...Robertson placed groups of mice in a chamber and sprayed its air first with propylene glycol, then with influenza virus. All the mice lived. Then he sprayed the chamber with virus alone. All the mice died...
...local epidemic of encephalitis among the horses. So, the two Army doctors urge, medical doctors should work closely with veterinarians, since horses can be immunized almost 100%. Hooper Foundation researchers in California and Washington have recently proved that many barnyard animals, principally domestic fowl, act as reservoirs for the virus, presumably transferred to man by mosquitoes...
...particular he warned the onslaught of "virus Pneumonia" which is apparently spreading. Although the disease is rarely, if ever, fatal, Dr. Bock pointed out that a loss of two to three weeks could be expected...
...Caltech biochemists believe that their discovery is further proof that immunization, whose physiological mechanics has long been a major mystery, is a molecular phenomenon. In the blood stream of animals are large protein molecules called serum globulin. If a bacterium, virus, poison molecule or other "antigen" is near the point where these molecules are formed, the adaptable globulin molecules change their shape and assume structures complementary to those of the invading antigens, so that they can combine with them and neutralize them. After the infection or poisoning has been overcome, these changed globulin molecules remain in the blood as antibodies...
Similarly, pneumonitis may be caused by a new type of virus which never before existed. It may become more virulent, or peter...
