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...
متن کاملCell organization and ultrastructure of a magnetotactic multicellular organism.
Magnetotactic multicellular aggregates and many-celled magnetotactic prokaryotes have been described as spherical organisms composed of several Gram-negative bacteria capable to align themselves along magnetic fields and swim as a unit. Here we describe a similar organism collected in a large hypersaline lagoon in Brazil. Ultrathin sections and freeze fracture replicas showed that the cells are...
متن کاملOpposite and Coordinated Rotation of Amphitrichous Flagella Governs Oriented Swimming and Reversals in a Magnetotactic Spirillum.
UNLABELLED Current knowledge regarding the mechanism that governs flagellar motor rotation in response to environmental stimuli stems mainly from the study of monotrichous and peritrichous bacteria. Little is known about how two polar flagella, one at each cell pole of the so-called amphitrichous bacterium, are coordinated to steer the swimming. Here we fluorescently labeled the flagella of Mag...
متن کاملSpontaneous Infection of Guinea-Pigs with a Spirillum, Presumably Spirillum Minus Carter, 1887
McCluskie (1930), Robertson (1930), Francis (1936), and Knowles, Das Gupta and Sen (1936) have noted the occurrence of Spirillum minus in the naturally-infected mouse, Mus musculus. The last-named workers cited an incident in which a wrong diagnosis of rat-bite fever was established on the basis of discovery of spirilla in a white mouse inoculated with the blood of a patient suffering from prol...
