Urea restrains swarming of Proteus mirabilis.
In veterinary microbiology, samples taken from ears or wounds of dogs and cats are often contaminated by Proteus mirabilis. P. mirabilis swarms over the entire plate culture of these samples, making it almost impossible to isolate single colonies of other bacterial species present in the sample. Various compounds, like p-nitrophenyl glycerin and activated charcoal, abolish the swarming of Prote...
متن کاملInhibition of Proteus Swarming by Nucleic Acid
was attributable to the DNA (sperm deoxyribonucleic acid, Lot no. 1701, Nutritional Biochemicals Corp., Cleveland, Ohio) which had been added to Tryptose Agar (Difco) because swarming developed freely on the unsupplemented Tryptose Agar. This observation added an exceptional compound to the numerous substances which are known to interfere with the ability of Proteus sp. to swarm on agar media. ...
متن کاملRegulation of the swarming inhibitor disA in Proteus mirabilis.
The disA gene encodes a putative amino acid decarboxylase that inhibits swarming in Proteus mirabilis. 5' rapid amplification of cDNA ends (RACE) and deletion analysis were used to identify the disA promoter. The use of a disA-lacZ fusion indicated that FlhD(4)C(2), the class I flagellar master regulator, did not have a role in disA regulation. The putative product of DisA, phenethylamine, was ...
متن کاملClinical evaluation of the essential oil of Pelargonium graveolens for the treatment of denture stomatitis
BACKGROUND Natural products are proved to play a good role as an alternative to synthetic chemicals in clinical conditions. Previous studies showed that Pelargonium graveolens has anti-inflammatory and antifungal activity against Candida albicans. The aim of this study was to evaluate the efficacy of essential oil of Pelargonium graveolens in the treatment of denture stomatitis. MATERIALS AND...
متن کاملThe Dienes phenomenon: competition and territoriality in Swarming Proteus mirabilis.
When two different strains of swarming Proteus mirabilis encounter one another on an agar plate, swarming ceases and a visible line of demarcation forms. This boundary region is known as the Dienes line and is associated with the formation of rounded cells. While the Dienes line appears to be the product of distinction between self and nonself, many aspects of its formation and function are unc...
