The effect of the dam–calf relationship on serostatus to Neospora caninum on 20 Costa Rican dairy farms
(Universidad Nacional, Costa Rica, 2003-03-31)
An epidemiological study was conduced on 20 dairy herds previously diagnosed as seropositive
for Neospora caninum. The number of females per farm varies from 41 to 296. All females present
on the farms were bled once in ...
BvrR/BvrS-controlled outer membrane proteins Omp3a and Omp3b are not essential for Brucella abortus virulence
(American Society for Microbiology, 2007-07-30)
The Brucella abortus two-component regulatory system BvrR/BvrS controls the expression of outer membrane proteins (Omp) Omp3a (Omp25) and Omp3b (Omp22). Disruption of bvrS or bvrR generates avirulent mutants with altered ...
Neutralizing antibodies against vesicular stomatitis viruses (serotypes New Jersey and Indiana) in horses in Costa Rica
(AAVLD, 2002-09-01)
Serum samples were collected from domestic horses in 4 different regions of Costa Rica to detect
antibodies against vesicular stomatitis viruses, serotypes New Jersey (VSV-NJ) and Indiana (VSV-IN). A total
of 214 samples ...
Epidemiología de la artritis encefalitis caprina en hatos caprinos lecheros de Costa Rica
(Universidad Nacional, Costa Rica, 2009)
El objetivo de este trabajo fue determinar aspectos epidemiológicos tales como seroprevalencia, incidencia y factores de riesgo asociados a la transmisión del virus de la artritis-encefalitis caprina (CAEV) en hatos caprinos ...
Factors associated with Neospora caninum serostatus in cattle of 20 specialised Costa Rican dairy herds
(Elsevier B.V, 2002-04-15)
Twenty-five specialised Costa Rican dairy farms (located in the Poás area) were used to determine neosporosis seroprevalence and the association of seropositivity with environmental and management factors. The farms involved ...
Serological Status for Chlamydophila psittaci, Newcastle Disease Virus, Avian Polyoma Virus, and Pacheco Disease Virus in Scarlet Macaws (Ara macao) Kept in Captivity in Costa Rica
(Blackwell Science, 2002-01-12)
From 1998 to 1999, a total of 128 blood samples were collected from scarlet macaws (Ara macao), kept in captivity in 11 different aviaries located in six provinces of Costa Rica. The sera were examined for antibodies ...
Response to the experimental inoculation of Sigmodon hispidus (Rodentia: Muridae) with vesicular stomatitis virus, New Jersey serotype
(Universidad Nacional, Costa Rica, 2009)
Sigmodon hispidus (cotton rat) was previously found to have antibodies against Vesicular Stomatitis Virus, New Jersey serotype (VSV-NJ) under field conditions in Costa Rica. In order to evaluate their response to the virus ...
Diversity of Human Rotavirus G and P Genotypes in Panama, Costa Rica, and the Dominican Republic
(The American Society of Tropical Medicine and Hygiene, 2008)
In this study 2,089 fecal samples from patients with gastroenteritis were analyzed from different hospitals
in Panama, Costa Rica, and the Dominican Republic during the period comprised between December 2002 and July
2003. ...
Field evaluation of a multiplex real-time reverse transcription polymerase chain reaction assay for detection of Vesicular stomatitis virus
(American Association of Veterinary Laboratory Diagnosticians, 2009)
Sporadic outbreaks of vesicular stomatitis (VS) in the United States result in significant
economic losses for the U.S. livestock industries because VS is a reportable disease that clinically mimics foot-
and-mouth ...
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 ...
