Vaccination against babesiosis using recombinant GPI-anchored proteins
(Elsevier, 2019-01)The increase in human babesiosis is of major concern to health authorities. In the USA, most of these cases are due to infections with Babesia microti, whereas in Europe B. divergens is the major cause of clinical disease ... -
Vaccination against δ-retroviruses : the bovine leukemia virus paradigm
(2014-06)Bovine leukemia virus (BLV) and human T-lymphotropic virus type 1 (HTLV-1) are closely related d-retroviruses that induce hematological diseases. HTLV-1 infects about 15 million people worldwide, mainly in subtropical ... -
Vaccination of pigs with the S48 strain of Toxoplasma gondii – safer meat for human consumption
(2015)As clinical toxoplasmosis is not considered a problem in pigs, the main reason to implement a control strategy against Toxoplasma gondii (T. gondii) in this species is to reduce the establishment of T. gondii tissue cysts ... -
A vaccine using Anaplasma marginale subdominant type IV secretion system recombinant proteins was not protective against a virulent challenge
(PLOS; National Center for Biotechnology Information, 2020-02)Anaplasma marginale is the most prevalent tick-borne livestock pathogen with worldwide distribution. Bovine anaplasmosis is a significant threat to cattle industry. Anaplasmosis outbreaks in endemic areas are prevented via ... -
Vaccines against bovine babesiosis: where we are now and possible roads ahead
(Cambridge University Press, 2014-10)Bovine babesiosis caused by the tick-transmitted haemoprotozoans Babesia bovis, Babesia bigemina and Babesia divergens commonly results in substantial cattle morbidity and mortality in vast world areas. Although existing ... -
Vacuna “marcadora” contra el HVB-1
(Gerencia de Comunicación e Imagen Institucional, DNA SICC, INTA, 2011-04)Investigadores del INTA trabajaron en el desarrollo de un producto que previene una enfermedad que provoca importantes pérdidas económicas y que permite diferenciar entre animales vacunados e infectados. -
Vaginal histological changes after using intravaginal sponges for oestrous synchronization in anoestrous ewes
(Wiley, 2015-04)To characterize the histological and cytological vaginal changes generated by the use of intravaginal sponge (IS) applied in oestrous synchronization treatments in ewes during mid‐non‐breeding season. Thirty‐five multiparous ... -
Vaginal mucus from ewes treated with progestogen sponges affects quality of ram spermatozoa
(2016)The use of intravaginal sponges (IS) to synchronize estrous onset in ewes provokes vaginitis, an increase in the vaginal bacterial load, and growth of bacterial species that are not present during spontaneous estrous ... -
Valeriana gaimanensis (Valerianaceae nom. conserv.), a New Species from the Patagonian Semi-Arid Desert, Argentina
(American Society of Plant Taxonomists, 2016-02)Valeriana gaimanensis, a new species from Argentinean Patagonia, is described and illustrated. The new species belongs to the subgenus Valeriana and is apparently endemic to the Extra-Andean Patagonia region, where it grows ... -
Validación de irradiación para reducir la presencia de Escherichia coli productor de toxina Shiga en carne picada fresca.
(2019-09)Escherichia coli productor de toxina Shiga (STEC) es el agente causal de diarreas con o sin sangre y, en los casos más severos, del Síndrome Urémico Hemolítico. La carne picada ha sido descripta como uno de los principales ... -
Validación de sistemas de pronóstico del impacto de la fusariosis de la espiga en cultivares de trigo
(2016-07)En Argentina, el principal agente causal de la enfermedad conocida como fusariosis de la espiga de trigo (FET) es el hongo Fusarium graminearum (Schwabe) (teleomorfo Gibberella zeae (Schwein)). La FET es una enfermedad ... -
Validación de un método de selección para rendimiento en alfalfa basado en la depresión por endocría
(Facultad de Ciencias Agropecuarias, Universidad Nacional de Córdoba, 2011)La rápida depresión por endocría en alfalfa obedece a la pérdida de interacciones alélicas intra-locus en plantas tri y tetra alélicas. Éstas podrían identificarse por una prueba de autofecundación y luego combinarse en ... -
Validación del Cociente Fototermal como predictor del rendimiento potencial de diferentes genotipos de trigo en el Norte de la provincia de Santa Fe
(Facultad de Ciencias Agrarias, Universidad Nacional del Nordeste, 2011)Las variaciones en el número de granos por unidad de superficie (NG) de trigo, principal componente del rendimiento, han sido interpretadas como una función directa de la radiación incidente fotosintéticamente activa e ... -
