...Brian Medawar, who has been working on tissue transplants for the past 17 years. Experimenting with laboratory animals, Medawar was among the first to describe the mechanism of the puzzling "rejection reaction"-the process by which the human body develops antibodies similar to those it uses against viruses and bacteria to reject and destroy tissue transplants intended to replace diseased parts...
...that the chaparral on the nearby Verdugo Mountains is all that keeps Glendale from being washed away by flood. Studying plants, they found those that best sustain this growth, e.g., black mustard. They analyzed the city water supply, found it pure but dwindling. Armed with petri dishes, they made bacteria counts in restaurants, groceries, the city jail, restrooms and hospitals. They measured noise, nutrition, recreation, garbage disposal-literally everything that helps or hinders man in Glendale...
...performs these stunts is a sort of microscope in reverse. One end looks at a page of print or a pattern of parallel lines, and the train of small lenses at the other end forms an exact and tiny image. Individual letters on the negative are hardly bigger than bacteria, and an excellent microscope is needed to read them...
...what happens then divides the infants into two distinct groups. In one, the staphylococci cause such obvious signs as boils. These cases are moderately infectious to those in contact with them. The other infants show no sign of illness, but are surrounded by such an aura of pullulating bacteria that they are called "cloud babies...
...staphylococci or the babies but in a mysterious third factor. In the American Journal of Diseases of Children, Dr. Eichenwald suggests that this factor operates independently of the staph. It consists, he suspects, of assorted viruses commonly found in the human respiratory tract. How these viruses team with the bacteria to act as a spreading agent is not known, but they do the job so effectively that a single cloud baby can readily infect a whole room and anybody who enters it. The viruses and bacteria do this, says the Journal, "without any hint of a sneeze" to get them...
