Show vv ISOLATING GERM OF SPOTTED FEVER. When Dr. John D. Carnahan was alive, he informed the writer he had associated spotted fever with the woodtick. That was long prior to In-' In-' vestigations pursued by Dr. Howard Rlcketts of the government service Yesterday, in Salt Lake, Dr. L. D Fricks, of the United States bureau of health, announced a further step forward in controlling spotted fever, with isolating of the germ. Dr Fricks classified the germ6 as a low-grade protozoan, comparatively large from a microscopic standpoint, bright red in color, surrounded by dark blue protoplasm, found it in the blood of animals affected by spotted fever. He also knows it exists in the mouth parts of the ticks which carry the spotted fever. Dr Fricks said he made the discovery discov-ery while working with some serum which had become infested with a foreign for-eign coccus To separate that coccus from the serum he said he diluted the serum one to ten and subjected it to a process known as centrifusion, after which he found he had a serum the upper parts of which produced no effect ef-fect on animals, but the sediment in the tube produced spotted fever whenever when-ever Injected. In that sediment he isolated the germ which causes the disease. That germ Is what carries the disease In the veins of its victims. nn |
