Activation of Rho and Rab GTPases dissociates Brucella abortus internalization from intracellular trafficking
(Blackwell Science, 2002-10-04)
Brucella abortus is an intracellular pathogen that relies on unconventional virulence factors to infect hosts. In non-professional phagocytes, Rho GTPasesactivation by the Escherichia coli cytotoxic necrotiz ing factor ...
The two-component system BvrR BvrS essential for Brucella abortus virulence regulates the expression of outer membrane proteins with counterparts in members of the Rhizobiaceae
(Proceedings of the National Academy of Sciences, 2002-09-17)
The Brucella BvrR/BvrS two-component regulatory system is homologous to the ChvI/ChvG systems of Sinorhizobium meliloti and Agrobacterium tumefaciens necessary for endosymbiosis and pathogenicity in plants. BvrR/BvrS ...
Presencia de anticuerpos neutralizantes contra el virus de estomatitis vesicular (serotipos New Jersey e Indiana) en personas residentes en dos zonas lecheras de Costa Rica
(Universidad Nacional, Costa Rica, 2002-12)
La primera parte de esta investigación tuvo como objetivo determinar la prevalencia de anticuerpos contra el virus de estomatitis vesicular, serotipos New Jersey e Indiana, en la población humana de las regiones lecheras ...
Regulation of Brucella virulence by the two-component system BvrR/BvrS
(Elsevier B.V., 2002-12-20)
The Brucella BvrR/BvrS two-component regulatory system is highly similar to the regulatory and sensory proteins of Sinorhizobium and Agrobacterium necessary for endosymbiosis and pathogenicity in plants, and very similar ...
Comparison of the serum neutralization test and a competitive enzyme-linked immunosorbent assay for the detection of antibodies to vesicular stomatitis virus New Jersey and vesicular stomatitis virus Indiana
(AAVLD, 2002-05-01)
A competitive enzyme-linked immunosorbent assay (C-ELISA) for the detection of antibodies against
vesicular stomatitis virus New Jersey (VSV-NJ) and vesicular stomatitis virus Indiana (VSV-IN) was compared with
the serum ...
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 ...
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 ...
Chagas disease in dogs from endemic areas of Costa Rica
(Memórias do Instituto Oswaldo Cruz, 2002-06)
Dogs with the presumptive diagnosis of Chagas disease are commonly sent to our School of Veterinary Medicine by independent veterinarians. This prompted us to evaluate the prevalence of canine trypanosomiasis in some ...
Childhood leukaemia in Costa Rica, 1981-96
(Blackwell Science, 2002)
Childhood leukaemia incidence in Costa Rica during 1981-96, among the highest in the world, was analysed by histology, gender, birth year, time period of diagnosis, age at diagnosis and region. Numbers of cases were extracted ...
