Intracellular adaptation of Brucella abortus
(Universidad Nacional, Costa Rica, 2009-03)
Macrophages were infected with virulent B. abortus strain 2308 or attenuated strain 19. Intracellular bacteria were recovered at different times after infection and their proteomes compared. The virulent strain initially ...
BvrR/BvrS-controlled outer membrane proteins Omp3a and Omp3b are not essential for Brucella abortus virulence
(American Society for Microbiology, 2007-07-30)
The Brucella abortus two-component regulatory system BvrR/BvrS controls the expression of outer membrane proteins (Omp) Omp3a (Omp25) and Omp3b (Omp22). Disruption of bvrS or bvrR generates avirulent mutants with altered ...
The two-component system BvrR BvrS essential for Brucella abortus virulence regulates the expression of outer membrane proteins with counterparts in members of the Rhizobiaceae
(Proceedings of the National Academy of Sciences, 2002-09-17)
The Brucella BvrR/BvrS two-component regulatory system is homologous to the ChvI/ChvG systems of Sinorhizobium meliloti and Agrobacterium tumefaciens necessary for endosymbiosis and pathogenicity in plants. BvrR/BvrS ...
Purification of intracellular bacteria: isolation of viable Brucella abortus from host cells
(Springer Science, Business Media Nueva York, 2014, 2014)
The pathogenesis of brucellosis depends on the ability of bacteria from the genus Brucella to invade and
replicate within animal cells. To understand the molecular pathways used by Brucella spp. to reach its
intracellular ...
Detección y genotipificación de rotavirus bovino y porcino en Costa Rica
(Universidad Nacional, Costa Rica, 2007-10)
Treinta y ocho muestras fecales de bovinos con diarrea neonatal, positivas
a rotavirus grupo A por inmunocromatografía y electroforesis en gel de
poliacrilamida (PAGE) fueron analizadas mediante reverso transcripción y ...
In vivo animal models confrm an increased virulence potential and pathogenicity of the NAP1/RT027/ST01 genotype within the Clostridium difcile MLST Clade 2
(BioMed Central, 2020-09-22)
Background: Based on MLST analyses the global population of C. difcile is distributed in eight clades, of which
Clade 2 includes the “hypervirulent” NAP1/RT027/ST01 strain along with various unexplored sequence types ...
Regulation of Brucella virulence by the two-component system BvrR/BvrS
(Elsevier B.V., 2002-12-20)
The Brucella BvrR/BvrS two-component regulatory system is highly similar to the regulatory and sensory proteins of Sinorhizobium and Agrobacterium necessary for endosymbiosis and pathogenicity in plants, and very similar ...
