...scene is a du Pont Corporation board meeting. The board of officers is gathered awaiting the arrival of P.S. du Pont, their president. His absence is baffling. He is punctilious about company matters, and he never misses a board meeting. The officers begin to speculate that perhaps the influenza epidemic or a terrible accident has stricken the boss. He, in fact, is missing the meeting to be at the sick bed of his chauffeur--his only true friend. Mosley contrasts P.S.'s affection for his servant with his marked coldness toward his wife. P.S. is the first of many...
...substance that has caused all this excitement was discovered in 1957 by Virologists Alick Isaacs and Jean Lindenmann. Isaacs, who died of a nonmalignant brain tumor at age 45 in 1967, was investigating influenza viruses at London's National Institute for Medical Research. There he met Lindenmann, who had arrived from Switzerland in July 1956. Lindenmann, now head of experimental microbiology at the University of Zurich, stayed in London only a year. But it was time well spent. Over a cup of tea that August, the two scientists discovered a mutual fascination with a biological phenomenon known as viral interference...
...Isaacs and Lindenmann had the answer by early the next year, a remarkably quick solution to a major scientific puzzle. In a series of experiments, they took pieces of the thin membranes that line the inside of chicken eggshells, grew them in a nutrient solution, and exposed them to influenza viruses. When they added other viruses to the culture, they found that the cells resisted further infection. True to form, the first set of viruses seemed to be thwarting the attack of the second. The researchers next removed all traces of viruses and chicken cells, leaving only the culture brew...
...heavy red blood cells sink to the bottom, white cells settle just above, and the liquid plasma rises to the top. The Red Cross keeps the plasma and red cells for transfusions and turns the white cells over to Cantell. He infects the leukocytes with Sendai virus, an influenza-like virus harmless to humans, and incubates them at 37.5? C (99.5? F) for 24 hours. The resultant IF solution is centrifuged to separate out the white cells and partly purified to destroy the virus. What remains is a highly impure IF preparation; even after it is partly purified it consists...
...Center for Disease Control in Atlanta reported earlier this month that children and teenagers from ages five to 19 are most susceptible to this type of influenza...
