Endosporulation is an ancient bacterial developmental program that culminates with the differentiation of a highly resistant endospore. In the model organism Bacillus subtilis, gene expression in the forespore and in the mother cell, the two cells that participate in endospore development, is governed by cell type-specific RNA polymerase sigma subunits.(More)
Emerging B. cereus strains that cause anthrax-like disease have been isolated in Cameroon (CA strain) and Côte d'Ivoire (CI strain). These strains are unusual, because their genomic characterisation shows that they belong to the B. cereus species, although they harbour two plasmids, pBCXO1 and pBCXO2, that are highly similar to the pXO1 and pXO2 plasmids of(More)
The major protein synthesized in vitro by the ovine thyroid cell line OVNIS 6H is the prothyroid hormone thyroglobulin. Purified from serum-free cell culture media using sucrose gradient centrifugation, the thyroglobulin dimer was analysed for iodine content and observed by electron microscopy. In their usual medium, the OVNIS 6H cells produce a very poorly(More)
