SARS-CoV-2 genomic surveillance in Costa Rica: Evidence of a divergent population and an increased detection of a spike T1117I mutation
(2021)
Genome sequencing is a key strategy in the surveillance of SARS-CoV-2, the virus responsible for the COVID-19 pandemic. Latin America is the hardest-hit region of the world, accumulating almost 20% of COVID-19 cases ...
Heterologous hyperimmune polyclonal antibodies against SARS-COV-2: A broad coverage, affordable, and scalable potential immunotherapy for Covid-19
(2021-09)
The emergence and dissemination of the severe acute respiratory syndrome coronavirus 2
(SARS-CoV-2) and the resulting COVID-19 pandemic triggered a global public health crisis.
Although several SARS-CoV-2 vaccines have ...
Molecular Characterization of Two Major Dengue Outbreaks in Costa Rica
(2016-07)
Dengue virus (DENV) (Flavivirus, Flaviviridae) is a reemerging arthropod-borne virus with a worldwide
circulation, transmitted mainly by Aedes aegypti and Aedes albopictus mosquitoes. Since the first detection of its ...
Neotropical primary bat cell lines show restricted dengue virus replication
(2017-02)
Dengue is the most widespread arboviral disease affecting humans. Bats are recognized carriers of emerging viral zoonoses and have been proposed as dengue reservoirs, since RNA/NS1 and/or antiviral antibodies have been ...
Neotropical bats that co-habit with humans function as dead-end hosts for dengue virus
(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 ...
High Efficacy of Therapeutic Equine Hyperimmune Antibodies Against SARS-CoV-2 Variants of Concern
(2021)
SARS-CoV-2 variants of concern show reduced neutralization by vaccine-induced and
therapeutic monoclonal antibodies; therefore, treatment alternatives are needed. We
tested therapeutic equine polyclonal antibodies (pAbs) ...
