Pasteurella Pseudotuberculosis 'Swarming Colonies'
at room temperature (70? to 80?F.) it grows in the form of spreading colonies similar to the ' swarming' Proteus colonies. When incubated at 37?C., the growth is limited to the area of the inoculum. At room temperature the growth continues to spread for three days. If a plate that has been incubated at room temperature and shows a spreading form of growth is subsequently incubated at 37?C., the...
متن کاملMetabolism of carbohydrates by Pasteurella pseudotuberculosis.
Cell-free extracts of Pasteurella pseudotuberculosis and P. pestis catalyzed a rapid and reversible exchange of electrons between pyridine nucleotides. Although the extent of this exchange approximated that promoted by the soluble nicotinamide adenine dinucleotide (phosphate) transhydrogenase of Pseudomonas fluorescens, the reaction in the pasteurellae was associated with a particulate fraction...
متن کاملSDS-PAGE and Western blot analysis of somatic and extracellular antigens of Corynebacterium pseudotuberculosis
Different techniques to isolate secreted, cell-surface located and somatic fractions of Corynebacterium pseudotuberculosis have been studied by SDS-PAGE and immunoblotting, by using a pool of sera from naturally infected goats. The secreted antigens were obtained from culture supernatant of the bacteria grown in a chemically defined medium or in Brain Heart Infusion medium. The surface fraction...
متن کاملErythema nodosum due to Pasteurella pseudotuberculosis.
Two children developed erythema nodosum due to Pasteurella pseudotuberculosis. Neither case showed typical signs of P. pseudotuberculosis infection, but this cause was shown by positive agglutination tests. It is suggested that this organism is a more common cause of erythema nodosum than is at present recognized.
متن کاملIntracellular Pasteurella pseudotuberculosis: Multiplication in Cultured Spleen and Kidney Cells.
Pasteurella pseudotuberculosis multiplied within rabbit cells in primary culture. Spleen cells from rabbits were either dispersed mechanically, exposed to the organism immediately after cell preparation, and grown as a pellet or the cells were dispersed enzymatically and grown as a monolayer for 4 to 6 days before the bacteria were introduced. Intracellular multiplication proceeded at a logarit...
