Evaluation of a voluntary control program for the detection of Bovine Leukemia Virus antibodies based on agar gel immunodiffusion test in dairy farms in Costa Rica
(Universidad Nacional, Costa Rica, 2015-05-02)
A total of 20 farms were analyzed repeatedly during five years using only the agar gel immunodiffusion
test (AGIDT) as part of a voluntary control program of Bovine Leukemia Virus (BLV). After
five years of cleaning up ...
The NS segment of H5N1 avian influenza viruses (AIV) enhances the virulence of an H7N1 AIV in chickens
(Veterinary Research, 2014-01-25)
Some outbreaks involving highly pathogenic avian influenza viruses (HPAIV) of subtypes H5 and H7 were caused by avian-to-human transmissions. In nature, different influenza A viruses can reassort leading to new viruses ...
Neuroinvasion of the highly pathogenic influenza virus H7N1 is caused by disruption of the blood brain barrier in an avian model
(PLOS ONE, 2014-12-15)
Influenza A virus (IAV) causes central nervous system (CNS) lesions in avian and mammalian species, including humans. However, the mechanism used by IAV to invade the brain has not been determined. In the current work, we ...
Presence of Maedi-Visna in Costa Rican sheep flocks
(Small Ruminant Research, 2015-01-22)
A total of 359 sheep serum samples from 15 farms were analyzed for the presence of antibodies against Maedi Visna Virus (MVV) by Enzyme-linked Immunosorbent Assay (ELISA). Additionally, a survey was applied to the sheep ...
Serological detection of viral infections in captive wild cats from Costa Rica
(Veterinary Medicine International, 2011-02-08)
Serum samples from a total of 44 wildcats, 28 margays (Leopardus wiedii), 10 ocelots (Leopardus pardalis), four jaguaroundis (Herpailurus yaguaroundi), one oncilla (Leopardus tigrina), and one jaguar (Panthera onca) were ...
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) ...
