Brucellosis in mammals of Costa Rica: An epidemiological survey
(PLOS ONE, 2017-08-09)
Brucellosis has been an endemic disease of cattle and humans in Costa Rica since the
beginning of XX century. However, brucellosis in sheep, goats, pigs, water buffaloes, horses
and cetaceans, has not been reported in ...
Pathological Studies and Postmortem Computed Tomography of Dolphins with Meningoencephalomyelitis and Osteoarthritis Caused by Brucella ceti
(MDPI, 2022-05-09)
Cetacean neurobrucellosis is a common cause of strandings in Costa Rica diagnosed by
serology, bacteriology, and histopathology. Pathological studies were performed on 18 dolphins.
Twelve were scanned by postmortem ...
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 ...
Comparison of the antibody response in adult cattle against different epitopes of Brucella abortus lipopolysaccharide
(Blackwell, 2001)
The comparison of serological responses in a sample of adult, vaccinated and held-infected bovines with Brucella abortus is reported. Indirect enzyme immunoassav (EIA) titration curves and Western blotting tests for ...
Public 2308W annotation
(Universidad Nacional, Costa Rica, 2016-09-29)
This is an editable version of B. abortus 2308W. The aim of this document is to provide a simple mechanism for updates in genes annotation.
Extensive Cell Envelope Modulation Is Associated with Virulence in Brucella abortus
(American Chemical Society, 2007-08-03)
Brucella virulence is linked to components of the cell envelope and tightly connected to the function of
the BvrR/BvrS sensory-regulatory system. To quantify the impact of BvrR/BvrS on cell envelope proteins,
we performed ...
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.
Immunol. ...
Hallazgos anatomopatológicos en virtopsia, necropsia, bacteriología e histopatología del sistema nervioso central de cetáceos encallados en las playas de Costa Rica durante el periodo 2017-2021
(Universidad Nacional, Costa Rica, 2021-10-08)
La fauna de cetáceos en Costa Rica incluye una estimación de 30 especies,
esta biodiversidad representa el 33% de las especies de cetáceos del mundo y, por lo
tanto, anualmente se reportan encallamientos de cetáceos a ...
