Brucella abortus is an intracellular pathogen of monocytes, macrophages, dendritic cells, and placental trophoblasts. This bacterium causes a chronic disease in bovines and in humans. In these hosts, the bacterium also ...

Cancer complexity and resistance is mediated by cell-to-cell heterogeneity, which is the consequence of the enormous instability of its genetic material. It is unknown how cancer cells are able to withstand the effects ...

Brucellosis is a bacterial infectious disease affecting a wide range of mammals and a neglected zoonosis caused by species of the genetically homogenous genus Brucella. As in most studies on bacterial diseases, research ...

Introducción: el dengue y chikungunya son virosis antroponóticas transmitidas por Aedes aegypti que afectan extensas áreas del continente americano incluyendo Costa Rica. La reciente introducción del virus Zika representa ...

Background: Biopiracy mainly focuses on the use of biological resources and/or knowledge of indigenous tribes or communities without allowing them to share the revenues generated out of economic exploitation or other ...

Introducción. En Costa Rica, el dengue es la principal enfermedad de trasmisión vectorial. Esta afecta ecosistema urbanos como La Carpio y La Gran Puntarenas, donde Aedes aegypti es altamente prevalente. Objetivo. Reevaluar ...

Se realizó un estudio transversal con el objetivo de determinar la prevalencia de fasciolosis en bovinos sacrificados en mataderos de Costa Rica y comparar cuatro técnicas diagnósticas disponibles (inspección macroscópica ...

Arbovirus of the genus Alphavirus and Flavivirus can cause febrile illness and sometimes neurological disease in both humans and animals. West Nile Virus (WNV), Eastern Equine Encephalitis Virus (EEEV), Western Equine ...

Outbreaks of spotted fevers have been reported in Costa Rica since the 1950s, although vectors responsible for transmission to humans have not been directly identified. In this study, species of Rickettsia were detected ...

t IgG responses are fundamental to adaptive immunity and document immunological memory of previous pathogen encounter. While specific antigen recognition is mediated by the variable F(ab′)2 domain of IgG, various effector ...
