Quarter-sized microarray can detect 9,000 different types of bacteria

Posted December 20, 2006 7:07 AM

From What's Next In Science & Technology:

Want biodiversity? Look no further than the air around you. It could be teeming with more than 1,800 types of bacteria, according to a first-of-its-kind census of airborne microbes recently conducted by scientists from the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab). The team used an innovative DNA test to catalog the bacteria in air samples taken from the Texas cities of San Antonio and Austin. Surprisingly, they found a widely varied bacterial population that rivals the diversity found in soil. They also found naturally occurring relatives of microbes that could be used in bioterrorist attacks — although many of these relatives are harmless. Read more!

I was just wondering about this the other day. Its amazing that they can sell antibacterial lotion when the air you breath contains thousands of bacteria each breath.

This is very true and the use of many so called antibacterial lotions can be a waste of time. However having said that prevention is always better than a cure and will give you a couple of personal experiences where I would have preferred the prevention concept.

I have been battling with a wound that became infected with Methicillin Resistant Staphylococcus aureus MRSA for nearly two years now and there is no end in sight. The only chance with superbugs like MRSA and VRSA is never to get infected with them in the first place. That means hygiene and regularly washing your hands with an antibacterial agent. Any person that is unfortunate to become infected with these superbugs needs to have special care and scrupulous hygienic procedures is the only chance of arresting its spread from person to person and even from wound to wound.

Food handling is another place that is open to problems like cross contamination and spoiling. Cross contamination can be as simple as handling raw chicken and then some time later handling prepared food that is ready to eat. If you havn't washed your hands and all the utensils, including the chopping board, in the interim you stand a good chance of transferring nasties like campyulobacter. This is a very painful nauseating gut wrenching infection that will result in you body draining the entire gastrointestinal tract from both ends simultaneously. I can tell you from experience that this is a exceptionally awfully extremely unpleasant experience that is best avoided.

So yes while there are many airborne nasties that will re-contaminate anywhere you wash with antibacterial lotions and soaps there are some really obnoxious, highly infectious, horribly vicious nasties that can only be kept at bay by regular washing with soap and/or a reputable antibacterial lotion.

HI MASU ,

IF NOTHING WORK FOR YOUR INFECTION , I SAW THE OTHER DAY SOMETHING

INTERESTING IN "AN OLD MEDICINE NEWS PAPPER " ....ECT ...ECT ... ( AN HI-FREQUENCIES ULTRA-SONIC TREATMENT FOR DIFFERENTES TYPE OF BACTERIAS ,

-THE TRICK IS TO FIND THE PROPER ( THE RIGHT FREQUENCY ) TO KILL THOSE LITTLE CRITTERS !!! ..... ANYWAYS IN THE LAST REASORT , I WOULD TRY IT !!!

Interesting concept hydrotime. Do you have any idea of the sort of frequencies that may be effective. If you have a ball park starting point it would be easy to get a culture started and bombard it with various frequencies till the right one was found. Anything is worth a try.

Thanks for the tip.

Good old 'RENSE' never short of a ripping yarn, Take heed of his warning about costly equipment claiming to duplicate Royal Raymond Rife, but are just cheap signal generators.

There are some amazing developments underway in the opto/electronics field. These new devices now on the lab bench may have a deep impact into this exciting area of research.

Received 22 July 2006; accepted 5 October 2006; published online 22 November 2006

The authors present a technique that allows to modify the local characteristics of two-dimensional photonic crystals by controlled microinfiltration of liquids. They demonstrate experimentally that by addressing and infiltrating each pore with a simple liquid, e.g., water, it is possible to write pixel by pixel optical devices of any geometry and shape. Calculations confirm that the obtained structures indeed constitute the desired resonators and waveguide structures. © 2006 American Institute of Physics. DOI: 10.1063/1.2392720

About fifteen years ago, I needed a copper wave guide in a hurry, So I just electro-formed it in a bucket of copper sulphate solution. Cyanide was off the menu on health & safety considerations. I made the former from my favourite material, good old beeswax and graphite....a final dusting of graphite with a soft brush, start electroplating with an old 1.5 volt torch battery till the former is salmon pink all over, then away you go at full current density. Melt out the beeswax after and clean up the interior....jobs a good-un.

So this bucket of copper sulphate + weak sulphuric acid, lays around collecting dust for a year. under a table with the plastic lid in. I used scrap copper buzz-bar for anodes wrapped in polyester to keep the solution clean of stray copper particles. these stopped the lid fully closing. ... So I go and lift this lid to inspect the contents, and to my amazement discover some moulds have grown on top of the solution. With large glass jam jars to hand, I carefully pour the copper sulphate solution into the jars, with a floating mould in each jar....... I waited.

That year I had some wonderful Christmas Presents,... These moulds would become so heavy, they sank to the bottom of the jam jars...then they started to inflate a sort of bladder/balloon, which brought them to the surface again... up and down they went. My friends placed them in their front windows for everyone in the street to admire. They became quite a talking point. "Is your mould afloat yet, mine has just sunk again" Was this mould spore blown in on the wind I wonder? I never received a reply from the U.K. Copper Development Board, to where I dispatched a few samples.
