Die Zellstruktur und die Serologie der Leptospiren

IN VIVO AND IN VITRO OBSERVATIONS OF LEPTOSPIRA POMONA BY ELECTRON MICROSCOPY

“…Leptospires seen in cross section often show the eccentrically located axial filament in close association with the inside surface of the protoplasmic wall. Babudieri (1960) also called attention to the eccentric position of the axial filament. However, the axial filament is also seen closely associated with the exterior surface of the wall of the protoplasmic cylinder.…”

“…Additional morphological details of the three basic structures and their relationship to one another have been forthcoming in recent years as a result of thin sectioning of leptospires. Babudieri (1958Babudieri ( , 1960 has shown conclusively that the axial filament is enveloped by the external membrane and is not located outside of the membrane. Simpson and White (1961) noted that the protoplasmic spiral was tubular in appearance.…”

MORPHOLOGY OF TREPONEMA MICRODENTIUM AS REVEALED BY ELECTRON MICROSCOPY OF ULTRATHIN SECTIONS

“…The majority of these studies have employed shadowed preparations, which can only provide information regarding the external morphology of the microorganisms. Recent reports coupling this technique with partial dissolution of spirochetes have demonstrated that spirochetes consist of three main structures: a protoplasmic cylinder, an axial filament (consisting of one or more fibrils), and an outer envelope (Bradfield and Cater, 1952;Czekalowski and Eaves, 1955;Swain, 1955Swain, , 1957Takeya, Mori, and Toda, 1957;Berger, 1958;Varpholomeeva and Stanislavsky, 1958;Babudieri, 1960).…”

“…In the Leptospira, which have been more extensively studied than other genera, the protoplasmic spiral consists of 12 to 20 coils wound around a single homogeneous axial filament (Babudieri, 1960). The protoplasmic spiral and the axial filament are surrounded by an outer envelope (Swain, 1957).…”
