Our previous publications and the data presented here provide evidences on the ability of plant-based culture media to optimize the cultivability of rhizobacteria and to support their recovery from plant-soil environments. Compared to the tested chemically-synthetic culture media (e.g. nutrient agar and N-deficient combined-carbon sources media), slurry homogenates, crude saps, juices and powde...

Consumers increasingly use bottled water and home water treatment systems to avoid direct tap water. According to the International Bottled Water Association (IBWA), an industry trade group, 5 billion gallons of bottled water were consumed by North Americans in 2001. The principal aim of this study was to assess the microbial quality of in-house and imported bottled water for human consumption,...

Several Flavobacterium species, comprising a heterogeneous group of gram-negative bacilli that are capable of causing opportunistic infections in humans, have recently been reclassified as Chryseobacterium or Myroides species. Intrinsically resistant to a number of antibiotics, these organisms have been reported to be susceptible to vancomycin and certain other drugs that are normally active ag...

Pseudomonas aeruginosa COL-1 was identified in a blood culture of a 39-year-old-woman treated with imipenem in Marseilles, France, in 1996. This strain was resistant to beta-lactams, including ureidopenicillins, ticarcillin-clavulanic acid, cefepime, ceftazidime, imipenem, and meropenem, but remained susceptible to the monobactam aztreonam. The carbapenem-hydrolyzing beta-lactamase gene of P. a...

BACKGROUND Elizabethkingia meningoseptica is an opportunistic pathogen. Identification of E. meningoseptica based on conventional methods is rather labor- and time-consuming. The information on epidemiological relatedness and microbiological characteristics of E. meningoseptica isolates from central Taiwan was limited. METHODS Forty E. meningoseptica isolates identified by conventional method...

The definition of index goes back to Dixmier [3, 11.1.6]. This notion is important in Representation Theory and also in Invariant Theory. By Rosenlicht’s theorem [12], generic orbits of an arbitrary action of a linear algebraic group on an irreducible algebraic variety are separated by rational invariants; in particular, ind g = tr.degK(g). The index of a reductive algebra equals its rank. Comp...

In this paper, we have proposed new variants of the El-Gamal and the Cramer-Shoup encryption schemes. In our schemes, the anonymity property holds even if each user chooses an arbitrary prime q where |q| = k and p = 2q + 1 is also prime. More precisely, our El-Gamal variants provide anonymity against the chosen-plaintext attack, and our Cramer-Shoup variants provide anonymity against the adapti...
