Brucella neotomae infection in humans, Costa Rica
(Emerging Infectious Diseases, 2017-06)
Several species of Brucella are known to be zoonotic, but B. neotomae infection has been thought to be limited to wood rats. In 2008 and 2011, however, B. neotomae was isolated from cerebrospinal fluid of 2 men with ...
Serology, molecular detection and risk factors of Ehrlichia canis infection in dogs in Costa Rica
(Ticks and Tick-borne Diseases, 2016-10-06)
A cross-sectional study combining different serological and molecular techniques for the detection of Ehrlichia species in dogs and their ticks was carried out with data from all regions of Costa Rica. A seroprevalence of ...
Efecto del estatus serológico al virus de la leucosis enzoótica bovina (BLV) sobre la producción de leche en hatos lecheros de Costa Rica
(Universidad Nacional, Costa Rica, 2012-09-02)
Se realizó un estudio longitudinal para determinar el efecto del estatus serológico
al virus de la leucosis enzoótica bovina (BLV) sobre la producción de leche en hatos lecheros
especializados de Costa Rica. Se analizó ...

(Universidad Nacional, Costa Rica, 2016-11-30)
Background: A cross-sectional study combining different serological and molecular
techniques for the detection of Ehrlichia canis in dogs was carried out to determine
hemopathological findings and suggestive clinical ...
Apparent lack of evidence on selected infectious agents in wild Yellow-naped Amazon parrots: implications for releasing attempts
(Universidad Nacional, Costa Rica, 2015-05-09)
Blood and feather samples, as well as oropharyngeal and cloacal swabs, were collected
from nine free-ranging Amazona auropalliata between January and May 2009 in two highly
modified landscapes in northern Costa Rica. ...
Brucella abortus strain 2308 Wisconsin genome: Importance of the definition of reference strains
(Frontiers in Microbiology, 2016-09-29)
La brucelosis es una enfermedad infecciosa bacteriana que afecta a una amplia gama de mamíferos y una zoonosis desatendida causada por especies del género genéticamente homogéneo Brucella. Como en la mayoría de los estudios ...
Neutrophils dampen adaptive immunity in Brucellosis
(American Society For Microbiology, 2019-04-23)
Brucella organisms are intracellular stealth pathogens of animals and humans. The bacteria overcome the assault of innate immunity at early stages of an infection. Removal of polymorphonuclear neutrophils (PMNs) at the ...
The potential use of Rattus norvegicus (Mammalia, Muridae) in experimental infections with metacercariae of Paragonimus mexicanus (Digenea, Troglotematidae)
(Universidad Nacional, Costa Rica, 2017-01-15)
Seven Wistar rats (Rattus norvegicus) were experimentally infected with Paragonimus mexicanus
metacercariae, obtained from organs and tissues of freshwater crabs (Brachyura: Pseudothelphusidae) collected from the Caribbean ...
Emergence of an outbreak-associated Clostridium difficile variant with increased virulence
(Journal of Clinical Microbiology, 2015-04-23)
The prevalence of Clostridium difficile infections has increased due to the emergence of epidemic variants from diverse genetic lineages. Here we describe the emergence of a novel variant during an outbreak in a Costa Rican ...
Brucella canis is an intracellular pathogen that induces a lower proinflammatory response than smooth zoonotic counterparts
(Infection and Immunity, 2015-09-29)
Canine brucellosis caused by Brucella canis is a disease of dogs and a zoonotic risk. B. canis harbors most of the virulence determinants defined for the genus, but its pathogenic strategy remains unclear since it has not ...
