The morphology and cultural characteristics of bacteria of the Simonsiella genus isolated from erosions of oral mucosa are reported here. Direct microscopic examination of smeared oral swabs and the consequent selection of suitable culturing procedures and media are compulsory for recovering Simonsiella microorganisms from clinical specimens in routine work.

Rod-shaped bacteria typically elongate and divide by transverse fission. However, several bacterial species can form rod-shaped cells that divide longitudinally. Here, we study the evolution of cell shape and division mode within the family Neisseriaceae, which includes Gram-negative coccoid and rod-shaped species.

View Article and Find Full Text PDFThe morphology and ultrastructure of the aerobic, Gram-negative multicellular-filamentous bacteria of the genus simonsiella were investigated by scanning and transmission electron microscopy. The flat, ribbon-shaped, multicellular filaments show dorsal-ventral differentiation with respect to their orientations to solid substrata. The dorsal surface, orientated away from the substrate, is convex and possesses an unstructured capsule.
