The use of green fluorescent protein as a marker for Brucella vaccines
(Elsevier, 2010-11-04)
La brucelosis es una importante enfermedad de los animales de producción y de la fauna silvestre y una zoonosis mundial. El uso de vacunas eficaces y las correspondientes pruebas de diagnóstico que permiten diferenciar los ...
Human Brucella melitensis infections in southern Vietnam
(European Society of Clinical Microbiology and Infectious Diseases, 2017-06-29)
Brucellosis is a collective term for infections caused by small Gram-negative coccobacilli belonging to genus Brucella. This genus incorporates the well-described animal pathogens Brucella melitensis, Brucella abortus, ...
The role of neutrophils in Brucellosis
(American Society for Microbiology, 2020-10-14)
Brucellosis is a bacterial disease of domestic animals and humans. The pathogenic ability of Brucella organisms relies on their stealthy strategy and their capacity to replicate within host cells and to induce long-lasting ...
The differential interaction of brucella and ochrobactrum with innate immunity reveals traits related to the evolution of stealthy pathogens
(PLOS ONE, 2009-06-16)
Background: During evolution, innate immunity has been tuned to recognize pathogen-associated molecular patterns. However, some a-Proteobacteria are stealthy intracellular pathogens not readily detected by this system. ...
The two-component system BvrR/BvrS regulates the expression of the Type IV secretion system VirB in Brucella abortus
(American Society for Microbiology, 2010-11)
The pathogenesis of Brucella is related to the ability to multiply intracellularly, an event controlled by the
two-component system BvrR/BvrS (TCS BvrRS) and the type IV secretion machinery VirB (T4SS VirB). We have ...
Pathology of striped dolphins (Stenella coeruleoalba) infected with Brucella ceti
(Elsevier Ltd, 2009-10-14)
Seventeen striped dolphins (Stenella coeruleoalba) displaying swimming disorders compatible with neurological syndromes were investigated for Brucella infection. Sixteen dolphins had meningoencephalomyelitis. Serum antibody ...
Serological diagnosis of brucella infections in odontocetes
(American Society for Microbiology, 2009-04-15)
Brucella ceti causes disease in Odontoceti. The absence of control serum collections and the diversity of
cetaceans have hampered the standardization of serological tests for the diagnosis of cetacean brucellosis. Without ...
Neurobrucellosis in stranded dolphins, Costa Rica
(Universidad Nacional, Costa Rica, 2008-09)
Ten striped dolphins, Stenella coeruleoalba, stranded along the Costa Rican Pacifi c coast, had meningoencephalitis and antibodies against Brucella spp. Brucella ceti was isolated from cerebrospinal fl uid of 6 dolphins ...
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 ...
Brucella abortus uses a stealthy strategy to avoid activation of the innate immune system during the onset of infection
(PLOS ONE, 2007-07-18)
Background. To unravel the strategy by which Brucella abortus establishes chronic infections, we explored its early interaction with innate immunity. Methodology/Principal Findings. Brucella did not induce proinflammatory ...
