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 ...
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 ...
Neotropical bats that co-habit with humans function as dead-end hosts for dengue virus
(Public Library of Science (PLOS), 2017-05-18)
Several studies have shown Dengue Virus (DENV) nucleic acids and/or antibodies present
in Neotropical wildlife including bats, suggesting that some bat species may be susceptible
to DENV infection. Here we aim to elucidate ...
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) ...
Seroprevalence of porcine reproductive and respiratory syndrome virus on swine farms in a tropical country of the Middle Americas: the case of Costa Rica
(Springer Nature, 2021-08-18)
Porcine reproductive and respiratory syndrome virus (PRRSV) causes signifcant economic losses to the swine industry worldwide. Little is known regarding the epidemiology of this infection in tropical countries. To address ...
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 ...
Seroprevalence and molecular characterization of ferlavirus in captive vipers of Costa Rica
(American Association of Zoo Veterinarians, 2017-06-01)
Abstract: Ferlaviruses (FV, previously referred to as ophidian paramyxoviruses, OPMV), are enveloped viruses with a negative-strand RNA genome, affecting snakes in captivity worldwide. Infection is characterized by respiratory ...
