CHROMagar Staph aureus (CSAM) (CHROMagar Microbiology, Paris, France) is a new chromogenic medium designed to enable detection of colonies of Staphylococcus aureus by their pink color. A total of 775 specimens were cultured in parallel on CHROMagar Staph aureus and conventional media. Among the 267 S. aureus strains recovered on at least one medium, 263 were isolated on CSAM medium (sensitivity...

Untargeted mutation and delayed mutation are features of radiation-induced genomic instability and have been studied extensively in tissue culture cells. The mouse pink-eyed unstable (p(un)) mutation is due to an intragenic duplication of the pink-eyed dilution locus and frequently reverts back to the wild type in germ cells as well as in somatic cells. The reversion event can be detected in th...

Low frequency noise characterisation of 0.12 μm SOI CMOS technology was performed for Partially and Fully Depleted N-MOSFETs. Static performances are first presented, then we address the drain current fluctuations in both linear and saturation regimes. Taking into consideration the usually admitted 1/f noise models in MOS devices and their applicability in our case, we finally point out the enh...

Some strains of S. marcescens are capable of producing pigment, the intensity of which ranges from dark red to pale pink, depending on the age of the colonies. The pigment can be present after incubation at room temperature but usually disappears after subculturing. The pigment was extractred by 1902 and named "prodigiosin" . Serratia marcescens has a predilection for growth on foodstuffs, espe...

Sash (Wsh), a viable and fully fertile allele of the dominant spotting (W) locus (Lyon & Glenister, 1982) has been used in a modified test system to investigate the site of gene expression at the pink-eyed dilution (p) locus. Reciprocal recombinant epidermal@dermal skin grafts were constructed from 13-day embryonic skin of p and Wsh homozygotes. Thus in the reciprocal experiments pink-eyed dilu...

Strain K-20(T), a Gram-negative, nonmotile, nonspore-forming and strictly aerobic coccobacillus, which produces a pale pink pigment (R2A agar medium, 30℃, seven days) was isolated from a sample of biofilm obtained from a cooling tower in Tokyo, Japan. A phylogenetic analysis of the 16S rRNA partial gene sequences (1,439 bp) showed that the strain (accession number: AB297501) was related to Rose...

Here, we present the draft genome of Haladaptatus sp. strain R4, a halophilic archaea that produces an orange-pink pigment and is capable of growing in a wide salinity range. The genome assembly shows genes for arsenic resistance, siderophore production, trehalose and glycine betaine biosynthesis, uptake and transporters of sodium, potassium, and chloride ions.
