Formation of granular structures by leptospirae as revealed by the electron microscope.

چکیده
The formation of granules in leptospirae was noticed many years ago, but there is still no agreement as to their biological sigificance. Some authors are inclined to interpret them as products of disintegration of dead or degenerated organisms (Marchoux and Couvy, 1913; Gonder and Gross, 1919; Uhlenhuth and Fromme, 1930) while others consider that they play a definite role in the life-cycle of the organisms (Sergent and Foley, 1908; Balfour, 1911, 1912; Fantham, 1911; Meirowsky, 1914; Nicolle and Blanc, 1914; Leishman, 1918, 1920; Leipold, 1926; Bessemans et al., 1942; Gastinel and Mollinedo, 1942; Jakob, 1949). Granular structures develop spontaneously in aging cultures (Babudieri, 1949), but some workers (Timmerman, 1927; Herreweghe, 1943; Babudieri, 1949) have produced granulation artificially in young cultures by means of physical and chemical methods (cooling, heating, homologous antiserum, sodium taurocholate). The present paper is concerned with those granules which are formed naturally.
