Impacto de la Pandemia por SARS-CoV2 sobre la Educación
(Universidad Nacional, Costa Rica, 2020-12-01)
Se describe el impacto de la pandemia por SARS-CoV2 sobre la educación y se propone
algunos escenarios donde la Universidad Nacional puede contribuir a mitigar el daño y a participar
en la construcción del escenario ...
Isolierung von Coronaviren in der Zellkultur aus Nasentupferproben atemwegskranker Kalber in der Bundesrepublik Deutschland
(Paul Parey Scientific Publishers, 1989)
Isolation in tissue culture of coronavirus from respiratory diseased calves in the FRG
Coronavirus was isolated in HRT-IS tissue culture from nasal swabs of 4 from 15 calves showing
respiratory symptoms. The strains ...
Absence of IgG antibodies against Schmallenberg virus in ruminant sera (bovine, goat and sheep) collected in Costa Rica between 2012 and 2014.
(Universidad Nacional, Costa Rica, 2017-07)
Schmallenberg virus affects ruminants, which causes significant economic losses. The virus is transmitted
through vectors of the genus Culicoides; however, other studies do not rule out the possibility of sexual
transmission ...
Neotropical bats from Costa Rica harbour diverse coronaviruses
(Blackwell, 2015)
Bats are hosts of diverse coronaviruses (CoVs) known to potentially cross the
host–species barrier. For analysing coronavirus diversity in a bat species-rich
country, a total of 421 anal swabs/faecal samples from Costa ...
Seroprevalence and risk factors for equine arboviral infections (Eastern Equine Encephalomyelitis, Western Equine Encephalomyelitis, Venezuelan Equine Encephalomyelitis and West Nile Fever) in Costa Rica
(Elsevier, 2016)
To gain a better understanding of the epidemio-
logical situation of arboviral infections in horses in Costa Rica,
a national IgG seroprevalence study was performed in 2013. In
Costa Rica, equine arboviral infections ...
Extensive Cell Envelope Modulation Is Associated with Virulence in Brucella abortus
(American Chemical Society, 2007-08-03)
Brucella virulence is linked to components of the cell envelope and tightly connected to the function of
the BvrR/BvrS sensory-regulatory system. To quantify the impact of BvrR/BvrS on cell envelope proteins,
we performed ...
Fine-scale variation in vector host use and force of infection drive localized patterns of West Nile virus transmission
(PLOS ONE, 2011-08-19)
The influence of host diversity on multi-host pathogen transmission and persistence can be confounded by the large
number of species and biological interactions that can characterize many transmission systems. For ...
Assessing changing weather and the El Niño Southern Oscillation impacts on cattle rabies outbreaks and mortality in Costa Rica (1985–2016)
(BMC Veterinary Research, 2018-09-17)
Background: Rabies is a major zoonotic disease affecting humans, domestic and wildlife mammals. Cattle are the
most important domestic animals impacted by rabies virus in the New World, leading to thousands of cattle ...
Globally invasive, withdrawing at home: Aedes albopictus and Aedes japonicus facing the rise of Aedes flavopictus
(Springer, 2016)
It has been suggested that climate change may have
facilitated the global expansion of invasive disease vectors,
since several species have expanded their range as tempera tures have warmed. Here, we present results from ...
Isolation, detection and characterization of swine hepatitis E virus from herds in Costa Rica
(Taylor & Francis, 2008-06)
Although swine HEV isolates from North America, Europe, and Asia have been
genetically characterized, little is known about the strains presumed to be circulating in
Latin America. In this study, seven commercial swine ...
