There is growing evidence that the major cause of MRSA is the inappropriate over prescribing of antibiotics by general practitioners. This is not news and it is common knowledge that most infections are viral and do not require antibiotics.
Also it is well known that antibiotics upset gut bacteria and lead to overgrowth of the intestinal tract with fungi such as Candida which is present in everyones guts, but normally kept in check by the probiotic bacteria surrounding it and which also produce chemicals to keep it in check. Antibiotic use can reduce the probiotic bacteria and allow the fungus to grow which over time can lead to inflammation and misdiagnosis of IBS later in life and open another chapter in prescribing. A downward spiral we dont want to promote. Candida overgrowth and dysbiotic guts probably affect millions of 20 somethings who have just had years of antibiotics for acne, or million of 40 somethings who have been put on antibiotics for rosacea. We have clever ways of restoring the normal bacterial balance and reducing Candida without harsh antifungals.
However the use of antibiotics for skin infections such as acne and rosacea often at low doses...
