Book excerpt: Excerpt from Collected Studies on Typhus Several observers and writers have called attention to the close clinical resemblance of Rocky Mountain spotted fever to typhus. One of us having seen typhus fever in England, and later the spotted fever in Montana, was also struck by the clinical similarity of the two diseases. Typhus fever being one of the quarantinable diseases under the regulations of the Treasury Department, it seemed desirable both on theoretical and practical grounds to take up the study of typhus fever in Mexico in order to determine whether the two diseases are really identical, particularly as the 'work of Ricketts had developed a basis for the identification of the Rocky Mountain disease. Ricketts has shown that Rocky Mountain spotted fever has a definite clinical course in certain animals, particularly guinea pigs and monkeys, in which it also produces characteristic anatomical lesions. He has shown that in the guinea pig, after intraperitoneal inoculation of blood of spotted fever, there appears in from two to five days a dis tinct rise in the temperature of the animal. The fever continues to rise for two or three days, after which it maintains itself at about the level which it has attained for two or three days longer. At the end of this time the animal either dies or the fever begins to subside. The obj edtive signs of the infection are a roseolar eruption, with hemorrhage into and frequently gangrene of the external genitals. At necropsy the most striking features are a greatly enlarged spleen and swollen and hemorrhagic lymph nodes. With these facts in mind, we took up the study of typhus as it presents itself in Mexico City. Our observations of the disease in'the Hospital General bring out certain definite clinical differences be tween this disease and the Rocky Mountain fever. These differences we will discuss in a later paper. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
