SPECIFIC AGGLUTINATION OF SPIRILLUM SERPENS

Specific agglutination of Spirillum serpens.

In a previous paper (Pijper et al., 1953) we described our investigations into the nature of the flagellum of Spirillum serpens. In Salmonella somatic, heat-stable or 0 antigens and flagellar, heat-labile or H antigens are recognized and give rise to typical agglutination patterns. H serum causes precipitates on bodies and flagella leading to fortuitous secondary entanglement of flagella, and 0...

Spirillum Fever

found ih the blood in certain diseases are consequences or causes, essential phenomena or epiphenomena; whether, in other words, these diseases are caused by the accidental entrance into the blood of the germs of these organisms and their development there, or whether the organisms are mere accidents of the malady, forms of life due to changes in organic fluids in which they find, owing to thes...

Ultrastructure of a magnetotactic spirillum.

The ultrastructure of a magnetotactic bacterium (strain MS-1) was examined by transmission, scanning, and scanning-transmission electron microscopy. The organism resembled other spirilla in general cell morphology, although some differences were detected at the ultrastructural level. Electron-dense particles within magnetotactic cells were shown by energy-dispersive X-ray analysis to be localiz...

Ultracentrifugation and Cytology of Spirillum

During the past few years the authors have been interested in studying the effects of high centrifugal force upon the structure of various types of cells in both plants and animals (Beams and King, 1940). In the course of these investigations a large flagellated bacterium, Spirillum volutans, appeared among our cultures of protozoa. Because of its large size it was thought that this organism mi...
