A Sinorhizobium meliloti and Agrobacterium tumefaciens ExoR ortholog is not crucial for Brucella abortus virulence
(PLOS ONE, 2021-08-13)
Brucella is a facultative extracellular-intracellular pathogen that belongs to the Alphaproteo-
bacteria class. Precise sensing of environmental changes and a proper response mediated
by a gene expression regulatory ...
First complete coding sequence of a Venezuelan Equine Encephalitis Virus Strain Isolated from an Equine Encephalitis case in Costa Rica
(Microbiol Resour Announc, 2019-09-05)
The first complete coding sequence of the Venezuelan equine encepha-
litis virus IE, isolated from a Costa Rican mare with severe encephalitis, was con-
firmed by histological and viral whole-genome analyses. The isolated ...
Comparison of competitive enzyme-linked immunosorbent assay and serum neutralization test for the detection of antibodies to vesicular stomatitis virus (New Jersey and Indiana serotypes) in equines from Costa Rica
(Universidad Nacional, Costa Rica, 2014)
A competitive enzyme-linked immunosorbent assay (c-ELISA) was compared to the serum
neutralization test (SNT) for the detection of antibodies against vesicular stomatitis virus, New Jersey
(VSV-NJ) and Indiana (VSV-IN) ...

Serosurvey of nonhuman primates in Costa Rica at the human–wildlife interface reveals high exposure to flaviviruses
(Multidisciplinary Digital Publishing (MDPI), 2021-06-15)
Arthropod-borne viruses belonging to the flavivirus genus possess an enormous relevance
in public health. Neotropical non-human primates (NPs) have been proposed to be susceptible to
flavivirus infections due to their ...
A two-component regulatory system playing a critical role in plant pathogens and endosymbionts is present in Brucella abortus and controls cell invasion and virulence
(Blackwell Science, 1998-04-08)
Two mutants showing increased sensitivity to polycations and surfactants were obtained by transposon mutagenesis of virulent Brucella abortus 2308 Nal(r). These mutants showed no obvious in vitro growth defects and produced ...

(AAVLD, 2002-05-01)
A competitive enzyme-linked immunosorbent assay (C-ELISA) for the detection of antibodies against
vesicular stomatitis virus New Jersey (VSV-NJ) and vesicular stomatitis virus Indiana (VSV-IN) was compared with
the serum ...
Prevalence of Psittacine Beak and Feather Disease Virus and Avian Polyomavirus in Captivity Psittacines from Costa Rica
(Scientific Research, 2013-08)
Psittacine beak and feather disease virus (PBFDV) and avian polyomavirus (APV) are the most common viral diseases in psittacine birds, both affecting feathers and physical appearance of birds. Between 2005 and 2009, a total ...

Neutralizing antibodies against vesicular stomatitis viruses (serotypes New Jersey and Indiana) in horses in Costa Rica
(AAVLD, 2002-09-01)
Serum samples were collected from domestic horses in 4 different regions of Costa Rica to detect
antibodies against vesicular stomatitis viruses, serotypes New Jersey (VSV-NJ) and Indiana (VSV-IN). A total
of 214 samples ...
