SYNOPSIS. Dactylosoma is a genus of blood protozoa which undergo schizogony, without producing pigment, in the red cells of the lower vertebrates, especially amphibia. The best known species is D. ranarum, but even for this species the life cycle, except as it occurs in the erythrocyte, and the vector remain unknown. Study of slides from the blood of

The genus Apodachlya Pringsheim is revised and restricted to three species, of which descriptions and illustrations are given. On the basis of a study of pure cultures, it is concluded that A. punctata Minden is identical with A. brachynema (Hildebrand) Pringsheim.

, 1981 The bacteria of the genus Gallionella belong to the so-called “iron bacteria”, which achieved their theoretical importance after Winogradsky (1888, 1922) postulated his conception of chemolithotrophy for these organisms. These bacteria also have practical significance: They clog drains, water pipes, and wells with deposits of iron oxide compounds.

The first description of a bacterium that produced twisted bundles of thin filaments which contained oxidized iron was given by Cholodny (1924). He called this organism Leptothrix trichogenes, the filament-producing Leptothrix. The flexible bacterium was observed in a water basin next to the river Dnjepr near Kiew, Russia. Its cells (diameter approx. 0.

Light-microscopic investigation of the microorganisms in the hypolimnion shows, in many lakes, the presence of a highly diverse population of bacteria. Here, most of the recognizable forms have never been cultured and many of them have not even been reported.
