Genetic comparison of breeding schemes based on semen importation and local breeding schemes: framework and application to Costa Rica
(American Dairy Science Association, 2004-05-01)
Local breeding schemes for Holstein cattle of Costa
Rica were compared with the current practice based
on continuous semen importation (SI) by deterministic
simulation. Comparison was made on the basis of ge-
netic ...
Analysis of test day yield data of Costa Rican dairy cattle
(Elsevier, 1998)
Estimates of variance components for test day
records in an animal model that considered multiple
traits over multiple lactations were calculated using
REML methodology. Test day records were classified
into 11 periods ...
Modeling extended lactations of dairy cows
(American Dairy Science Association, 2000-06)
Nine mathematical models were compared for their
ability to predict daily milk yields (n = 294,986) in stan-
dard 305-d and extended lactations of dairy cows of
Costa Rica. Lactations were classified by parity ...
Biologic and genetic characteristics of Toxoplasma gondii isolates in free-range chickens from Costa Rica, Central America
(Elsevier B.V, 2006-02-23)
The prevalence of Toxoplasma gondii in free-ranging chickens is a good indicator of the prevalence of T. gondii oocysts in the soil because chickens feed from the ground. The prevalence of T. gondii in 144 free-range ...
Dislipidemia y niveles de lípidos sanguíneos en pacientes tratados en centros de atención primaria de la Zona Este de San José, Costa Rica, año 2006
(Universidad Nacional, Costa Rica, 2010-12)
La dislipidemia, o sea, niveles elevados de lípidos sanguíneos (colesterol y triglicéridos), está estrechamente asociados con la
Enfermedad Cardiovascular (ECV). Conocer el perfil lipídico de una persona – y de una ...
Persistence of Brucella abortus lineages revealed by genomic characterization and phylodynamic analysis
(PLOS Neglected Tropical Diseases, 2020-04-14)
Brucellosis, caused by Brucella abortus, is a major disease of cattle and humans worldwide distributed. Eradication and control of the disease has been difficult in Central and South America, Central Asia, the Mediterranean ...
Exposure of dogs to Rickettsia spp. in Costa Rica: Risk factors for PCR-positive ectoparasites and seropositivity
(Elsevier, 2019-08-11)
Infection of dogs with Rickettsia spp. can result in inapparent, mild, or severe disease. Moreover,
common dog ticks and fleas are able to transmit rickettsiae to nearby humans. In this
study, the seroprevalence of spotted ...
Detection of antibodies against flavivirus over time in wild non-human primates from the lowlands of Costa Rica
(PLOS ONE, 2019-07-05)
Two-hundred-nine free ranging non-human primates from 31 locations throughout Costa
Rica were captured and released between 1993 and 2012, and blood samples, sera or
plasma were collected, to detect antigens and antibodies, ...
Nanofracturing: a new technique for bone marrow stimulation in equine cartilage repair
(Pferdeheilkunde, 2020-02-10)
Microfracture is the current standard in treatment of focal full-thickness cartilage lesions in horses, but clinical outcome may vary. Nanofracture is a novel technique that uses a commercially developed device to yield ...
Strain diversity of Rickettsia amblyommatis in ticks infesting birds in the North Huetar conservation area of Costa Rica
(Elsevier, 2019-06-10)
Although the presence of rickettsial agents in ticks infesting wild birds in Costa Rica has been recently reported,
information on strain diversity is limited to selected rickettsial species. In order to mine deeper into ...
