Brucella is responsible for brucellosis, one of the most common zoonoses worldwide that causes important economic losses in several countries. Increasing evidence indicates that adhesion of Brucella spp. to host cells is an important step to establis

Regulatory network plasticity is a key attribute underlying changes in bacterial gene expression and a source of phenotypic diversity to interact with the surrounding environment. Here, we sought to study the transcriptional circuit of HutC, a regula

Metabolic Control of Virulence Genes in Brucella abortus : HutC Coordinates virB Expression and the Histidine Utilization Pathway by Direct Binding to Both Promoters

Autor: Lucas Bukata, Diego J. Comerci, Gastón Maximiliano Arocena, Rodolfo A. Ugalde, Rodrigo Sieira

Publikováno v: Journal of Bacteriology. 192:217-224

Type IV secretion systems (T4SS) are multicomponent machineries involved in the translocation of effector molecules across the bacterial cell envelope. The virB operon of Brucella abortus codes for a T4SS that is essential for virulence and intracell

Type IV secretion systems (T4SS) are multiprotein structures that direct the translocation of specific molecules across the bacterial cell envelope. As in other bacteria, pathogenicity of the genus Brucella essentially depends on the integrity of the

Identification of the quorum-sensing target DNA sequence and N-Acyl homoserine lactone responsiveness of the Brucella abortus virB promoter

Autor: Rodolfo A. Ugalde, Gastón Maximiliano Arocena, Diego J. Comerci, Rodrigo Sieira

Publikováno v: Journal of bacteriology. 192(13)

VjbR is a LuxR-type quorum-sensing (QS) regulator that plays an essential role in the virulence of the intracellular facultative pathogen Brucella, the causative agent of brucellosis. It was previously described that VjbR regulates a diverse group of
