Recent progress in knowledge of the tubercle bacillus gives color to hopes that the deadly little beast may in the near future surrender unconditionally to the siege of preventive medicine. The most interesting med-cal news of the week was the, announcement by Dr. Georges Dreyer, professor of pathology at Oxford University, of a successful method of inoculation in tuberculous guinea-pigs and other animals...
...bacteria (such as the typhoid bacillus) yield readily to the " antibodies" produced by the injection of dead bacteria of the same disease. But the acid-fast germs are encased in or contain fatty cells called " lipoids," which resist digestion when injected into the body and thus generate no antibodies. Dreyer's idea is to pickle the serum consisting of dead tubercle bacilli in formalin, a solution of formaldehyde. This eats away the fatty cells of the tubercle bacillus, which can then be digested by the body juices, and calls forth a plentiful supply of the antibodies when injected. They...
