(Cambridge University Press, 2023-02-20)The Mermithidae is a family of nematodes parasitic in many kinds of insects, spiders, leeches, crustaceans and other invertebrates throughout the world. While conducting an assay with entomopathogenic nematodes, we found ... -
Age‑performance and intensity of grooming behavior toward Varroa destructor in resistant and susceptible Apis mellifera colonies
(Springer, 2022-10)Grooming behavior confers resistance to honey bees against Varroa destructor, being of interest to social immunity studies and breeding programs. The objective of this study was to characterize at the individual level the ... -
Agroinoculation of a full-length cDNA clone of cotton leafroll dwarf virus (CLRDV) results in systemic infection in cotton and the model plant Nicotiana benthamiana
(2013-07)Cotton blue disease is the most important viral disease of cotton in the southern part of South America. Its etiological agent, cotton leafroll dwarf virus (CLRDV), is specifically transmitted to host plants by the aphid ... -
Aislamiento de Mycobacterium intracellulare a partir de un pulmón bovino comercializado en una carnicería de la zona oeste del conurbano bonaerense = Isolate of Mycobacterium intracellulare from a bovine lung marketed in a butcher shop from western of Greater Buenos Aires
(Facultad de Ciencias Veterinarias, Universidad de Buenos Aires, 2016)Se realizó un muestreo de 62 pulmones bovinos en una carnicería y un frigorífico de la zona oeste del conurbano bonaerense. De uno de ellos, adquirido en una carnicería, y sin lesiones visibles compatibles con tuberculosis, ... -
Aislamiento y caracterización de regiones promotoras de girasol para dirigir la expresión tejido específica de genes foráneos a semilla
(Facultad de Ciencias Exactas y Naturales, Universidad de Buenos Aires, 2014-04)Desde el inicio de la utilización de variedades transgénicas, la superficie agrobiotecnológica ha aumentado exponencialmente, con un incremento del orden de 80 veces en solo 14 años, y su uso se ha expandido a más de veinte ... -
Alfalfa snakin-1 prevents fungal colonization and probably coevolved with rhizobia
(BMC Plant Biology, 2014-09-17)Background: The production of antimicrobial peptides is a common defense strategy of living cells against a wide range of pathogens. Plant snakin peptides inhibit bacterial and fungal growth at extremely low concentrations. ... -
Allelic differences in a vacuolar invertase affect Arabidopsis growth at early plant development
(2016)Improving carbon fixation in order to enhance crop yield is a major goal in plant sciences. By quantitative trait locus (QTL) mapping, it has been demonstrated that a vacuolar invertase (vac-Inv) plays a key role in ... -
Alteraciones neuroinmunes inducidas por exposición a estrés prenatal. Participación de citoquinas y neurotrofinas. Influencia del sexo de la cría
(Facultad de Ciencias Exactas y Naturales, Universidad de Buenos Aires, 2015)En el presente trabajo estudiamos el efecto del estrés prenatal (EP) en la respuesta neuroinmune en animales adultos. Observamos que machos y hembras respondieron diferente ante el EP, tanto a nivel inmunológico como ... -
An applied printing immunoassay with recombinant Nc-SAG1 for detection of antibodies to Neospora caninum in cattle
(Sage Publishing, 2011-08)Neospora caninum is a protozoan parasite that causes an important reproductive disease in cattle. Neospora caninum surface antigen 1 (Nc-SAG1) is an immunodominant candidate for the development of a diagnostic reagent for ... -
An efficient vaccine against bovine leukemia virus
(BioMed Central, 2015)Previous attempts to produce a vaccine against BLV faced problems of efficacy (i.e. only a fraction of animals were protected), persistence (i.e. rapid decrease of immune protection), cost (e.g. production of purified ... -
An improved DNA vaccine against bovine herpesvirus-1 using CD40L and a chemical adjuvant induces specific cytotoxicity in mici
(Mary Ann Liebert, 2021-03)Bovine herpesvirus-1 (BoHV-1) uses many mechanisms to elude the immune system; one of them is spreading intracellularly, even in the presence of specific antiviral antibodies. Cytotoxic T lymphocytes (CTLs) are necessary ... -
An inhibitory mechanism of action of coiled‐coil peptides against type three secretion system from enteropathogenic Escherichia coli
(Wiley, 2019-03)Human pathogenic gram‐negative bacteria, such as enteropathogenic Escherichia coli (EPEC), rely on type III secretion systems (T3SS) to translocate virulence factors directly into host cells. The coiled‐coil domains present ... -
An inoculant Bradyrhizobium strain with increased motility improves yield of soybean crops
(Asociación Argentina de Microbiología, 2021-09-15)Soybean production is very important in Argentina, where more than 20 million hectares are sowed annually with this crop. Since soybean plants possess a very high N-demand, it is crucial that this agricultural activity is ... -
