This relatively light incidence of influenza has not, however, abated fear of and interest in this respiratory disease. When the University of Chicago officially announced that its Isidore Sydney Falk had isolated the causative germ, the Streptococcus polymorphous (TIME, Dec. 23), the news spread with the celerity of a political or murder despatch. From London Dr. David Thomson, who has worked on the same problem, said: "Proving that one has discovered the true germ of influenza is in reproducing the disease in man or in animals by this germ in pure cultures . . . this is a very important part...
...ramshackle bacteriological laboratory of the rich University of Chicago, where often "rats destroy in a night the fruits of six months' work,"* Dr. Isidore Sydney Falk has discovered, the university announced last week, the germ which causes influenza. It is the polymorphous streptococcus. When the news reached London, where investigators have been at the same problem, the London Times called Dr. Falk from bed to answer its transAtlantic telephone questions. It was 11 a. m. in London. 5 a. m. in Chicago. It was a half-hour later when Dr. Falk returned...
This polymorphous streptococcus is the changeable germ which Harvard's great hygienist Milton Joseph Rosenau told an American Medical Association Convention 13 years ago was probably the cause of many baffling infections...
From the throat of Ruth M. McKinney, one of the graduate staff working for a doctor's degree, they secured the most useful cultures. It was of the polymorphous streptococcus. It "looks like a microscopic chain of unmatched beads which a child has strung together." When this germ collects into minute, smooth colonies in the blood, it causes a cold or mild influenza. When the colonies become rough, the influenza grows severe, virulent. With the specific cause of influenza thus recognized, an intelligent way of treatment and a vaccine for prevention lies in purview...
Although scarlet fever has been recognized as a distinct disease since 1675 (by Thomas Sydenham), not until January, 1923, was a single case developed experimentally in man or lower animal. Then Dr. George Frederick Dick and his wife Dr. Gladys Henry Dick of Chicago took a hemolytic streptococcus (blood-dissolving bacilli) from a lesion in the finger of an infected nurse and injected the germs into a 25-year-old woman. She developed scarlet fever. The Dicks developed a scarlet fever antitoxin. Last week's Germans, Professors Heinrich Finkelstein and Fritz Meyer of Berlin, claimed to have found...
