From: Morphological analysis of the sheathed flagellum of Brucella melitensis
Visualization of flagella. Ryu staining of B. melitensis (A) C. crescentus (B) observed by phase-contrast microscopy. The samples were treated by the Ryu staining method as described in Materials and Methods. A flagellated bacterium is enlarged in a dotted square. (C) Negative-staining EM images of the sheathed polar flagellum of B. melitensis stained with uranyl acetate 2% and labeled with anti-LPS antibody conjugated to ± 15 nm gold particles. Bar, 500 nm.
