Release of the type I secreted α-haemolysin via outer membrane vesicles from Escherichia coli (2006)

Balsalobre, Carlos, Silván, José Manuel, Berglund, Stina, Mizunoe, Yoshimitsu, Uhlin, Bernt Eric, Nyunt Wai, Sun

The α-haemolysin is an important virulence factor commonly expressed by extraintestinal pathogenic Escherichia coli. The secretion of the α-haemolysin is mediated by the type I secretion system and...

Alterations in Protein Expression Caused by the hha Mutation in Escherichia coli: Influence of Growth Medium Osmolarity

Balsalobre, Carlos, Johansson, Jörgen, Uhlin, Bernt Eric, Juárez, Antonio, Muñoa, Francisco J.

The Hha protein belongs to a new family of regulators involved in the environmental regulation of virulence factors. The aim of this work was to study the effect of the hha mutation on the overall...

Transcriptional Analysis of the sfa Determinant Revealing Multiple mRNA Processing Events in the Biogenesis of S Fimbriae in Pathogenic Escherichia coli

Balsalobre, Carlos, Morschhäuser, Joachim, Jass, Jana, Hacker, Jörg, Uhlin, Bernt Eric

Among the virulence factors present in pathogenic extraintestinal Escherichia coli strains, expression of fimbrial adhesins is necessary for attachment to the host tissues and subsequent...

Temperature-Dependent Conjugative Transfer of R27: Role of Chromosome- and Plasmid-Encoded Hha and H-NS Proteins

Forns, Núria, Baños, Rosa C., Balsalobre, Carlos, Juárez, Antonio, Madrid, Cristina

IncHI plasmids encode multiple-antibiotic resistance in Salmonella enterica serovar Typhi. These plasmids have been considered to play a relevant role in the persistence and reemergence of this...

Cyclic AMP-Dependent Osmoregulation of crp Gene Expression in Escherichia coli

Balsalobre, Carlos, Johansson, Jörgen, Uhlin, Bernt Eric

We have found that the cyclic AMP (cAMP) receptor protein (CRP)-cAMP regulatory complex in Escherichia coli is subject to osmoregulation at the level of crp gene expression. This osmoregulation was...

Type 1 Fimbriae, a Colonization Factor of Uropathogenic Escherichia coli, Are Controlled by the Metabolic Sensor CRP-cAMP

Müller, Claudia M., Åberg, Anna, Straseviçiene, Jurate, Emődy, Levente, Uhlin, Bernt Eric, Balsalobre, Carlos

Type 1 fimbriae are a crucial factor for the virulence of uropathogenic Escherichia coli during the first steps of infection by mediating adhesion to epithelial cells. They are also required for the...

Similar and Divergent Effects of ppGpp and DksA Deficiencies on Transcription in Escherichia coli▿ †

Åberg, Anna, Fernández-Vázquez, Jorge, Cabrer-Panes, Juan David, Sánchez, Alex, Balsalobre, Carlos

The concerted action of ppGpp and DksA in transcription has been widely documented. In disparity with this model, phenotypic studies showed that ppGpp and DksA might also have independent and...
