Are Antibiotic-Resistant Diseases Mother Nature’s Revenge?
The methicillin-impervious infection Staphylococcus aureus is the most common post-surgery illness.

Resistance to antibiotics is often described by neo-pagans as Mother Nature’s vengeance on Man for having had the temerity to interfere in her natural biological processes. According to the neo-pagans, this vengeance has left Man (deservedly) worse off than if he had never discovered antibiotics at all. I do not see the logic of this.
There is no doubt, however, that bacterial resistance to antibiotics is a serious problem worldwide. It is particularly serious in hospitals, where patients may pick up infections that they never had before admission. Many patients die from these infections, which may be of epidemic proportions.
The most important such infection is MRSA, methicillin-resistant Staphylococcus aureus. (Methicillin is a semi-artificial penicillin that was developed when the Staphylococcus first became resistant to ordinary penicillin, and soon met with resistance itself.) MRSA accounts for most post-surgical infections; the proportion of patients infected by it is often taken in research as a measure of a hospital’s hygiene.
An important paper in a recent edition of the New England Journal of Medicine compares various strategies for reducing the spread of MRSA in intensive care units, a common place for patients to become infected.
The method of control usually employed is to screen patients for MRSA on admission to the ICU and to institute special precautions such as isolation and barrier nursing if they test positive. The authors compared this method with attempts by means of antibacterial products at “decolonization” of those who tested positive, and similar “decolonization” practiced on every patient admitted to an ICU irrespective of whether or not he tested positive for MRSA.
