Brucella abortus transits through the autophagic pathway and replicates in the endoplasmic reticulum of nonprofessional phagocytes
(American Society for Microbiology, 1988-09-01)
Brucella abortus is an intracellular pathogen that replicates within a membrane-bounded compartment. In
this study, we have examined the intracellular pathway of the virulent B. abortus strain 2308 (S2308) and the
attenuated ...

Brucella-Salmonella lipopolysaccharide chimeras are less permeable to hydrophobic probes and more sensitive to cationic peptides and EDTA than are their native Brucella sp. counterparts
(American Society for Microbiology, 1996-08-12)
A rough (R) Brucella abortus 45/20 mutant was more sensitive to the bactericidal activity of polymyxin B and lactoferricin B than was its smooth (S) counterpart but considerably more resistant than Salmonella montevideo. ...
Characterization of Brucella abortus and Brucella melitensis native haptens as outer membrane O-type polysaccharides independent from the smooth lipopolysaccharide
(American Society for Microbiology, 1996)
Brucella native haptens (NHs) extracted with hot water from smooth (S)- type B. abortus and B. melitensis were purified to high levels of serological activity and compared with the polysaccharide obtained by acid hydrolysis ...
Characterization of Brucella abortus lipopolysaccharide macrodomains as mega rafts
(Blackwell Science, 2005-09-28)
The lipopolysaccharides (LPS) of intracellular Proteobacteria such as Brucella, Chlamydia, Legionella and Rickettsia, have properties distinct from enterobacterial LPSs. These properties include deficient LPS induction of ...
Positivity of Lawsonia intracellularis in seven regions of Costa Rica diagnosed by porcine fecal samples using Real time PCR
(Anatomical Society, 2019-08)
Lawsonia intracellularis is an obligate
intracellular, motile, curved, gram-negative
bacterium that resides freely within the apical
cytoplasm of infected intestinal enterocytes
(Pusterla & Gebhart, 2013). Europe, Asia ...
In search of a bacterial spedes definition
(Universidad de Costa Rica., 1997)
The bacterial species concept was examined within the framework of plant and animal associated a-2 proteobacteria, taking into consideration the phylogenetic, taxonomic and biological approaches as well as the microbiologists' ...
MyD88, but not Toll-Like receptors 4 and 2, Is required for efficient clearance of Brucella abortus
(American Society for Microbiology, 2005-08)
It is not clear how the host initially recognizes and responds to infection by gram-negative pathogenic
Brucella spp. It was previously shown (D. S. Weiss, B. Raupach, K. Takeda, S. Akira, and A. Zychlinsky, J.
