The etiologic relation of fusiform bacilli and the associated spiral organisms now commonly called spirochetes, to the diseases in which they are found is difficult of demonstration on account of the presence of streptococci and other bacteria in cultures; and then the bacilli and spirals so far isolated usually lack virulence for animals. The strongest evidence of an etiologic relation has been furnished by the examination of sections of the involved tissues. Many observers have demonstrated these organisms in noma,' at the line of advancing necrosis, where they are found in great numbers, apparently pure, and also in small numbers in the unaltered tissue. The spiral forms have generally been observed in the living tissue in advance of the bacilli (Perthes," Buday" and Ellermann") . Vincent," Krebs," and Gross' have studied sections of the ulcerĀ­ membranous lesions of the tonsils, and Ellermann" of the uvula. They observed a variety of bacteria, especially cocci in the external necrotic layer; in the middle zone between necrotic and normal tissue a large number of fusiform bacilli, often in TI - The Microscopic Appearances in Ulceromembranous Tonsillitis (Vincent's Angina) JF - The Journal of Infectious Diseases DO - 10.1093/infdis/25.2.132 DA - 1919-09-01 UR - https://www.deepdyve.com/lp/oxford-university-press/the-microscopic-appearances-in-ulceromembranous-tonsillitis-vincent-s-CEetBrJ458 SP - 132 EP - 134 VL - 25 IS - 2 DP - DeepDyve ER -
