High sodium chloride concentrations inhibit staphylococcal enterotoxin C gene (sec) expression at the level of sec mRNA

High sodium chloride concentrations inhibit staphylococcal enterotoxin C gene (sec) expression at the level of sec mRNA.

Expression of the staphylococcal enterotoxin type C gene (sec) is regulated in response to both high NaCl concentrations (osmolarity) and the accessory gene regulator (agr). agr is a global regulator that alters the expression of many genes in Staphylococcus aureus. In this report, we have demonstrated that osmoregulation of sec occurs at the level of mRNA independently of an intact agr allele....

Sequence Variability in Staphylococcal Enterotoxin Genes seb, sec, and sed

Ingestion of staphylococcal enterotoxins preformed by Staphylococcus aureus in food leads to staphylococcal food poisoning, the most prevalent foodborne intoxication worldwide. There are five major staphylococcal enterotoxins: SEA, SEB, SEC, SED, and SEE. While variants of these toxins have been described and were linked to specific hosts or levels or enterotoxin production, data on sequence va...

Multialphabet Arithmetic Coding at 16 MBytes/sec

We present the design and performance of a non-adaptive hardware system for data compression by arithmetic coding. The alphabet of the data source is the full 256-symbol ASCII character set, plus a non-ASCII end-ofle symbol. The key ideas of our system are the non-arithmetic representation of the current interval width, which yields improved coding e ciency in the interval-width update, and a r...
