Properties of Proteus mirabilis and Providence spheroplasts.
Proteus mirabilis strain I 3 and Providence strain NCTC 92 I I were converted to osmotically sensitive spheroplasts by growth in the presence of penicillin or glycine in sucrose-supplemented or unsupplemented medium. Lysazyme in the presence of tris and ethylenediaminetetra-acetic acid (EDTA) converted both these strains to spheroplasts. Penicillin spheroplasts could be stabilized with sucrose,...
متن کاملBiochemical investigation of Providence strains and their relationship to the Proteus group.
The search for the possible causative agents of acute infective diarrhoea in infants and children has brought to light a great number of groups and strains of enteric bacteria other than Salmonella and Shigella. None of them can yet be incriminated with certainty as being pathogenic. The problem of potential or conditioned pathogenicity cannot be solved without a more comprehensive knowledge of...

متن کاملMotility, Swarming, and Growth of Proteus
Kopp, RIUDOLF (Hygiene-Institut der Universitat, Freiburg, Germany), AND JOHANNES MULLER. Effects of related anionic detergents on flagellation, motility, swarming, and growth of Proteus. Appl. Microbiol. 13:950-955. 1965.-The effects of a series of sodium alkyl sulfates (C4 to C16) on flagellation, motility, swarming, and growth of Proteus were examined. The concentrations of the various sodiu...
متن کاملMeasurement of Proteus cell motility during swarming.
The motilities of Proteus long forms during swarming on agar were measured on cells transferred to liquid suspension. During concentric-ring formation on solid medium, when the edge of the swarm was advancing slowly or had stopped, the velocity of long-form motility was low. When the colony was spreading rapidly, long-form velocitywas relatively high. This periodic variation in cell velocity, w...
