Specific Mutations in the PB2 Protein of Influenza A Virus Compensate for the Lack of Efficient Interferon Antagonism of the NS1 Protein of Bat Influenza A-Like Viruses
(2018-03-14)
Recently, two new influenza A-like viruses have been discovered in bats, A/little yellow-shouldered bat/Guatemala/060/2010 (HL17NL10) and A/flat-faced bat/Peru/033/2010 (HL18NL11). The hemagglutinin (HA)-like (HL) and ...
Detection of Dirofilaria immitis and other arthropod-borne filarioids by an HRM real-time qPCR, blood-concentrating techniques and a serological assay in dogs from Costa Rica
(2015)
Background: Canine filarioids are important nematodes transmitted to dogs by arthropods. Diagnosis of canine
filariosis is accomplished by the microscopic identification of microfilariae, serology or PCR for filarial-DNA. ...
Isolation and molecular characterization of Acanthamoeba and Balamuthia mandrillaris from combination shower units in Costa Rica
(2014-08-19)
Free living amoebae (FLA) are ubiquitous protozoa, which may behave as parasites under certain conditions. Four genera are recognized as causal agents of infections in humans and animals: Naegleria, Sappinia, Acanthamoeba ...
First Report of the Isolation and Molecular Characterization of Rickettsia amblyommii and Rickettsia felis in Central America
(2011-10-05)
During 2010, 15 adult ticks, identified as Amblyomma cajennense, were collected from horses in Cahuita and Turrialba districts, whereas 7 fleas, identified as
Ctenocephalides felis, were collected from a dog in San Jose ...
Depletion of complement enhances the clearance of Brucella abortus in mice
(2018)
Brucellosis is a bacterial disease of animals and humans. Brucella abortus
barely activates the innate immune system at the onset of infection, and this
bacterium is resistant to the microbicidal action of complement. ...
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 ...
