...serpentine germ, Leptospira icterohemorrhagiae, causes the disease, affects the spleen and liver, yellows the eyes and skin, raises temperature, is not often fatal. Donald Siegle's pet dog had an attack of jaundice a fortnight before the child died, and may have transmitted the germ. But in the beginning, Dr. Vaughan knew, rats were responsible. Every tenth rat in any community harbors Leptospira icterohemorrhagiae, with no inconvenience to itself, but with grave trouble for man or beast who eats, drinks or touches food fouled...
...bite of infected mosquitoes and established beyond dispute that yellow fever is transmitted by the bite of infected mosquitoes of the species Stegomyia fasciata. But the commission was unable to identify the germ. Since then there have been many attempts, many false alarms. Researcher Noguchi's Leptospira icteroides has received scientific support; has come closest to being accepted as the organism responsible for yellow fever. Survivor Agramonte was never satisfied with its credentials. Both before and after Noguchi's death by yellow fever he has pointed out the similarity between Noguchi's leptospira and the leptospira which...
...Inasmuch as Dr. Noguchi did not go to West Africa until later (he was in New York during August), he could not have furnished the blood for the monkey inoculation, as reported; in fact, he had nothing to do with them, and you may add to this that his leptospira has never been found in West Africa by the Rockefeller investigators. It is also reported that Dr. Noguchi suffered an attack of yellow fever in December, 1927, but if such had been the case, he could not have suffered another, to cause his death, in May, 1928. More likely...
Noguchi discovered that American yellow fever was caused by a tiny organism which he named Leptospira icteroides; was carried by a common lady mosquito, Stegomyia calopus; that guinea pigs could be infected with the organism; that the mosquito would carry the infection from one animal to another ; that a horse serum could be prepared that would cure the disease if administered shortly after the infection. These facts known, the disease was conquered. The same process must be applied to West Africa. For over two years a Com mission of the Rockefeller Foundation has been at work on the problem...
Bacteriologist Noguchi by his experiment has found the invading West African organism to be a more vicious member of the American Leptospira family, is now working on a vaccine...
