The sigma factor RpoS is required for stress tolerance and environmental fitness of Pseudomonas fluorescens Pf-5.
Many micro-organisms exist in natural habitats that are subject to severe or dramatically fluctuating environmental conditions. Such is the case for bacteria inhabiting plant surfaces, where they are exposed to UV irradiation, oxygen radicals, and large fluctuations in temperature and moisture. This study focuses on the role of RpoS, a central regulator of stationary-phase gene expression in ba...

متن کاملIdentification of "Cronobacter" spp. (Enterobacter sakazakii).
A taxonomic reclassification of the neonatal pathogen Enterobacter sakazakii to consist of five species within a new genus, "Cronobacter," has recently been proposed. The correct identification of these organisms is important to clinicians. Therefore, using 312 Enterobacteriaceae, including 210 "Cronobacter" strains, the reliabilities of biochemical and genetic confirmation tests were investiga...
متن کاملGenes involved in yellow pigmentation of Cronobacter sakazakii ES5 and influence of pigmentation on persistence and growth under environmental stress.
Cronobacter spp. are opportunistic food-borne pathogens that are responsible for rare but highly fatal cases of meningitis and necrotizing enterocolitis in neonates. While the operon responsible for yellow pigmentation in Cronobacter sakazakii strain ES5 was described recently, the involvement of additional genes in pigment expression and the influence of pigmentation on the fitness of Cronobac...
متن کاملSupersize me: Cronobacter sakazakii phage GAP32.
Cronobacter sakazakii is a Gram-negative pathogen found in milk-based formulae that causes infant meningitis. Bacteriophages have been proposed to control bacterial pathogens; however, comprehensive knowledge about a phage is required to ensure its safety before clinical application. We have characterized C. sakazakii phage vB_CsaM_GAP32 (GAP32), which possesses the second largest sequenced pha...
