...soon go the way of pink toothbrush. Just at the peak of the chlorophyll rage, U.S. toothpaste makers are beginning to switch to "enzyme inhibitors," developed at Northwestern University's Dental School. The new theory is that tooth decay is caused by enzymes (i.e., chemical agents produced by bacteria) turning sugars and starches into acids. Last week Lambert Co., Colgate, and Block Drug Co. were already hard at work on new anti-enzyme toothpastes, hope to have their new products on the market this fall. Said the American Dental Association: "The value of anti-enzymes . . . still remains...
Botulism, the deadliest of all food poisonings, was reported only twice, but it killed four of its five victims. Since the bacteria which secrete botulin can thrive only when they are carelessly sealed in a nourishing medium without air, botulism nowadays is associated with home canning. In California, two victims ate home-canned mushrooms; in Oregon, two ate home-canned beets. They would have been all right if they had reboiled the food...
Benjamin Harrison was in the White House; in Paris, Professor Louis Pasteur was working out his theories on bacteria; and in Würzburg, Wilhelm Konrad Röntgen was on the threshold of discovering the X ray, with scarcely a glimmering of the wonderful and terrible world of radioactivity that lay beyond. At Washington's Smithsonian Institution, itself only 46 years old, a 23-year-old instrument maker named Andrew Kramer applied for a job. Secretary Samuel P. Langley hired him on trial, that October day in 1892, to equip his astrophysical observatory. Last week...
...fobbed them off with vague excuses. They made no bacteriological tests themselves, and they did no on-the-spot laboratory work on infected insects supposed to have been airdropped. They did not examine a single patient of the many who, the Reds said, had been made ill by airborne bacteria...
...only important bacteria that have shown significant resistance, Sir Alexander insisted, are the staphylococci (which cause boils and wound infections), and he denied that these have become resistant after exposure to the drug. These strains were resistant all along, he argued, but made up only 2-3% of the staphylococci; now they are involved in 50% of cases treated in hospitals and 10% of those treated outside-but only because penicillin has killed off the other strains...
