Bioprospección de beta-glucosidasas novedosas a partir de metagenomas obtenidos de intestinos de escarabajos pasálidos de Costa Rica y respiraderos hidrotermales de la Isla Vulcano en Italia
(2019-10)
La aplicación de tecnologías que permitan el establecimiento de biorrefinerías constituye una alternativa interesante que busca incentivar una menor dependencia en el uso de combustibles fósiles y generar productos de valor ...
Enterococci as a key parameter for water quality index: Purires River, Costa Rica
(2018)
This study used the Canadian Water Quality Index (CWI) to characterize water sampled at three points within the Purires River micro basin, Costa Rica. The first sampling point is located in a high zone with domestic ...
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. ...
Modulation of the Susceptibility of Human Erythrocytes to Snake Venom Myotoxic Phospholipases A2: Role of Negatively Charged Phospholipids as Potential Membrane Binding Sites
(2001-07-01)
Cerrophidion (Bothrops) godmani myotoxins I (CGMT-I) and II (CGMT-II), Asp-49 and Lys-49 phospholipases A(2) (PLA2s), which drastically differ in enzymatic activity, were devoid of direct hemolytic effects on erythrocytes ...
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 ...
Stability of equine IgG antivenoms obtained by caprylic acid precipitation: Towards a liquid formulation stable at tropical room temperature
(2009-05)
Liquid formulations of antivenom require a cold chain for their distribution and storage, especially in tropical countries characterized by high temperature and humidity (climatic zone IV). Since cold chain is often deficient ...
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. ...
