.

"Our findings with streptococci and pseudomonads suggest that manuka honey can hamper the attachment of bacteria to tissues which is an essential step in the initiation of acute infections. Inhibiting attachment also blocks the formation of biofilms, which can protect bacteria from antibiotics and allow them to cause persistent infections," explained Professor Cooper in a media statement.

"Other work in our lab has shown that honey can make MRSA more sensitive to antibiotics such as oxacillin -- effectively reversing antibiotic resistance. This indicates that existing antibiotics may be more effective against drug-resistant infections if used in combination with manuka honey."

The researchers believe their findings may increase the clinical use of manuka honey as doctors are faced with the threat of diminishingly effective systemic antibiotics now used to try and control wound infections. "We need innovative and effective ways of controlling wound infections that are unlikely to contribute to increased antimicrobial resistance," said Professor Cooper. "The use of a topical agent (manuka honey) to eradicate bacteria from wounds is potentially cheaper and may well improve antibiotic therapy in the future. This will help reduce the transmission of antibiotic-resistant bacteria from colonized wounds to susceptible patients."

Top Public Places Where The Most Germs Lurk

It is possible for a person to touch about 30 things in one minute from daily and normal activities.  This heightens the chance of contracting and spreading germs to and from all these objects if in a public setting.  But there are ways to avoid being infected by knowing the more obscure places germs hide other than door knobs, light switches, and bathroom surfaces. 
Restaurant menus
Studies from the Journal of Medical Virology reports germs like the cold and flu viruses can survive for up to 18 hours on a hard surface.  When dining in a public place, be conscious to not let the menu touch your flatware and wash your hands after you return it.
Lemon wedges
The Journal of Environmental Health discovered 70 percent of restaurants had contaminated bar fruit with microorganisms like E. coli, fecal bacteria, and other disease causing microbes.  By opting out of the garnish for your beverage is a good way to prevent ingestion.
Condiment dispenser
Many people do not wash their hands before eating and they can spread their germs to bottles at the condiment stand.  When grabbing for the ketchup, a paper napkin is not sufficient due to the abilities for microorganisms being able to pass through.

Restroom door handles

Don't think you can escape the restroom without touching the door handle? Palm a spare paper towel after you wash up and use it to grasp the handle. Yes, other patrons may think you're a germ-phobe--but you'll never see them again, and you're the one who won't get sick.

Soap dispensers

About 25% of public restroom dispensers are contaminated with fecal bacteria. Soap that harbors bacteria may seem ironic, but that's exactly what a recent study found. "Most of these containers are never cleaned, so bacteria grow as the soap scum builds up," says Charles Gerba, PhD. "And the bottoms are touched by dirty hands, so there's a continuous culture feeding millions of bacteria." Be sure to scrub hands thoroughly with plenty of hot water for 15 to 20 seconds--and if you happen to have an alcohol-based hand sanitizer, use that, too.

Grocery carts

The handles of almost two-thirds of the shopping carts tested in a 2007 study at the University of Arizona were contaminated with fecal bacteria. In fact, the bacterial counts of the carts exceeded those of the average public restroom. Swab the handle with a disinfectant wipe before grabbing hold (stores are starting to provide them, so look around for a dispenser). And while you're wheeling around the supermarket, skip the free food samples, which are nothing more than communal hand-to-germ-to-mouth zones. 

Airplane bathrooms

When Gerba tested for microbes in the bathrooms of commercial jets, he found surfaces from faucets to doorknobs to be contaminated with E. coli. It's not surprising, then, that you're 100 times more likely to catch a cold when you're airborne, according to a recent study in the Journal of Environmental Health Research. To protect yourself, try taking green tea supplements. In a 2007 study from the University of Florida, people who took a 450-milligram green tea supplement twice a day for 3 months had one-third fewer days of cold symptoms. The supplement brand used in the study was Immune Guard ($30 for 60 pills; immune-guard.us).

Doctor's office

A doctor's office is not the place to be if you're trying to avoid germs. These tips can help limit your exposure. 1. Take your own books and magazines (and kid's toys, if you have your children or grandchildren with you).
2. Also pack your own tissues and hand sanitizers, which should be at least 60% alcohol content.
3. In the waiting room, leave at least two chairs between you and the other patients to reduce your chances of picking up their bugs. Germ droplets from coughing and sneezing can travel about 3 feet before falling to the floor.
