How Hard is it to Stop Untreatable Bacteria?

Every known bacteria has been tested against PDT.  Even bacteria which can NOT be stopped by antibiotics are easily destroyed with short PDT treatments.  Will they ever develop a resistance to PDT?

The ability to develop a resistance is studied with successive half kills.  The treatment is applied just enough to kill half of the bacteria on the theory that each generation will try to develp a resistance.  The toughest most deadly bacteria on earth can not develop a resistance to PDT after multiple half kills.  This proves that PDT is the ultimate treatment for bacteria.

This patient was scratched by a feral cat.  The next morning she was unable to put pressure on the foot.  Two days of double doses of 3 heavy antibiotics did not improve the condition.

Topical application of sensitizer produced the infra red photo on the right, showing bacteria uptake os sensitizer.  Fifteen minutes of laser caused an immediate cessation of pain, and the infection stopped immediately.

How Deep in the Body Can We Kill Bacteria?

We were approached by a patient who had a lethal combination of bacterial infections. Both Golden Staph and Pseudomonas were in his bladder and he had been treated with the best antibiotics for four months, which was damaging his liver and kidneys.

The doctor told this patient that the bacteria could not be stopped so they were taking him off of the antibiotics.  He was told that he had a short time to live.  When he came to us his temperature was 0.2 degrees below the point where brain death starts and he was feeling faint.

We took a urine sample and spun it down to separate the bacteria and other cells from the urine, and the sample was examined under a microscope.  It was full of dead immune cells which had lost the battle with the bacteria, mrsa and pseudomonas bacteria were very active and filled the whole screen.  The sample had a red tinge due to red blood cells having been killed by the bacteria.

Urine sample before PDT. Small white dots are pseudomonas and the white rods are MRSA.  Large cells are dead immune cells killed by the bacteria.  Red tinge is hemoglobin due to the red cells killed by the bacteria. Urine sample after PDT.  One dead red cell on the left and two dead pseudomonas cells, on on the left and one of the right.  This sample was taken one hour after starting PDT

We put sensitizer into the bladder through a catheter and waited 15 minutes for it to localize into the bacteria.  Then we applied the laser above the bladder from the front and over the kidneys and ureters from the back.

In 15 minutes the patient said "I think my temperature is gone".  This does not make sense, even if you kill all bacteria the immune system has to dispose of the inflammatory cytokines which cause the fever, and this should take 4 - 6 hours.  Just to humour the patient I checked his temperature and to my amazement it was normal.

We took another urine sample and spun it down and examined it.  There were no living bacteria present and the leukocyte debris had been purged.

This is an incredible response which simply can not be achieved by any other technology.  It is a crime that people are having limbs cut off as you read this simply because they got a golden staph infection, probably from the hospital, and the doctors find it more convenient to cut off an arm or a leg instead of treating it with PDT.
