Characterization of lateral flagella of Selenomonas ruminantium.
Selenomonas ruminantium produces a tuft of flagella near the midpoint of the cell body and swims by rotating the cell body along the cell's long axis. The flagellum is composed of a single kind of flagellin, which is heavily glycosylated. The hook length of S. ruminantium is almost double that of Salmonella.
متن کاملFactors affecting lactate and malate utilization by Selenomonas ruminantium.
Lactate utilization by Selenomonas ruminantium is stimulated in the presence of malate. Because little information is available describing lactate-plus-malate utilization by this organism, the objective of this study was to evaluate factors affecting utilization of these two organic acids by two strains of S. ruminantium. When S. ruminantium HD4 and H18 were grown in batch culture on DL-lactate...
متن کاملAmmonia assimilation and glutamate formation in the anaerobe Selenomonas ruminantium.
Selenomonas ruminantium was found to possess two pathways for NH4+ assimilation that resulted in net glutamate synthesis. One pathway fixed NH4+ through the action of an NADPH-linked glutamate dehydrogenase (GDH). Maximal GDH activity required KCl (about 0.48 M), but a variety of monovalent salts could replace KCl. Complete substrate saturation of the enzyme by NH4+ did not occur, and apparent ...
متن کاملBorrelia Outer Membrane Surface Proteins and Transmission Through the Tick
Pathogens of the bacterial genus Borrelia differ from fellow spirochetes, Treponema and Leptospira , in their use of arthropod vectors for transmission between warm-blooded hosts. The agents of relapsing fever, Borrelia recurrentis and Borrelia hermsii , are transmitted by lice and fast-feeding soft ticks, respectively , whereas the Lyme disease spirochete, Borrelia burgdorferi (Bb), is transmi...
متن کاملISOLATION AND PURIFICATION OF MAJOR OUTER MEMBRANE PROTEINS FROM BRUCELLA ABORTUS S-99
Isolation and purification of major outer membrane proteins (OMP) from the cell wall envelope of Brucella abortus S-99 were achieved by sonication, solubilization and membrane fractionation in the presence of non-ionic detergent (Tx-100) and lysozyme treatments, followed by ultracentrifugation. The crude OMP was treated with trypsin to free the preparation from any other protein contaminan...
