...that Fleming got a bigger share than he deserved of the credit for penicillin-that more should have gone to Sir Howard Florey and Dr. Ernst Chain, who first took it out of the lab and put it into a patient. In the U.S., doctors say that strains of bacteria resistant to penicillin are emerging everywhere, and that these may breed diseases from which penicillin can give no relief...
...ancients believed, says Dr. Philip, that mashed ticks were a useful aphrodisiac, and Pliny the Elder recommended tick blood as a depilatory and as a curative ointment. There may be something to this. Recent tick-workers have shown that ticks contain an antibiotic that inhibits the growth of many bacteria...
...valuable and widely used antibiotics can cause death if the physician employing them is not careful, warned the Mayo Clinic's Dr. P. T. Sloss. The trouble is most likely to develop on the fourth day of treatment with aureomycin or terramycin. The drugs kill many of the bacteria normally found in the intestine, and give a chance for resistant strains of staphylococci to multiply and poison the system. In such cases (so far, rare), the patient gets symptoms like those of cholera, and will die in a day or two, Dr. Sloss said, unless the drugs are promptly...
...Bryan persuaded youths and adults of both sexes to plant their lips firmly against sterile glass slides or gooky agar plates while he held a stop watch. After intervals ranging from two to ten seconds, he took the specimen and cultured it to see how many colonies of bacteria had been transferred. His chief findings...
...drugs may work well against one kind of disease-causing microbe and be useless against another closely related microbe. Fortunately, the exceptional cases in which drugs from Groups I and II should be used together are those which have often proved hardest to treat-where a strain of bacteria shows extreme resistance to a widely used antibiotic like streptomycin. But even in these cases laboratory tests have proved better than guesswork...
