After many cycles of this, they opened the jars. The dry soil inside was still alive with bacteria which had triumphantly survived "Martian" dryness and cold. The hardiest strains could reproduce during warm spells when the moisture content of their soil was only two-fifths of 1%. When the moisture rose above 1%, as it may during the Martian spring when the icecap melts or evaporates, the bacteria throve...
CLAIM: mixed infections caused by two kinds of bacteria may need mixed antibiotics. ANSWER: such infections are rare, except in wounds, and can best be treated then by proper choice of drugs in the right amounts-not by trusting to luck that a manufacturer's choice of items and dosage will turn out to be right...
CLAIM: when a patient's life is in danger, and there has not been time to identify the disease-causing bacteria, two or more drugs provide insurance. ANSWER: this is true only if both are used in full doses-the danger is that in a fulminating infection a patient will get a packaged combination containing only half doses of each antibiotic...
CLAIM: a second antibiotic may delay the emergence of bacteria which are resistant to the first antibiotic. ANSWER: this may be true in-test tubes, but generally there is no proof that it works in human patients...
...medium. The walls of nature's cells are permeable to specific chemicals and to electric currents. The Cash men see no reason why their synthetic cells (which are about the same size) should not be trained to behave in this way too. They are not trying to synthesize bacteria or protozoa, but there is at least a possibility that Cash's capsules can be made to resemble the neurons (nerve cells) of the human brain and to take over some of their functions...
